Interview with Finnish pulmonologist Dr. Alexander van Assendelft on airborne transmission during the COVID-19 pandemic (I would like to say that even if it’s not possible anymore to get rid of this pandemic because of the extremely transmissible Omicron mutations, it would still make a great difference if people realized that the most dangerous part in encountering others is when they are talking. By minimizing discussions indoors, maintaining distance and wearing good masks, then it is possible to decrease your risks considerably from getting COVID. Everybody can do something to protect themselves and others. ). World Socialist Web Site. 18.9.2023.

Trends in invasive bacterial diseases during the first 2 years of the COVID-19 pandemic: analyses of prospective surveillance data from 30 countries and territories in the IRIS Consortium (COVID-19 containment measures were associated with a sustained decrease in the incidence of invasive disease caused by S pneumoniae, H influenzae, and N meningitidis during the first 2 years of the pandemic, but cases began to increase in some countries towards the end of 2021 as pandemic restrictions were lifted. These IRIS data provide a better understanding of microbial transmission, will inform vaccine development and implementation, and can contribute to health-care service planning and provision of policies.).

New Study Detects Spike Protein 6 Months After COVID-19 Vaccination. (According to CDC, mRNA from COVID-19 vaccines is “broken down within a few days after vaccination and doesn’t last long in the body”—a position it has adhered to since the pandemic’s beginning, despite research suggesting otherwise (pdf). The CDC refers to mRNA as “messenger RNA,” whereas regulatory documents and Pfizer refer to the mRNA in COVID-19 vaccines as “modified RNA.” However.

Covid may have permanently damaged people’s immunity (New Zealand. Several international studies – involving millions of people, mainly from before vaccines became widely available – found a Covid infection doubled the risk of developing heart disease and increased the chance of stroke 1.6 fold. It was also associated with higher rates of both type 1 and type 2 diabetes. “There are a lot of long-term sequelae to Covid that we don’t really know yet and we may not know for years,” Payinda said. “Post polio syndromes were not identified for literally decades after polio infections. The same with the 1918 flu epidemic – people born during the 1918 Spanish flu epidemic had a two- to three-fold increased risk of later developing Parkinson’s Disease.” The latest research showed vaccination halved the risk of cardiac problems post-infection, he said.).  1 news. 13.9-2023.

When Did “Herd Immunity” Become a Taboo Phrase

(Doctors who repeatedly predicted herd immunity in 2020 and 2021, mocking and berating those who disagreed, now treat herd immunity as a taboo phrase. Jonathan Howard, GBD, Martin Kulldorf, Jay Bhattacharya:

  • Herd immunity for coronaviruses means a widescale decoupling of cases from deaths caused by the virus due to immunity.

However, most doctors who spoke ceaselessly about herd immunity in 2020 and 2021, refuse to do so today. In fact, they act as if they had never mentioned herd immunity at all. There has been scant acknowledgement that their preposterous predictions of the pandemic’s end failed to arrive. They’ve made made no effort to grapple with the real-world consequences of telling people herd immunity was around the corner, when in fact the worst was yet to come. Instead of reflecting on their previous claims of herd immunity, these doctors now encourage repeat mass infection, saying:

  • Repeat infections are inevitable. More the longer you live. Nothing can be done about it. 

And thus it becomes clear, doctors who previously mocked and berated those who supposedly treated herd immunity as a taboo phrase, now treat herd immunity, as they defined it in 2021, as a taboo phrase. As cases and hospitalizations rise once again, I wonder why that is).

Comparative study showed that children faced a 78% higher risk of new-onset conditions after they had COVID-19 (We compared 1656 exposed and 1656 unexposed children from 1 February 2020 to 30 November 2021. The overall excess risk for new-onset conditions after COVID-19 was 78% higher in the exposed than unexposed children. We found significantly higher risks for some new conditions in exposed children, including mental health issues (aHR 1.8, 95% CI 1.1–3.0) and neurological problems (aHR 2.4, 95% CI 1.4–4.1).). Acta Paediatrica. 9.9.2023.

Covid-19 linked to elevated risk of type 1 diabetes in young children (Children between the ages of 4 months and 2 years seem more likely to have antibodies that attack insulin-producing cells, a feature of type 1 diabetes, if they have had covid-19, which may show how viral infections can lead to this type of diabetes).

COVID patients breathe large amounts of virus early on. Northwestern investigators collect samples over the entire course of infection to determine when a person is most infectious (On day eight, exhaled levels of virus drop steeply, down to near the limit of detection — an average of two copies exhaled per minute. / Mild and moderately symptomatic patients with COVID still exhale large amounts of virus, though severely symptomatic cases exhale higher levels on average, the study reports. / Vaccinated and unvaccinated patients exhale similar levels of virus over the course of infection, the research shows. / The amount of virus being exhaled while infected was the same no matter which variant a person was infected with — people infected with Alpha exhaled just as much as those infected with Omicron, the study reports.). Northwestern Now. 8.9.2023.

Quantity of SARS-CoV-2 RNA copies exhaled per minute during natural breathing over the course of COVID-19 infection (…numbers of exhaled SARS-CoV-2 RNA copies during COVID-19 infection do not decrease significantly until day 8 from symptom-onset.

Global Trends in Highly Cited Studies in COVID-19 Research (This cross-sectional study found that the number of highly cited studies peaked at 1292 studies at the end of 2021 and declined to 649 studies at the end of 2022. Highly cited studies from China showed a decreasing trend, while those from the US and UK showed an increasing trend. These findings suggest that as the COVID-19 pandemic evolved in the 3 years since its outbreak, there were important shifts in trends of the number and origin of high-profile COVID-19 studies.).

Determinants of the onset and prognosis of the post-COVID-19 condition: a 2-year prospective observational cohort study (The study included 548 individuals, 341 with PCC, followed for a median of 23 months (IQR 16.5–23.5), and 207 subjects fully recovered. In the model with the best fit, subjects who were male and had tertiary studies were less likely to develop PCC, whereas a history of headache, or presence of tachycardia, fatigue, neurocognitive and neurosensitive complaints and dyspnea at COVID-19 diagnosis predicted the development of PCC. The cluster analysis revealed the presence of three symptom clusters with an additive number of symptoms. Only 26 subjects (7.6%) recovered from PCC during follow-up; almost all of them (n = 24) belonged to the less symptomatic cluster A, dominated mainly by fatigue. Recovery from PCC was more likely in subjects who were male, required ICU admission, or had cardiovascular comorbidities, hyporexia and/or smell/taste alterations during acute COVID-19. Subjects presenting with muscle pain, impaired attention, dyspnea, or tachycardia, conversely, were less likely to recover from PCC.). The Lancet Regional Health – Europe. 5.9.2023.

Scientists Sound the Alarm: COVID-19 Virus Is Rapidly Evolving in White-Tailed Deer (Genomic analysis showed that at least 30 infections in deer had been introduced by humans – a figure that surprised the research team. “We generally talk about interspecies transmission as a rare event, but this wasn’t a huge sampling, and we’re able to document 30 spillovers. It seems to be moving between people and animals quite easily,” said Andrew Bowman, associate professor of veterinary preventive medicine at The Ohio State University and co-senior author of the study. “And the evidence is growing that humans can get it from deer – which isn’t radically surprising. It’s probably not a one-way pipeline.”). SciTechDaily. 29.8.2023.

Opinion Everyone should know the dangers of long covid (Given these [Long Covid] findings, I am confused as to why CDC  and our local public health authorities in Montgomery County and elsewhere in Maryland are not widely sharing information about the risks of long covid, encouraging us to prevent every possible infection and mandating — or at the very least encouraging — universal masking protections in health-care settings. … High-quality masks and ventilation can help us reduce the likelihood of these serious health outcomes and are especially important in essential spaces such as health-care settings.). Washington Post. 27.8.2027.

Hundreds of hospital wards closed due to Covid outbreaks (At least 237 wards were closed to new admissions – typically for periods of around seven to 10 days – in a bid to prevent the virus spreading to other patients. That compares to a total of 93 ward closures up to the end of July for all other infection control incidents combined, including cases of norovirus, flu, RSV, or gastroenteritis.). The Herald/Scotland. 25.8.2023.

As schools resume, CDC reports new rise in COVID emergency room visits from adolescents (The increase comes as schools and businesses are now weighing a return to masks and other precautions to curb the virus, amid a weeks-long rise in new COVID-19 hospitalizations nationwide that is projected to continue. Officials are also now tracking a new, highly-mutated COVID-19 variant called BA.2.86 that experts think might fuel further spread.). CBC News. 25.8.2023.

Lockdowns and face masks really did help to control covid-19.
(Non-vaccine measures such as social distancing and wearing face masks have been “unequivocally effective” at preventing the spread of the SARS-CoV-2 coronavirus, according to a major report by the UK’s Royal Society). New Scientist. 24.8.2023.

Effectiveness of social distancing measures and lockdowns for reducing transmission of COVID-19 in non-healthcare, community-based settings (Re. masks/schools: Four of the six observational studies assessed individual schools between the end of 2020 and early 2021. Three did not quantify the effect but observed minimal transmission in schools with SDMs and universal masking interventions in place despite substantial community transmission . The remaining study that examined the effect of multiple distancing measures in 36 schools in Italy (including limited capacity, distanced student desks and minimized crowding and entry and exits) observed that the overall secondary transmission rate was 3.8%, although there was no comparator without the interventions in place. Two other observational studies had similar findings. One that used data from 35 school outbreaks across 12 countries from 2020 to July 2021 suggested that distancing and masking were both associated with a lower risk of SARS-CoV-2 infection in schools (adjusted odds ratio (aOR): 0.30, 95% CI: 0.25, 0.37). Another ecological study examining schools in North Carolina and Wisconsin, US, from 2020 to 2021 did not observe an increase in the secondary transmission rate in schools after distancing measures were relaxed, indicating they had no effect on transmission in these schools . The remaining simulation studies found that school measures were associated with reductions in public health impacts of COVID-19, both in the schools and the community.).

Medical News in Brief: Two New Analyses Add to Long COVID Understanding (Overall, the prevalence of post–COVID-19 condition, or long COVID (LC), has declined among US adults. In June 2023, 11% of participants with a previous SARS-CoV-2 infection reported currently having LC, compared with 19% at 12 months prior. Prevalence of LC among all US adults also decreased, from 7.5% to 6%. / The decline in prevalence plateaued by this January. Among those who reported having LC this June, 1/4 said they had a significant activity limitation (MMWR). / Another study in MMWR found that LC-like symptoms may not be unique to COVID-19. It used data from the CDC-funded Innovative Support for Patients with SARS-CoV-2 Infections Registry, or INSPIRE, multicenter cohort study. / This analysis looked at the prevalence over time of LC-like symptoms among 1296 adults who had a COVID-like illness. A substantial proportion of both those who had a positive SARS-CoV-2 PCR or antigen test result and those who tested negative reported symptoms at 3 months—about 48% and 38%, respectively. Both groups also reported symptoms that emerged or reemerged over the following 9 months. /Persistent symptoms decreased over time in both groups. By month 12, the prevalence of long COVID-like symptoms was similar between the groups, reported by about 18% of people with a positive test result and about 16% of people with a negative test result.).

Omicron infection following vaccination enhances a broad spectrum of immune responses dependent on infection history (We find that most individuals increase BA.1/BA.2/BA.5-specific neutralizing antibodies following infection, but confirm that the magnitude of increase and post-omicron titres are higher in the infection-naive. In contrast, significant increases in nasal responses, including neutralizing activity against BA.5 spike, are seen regardless of infection history. Spike-specific T cells increase only in infection-naive vaccinees; however, post-omicron T cell responses are significantly higher in the previously-infected, who display a maximally induced response with a highly cytotoxic CD8+ phenotype following their 3rd mRNA vaccine dose. Responses to non-spike antigens increase significantly regardless of prior infection status. These findings suggest that hybrid immunity induced by omicron breakthrough infections is characterized by significant immune enhancement that can help protect against future omicron variants.). nature communications. 21.8.2023.

Covid-19: Leaked cremation data hint at true scale of China’s death rate (In the relatively wealthy and developed eastern province, where more than 99% of all deaths end in cremation, the number of cremations in the first quarter of 2023 was just under 171 000, compared with 99 000 in the first quarter of 2022 and 90 000 in the first quarter of 2021.  Extrapolated across China, this 72% rise in mortality would translate to about 1.5 million excess deaths in the first quarter of 2023, closely matching predictions of several models developed by epidemiologists).

Deficits were largest for positive individuals with ≥12 weeks of symptoms (N = 495, β = −0.22 SDs, 95% CI: −0.35, −0.09). Effects were comparable to hospital presentation during illness (N = 281, β = −0.31 SDs, 95% CI: −0.44, −0.18), and 10 years age difference (60–70 years vs. 50–60 years, β = −0.21 SDs, 95% CI: −0.30, −0.13) in the whole study population. Stratification by self-reported recovery revealed that deficits were only detectable in SARS-CoV-2 positive individuals who did not feel recovered from COVID-19, whereas individuals who reported full recovery showed no deficits. Longitudinal analysis showed no evidence of cognitive change over time, suggesting that cognitive deficits for affected individuals persisted at almost 2 years since initial infection.). eClinicalMedicine. 21.7.2023.

Disentangling the Postacute Sequelae of SARS-CoV-2. E Unibus Pluram (From One, Many) (This first RECOVER adult cohort study report provides an important initial framework for defining the sequelae that manifest after acute SARS-CoV-2 infection. The research exemplifies the benefits of multidisciplinary collaboration informed by extensive input from patient representatives. These efforts will continue to be needed to determine whether this phenomenon represents one entity with a single definition or multiple phenotypes that arise after COVID-19 infection requiring separate case definitions (ie, E unibus pluram [from one, many]). Addressing this question and finalizing the definitions of these postacute sequelae should facilitate more robust research that ultimately leads to high-quality care and treatment for patients with late effects of SARS-CoV-2 infection.).

Positive correlations were observed between the age of the participants in almost all the tasks assessed, implying better performance and milder impairment with increasing age.

Memory loss in patients with long COVID can be due to reduced hippocampal neurogenesis (Therefore, the reduced neurogenesis, which was shown in the COVID-19 group, could be due to microglial activation and the subsequent production of inflammatory cytokines, such as TNF-α, IL-6, and IL-1β, causing neuroinflammation and the resultant impaired neurogenesis. This eventually results in cognitive decline due to the destruction of spatial memory and learning. These implications on the hippocampus, especially the loss of hippocampal neurogenesis in the brains of COVID-19 patients, elucidate learning, memory, and executive impairments in COVID-19 patients compared with uninfected healthy controls).

Spheromers reveal robust T cell responses to the Pfizer/BioNTech vaccine and attenuated peripheral CD8+ T cell responses post SARS-CoV-2 infection (T cells are a critical component of the response to SARS-CoV-2, but their kinetics after infection and vaccination are insufficiently understood. Using “spheromer” peptide-MHC multimer reagents, we analyzed healthy subjects receiving two doses of the Pfizer/BioNTech BNT162b2 vaccine. Vaccination resulted in robust spike-specific T cell responses for the dominant CD4+ (HLA-DRB1∗15:01/S191) and CD8+ (HLA-A∗02/S691) T cell epitopes. Antigen-specific CD4+ and CD8+ T cell responses were asynchronous, with the peak CD4+ T cell responses occurring 1 week post the second vaccination (boost), whereas CD8+ T cells peaked 2 weeks later. These peripheral T cell responses were elevated compared with COVID-19 patients. We also found that previous SARS-CoV-2 infection resulted in decreased CD8+ T cell activation and expansion, suggesting that previous infection can influence the T cell response to vaccination.).

Statement on ‘Physical interventions to interrupt or reduce the spread of respiratory viruses’ review (Many commentators have claimed that a recently-updated Cochrane Review shows that ‘masks don’t work’, which is an inaccurate and misleading interpretation. / It would be accurate to say that the review examined whether interventions to promote mask wearing help to slow the spread of respiratory viruses, and that the results were inconclusive. Given the limitations in the primary evidence, the review is not able to address the question of whether mask-wearing itself reduces people’s risk of contracting or spreading respiratory viruses. / The review authors are clear on the limitations in the abstract: ‘The high risk of bias in the trials, variation in outcome measurement, and relatively low adherence with the interventions during the studies hampers drawing firm conclusions.’ Adherence in this context refers to the number of people who actually wore the provided masks when encouraged to do so as part of the intervention. For example, in the most heavily-weighted trial of interventions to promote community mask wearing, 42.3% of people in the intervention arm wore masks compared to 13.3% of those in the control arm. / The original Plain Language Summary for this review stated that ‘We are uncertain whether wearing masks or N95/P2 respirators helps to slow the spread of respiratory viruses based on the studies we assessed.’ This wording was open to misinterpretation, for which we apologize. While scientific evidence is never immune to misinterpretation, we take responsibility for not making the wording clearer from the outset.

Airborne transmission: a new paradigm with major implications for infection control and public health (In the longer term, the Government needs to lead with building codes in residential and commercial sectors that treat clean air provision with as much importance as earthquake safety.
The removal of non-pharmaceutical public health interventions (such as mask wearing
requirements in public spaces) makes the use of engineering controls to minimise exposure to contaminated air even more important. Improving indoor air quality will not only reduce COVID-related illness, but all morbidity related to poor air quality. With this in mind, it’s understandable that reliably maintaining high indoor air quality standards has been described as the new “sanitation). New Zealand Medical Journal. 17.2.2023.

But the ‘worst case’ possibility of a new coronavirus exists (There exists a popular belief that Omicron is a weakened version of the original COVID.

While T cells can’t stop disease, they blunt its impact, often making it appear more mild than it might in a population with virtually no immunity—like China before the lifting of “zero COVID” measures. “Omicron can cause severe disease,” Agrawal said. “It is not nature’s vaccine. ).

Antibody escape, the risk of serotype formation, and rapid immune waning: modeling the implications of SARS-CoV-2 immune evasion (In the long-term, invading variants that induce weak cross-immunity against pre-existing strains may co-circulate with those pre-existing strains.

Less durable immunity does not drive positive selection as a trait, but such strains may transmit at high levels if they establish. Overall, our results draw attention to the importance of inter-strain cross-immunity as a driver of transmission trends and the importance of early immune evasion data to predict the trajectory of the pandemic.). medRxiv. 25.1.2023.

Weekly screening tests also have a positive impact on disease mitigation. While self-quarantining symptomatic infections and school closures are effective measures for decreasing semester-end infections, they increase absenteeism. The model assesses different nonpharmaceutical interventions applied to K-12 schools during the pandemic and estimates their impact on COVID-19 under varying assumptions. The results are presented using parameter estimates associated with the Omicron variant, but the model is general and can be applied to different parameters. In addition, although we specify our targeted population group as K-12 schools, the conceptual model can be easily extended to implement other population groups (e.g., nursing homes or prisons) if we have a good quantitative understanding of their social contact patterns.).

Endemicity Is Not a Victory: The Unmitigated Downside Risks of Widespread SARS-CoV-2 Transmission (Our findings suggest large increases in virulence for SARS-CoV-2 would result in minimal loss of transmissibility, implying that the IFR may vary freely under neutral evolutionary drift. We use an SEIRS model framework to examine the effect of hypothetical changes in the IFR on steady-state death tolls under COVID-19 endemicity. Our modeling suggests that endemic SARS-CoV-2 implies vast transmission resulting in yearly US COVID-19 death tolls numbering in the hundreds of thousands under many plausible scenarios, with even modest increases in the IFR leading to unsustainable mortality burdens. Our findings highlight the importance of enacting a concerted strategy and continued development of biomedical interventions to suppress SARS-CoV-2 transmission and slow its evolution.).

Internal emails from FOI’s question the integrity of the Swedish strategy (It’s difficult to know the extent to which one country influenced another, perhaps some found the confirmation bias they were looking for in those with similar strategy ideas. We do know that representatives of other countries, for example Sweden’s Anders Tegnell lobbied other countries to adopt his strategy throughout the pandemic, even meeting with the UK Government later in 2020. Tegnell had come under criticism early on after emails showed the epidemiologist in charge of Sweden’s strategy appearing to ask whether a higher death rate among older people might be acceptable if it led to faster herd immunity. Tegnell insists the Swedish objective was not to achieve herd immunity but rather to slow the spread of covid enough for health services to cope, however its emerged through freedom of information requests that Tegnell had deleted some of his official emails leaving gaps in the evidence trail. Lobbing for mass infection: While Swedish authorities claim they weren’t actively pursuing herd immunity, it doesn’t appear that way when looking at some of Tegnell and his colleagues lobbying in other countries during 2020).

Neurological and psychiatric risk trajectories after SARS-CoV-2 infection: an analysis of 2-year retrospective cohort studies including 1 284 437 patients (Risks of the common psychiatric disorders returned to baseline after 1–2 months (mood disorders at 43 days, anxiety disorders at 58 days) and subsequently reached an equal overall incidence to the matched comparison group (mood disorders at 457 days, anxiety disorders at 417 days). By contrast, risks of cognitive deficit (known as brain fog), dementia, psychotic disorders, and epilepsy or seizures were still increased at the end of the 2-year follow-up period. Post-COVID-19 risk trajectories differed in children compared with adults: in the 6 months after SARS-CoV-2 infection, children were not at an increased risk of mood (HR 1·02 [95% CI 0·94–1·10) or anxiety (1·00 [0·94–1·06]) disorders, but did have an increased risk of cognitive deficit, insomnia, intracranial haemorrhage, ischaemic stroke, nerve, nerve root, and plexus disorders, psychotic disorders, and epilepsy or seizures (HRs ranging from 1·20 [1·09–1·33] to 2·16 [1·46–3·19]). Unlike adults, cognitive deficit in children had a finite risk horizon (75 days) and a finite time to equal incidence (491 days). A sizeable proportion of older adults who received a neurological or psychiatric diagnosis, in either cohort, subsequently died, especially those diagnosed with dementia or epilepsy or seizures. Risk profiles were similar just before versus just after the emergence of the alpha variant (n=47 675 in each cohort). Just after (vs just before) the emergence of the delta variant (n=44 835 in each cohort), increased risks of ischaemic stroke, epilepsy or seizures, cognitive deficit, insomnia, and anxiety disorders were observed, compounded by an increased death rate.

Cholera, Key facts:
Most of those infected will have no or mild symptoms and can be successfully treated with oral rehydration solution.
A global strategy on cholera control, Ending Cholera: a global roadmap to 2030, with a target to reduce cholera deaths by 90% was launched in 2017.
Researchers have estimated that each year there are 1.3 to 4.0 million cases of cholera, and 21 000 to 143 000 deaths worldwide due to cholera (1)
Cholera is an acute diarrhoeal disease that can kill within hours if left untreated.
Provision of safe water and sanitation is critical to prevent and control the transmission of cholera and other waterborne diseases.
Severe cases will need rapid treatment with intravenous fluids and antibiotics.
Oral cholera vaccines should be used in conjunction with improvements in water and sanitation to control cholera outbreaks and for prevention in areas known to be high risk for cholera. WHO. 30.3.2022.

Assessing the impact of SARS-CoV-2 prevention measures in Austrian schools using agent-based simulations and cluster tracing data (In conclusion, we find that different types of schools require different combinations of preventive measures. The ideal mix of mitigation measures needs to be more stringent in secondary schools than in primary schools, and needs to preferentially focus on teachers as sources of infection. Even under strict prevention measures, larger clusters in schools will still occur at regular intervals when the incidence in the general population is high enough. However, in this work we have shown that when keeping schools open during the COVID-19 pandemic a calculable risk can be achieved by a combination of stringently enforced measures which can be successively relaxed as larger portions of the population become vaccinated.). nature communications. 27.1.2022.

The Effectiveness Of Government Masking Mandates On COVID-19 County-Level Case Incidence Across The United States, 2020 (…observational study of matched cohorts from 412 US counties between March 21 and October 20, 2020, we estimated the association between county-level public masking mandates and daily COVID-19 case incidence. On average, the daily case incidence per 100,000 people in masked counties compared with unmasked counties declined by 25 percent at four weeks, 35 percent at six weeks, and 18 percent across six weeks postintervention. The beneficial effect varied across regions of different population densities and political leanings. The most concentrated effects of masking mandates were seen in urban counties; the benefit of the mandates was potentially stronger within Republican-leaning counties. Although benefits were not equally distributed in all regions, masking mandates conferred benefit in reducing community case incidence during an early period of the COVID-19 pandemic.).

Schools in communities with substantial levels of community spread will need to be more vigilant to ensure adherence of mitigation strategies to minimize transmission. Our results show that for school administrators, teachers, and parents to provide the safest environment, it is important to utilize multiple mitigation strategies and contract tracing that reduce SARS CoV-2 transmission by at least 69%. This will require training, reinforcement, and vigilance to ensure that the highest level of adherence is maintained over the entire school term.). Journal of Public Health Management and Practice.

Fyysikot toivat kuitenkin jo pandemian alkuvaiheessa esille, että korona leviää voimakkaimmin nimenomaan hengitysilmassa.

Impacts of K-12 school reopening on the COVID-19 epidemic in Indiana, USA (There is now a growing body of evidence that school closures contributed to mitigating the first wave of the epidemic  and, as we have shown, may have contributed to the resurgence of SARS-CoV-2 during fall 2020. Our study adds to this evidence, and suggests an even greater impact of school reopening than several other studies. This is due in part to our assumption that asymptomatic and symptomatic infections contribute similarly to transmission, and in part to our model’s ability to capture chains of transmission within schools and extending out into the community. Our study echoes several modeling studies in emphasizing the importance of reducing school operating capacity to impede transmission. As schools grapple with COVID-19 going forward, results such as these provide an important basis for motivating the adoption and sustainment of reduced school operating capacity and adherence to face-mask requirements in schools. As we demonstrated, these actions are highly consequential for those directly linked to schools and for the communities in which they are embedded.). Epidemics. December. 2021.

Koronavirus leviää ilmateitse – onko sillä merkitystä?
On hämmästyttävää, miten vähän on varmaa tietoa siitä, millä lailla yleiset ylähengitysteiden tartuntataudit tarttuvat. Lyhyessä ajassa on käynyt selväksi, että aiemmin tunnettujen kosketus- ja pisaratartuntamekanismien lisäksi aerosolivälitteinen leviäminen on yleistä (1,2). Usein näiden reittien erottaminen ei ole helppoa. Infektoitunut voi tartuttaa vieressä seisovan terveen henkilön kaikilla kolmella tavalla. Kaukana tartunnan saaneesta olevat eivät voi saada tartuntatautia kosketus- tai pisaratartuntana – jäljelle jää siis aerosolitartunta.Lääkärilehti. 3.12.2021.

Impact of community masking on COVID-19: A cluster-randomized trial in Bangladesh (Even in places where it is obligatory, people tend to optimistically overstate their compliance for mask wearing. How then can we persuade more of the population at large to act for the greater good? Abaluck et al. undertook a large, cluster-randomized trial in Bangladesh involving hundreds of thousands of people (although mostly men) over a 2-month period. Colored masks of various construction were handed out free of charge, accompanied by a range of mask-wearing promotional activities inspired by marketing research. Using a grassroots network of volunteers to help conduct the study and gather data, the authors discovered that mask wearing averaged 13.3% in villages where no interventions took place but increased to 42.3% in villages where in-person interventions were introduced. Villages where in-person reinforcement of mask wearing occurred also showed a reduction in reporting COVID-like illness, particularly in high-risk individuals. ). Science. 2.12.2021.

Aikuisista yli 99 % täysrokotettuja, mutta korona ryöpsähti silti – Gibraltarin tapaus ihmetyttää, mutta nyt ”tehosterokote todella toimii”. Pienen Gibraltarin koronatilanne nousee tällä hetkellä toistuvasti esiin rokotekeskusteluissa, koska maa on täysin rokotettu mutta tartunnat lähtivät silti eksponentiaaliseen kasvuun. Mediuutiset. 2.12.2021.

Tässä on THL:n uusi suositus – kaikki 3. rokotukseen: ”Varastossa 1,5 miljoonaa annosta”. (THL suosittelee kolmansia koronarokoteannoksia tarjottavaksi kaikille 18 vuotta täyttäneille 5–6 kuukautta toisen annoksen jälkeen. Tehosteannoksia suositellaan otettavaksi niin ikään 5–6 kuukautta toisen rokoteannoksen jälkeen niille ryhmille, joille THL on jo aiemmin suositellut kolmatta rokoteannosta. Voimakkaasti immuunipuutteisille kolmatta annosta suositellaan otettavaksi jo kaksi kuukautta toisen annoksen jälkeen.

– Suosituksen perusteena on koronavirusinfektioiden määrän vähentäminen ja tartuntojen leviämisen estäminen. Kolmas rokoteannos vähentää viruksen kiertoa väestössä ja parantaa suojaa vakavaa tautimuotoa vastaan, sanoo THL:n ylilääkäri Hanna Nohynek tiedotteessa.

– [Mia] Kontio lisää, että toisen annoksen osalta rokotekattavuus laahaa pahasti perässä. Tulevaisuudessa ei Kontion mukaan välttämättä kuitenkaan tarvita useita rokotuskierroksia, ainakaan perusterveiden kohdalla.). Iltalehti. 2.12.2021.

Omicron will likely ‘dominate and overwhelm’ the world in 3-6 months, doctor says. “Frankly, omicron will dominate and overwhelm the whole world in three to six months,” Singapore doctor Leong Hoe Nam told CNBC’s “Street Signs Asia.”
New vaccines targeting omicron are a “nice idea” but won’t be practical because of the transmissibility of the strain, he said.
Experts don’t know exactly how contagious the highly mutated omicron variant is, but the virus’ spike protein — which binds to human cells — has mutations associated with higher transmission and a decrease in antibody protection. CNBC. 2.12.2021.

Omicron variant found in two previous test samples. RIVM has found the Omicron variant in test samples taken in the Netherlands earlier in November.

COVID-19: Why the Omicron variant has scientists worried.
Scientists have detected cases of a new variant of SARS-CoV-2, which is the virus that causes COVID-19, in a number of countries. Omicron (B.1.1.529) has an unprecedentedly large number of mutations in the part of its genome that encodes a key section of its spike protein, which the virus uses to infect host cells. This suggests that Omicron may be able to evade some of the immune protection afforded by vaccines, many of which are based on the original spike protein, and past infections.

(Ministeriö salaa koronapäätösten taustalla käydyn sähköpostikirjeenvaihdon, vaikka lain mukaan näin merkittävän viestinvaihdon kuuluisi olla julkista, kirjoittavat Mari Julku ja Sami Koski.  Pitkin koronataivalta on ihmetelty erityisesti perhe- ja peruspalveluministeri Krista Kiurun (sd) suurta valtaa rajoituspäätöksissä. Lukuisissa analyyseissä on kerrottu, kuinka Kiurun tahto tiukemmista rajoituksista on aina jyrännyt lievemmät näkökannat. Syyskuun viimeisenä päivänä tähän tuli muutos, kun ravintolarajoituksia lievennettiin reippaasti täysin yllättäen. Ilta-Sanomien mukaan pääministeri Sanna Marin (sd) oli alkanut ajaa ravintolarajoitusten purkua vasten Kiurun tahtoa. IS:n mukaan Kiuru on nyt ”yksin kuin haavoitettu eläin”. Hänen tukenaan on enää sosiaali- ja terveysministeriön (STM) niin kutsuttu ”nuiva kolmikko”. Siihen kuuluvat Iltalehdenkin sivuilla usein esiintyneet osastopäällikkö Taneli Puumalainen, strategiajohtaja Liisa-Maria Voipio-Pulkki ja kansliapäällikkö Kirsi Varhila. Mutta minkälaista valtaa Kiuru on todella käyttänyt? Onko esimerkiksi THL:n mielipiteitä ohitettu? Vai ovatko Kiuru ja Varhila olleet samoilla linjoilla koronarajoitusten purkamisesta kuin esimerkiksi THL:n johtohahmot Markku Tervahauta ja Mika Salminen? Torstaina STM ja THL arvioivat, että rajoituksia purettiin liian aikaisin. Pääministeri Marin ei kuitenkaan allekirjoittanut näkemystä. Toisaalta esimerkiksi THL oli kuukautta aiemmin aivan toista mieltä. Sen mukaan rajoituksia olisi voitu purkaa asteittain jo syyskuun alussa. ). Iltalehti 9.10.2023.

Dose-dependent COVID-19 symptoms. (COVID-19 presentation varies widely between individuals, ranging from asymptomatic to life-threatening infection. Several host and viral factors have been shown to influence disease penetrance and severity. In addition, the infectious dose has also been speculated to have a role. Dabisch et al. show in a SARS-CoV-2 challenge study of 16 cynomolgus macaques that the infectious dose indeed influences symptom development and seroconversion. They used aerosolized virus at different concentrations and found that low doses could lead to seroconversion and virus replication in the respiratory tract without symptom development, such as fever, whereas higher doses produced fever, which suggest that low infectious doses might be associated with asymptomatic infection.)nature reviews microbiology. 7.9.2021.

To summarize, our results highlight that (1) when is moderately high, all the hybrid telecommuting strategies considered reduce it to less than 1, and the choice between them should primarily be done on the basis of practical considerations. (2) To help prevent dissemination of the disease, it is preferable to alternate over longer periods (weekly rather than daily), but the difference is so slight that practical, psychological, and other considerations should determine the alternation time.

Evidence for Biological Age Acceleration and Telomere Shortening in COVID-19 Survivors (The results show a consistent biological age increase in the post-COVID-19 population, determining a DeltaAge acceleration of 10.45 ± 7.29 years (+5.25 years above the range of normality) compared with 3.68 ± 8.17 years for the COVID-19-free population (p < 0.0001). A significant telomere shortening parallels this finding in the post-COVID-19 cohort compared with COVID-19-free subjects (p < 0.0001). Additionally, ACE2 expression was decreased in post-COVID-19 patients, compared with the COVID-19-free population, while DPP-4 did not change. In light of these observations, we hypothesize that some epigenetic alterations are associated with the post-COVID-19 condition, particularly in younger patients (< 60 years).).

COVID-19 Indoor Safety Guideline.

Risk of rapid evolutionary escape from biomedical interventions targeting SARS-CoV-2 spike protein (Our modeling suggests that SARS-CoV-2 mutants with one or two mildly deleterious mutations are expected to exist in high numbers due to neutral genetic variation, and consequently resistance to vaccines or other prophylactics that rely on one or two antibodies for protection can develop quickly -and repeatedly- under positive selection. Predicted resistance timelines are comparable to those of the decay kinetics of nAbs raised against vaccinal or natural antigens, raising a second potential mechanism for loss of immunity in the population. Strategies for viral elimination should therefore be diversified across molecular targets and therapeutic modalities). PLOS ONE. 28.4.2021.

COVID-19 in context: Why do people die in emergencies? It’s probably not because of collective psychology (Notions of psychological frailty have been at the forefront of debates around the public response to the COVID-19 pandemic. In particular, there is the argument that collective selfishness, thoughtless behaviour, and over-reaction would make the effects of COVID-19 much worse. The same kinds of claims have been made in relation to other kinds of emergencies, such as fires, earthquakes, and sinking ships. We argue that in these cases as well as in the case of the COVID-19 pandemic, other factors are better explanations for fatalities – namely under-reaction to threat, systemic or structural factors, and mismanagement. Psychologizing disasters serves to distract from the real causes and thus from who might be held responsible. Far from being the problem, collective behaviour in emergencies – including the solidarity and cooperation so commonly witnessed among survivors – is the solution, one that should be harnessed more effectively in policy and practice.).
