Adults who lived with children during the pandemic’s second wave were only slightly more at risk of Covid-19 than those who lived without them, suggesting school attendance has minimal impact on infection rates, a new study has found.
While there was a small increased risk of infection and hospitalisation for those aged 65 and under who lived with school-aged children between September and December last year, they were no more likely to be admitted to intensive care or die than those who lived without children.
The peer-reviewed study, published in the British Medical Journal, found no evidence of a noticeably increased risk of infection during the first wave in the UK between February and August, compared to those adults who do not live with children.

- Environmental effects
Texas Gov. Greg Abbott announced last week that his state is ending its mask mandate and business capacity limits. While Democrats and many public-health officials denounced the move, ample data now exist to demonstrate that the benefits of stringent measures aren’t worth the costs.
…We have since learned that the virus never spreads exponentially for very long, even without stringent restrictions. The epidemic always recedes well before herd immunity has been reached.
Some 8.8 million schoolchildren in the UK have experienced severe disruption to their education, with prolonged school closures and national exams cancelled for two consecutive years. School closures have been implemented internationally1 with insufficient evidence for their role in minimising covid-19 transmission and insufficient consideration of the harms to children.
Most people infected with SARS-CoV-2 are contagious for 4–8 days.7 Specimens are generally not found to contain culture-positive (potentially contagious) virus beyond day 9 after the onset of symptoms, with most transmission occurring before day 5. This timing fits with the observed patterns of virus transmission (usually 2 days before to 5 days after symptom onset), which led public health agencies to recommend a 10-day isolation period. The short window of transmissibility contrasts with a median 22–33 days of PCR positivity (longer with severe infections and somewhat shorter among asymptomatic individuals). This suggests that 50–75% of the time an individual is PCR positive, they are likely to be post-infectious.
Immunocompetent staff, patients and residents who have tested positive for SARS-CoV-2 by PCR should be exempt from routine re-testing by PCR or LFD antigen tests (for example, repeated whole setting screening or screening prior to hospital discharge) within a period of 90 days from their initial illness onset or test (if asymptomatic) unless they develop new COVID-19 symptoms. This is because fragments of inactive virus can be persistently detected by PCR in respiratory tract samples following infection – long after a person has completed their isolation period and is no longer infectious.
Analysis of the age profile of Covid infections, however, does not point to schools being especially important in the early-stage growth of the second wave. Although the report does also observe that ‘school closures can contribute to a reduction in SARS-CoV-2 transmission’.
But had schools played a big role you would expect to have seen a sharp increase in cases among children of school age a week or two following the return to the classroom. Instead, the ECDC noted that Europe’s second wave began with a sharp increase in cases among 19 to 39 year olds in mid August. Cases among 16 to 18 year olds also increased around this time, but the curve of infections among younger children rose much more gradually, in step with infection rates in the over-40s.
The return to school of children around mid-August 2020 coincided with a general relaxation of other NPI measures in many countries and does not appear to have been a driving force in the upsurge in cases observed in many EU Member States from October 2020.
The low seroprevalence of SARS-CoV-2 antibodies in young children in this study may indicate that they do not play a key role in SARS-CoV-2 spreading during the current pandemic.
- German researchers enrolled nearly 2,500 parents and their children in a study
- Found three times as many adults had coronavirus antibodies than children
- Data also shows a previously infected adult and an uninfected child was 4.3 times more common than a previously infected child and an uninfected parent
Children are unlikely to have played a significant role in the spread of coronavirus during the first wave last year, a study shows.
Throughout the pandemic it has become increasingly evident children are less affected by Covid-19; symptoms, severe disease and death figures in children are all much lower than would be expected when compared to the rest of the population.
Figures from Public Health England (PHE) show the current risk of dying from coronavirus if infected is 1,513 per 100,000 people for over-80s, but for children aged five to nine, this is just 0.1 per 100,000.
Ivor Cummins aka the Fat Emperor – gives James the lowdown on why you can’t trust anything our governments tell us about Covid-19. If you want the facts on Coronavirus – how deadly is it? do lockdowns and masks work? how does it compare with previous pandemics? – you’ve come to the right place

The unprecedented measures of universal lockdowns, tight institutional lockdowns of care homes, universal masking of the general population, obsession with surfaces and hands, and the accelerated vaccine deployment are contrary to known science, and contrary to recent leading studies. There has been government recklessness by action and negligence by omission. Institutional measures have been needed for a long time to stem corruption in both medicine and public health policy.
Conclusions and Relevance In this cohort study, there was no evidence of placental infection or definitive vertical transmission of SARS-CoV-2. Transplacental transfer of anti-SARS-CoV-2 antibodies was inefficient. Lack of viremia and reduced coexpression and colocalization of placental angiotensin-converting enzyme 2 and transmembrane serine protease 2 may serve as protective mechanisms against vertical transmission.
More than 10,000 people acquired coronavirus when they were being treated in hospital for other illnesses, The Telegraph can disclose.
Hampshire Hospitals NHS Foundation Trust said that 139 out of 357 Covid-19 patients they had treated had caught the virus there – 38.9 per cent – with board papers showing that five patients had died.
- Blood samples unveiled this week show people in California, Oregon and Washington infected in December
- Further tests on blood taken in mid-to-late December and into early January found virus in six more states
- Italy, Brazil and France have all since found traces of the virus before China even acknowledged it existed
- Evidence has emerged in Spain and the UK suggesting that Covid-19 was around before testing was possible
- Claims the virus emerged in a market in Wuhan last winter have crumbled in the face of scientific evidence
We do not identify a single recurrent mutation in this set convincingly associated with increased viral transmission. Instead, recurrent mutations currently in circulation appear to be evolutionary neutral and primarily induced by the human immune system via RNA editing, rather than being signatures of adaptation. At this stage we find no evidence for significantly more transmissible lineages of SARS-CoV-2 due to recurrent mutations.
Stringent COVID-19 control measures were imposed in Wuhan between January 23 and April 8, 2020. Estimates of the prevalence of infection following the release of restrictions could inform post-lockdown pandemic management. Here, we describe a city-wide SARS-CoV-2 nucleic acid screening programme between May 14 and June 1, 2020 in Wuhan. All city residents aged six years or older were eligible and 9,899,828 (92.9%) participated. No new symptomatic cases and 300 asymptomatic cases (detection rate 0.303/10,000, 95% CI 0.270–0.339/10,000) were identified. There were no positive tests amongst 1,174 close contacts of asymptomatic cases. 107 of 34,424 previously recovered COVID-19 patients tested positive again (re-positive rate 0.31%, 95% CI 0.423–0.574%). The prevalence of SARS-CoV-2 infection in Wuhan was therefore very low five to eight weeks after the end of lockdown.
The recommendation to wear surgical masks to supplement other public health measures did not reduce the SARS-CoV-2 infection rate among wearers by more than 50% in a community with modest infection rates, some degree of social distancing, and uncommon general mask use. The data were compatible with lesser degrees of self-protection.
