Schools do not spread Covid-19, multiple studies find

The rise in Covid-19 cases following the reopening of schools in September is probably just a coincidence of timing, four new research papers suggest.

The studies “cast doubt on the role of schools in spreading the coronavirus” and indicate that “a renewal of widespread school closures would have a limited effect on curbing Sars-Cov-2, the virus that causes Covid-19”, says the Financial Times.

Previous analysis of raw data from across Europe has painted a confusing and contradictory picture of the potential link between schools and the spread of the coronavirus.

A total of 52 countries, “including France and Spain, actually saw infection rates rise during the holidays”, according to The Telegraph. “Some, such as Croatia, have seen cases fall after reopening schools. Others, like Hungary and Great Britain, have seen a rise.”

However, newly published reports have found no evidence that schools have any significant impact on infection rates. The latest evidence comprises:

• a study conducted by the Norwegian National Institute of Public Health which found that infection rarely spreads from child to child, and that “the most common route of transmission to children and pupils is from adults in their household” 
• a report from Germany’s Institute of Labor Economics, which says that “school re-openings in Germany under strict hygiene measures combined with quarantine and containment measures have not increased the number of newly confirmed Sars-CoV-2 infections”
• two reviews of data from countries across the world, conducted by the World Health Organization and the European Centre for Disease Prevention and Control, which both “concluded that most children do not develop symptoms and there is little evidence of transmission in schools”, says the FT.

Nevertheless, says The Guardian, “more than 400,000 children in England were off school last week for coronavirus-related reasons”, and some schools have been forced to close.

Wales and Scotland have also been wrestling with the problem of outbreaks in schools.

The Welsh government has announced that older pupils will not return to classes during the country’s two-week “firebreak” lockdown, which begins on Friday. But “Scottish First Minister Nicola Sturgeon has pledged to do everything in her power to keep schools open” north of the border, the BBC reports.
