Stockholm, Aug 16 (IANS): A group of 26 Swedish researchers suggested that children should wear face masks in schools to prevent the spread of the coronavirus, it was reported.

"The Swedish Public Health Agency makes the wrong assessment of children's infectivity," Xinhua news agency quoted the researchers, who are members of the Swedish Science Forum COVID-19, as saying in an article on Saturda.

According to the researchers, there is now data from South Korea, the US and Israel that proves that the children are contagious -- and data from Sweden that proves that the children can become seriously ill.

They also reasoned about the fact that the Swedish cases of infection have decreased since the schools closed, and believed that the concern about an increased spread of infection before the start of school, which happens next week, is justified.

"Because children are contagious, can become seriously ill, and it is unclear today how a mild infection also affects their future health, we should already at the start of school take measures to keep the infection down," they wrote.

The researchers suggested, among other things, that face masks should be worn in schools, that sports should be held outdoors, that meals should be eaten class by class and that group teaching avoided. They also suggested that children in families where someone belongs to a risk group should be allowed to receive home schooling -- and urge parents to provide their children with face masks regardless of (authority's) recommendations.

"It is now, when infection rates are relatively low, that we have a second chance to take control of the epidemic," they wrote.

Last week, Ole Petter Ottersen, president of the Swedish medical university Karolinska Institutet, advocated the use of face masks on the university campus if it's difficult to maintain physical distance before the term start.

"We also recommend the use of face masks in situations where physical distancing may be difficult or impossible to observe. In doing so, we take the stand that the effectiveness of face masks can no longer be disputed."

Sweden has so far reported 5,783 deaths and 84,294 cases.

It has neither imposed a lockdown -- even during the peak of the pandemic -- nor asked people to wear face masks in public, quoting a lack of support in research.

On its website, the Swedish Public Health Agency, which offers national guidance for the pandemic, writes that the current state of knowledge shows that few children and young people are infected with Covid-19 -- and that school activities have not been shown to be a driving force in the spread of infection.
