KEEPING windows open is more effective at reducing the spread of Covid than masks for primary-age kids, a government scientist has said.
Professor Calum Semple, a member of the Scientific Advisory Group for Emergencies (Sage), told BBC Radio 4’s Today programme that he is “not a fan” of asking young children to wear masks, and there are better strategies for managing the virus.
He said: “If I had to invest in a single activity to improve the environment both for the children and the adults, I’d be looking at improving the ventilation, unsealing windows that have been painted shut and kept shut for energy-saving reasons … improving air exchanges.
“That would be a much more effective way to reduce transmission in schools.”
He added: “Primary school children are the lowest risk both to themselves and to society.
“There is really good data coming out … that shows that children are half as likely to acquire the virus to a third as likely to acquire the virus.
“When it comes to transmitting, they are probably half as likely to transmit it as adults.
