Schools reopening after coronavirus outbreak: What’s the risk?
CNNLondon CNN — Moves by countries to reopen schools that were shut to prevent the spread of coronavirus could risk a second wave of infections, some studies suggest. Most cases of Covid-19 in children are mild, but studies suggest kids may play a major role in transmitting the virus to each other and to vulnerable adults – and that keeping schools closed for longer may help stop the spread of the coronavirus. They estimated that removing all interactions normally seen in schools for children up to 14 years old would lead to a reduction in the average daily number of new cases of about 42%, while reducing children’s interactions to those typically seen during vacation periods could reduce new cases by 64%. “At this stage, when we just don’t know enough about the susceptibility of children to picking up the virus and transmitting it, then we should err on the side of caution.” Countries including China, Taiwan, Denmark and Israel have reopened schools and others are considering doing the same. He said it was also important to think about how children interact – “what the family units look like, how many vulnerable people are within those family units, and that I imagine will change slightly from country to country in terms of intergenerational households and especially for example, amongst certain ethnic minority groups.” Clarke warned that when schools closed for the summer during the swine flu epidemic in 2009, “normal cases dropped like a stone, and then went racing back up again in sort of mid-September.” “It takes a few weeks for these things to get going,” he added.
