The team estimated that under-20s are at half the risk of Covid-19 infection than over-20s. They also found a wide variation in symptomatic cases linked to age: only 21 percent of those aged 10 to 19 were likely to show symptoms compared with 69 percent of over-70s. NOT A COMPLICATED QUESTION"Whether to reopen schools or not is a complicated question," said study co-author Rosalind Eggo. Numerous studies have shown that Covid-19 symptoms are likely to be more severe the older the patient is. "We were not able to estimate exactly how infectious asymptomatic cases more generally are compared to symptomatic cases," said Nicholas Davies.
