Perhaps it is schoolchildren who remain the key distributors of the coronavirus in Europe.
Asymptomatic cases coronavirus in schools, colleges and universities can be a key link in the rapid spread of the virus. Up to 70% of children attending school can be infected with the virus, i.e. are carriers.
According to Professor Martin Hibberd of the London School of Hygiene and Tropical Medicine, asymptomatic patients with from the very beginning of the pandemic, they have been a huge problem for governments seeking to bring the virus under the control. Scientists agree that 30% to 40% of adults show no symptoms on the day of testing, even if they have already become infected.
For schoolchildren, this indicator should be even higher, in secondary school, I think, 50% of students are infected, and in primary school - up to 70%. They have caught the virus, but they do not feel it.It is not yet clear how strong the spread of schoolchildren without symptoms of COVID-19 is, data on how much of the virus is shed by asymptomatic carriers is still conflicting.
But in the UK they are already thinking about mass testing of schoolchildren: even if it does not work out identify all carriers, those who have more virus in their blood, tests will be able to determine quite accurately and promptly.
