Logged off early yesterday but just wanted to mention re schools : France is bringing us back into work with classes of 15, so somewhere there’s science saying 15 is acceptable.
There was a cluster in a French lycée (high school) in l’Oise, near Paris. They’ve made quite an interesting study of it. 41% of the school population (students, teachers and non-teaching staff) tested positive for Covid. In total 661 people tested positive as they also tested the “second line”, the households of everyone at the school. When they later performed blood tests for antibodies they got positive results for 171 people (25,9%). This worked out to 41% of infected first line, and 10,9% of infected second line. So the second line were less likely to have to have produced antibodies. Research into why is ongoing. The theory at the moment is that, much like in hospitals, those infected at school were exposed to multiple sources, while at home is was just the one student bringing it home and infecting the family.
In terms of infection, 38,3% of the students were positive, 43,4% of teaching staff and 59,3% of non-teaching staff.
Almost 88% of the people infected in the lycée cluster reported loss of sense of smell or sense of taste. 17% had no symptoms. 5,3% were hospitalised. The average age of those hospitalised was 49 years, average age of those not hospitalised was 18. It affected 7,2% of smokers and 28% of non-smokers.
There are all sorts of other statistics coming out from it. It’s fascinating as it’s a known, young population.
