The student here hasn't been tested positive yet, so they've not shut the school. The school in France has shut, but one of the kids there was actually infected, so it's not the same.In France they're fully disinfecting apartment, and the local school (where one of the infected kids who lived there intended just once for 1/2 a day since being infected) has been shut until kids he came into contact with (just 5 allegedly) are first tested..... Seems about right.
Whereas here, in the Grenadier pub, the staff are told to self isolate, there's nothing published about any form of disinfecting and the student from Portslade school also told to self isolate, it's quoted that the school asked if it should close (as the boy had been there) and the response from public health UK is "there's no need at this time"
So they're gambling there's no trace of infection in pub and school boy hasn't got it and passed it on. The french are not simply gambling and taking every precaution.
The pub is a different matter, and maybe that should be closed, but that's a private business, so the decision making isn't the same as a school.
