Monday

Children in New York have been back at school for a single week without masks and already the old favourites are back. On Saturday, it’s a sore throat and a sniffle (two at-home tests, not Covid). On Sunday, the phlegmy cough sets in (another test, not Covid). On Monday, the vomiting starts, something we haven’t seen since 2019. Hello, old friend.
