We've got another vomiting bug passing through the family atm - DS 2 brought it home from school where it's doing the rounds.
We seem to get one a year at least - last came via some friends we went to visit - my friend revealed after lunch (which she'd cooked) that she'd just recovered (as in yesterday) from a D&V bug, and 2 days later we all came down with it on holiday, which was fun.
Anyway, my DM says there weren't bugs like this going round in the 70s when I was little. She might be wrong, so wondering what other people's experience is? Are there more of this type of bug now and why would that be?
