There’s no way you’d want to go to work when you’ve got the telltale signs of gastro: nausea, abdominal cramps, vomiting and diarrhoea. But what about when you’re feeling a bit better? When is it safe to be around colleagues, or send your kids to school or daycare?

The health department recommends staying home from work or school for a minimum of 24 hours after you last vomited or had diarrhoea. But the question of how long someone is contagious after recovering from gastro is a very different question.
