I just wondered if there are any health professionals on here. We are due to meet up with a relative this weekend whose daughter is on her 2nd dose of antibiotics for tonsillitis in 2 weeks. Is it right that she is not contagious after 24 hours of antibiotics? I have a toddler and am trying not to buy into any hysteria but having spent a lot of time with him in hospital last year, I don't want to run any risks.
