Due to go away with my kids, and my friend, her partner and 4 kids tomorrow. Her partner has developed whooping cough this week, started antibiotics on Thurs. NHS say you are not contagious after 48 hours of antibiotics, although other countries state that it takes 5 days. Both my kids have health conditions which make them more vulnerable to respiratory complications (which you can get with whooping cough). Even if her partner is not contagious after 48 hours, I figure the other 5 members of her family on the holiday could come down with it while we’re there. Not sure whether reasonable to cancel, or if I should arrive two days later (accommodation booked until Weds) when the partner may be less contagious… or would you just go anyway?
