DS came down with Hand Foot and Mouth on Friday, confirmed by GP. DH and I had bad throats but otherwise ok, now today I suddenly have chills and aches (unsure if it's related but probably?). We're due to go on Saturday and I need to cancel the booking very soon if we won't go. My family would be very disappointed, but I don't want to make them ill and they can be a bit cavalier about infections. I feel like I'm being unreasonable whether we go or not because the timeline makes us "maybe" contagious. What do you think? I've asked some of them for their opinion and just had it shrugged off.
