My two year old had a very high temperature on Monday and a couple of pinprick red dots on the inside of his lips. By Tuesday he had the rash/blisters around his mouth. It is now day 5 and he is still developing more blisters and red spots on hands/feet/face and now all over his legs. From reading online the spots should be settling down by now and starting to improve. Can this be normal for more to develop from day 5 onwards? Also is it very likely that we (parents) and sibling will develop hfm? When would we typically start developing symptoms if we were to catch it? Thanks!
