For my kids, contagious diseases come from the doctor's office. (there is a concentration of sick people) The most horrifying disease was hand/foot/mouth disease, which really should be called hand/foot/mouth/anus disease but that would be rude. It can cause paralysis. There is no vaccine. My kids got huge blisters, including one that fully covered the end of a thumb.

So, bear in mind, that doctor visit carries some risk and could even cause permanent damage.
