premise: well my whole family basically has Fifth disease which is a virus that most of the time gotten by children and symptoms are hive like rash and fever . In adults if not in absolute health they get joint pain and nausea . So apparently I might have had it but the hives part and no fever or joint pain that I recall . yesterday Makishi ( my little brother ) had this hives thing and fever so mom took him to children 's ER around 3 - 4 so then now my mom has it with the joint pain and nausea she was like freakin ' dying ! How might the entire family com to have the Fifth disease ?
hypothesis: The entirety of the family must have gotten it somewhere independently .
