HFMD is a illness that is normally affecting children. I can tell if my friend might have HFMD if he has fever or ulcers. It affects many children other than children under 5. I know as if it only affects children under 5, the school will not be warning me and other students about HFMD. The main thing needed to prevent HFMD is to keep myself clean, like washing hands frequently. I do not know of anone who has gotten HFMD. People who has HFMD should not go to school/work. I would advise children to keep thenself clean.
