Currently, the main preventive medicine against HFMD is the inactivated EV71 vaccine. In addition, HFMD can be prevented by paying attention to hygiene and so on. HFMD is mainly caused by infections of intestinal viruses such as coxsackievirus and enterovirus 71 (EV71). Currently, the inactivated EV71 vaccine is the main drug used to prevent HFMD. However, it can only prevent HFMD caused by EV71, and cannot prevent HFMD caused by other enteroviruses. HFMD can also be prevented by paying attention to environmental hygiene. During epidemics, minimize visits to public places where people gather and the air is not well ventilated. If you feel unwell, it is recommended that you should seek medical advice and treatment promptly.
