Most children with HFMD will get better 1-2 weeks after the onset of the disease. First of all, in the common type of HFMD, children only have herpes on their hands, feet and mouth, and their mental state and appetite for food are good. Most of them will get better in about 1 week after applying Chinese medicine for clearing fever and detoxifying the toxin, and drinking warm water and other symptomatic supportive treatment appropriately. Secondly, if HFMD is serious or even critical, mainly caused by EV71 enterovirus, children will have high fever that does not subside, and even complications such as encephalitis and myocarditis, and the course of the disease in children at this time is mostly about 2 weeks.
