Parents need to monitor their children’s condition for 1-5 days after the onset of HFMD, which is a risk period. HFMD is an infectious disease caused by an enterovirus infection, which is more common in children and can be transmitted through the gastrointestinal tract, respiratory tract and contact. Most children have mild symptoms, with a prognosis of about 7-10 days, often accompanied by fever, anorexia and other manifestations. However, some children are in serious condition and may develop meningitis and encephalitis in 1-5 days, which is fatal. Therefore, parents need to pay attention to the mental state of the child, if there is depression, lethargy, headache, persistent fever, etc., they should consult the pediatrician or infection department in time. HFMD is a preventive disease, so children need to be isolated and treated in time to avoid infection. Parents need to do a good job of caring for their children, such as fever can use warm water baths, antipyretic patches and other physical cooling methods to relieve the discomfort of the child.
