The cure time for HFMD needs to be determined by the severity of the symptoms. In the case of mild HFMD, there are usually no obvious prodromal symptoms, mainly in the form of maculopapular or herpetic rashes on the hands, feet, mouth, and buttocks, and the symptoms can subside in about 5 days without leaving scars. In case of heavy cases, aseptic meningitis, encephalitis (brainstem encephalitis is the most serious), and acute delayed paralysis may appear in 1-5 days of onset, and death may occur within a short period of time. HFMD is a self-limiting disease, and most children get well within 1 week, and the rash can crust over and fall off within 2 weeks. In severe cases, with cardiovascular and neurological damage, hospitalization is required and may last up to 1-2 months. Children with the common type of HFMD can be treated in an infection unit or pediatric outpatient clinic. Parents should mainly pay attention to the care of their mouth and rash and observe their body temperature for any risk factors that may aggravate the disease, such as easy startling and shaking of limbs during sleep, and a persistent high temperature that does not subside, then they need to be warned.
