If it is only mild HFMD, the condition is not serious and the symptoms are not obvious, there is a possibility of self-healing, about a week or so, the condition will gradually improve. However, waiting for self-cure is not generally recommended at this time because it cannot be ruled out that mild HFMD will progress gradually and be prone to other complications, such as brainstem encephalitis and encephalomyelitis. After the diagnosis of HFMD is confirmed, close monitoring of the condition and localized care are required. Topical ribavirin ointment can be used when a rash is found on the surface of the skin, and ribavirin spray can be used when herpes develops in the mouth. Most mild cases of HFMD can be cured within a short period of time with regular treatment and have a good prognosis. The detection of mild hand, foot and mouth disease should not be taken lightly, it is recommended to take the child to the doctor in a timely manner, and under the guidance of specialized physicians targeted treatment.
