Hand, foot, and mouth disease is a common exanthematous infectious disease in children caused by enterovirus infections. Most cases are mild to moderate and can be treated at home with oral medication. Doctors generally prescribe antiviral medications, and if the child's temperature exceeds 38.5 degrees Celsius, antipyretic medications are also required. If there is discomfort in the throat, some medications can be sprayed to relieve local discomfort. For severe cases, such as those caused by EV71 virus infection, it is crucial to be vigilant. This type of infection can lead to symptoms involving the nervous system and may rapidly progress to severe conditions. Therefore, if it is confirmed that the hand, foot, and mouth disease is caused by EV71 infection and the child's condition is serious, hospitalization should be promptly sought. Additionally, for children under three years old, it's important to actively vaccinate against hand, foot, and mouth disease to prevent illness caused by EV71 virus infection.

Characteristics of hand, foot, and mouth disease rash

Hand, foot, and mouth disease is a rash disease caused by an intestinal virus infection, characterized by scattered maculopapular and vesicular rashes on the hands, feet, buttocks, and other areas. Typically, small vesicles appear on the oral mucosa, or they may already have ruptured into shallow ulcers, primarily located on the tongue, buccal mucosa, palate, and inner lips. Subsequently, rashes appear on the hands and feet, most commonly as maculopapules, which then develop into vesiculopapules about three to seven millimeters in size. The vesicles have a relatively thick covering and are surrounded by reddened skin, predominantly located at the extremities. Sometimes, they may extend to the arms, legs, buttocks, or perineal area. The distribution of the rash is centrifugal, with the number of lesions varying from a few to dozens. Generally, the lesions absorb on their own within two to three days without desquamation, scarring, or pigmentation. The vesicles and ulcers in the mouth mostly heal on their own within a week.

Is hand, foot, and mouth disease serious?

Hand, foot, and mouth disease is a contagious viral infection primarily characterized by scattered vesicular or papular rashes on the hands, feet, mouth, and buttocks. It is generally a mild condition, and typical symptoms include fever and rash. It can be treated with oral medications and by taking care of oral and skin hygiene, usually healing quickly. Severe cases caused by the EV71 virus can lead to varying degrees of intracranial pressure. In such serious cases, prompt treatment with mannitol and furosemide to reduce intracranial pressure is necessary; corticosteroids may also be needed if required. For children with severe hypoxia, timely correction of oxygen deficiency is crucial, along with intravenous fluids to maintain stable blood pressure, respiration, heart rate, and microcirculation. (Please consult a professional physician for medication guidance and do not self-medicate.)

The main clinical symptoms include pain in the mouth, anorexia, low fever, and the appearance of small vesicles or ulcers on the hands, feet, mouth, and other areas. Most children can recover in about a week, but a few may develop serious complications such as myocarditis, pulmonary edema, and aseptic meningitis. The general transmission routes are through the digestive tract, respiratory tract, and close contact, such as through droplets, sharing utensils, and hand-to-mouth contact, etc.
