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.

What should I do about hand, foot, and mouth disease?

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.

How long should hand, foot, and mouth disease be isolated?

Hand, foot, and mouth disease is an infectious disease caused by enterovirus infection. There are more than 20 common types of enteroviruses, with Coxsackievirus A16 and Enterovirus 71 being the most common. The main clinical symptoms include fever, mouth pain, loss of appetite, and small blisters or ulcers on the hands, feet, and mouth. Most affected children can heal on their own in about a week, so ordinary cases can be isolated for about a week until all the rashes have crusted over and disappeared. However, for severe cases, the isolation period should be extended appropriately, possibly lasting 10-14 days, or even longer.
