Prevention of Hand, Foot, and Mouth Disease

Hand, foot, and mouth disease is a common contagious exanthematous disease in pediatrics, caused by a viral infection with a certain epidemic nature. Its main modes of transmission include respiratory, digestive tracts, and close contact. During the epidemic, usually in the summer and autumn seasons, it is recommended that parents avoid taking children to public places. If a suspected case is found, timely isolation should be carried out, and close contacts should be quarantined for 7-10 days. Additionally, it's important to maintain good personal hygiene, such as washing hands before eating and after using the toilet, and to keep indoor ventilation in the home. If a child has been in contact with an infection or a suspected case of hand, foot, and mouth disease, it is crucial to monitor the child for any discomfort and check their temperature regularly. If the child feels unwell, take them to the hospital for treatment promptly.

Is hand, foot and mouth disease itchy?

Hand, foot and mouth disease is an infectious disease caused by enteroviruses. There are more than 20 types of enteroviruses that cause hand, foot and mouth disease, among which Coxsackievirus A16 and Enterovirus 71 are the most common. Its main clinical symptoms include mouth pain, decreased appetite, mild fever, and the appearance of small vesicles or small ulcers on the hands, feet, mouth, and other areas. Most infected children can recover in about a week. The rash of hand, foot and mouth disease typically appears on the hands, feet, buttocks, arms, and legs as maculopapular rash, which can later turn into vesicles. These vesicles are surrounded by an inflammatory red halo and contain relatively little fluid. The rash is not itchy. Thus, the rash of hand, foot and mouth disease is unlike other allergic rashes; it does not cause itching or discomfort.

Symptoms of hand, foot, and mouth disease

Hand, foot, and mouth disease is caused by an intestinal virus infection. It primarily manifests as a disseminated rash of maculopapules or vesicular papules on the hands, feet, mouth, and buttocks. The main symptoms of hand, foot, and mouth disease start with a fever in children, accompanied by a sore throat, reluctance to eat, and some children may have mild cough and runny nose. During a physical examination, small vesicles can be found on the oral mucosa, or they may have already ulcerated into shallow ulcers. Subsequently, rashes appear on the hands and feet, starting as maculopapules and slowly transforming into vesicular papules, about 3 to 7mm in size, with a firm base. The skin of the vesicle is slightly thicker, surrounded by erythema, and the rash is mostly located at the extremities. Sometimes, it can extend to the arms, legs, buttocks, and perineum, showing a centrifugal distribution. The number of rashes is relatively small, typically ranging from a few to several dozen. Most of them resolve on their own in 2 to 3 days without scaling, scarring, or pigmentation. Vesicles or ulcers in the mouth mostly heal within a week. Most cases of hand, foot, and mouth disease have a short duration and mild condition, with generally good prognosis.

Does hand, foot and mouth disease itch?

Hand, foot, and mouth disease is a condition caused by an intestinal virus, primarily characterized by herpes on the hands, feet, oral cavity, and buttocks. Some affected individuals may experience fever, ranging from low to moderate, while others may have high fever, and still others may not have any fever at all. The herpes is neither painful nor itchy, so there is no need for special treatment or handling of the herpes, just symptomatic treatment and timely fever reduction when necessary. For common cases, it is appropriate to orally administer some antiviral medications, and at the same time, take some traditional Chinese medicine that clears heat and detoxifies, while maintaining clean and hygienic skin.
