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.

Late-stage symptoms of hand, foot, and mouth disease

Hand, foot, and mouth disease is an acute infectious disease caused by enterovirus infection. Generally, there are more than twenty types of enteroviruses that cause hand, foot, and mouth disease, but the most common are Coxsackie virus A16 and enterovirus 71.

After crusting, the blisters gradually heal, but in some cases, the disease can progress to severe cases. For instance, complications such as encephalitis, brainstem encephalitis, myocarditis can occur, and some cases may develop neurogenic pulmonary edema, pulmonary hemorrhage, and circulatory failure, among others.

Symptoms of Hand, Foot, and Mouth Disease in Children

The symptoms of hand, foot, and mouth disease in children primarily result from viral infections of the intestine, a common communicable disease particularly prevalent among children under five, especially those under three years of age. The symptoms can be categorized into typical cases where most children experience a sudden onset of illness, often accompanied by upper respiratory tract infection symptoms such as fever, nasal congestion, runny nose, sneezing, loss of appetite, nausea, and vomiting. Some may also experience headaches. Additionally, rashes or vesicles may appear on the hands, feet, mouth, and buttocks, typically surrounded by inflammatory red skin with little fluid inside the vesicles. These lesions are characterized by being painless, non-itchy, non-crusted, and non-scarring. It is important to note that not all children will have simultaneous rashes on their hands, feet, and mouth areas. In severe cases, while most children experience only mild symptoms and can be isolated at home, some may develop complications involving the nervous system and impairment of respiratory and circulatory functions. This can manifest as muscle spasms, encephalitis, acute flaccid paralysis, cardiopulmonary failure, and neurogenic pulmonary edema. Therefore, once a severe case is identified, hospitalization is recommended to prevent potential fatalities or long-term sequelae.
