Hand, foot, and mouth disease is caused by an intestinal virus infection and is characterized by acute fever and vesicles or papules on the hands, feet, mouth, buttocks, and other areas. There are more than 20 types of enteroviruses that cause this disease, with the most common being Enterovirus 71 and Coxsackievirus A16. In typical cases, the fever may last about two to three days, but there are also cases with mild symptoms where no fever appears, or only a low fever occurs, lasting one to two days. In severe cases, the fever may last longer, from three to five days or even more. Therefore, it can only be said that in most cases, the fever in typical cases may last about two to three days.

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.)

Initial symptoms of hand, foot, and mouth disease

Hand, foot, and mouth disease is a common pediatric exanthematous disease caused by an enterovirus infection, primarily manifesting on the hands, feet, mouth, and buttocks with scattered vesicular and pustular rashes. The incubation period for hand, foot, and mouth disease generally ranges from three to five days. The initial stage of the illness may include fever and sore mouth, or discomfort in the throat, leading to reluctance in children to eat. Accompanying symptoms might include mild coughing, runny nose, and throat discomfort. During a physical examination, a doctor may observe scattered small vesicles in the mouth mucosa, or shallow ulcers that have already erupted. These are mainly found on the lingual and buccal mucosa, as well as the mucosa on the inner side of the lips and upper palate. Subsequently, rashes appear on the hands and feet, generally starting as maculopapular rashes that slowly turn into vesicular rashes. These rashes are distributed eccentrically and typically resolve on their own within two to three days without scaling, scarring, or pigmentation. The oral vesicles usually heal on their own within a week. Some children with milder cases may only exhibit rashes or vesicular pharyngitis.

Does hand, foot, and mouth disease cause fever?

Hand, foot, and mouth disease is a contagious childhood exanthem caused by an intestinal virus infection. The primary symptoms of most hand, foot, and mouth diseases include fever, followed by rashes on the hands, feet, mouth, and buttocks, as well as vesicles in the throat. However, not all children with the disease necessarily experience continuous fever or any fever at all. Some only show symptoms after coming into contact with an infected person, with rashes on the hands, feet, mouth, and buttocks, and vesicles in the throat. In such cases, it is still considered hand, foot, and mouth disease, and fever is not a requisite for diagnosis. Thus, the presence of fever should not be solely relied upon for diagnosing the disease.
