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.

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.

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.

Hand, foot, and mouth disease transmission routes

Hand, foot, and mouth disease is caused by an intestinal virus infection, characterized by a rash of scattered maculopapular and vesicular lesions on the hands, feet, mouth, and buttocks. Generally, the prognosis is good. The disease is quite contagious, primarily spreading through the gastrointestinal tract, respiratory tract, and close contact. Therefore, during peak seasons of hand, foot, and mouth disease, children should stay at home and avoid crowded places and playing with children who have the disease. The highest incidence of this disease is among children under three years old, so it is essential to pay attention to the prevention and health care of infants. If a child in kindergarten is found to have the disease, they should rest at home and not return to the kindergarten immediately.
