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 characteristics

Hand, foot, and mouth disease is an infectious disease caused by enterovirus, primarily characterized by scattered maculopapular or vesicular rashes on the hands, feet, mouth, and buttocks. These rashes are quite distinctive; initially, there is a fever, followed by rashes on hands and feet. These are commonly found between the fingers, starting as maculopapular rashes and gradually turning into vesicular rashes. The rashes, measuring three to seven millimeters, have a firm base with slightly thickened skin over the blisters and are surrounded by erythema. They occur mainly on the extremities but can sometimes spread to the arms, legs, buttocks, or perineal area. The distribution of the rash is centrifugal, ranging from a few to dozens in number. Generally, the rashes absorb on their own within two to three days without scaling, scarring, or pigmentation, and oral blisters or ulcers usually heal within a week.

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.

How to disinfect hand, foot, and mouth disease?

Hand, foot, and mouth disease is an acute infectious disease caused by a viral infection. It mainly spreads through the respiratory tract, digestive tract, and close contact. Being in contact with a carrier or a child with the disease can result in transmission. It is important to properly handle the infected child's feces and other excretions. Clothes can be soaked in a 3% bleach solution and exposed to sunlight. Keep the room well-ventilated. Other contaminated daily items, such as toys or closely contacted objects like dishware and children's eating utensils, should be disinfected promptly.
