Hand, Foot, and Mouth Disease (HFMD)
How is hand, foot, and mouth disease transmitted?
Hand, foot, and mouth disease is an infectious disease caused by enteroviral infections. There are more than 20 types of enteroviruses that can cause hand, foot, and mouth disease, but the most common are Coxsackievirus A16 and Enterovirus 71. The main clinical symptoms include pain in the mouth, anorexia, low fever, and the appearance of small vesicles or ulcers on the hands, feet, mouth, and other areas. Most children can recover in about a week, but a few may develop serious complications such as myocarditis, pulmonary edema, and aseptic meningitis. The general transmission routes are through the digestive tract, respiratory tract, and close contact, such as through droplets, sharing utensils, and hand-to-mouth contact, etc.
Hand, foot, and mouth disease is spread through:
Hand, foot, and mouth disease is an infectious disease caused by enteroviruses. There are more than 20 types of enteroviruses that can cause the disease, among which Coxsackievirus A16 and Enterovirus 71 are the most common. It frequently occurs in children under the age of 5 and manifests as mouth pain, loss of appetite, low fever, and small blisters or ulcers on the hands, feet, and mouth. Most affected children can recover within about a week. The main routes of transmission for hand, foot, and mouth disease can include the gastrointestinal tract, as well as respiratory transmission, and close contact such as through saliva, cough droplets, etc. Sharing utensils can also spread the disease.
Does hand, foot and mouth disease hurt?
Hand, foot, and mouth disease is caused by an intestinal virus, mainly manifested in children as blisters on the hands, feet, mouth, and buttocks. Some cases may involve fever, while others may have no fever or only mild, low-grade fever. Oral and pharyngeal blisters are quite common, causing oral pain and discomfort. Many children who contract hand, foot, and mouth disease experience a decrease in appetite, which is related to oral and pharyngeal blisters causing pain that affects swallowing and eating.
How long should hand, foot, and mouth disease be isolated?
Hand, foot, and mouth disease is an infectious disease caused by enterovirus infection. There are more than 20 common types of enteroviruses, with Coxsackievirus A16 and Enterovirus 71 being the most common. The main clinical symptoms include fever, mouth pain, loss of appetite, and small blisters or ulcers on the hands, feet, and mouth. Most affected children can heal on their own in about a week, so ordinary cases can be isolated for about a week until all the rashes have crusted over and disappeared. However, for severe cases, the isolation period should be extended appropriately, possibly lasting 10-14 days, or even longer.
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.
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.
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.
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.)
Is hand, foot, and mouth disease contagious?
Hand, foot, and mouth disease is a contagious disease caused by an infection of enteroviruses. There are more than 20 types of enteroviruses that cause the disease, with Coxsackievirus A16 and Enterovirus 71 being the most common. The main clinical manifestations of this disease include blisters on the hands, feet, mouth, and buttocks. Some patients may experience fever, while others may have no fever or only a mild fever. The disease is contagious and primarily transmitted through contact. For example, it can be spread through saliva, droplets, hand-to-mouth contact, and contact with the secretions from the blisters, among other methods.
Characteristics of hand, foot, and mouth disease rash
Hand, foot, and mouth disease is a rash disease caused by an intestinal virus infection, characterized by scattered maculopapular and vesicular rashes on the hands, feet, buttocks, and other areas. Typically, small vesicles appear on the oral mucosa, or they may already have ruptured into shallow ulcers, primarily located on the tongue, buccal mucosa, palate, and inner lips. Subsequently, rashes appear on the hands and feet, most commonly as maculopapules, which then develop into vesiculopapules about three to seven millimeters in size. The vesicles have a relatively thick covering and are surrounded by reddened skin, predominantly located at the extremities. Sometimes, they may extend to the arms, legs, buttocks, or perineal area. The distribution of the rash is centrifugal, with the number of lesions varying from a few to dozens. Generally, the lesions absorb on their own within two to three days without desquamation, scarring, or pigmentation. The vesicles and ulcers in the mouth mostly heal on their own within a week.
