Hand, Foot, and Mouth Disease (HFMD)
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.
How many days does hand, foot and mouth disease have a fever?
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.
Causes of Hand, Foot, and Mouth Disease
Hand, foot, and mouth disease is a rash illness characterized by scattered papules and vesicles on the hands, feet, mouth, and buttocks, caused by an enterovirus infection. It is a contagious disease caused by a viral infection, specifically by Coxsackievirus A16 and Enterovirus 71, which are part of the enterovirus group. Other Coxsackie enteroviruses can also cause hand, foot, and mouth disease. Common enterovirus infections can also lead to hand, foot, and mouth disease. This means that children who have had hand, foot, and mouth disease can potentially get it again, and this is important knowledge for everyone to understand.
Is hand, foot, and mouth disease dangerous?
Hand, foot, and mouth disease is a common pediatric disease caused by an intestinal viral infection, characterized by fever and rash, with severities ranging from mild to severe. If caused by a typical enterovirus infection, hand, foot, and mouth disease generally recovers quickly with antiviral treatment and proper care of the mouth and skin. However, if caused by an EV71 virus infection, it poses certain risks. This is because the EV71 virus can affect the central nervous system, leading to symptoms such as increased intracranial pressure and respiratory and circulatory dysfunction. These complications can result in respiratory failure and cardiac failure, which are severe manifestations. Therefore, hand, foot, and mouth disease caused by the EV71 virus carries certain risks. Thus, it is important to administer a vaccine made from the EV71 virus to children to prevent severe hand, foot, and mouth disease.
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.
