Hand, foot, and mouth disease (HFMD) is a highly contagious viral illness that is caused by a group of enteroviruses, most commonly coxsackievirus A16. The virus is spread through close contact with an infected person, such as through contact with saliva, mucus, or feces, or through contact with surfaces that have been contaminated with the virus. The time between exposure to the virus and the onset of symptoms is usually three to five days, although it can range from one to fourteen days.
The most common symptoms of HFMD are fever, sore throat, mouth sores, and a characteristic rash on the hands, feet, and in the mouth. The rash appears as flat, red spots on the palms, soles, and buttocks, and as small, painful blisters inside the mouth and on the tongue. Other symptoms may include headache, poor appetite, and muscle pain.
The main cause of HFMD is contact with an infected person or contact with surfaces that have been contaminated with the virus. The virus is highly contagious and can spread through contact with saliva, mucus, or feces, or through contact with objects or surfaces contaminated with the virus. It is important to practice good hygiene, such as washing hands frequently and avoiding contact with saliva, mucus, or feces from an infected person. It is also important to clean and disinfect objects and surfaces that may have been contaminated with the virus.
