Echovirus is a type of virus that belongs to the Picornaviridae family. It is known to cause various illnesses, particularly in children, and can lead to symptoms such as fever, rash, and gastrointestinal issues. There are several serotypes of echovirus, each capable of causing different health problems. Transmission of echovirus typically occurs through the fecal-oral route, often in crowded settings like schools or daycare centers. While most infections are mild and self-limiting, some cases can lead to more serious conditions, such as meningitis or myocarditis. Good hygiene practices can help reduce the risk of infection.
