Coxsackievirus is a type of virus that belongs to the Enterovirus family. It is known to cause a range of illnesses, particularly in children. Symptoms can include fever, sore throat, and rash, and it is often associated with hand, foot, and mouth disease. The virus spreads through direct contact with an infected person's saliva, stool, or respiratory secretions. While most infections are mild and resolve on their own, coxsackievirus can occasionally lead to more serious conditions, such as viral meningitis or myocarditis. Good hygiene practices can help prevent its spread.
