Hand, foot, and mouth disease is a common viral infection primarily affecting young children. It is caused by viruses from the Coxsackievirus family and is characterized by sores in the mouth and a rash on the hands and feet. Symptoms may include fever, sore throat, and a general feeling of discomfort. The disease spreads easily through close contact, respiratory droplets, and contaminated surfaces. While it is usually mild and resolves on its own within a week or two, it can sometimes lead to complications. Good hygiene practices, such as frequent handwashing, can help prevent its spread.
