HFMD is a contagious disease caused by various enteroviruses. More than 20 types of enteroviruses can cause HFMD, among which Coxsackievirus A16 and Enterovirus 71 are the most common. Patients with HFMD are highly contagious from the early stages of illness through recovery. These viruses can spread to others via respiratory droplets, direct contact, fecal-oral transmission, and other routes. Individuals in crowded settings or those in close contact with infected patients—especially children with immature immune systems—are particularly susceptible to contracting HFMD. Effective preventive measures, such as avoiding contact with infected children, frequent handwashing, and maintaining a clean environment, can significantly reduce the risk of transmission. In the later stages of the disease, the viral load in patients gradually decreases, leading to reduced contagiousness.

To prevent the spread of HFMD, it is recommended to strengthen personal hygiene education and cultivate good hygiene habits. Avoid taking children to crowded public places whenever possible, ensure adequate indoor ventilation, regularly clean and disinfect items and toys used by infected individuals, and avoid sharing personal items. If symptoms suggestive of HFMD—such as fever or rash—appear, immediate medical consultation is advised, followed by targeted treatment under a doctor's guidance.
