Are most adults immune to hand foot and mouth disease?

Most adults are not immune to hand, foot, and mouth disease (HFMD), as it is primarily caused by enteroviruses, particularly coxsackievirus. While adults can contract the disease, it is more common in young children due to their developing immune systems and increased exposure in group settings. Some adults may have been exposed to the virus in childhood and developed immunity, but many can still get infected if they come into contact with the virus. Generally, HFMD is mild in adults but can still cause symptoms.
