Hand-Foot-and-Mouth Disease (HFMD), though sometimes asymptomatic in its initial stages, typically manifests with various symptoms.
Key symptoms that may appear include:
* Fever
* Sore throat
* Blisters or sores on the tongue, gums, and inside of the cheeks
* Rash on the palms of the hands and soles of the feet
* Irritability in infants and young children
* Loss of appetite
* Difficulty swallowing
* Runny nose
The incubation period, the time from infection to the onset of symptoms, is generally 3 to 6 days. During this period, fever and sore throat are common; children may lose their appetite and experience a general feeling of malaise. One or two days after the onset of fever, painful sores can develop in the front of the mouth and throat. Simultaneously, red rashes may appear on the hands, feet, and sometimes the buttocks.
Sores developing in the back of the mouth and throat, however, may indicate a similar viral infection called herpangina, which can present with additional features such as sudden high fever and, in some cases, seizures. In rare instances, rashes may also be observed on other parts of the body, beyond the hands, feet, or mouth.
