A common viral illness, HFMD usually affects infants and children younger than five years old. However, it can sometimes occur in older children and adults. HFMD is spread from person to person by close contact with an infected person or contact with virus-contaminated surfaces. Infected persons are most contagious during the first week of illness.
Symptoms of HFMD include:
- Fever
- Sore throat
- Painful mouth sores that blister
- Rash commonly found on the hands and feet
- Poor appetite
- A general feeling of being unwell
To prevent spreading to others, children with HFMD should not go to school or childcare for at least 24 hours after fever is gone without the use of a fever-reducing medicine and they have no uncontrolled drooling due to mouth sores.
Prevention Tips!
- Wash hands often with soap and water for at least 20 seconds. Avoid touching your face.
- Clean and disinfect frequently touched surfaces and shared items.
- Avoid close contact with people who have HFMD.
- Cover your nose and mouth when you cough or sneeze.
Most people get better on their own in seven to 10 days with minimal or no medical treatment. If you have questions about HFMD, contact your healthcare provider.
