Hand, Foot and Mouth Disease (HFMD) Information 

HFMD is a common viral illness that mostly affects infants and young children. It is usually mild, and most children recover fully within 7–10 days.  

What are the symptoms? 

Your child may have: 

• Fever 

• Sore throat 

• Painful sores in the mouth 

• Rash or small blisters on hands, feet, or sometimes the diaper area 

• Decreased appetite or irritability 

  

How does it spread? 

HFMD spreads easily through: 

• Coughing and sneezing 

• Saliva and nasal secretions 

• Contact with blisters 

• Contact with contaminated surfaces (toys, tables, etc.) 

  

When should my child stay home? 

Keep your child home if they have: 

• Fever 

• Severe discomfort or are not feeling well 

• Open or draining blisters 

• Difficulty participating in normal activities 

Your child can return to school or childcare when: 

• Fever-free for 24 hours (without medication) 

• Feeling well enough to participate 

• Blisters are no longer actively draining 

  

How can I help prevent the spread? 

• Wash hands often with soap and water 

• Clean and disinfect frequently touched surfaces 

• Avoid sharing cups, utensils, or personal items 

• Teach children to cover coughs and sneezes 

  

When should I call a doctor? 

Contact your healthcare provider if your child: 

• Is not drinking enough fluids or showing signs of dehydration 

• Has severe pain or symptoms that worsen 

• Has a weakened immune system 

• Symptoms last longer than expected 

  

When does Public Health get involved? 

HFMD is not usually reportable, but schools or childcare programs may contact Public Health if: 

• There are 3 or more related cases within a few days, or 

• There is concern about rapid spread
