Hand-Foot-and-Mouth Disease (HFMD): A Comprehensive Guide


Hand-foot-and-mouth disease (HFMD) is a common, contagious viral infection that primarily affects young children, although it can occur in adults as well. It is caused by a group of viruses called enteroviruses, most commonly Coxsackievirus A16 and Enterovirus 71.


The hallmark symptoms of HFMD are:

  • Fever: Typically between 99-101°F (37-38°C)
  • Rash: A painful, itchy rash with small, red blisters on the palms of the hands, soles of the feet, and inside the mouth
  • Sore throat
  • Runny nose
  • Loss of appetite
  • Fatigue
  • Nausea and vomiting

Symptoms usually develop 3-6 days after exposure to the virus and can last for 7-10 days.


HFMD is highly contagious and can be spread through:

  • Contact with infected droplets: When an infected person coughs or sneezes
  • Contact with contaminated surfaces or objects: Such as toys, doorknobs, or shared utensils
  • Contact with infected feces: In rare cases


HFMD can usually be diagnosed based on a physical examination and the patient’s symptoms. In some cases, a throat swab or stool sample may be collected to confirm the diagnosis.


There is no specific cure for HFMD, and treatment is focused on relieving symptoms. Recommended measures include:

  • Rest: Encourage the patient to get plenty of rest to promote healing.
  • Pain relievers: Acetaminophen or ibuprofen can help reduce fever and discomfort.
  • Mouth rinses: Use saltwater or baking soda rinses to soothe mouth sores.
  • Stay hydrated: Drink plenty of fluids to prevent dehydration.
  • Avoid sharing personal items: To prevent the spread of infection.


Most cases of HFMD are mild and resolve without complications. However, in rare cases, severe complications can develop, including:

  • Dehydration: If the patient vomits or refuses to drink fluids, they may become dehydrated.
  • Meningitis: An inflammation of the membranes around the brain and spinal cord.
  • Encephalitis: An inflammation of the brain.
  • Pulmonary edema: Fluid accumulation in the lungs.
  • Myocarditis: Inflammation of the heart muscle.


There is no vaccine to prevent HFMD. However, there are several steps that can be taken to reduce the risk of infection, including:

  • Frequent handwashing: Wash your hands thoroughly and frequently with soap and water.
  • Covering coughs and sneezes: Use a tissue or your elbow to cover your mouth and nose when coughing or sneezing.
  • Disinfecting surfaces: Clean and disinfect surfaces that may be contaminated with the virus.
  • Avoid sharing personal items: Do not share cups, utensils, or towels with others.
  • Staying home when sick: If you have symptoms of HFMD, stay home from work or school to avoid spreading the infection.

When to Seek Medical Attention

Seek medical attention if you or your child experience any of the following symptoms:

  • Persistent fever over 101°F (38°C)
  • Severe headache
  • Neck stiffness
  • Confusion
  • Difficulty breathing
  • Chest pain
  • Vomiting or diarrhea that lasts more than 24 hours


Hand-foot-and-mouth disease is a common and contagious viral infection that typically causes mild symptoms. However, it can lead to severe complications in rare cases. Prevention is key, and frequent handwashing, proper hygiene, and staying home when sick can significantly reduce the risk of infection. If you or your child develop symptoms of HFMD, it is important to seek medical attention promptly, especially if they are severe or if there is concern about complications.
