Hand, Foot, and Mouth Disease: Symptoms and Recovery - Pediatrics

More Info

---

Hand, Foot, and Mouth Disease (HFMD) is a common viral infection primarily affecting children, caused by enteroviruses, most notably coxsackievirus. It is characterized by fever, mouth sores, and a rash on the hands and feet. Understanding the symptoms and recovery process is essential for parents, especially when dealing with multiple children affected by the disease.


Symptoms of Hand, Foot, and Mouth Disease
The symptoms of HFMD typically begin with a mild fever, reduced appetite, sore throat, and a general feeling of being unwell. Within a day or two, painful sores may develop in the mouth, which can make eating and drinking uncomfortable. These sores often appear as red spots that can blister and may ulcerate.

In addition to mouth sores, a rash may develop on the hands, feet, and sometimes the buttocks. The rash can present as red spots, sometimes with blisters. The blisters can be quite large and may cause discomfort, but they usually resolve on their own without the need for medical intervention.


Recovery Process
Recovery from HFMD generally occurs within 7 to 10 days. In your case, it’s encouraging to hear that your daughter’s throat sores have healed and that your son’s appetite has improved. This indicates that they are on the right path to recovery. The large blisters on your son’s feet may take a bit longer to resolve, but they typically do not require treatment unless they become infected or cause significant pain.


Management of Symptoms
While there is no specific antiviral treatment for HFMD, supportive care is crucial. This includes:
1. Pain Relief: Over-the-counter medications like acetaminophen or ibuprofen can help alleviate pain and reduce fever.

2. Hydration: Ensuring that your children stay well-hydrated is vital, especially if they have mouth sores that make drinking uncomfortable. Offering cold fluids or ice pops can be soothing.

3. Avoiding Irritants: Soft foods that are easy to swallow can help prevent further irritation of mouth sores.


Concerning the Blisters
As for the large blisters on your son’s feet, they usually will resolve on their own. It’s important to keep the area clean and avoid popping the blisters, as this can lead to infection. If your son is not in pain and is able to walk without difficulty, this is a good sign. However, if you notice any signs of infection (increased redness, warmth, pus, or fever), it would be wise to consult a healthcare provider.


Risk of Re-infection
Regarding your question about the risk of re-infection while staying at home, it’s important to note that HFMD is contagious. The virus can spread through direct contact with an infected person’s bodily fluids, such as saliva, blister fluid, or respiratory droplets. If your children are already infected, they are not at risk of catching the virus again from each other. However, they can still spread the virus to others until the blisters have healed and they are symptom-free.


Conclusion
In summary, your children are likely on the mend, and the symptoms you described are typical of HFMD. The blisters should resolve with time, and supportive care will help manage their discomfort. Keeping them at home until they are symptom-free is a good practice to prevent spreading the virus to others. If you have any concerns about their recovery or if symptoms worsen, do not hesitate to reach out to your pediatrician for further guidance.
