Hand, Foot, and Mouth Disease: Symptoms and Care Tips - Pediatrics

More Info

---

Hand, Foot, and Mouth Disease (HFMD) is a common viral infection primarily affecting young children, although it can also occur in adults. It is most often caused by coxsackievirus, a member of the enterovirus family. The symptoms typically include fever, mouth sores, and a rash on the hands and feet. In your case, your daughter’s symptoms of fever followed by the appearance of water-filled blisters in the mouth and on the inner cheeks are classic signs of HFMD.

Regarding your concern about the potential for the virus to invade the nervous system and limbs, it is important to note that while HFMD is generally a mild illness, there can be rare complications. Most cases of HFMD do not lead to serious neurological issues. However, in some instances, particularly with certain strains of the virus, there can be complications such as viral meningitis or encephalitis, which are more serious conditions that affect the central nervous system. The symptoms you mentioned, such as involuntary shaking of the legs, could be a cause for concern and should be evaluated by a healthcare professional to rule out any serious complications.

To manage and care for your daughter during this illness, here are some tips:
1. Hydration: Ensure she stays well-hydrated. Children with HFMD may refuse to drink due to mouth sores, so offering cold fluids or ice pops can be soothing.

2. Pain Relief: Over-the-counter medications such as acetaminophen or ibuprofen can help relieve fever and discomfort. Always follow the dosing instructions based on her age and weight.

3. Soft Foods: Offer soft, bland foods that are easy to swallow and less likely to irritate mouth sores. Foods like yogurt, applesauce, and mashed potatoes can be good options.

4. Rest: Encourage her to rest as much as possible. The body needs energy to fight off the virus.

5. Monitor Symptoms: Keep a close eye on her symptoms. If she experiences worsening symptoms, such as difficulty breathing, persistent high fever, or signs of dehydration (such as dry mouth, lack of tears, or decreased urination), seek medical attention immediately.

6. Prevent Spread: HFMD is contagious, so practice good hygiene. Wash hands frequently, especially after diaper changes or using the bathroom. Avoid close contact with others until she is feeling better.

7. Follow-Up: If her symptoms do not improve or if you notice any new concerning symptoms, such as the shaking you mentioned, it’s crucial to consult with a healthcare provider for further evaluation.

In summary, while HFMD is usually a self-limiting illness, it’s essential to monitor your daughter’s symptoms closely and provide supportive care. If you have any concerns about her condition, especially regarding the shaking or any neurological symptoms, do not hesitate to seek medical advice.
