Hand, Foot, and Mouth Disease in Young Children - Pediatrics

The doctor diagnosed the child with a possible enterovirus infection?


Hello Doctor: My daughter will turn two years old on January 9th next year.
A few days ago, she had a fever and we took her to see a doctor.
The doctor said she had white spots in her mouth, which might indicate a hand, foot, and mouth disease.
He prescribed three bottles of medicine and a rectal suppository for fever.
Two days later, she no longer has a fever! However, after drinking formula milk, she coughs so much in her sleep that she vomits! This has been happening for two days, and she has vomited in her sleep! Could this indicate a problem with her intestines? Her stomach feels bloated! While sleeping, she has a rattling sound in her breathing.
Her bowel movements are bright yellow and watery, with a slightly sour smell! This is our first child, so we are not very experienced.
Please guide us, thank you!

Young children have a relatively small stomach capacity, so they can easily cough severely enough to vomit.
If the diarrhea has a sour smell, it may indicate a gastrointestinal infection (some colds can present with gastrointestinal symptoms).
Since your child's condition has changed, it is advisable to consult a pediatrician for further evaluation and treatment.

More Info


Hand, Foot, and Mouth Disease (HFMD) is a common viral infection that primarily affects young children, typically under the age of 5. It is caused by several different viruses, most commonly the coxsackievirus. The disease is characterized by fever, mouth sores, and a rash on the hands and feet. Understanding HFMD is crucial for parents, especially when it comes to recognizing symptoms and knowing how to manage the condition.

In your case, it seems that your daughter has already shown some symptoms consistent with HFMD, such as fever and the presence of white spots in her mouth. These white spots are often painful sores that can make it difficult for children to eat or drink, leading to dehydration. The fever typically lasts for a few days, and once it subsides, the rash may appear, usually starting on the palms of the hands and soles of the feet, but it can also appear on the buttocks and legs.

The symptoms you describe, such as coughing and vomiting after drinking formula, could be related to several factors. It is not uncommon for children with HFMD to experience gastrointestinal symptoms, including nausea and diarrhea. The fact that your daughter is experiencing a bloated stomach and has watery, yellow stools with a sour smell may indicate that her digestive system is reacting to the viral infection. However, it is essential to monitor her closely, as these symptoms could also suggest a secondary issue, such as a gastrointestinal infection or intolerance to the formula.

The coughing and the presence of phlegm during sleep could be due to several reasons. It might be a result of post-nasal drip, which can occur when a child has a viral infection. The mucus can irritate the throat, leading to coughing, especially when lying down. If the cough persists or worsens, or if she shows signs of respiratory distress (such as difficulty breathing or wheezing), it would be prudent to consult a pediatrician.

In terms of management, here are some recommendations:
1. Hydration: Ensure your daughter stays well-hydrated. Offer her plenty of fluids, such as water, diluted juice, or oral rehydration solutions. If she is reluctant to drink due to mouth sores, try offering cold liquids or popsicles, which can soothe the pain.

2. Pain Relief: If she is experiencing discomfort from mouth sores or fever, over-the-counter pain relievers like acetaminophen or ibuprofen can be used, but always consult your pediatrician for the appropriate dosage.

3. Diet: Offer soft foods that are easy to swallow and less likely to irritate her mouth, such as yogurt, applesauce, or mashed potatoes. Avoid acidic or spicy foods that could exacerbate mouth pain.

4. Monitoring Symptoms: Keep an eye on her symptoms. If she continues to vomit, has persistent diarrhea, or shows signs of dehydration (such as dry mouth, lack of tears, or decreased urination), seek medical attention.

5. Rest: Ensure she gets plenty of rest to help her body recover from the infection.

6. Consulting a Doctor: Since this is your first child, it’s understandable to have concerns. If you feel uncertain about her symptoms or if they worsen, do not hesitate to reach out to her pediatrician for further evaluation and guidance.

In conclusion, while HFMD is generally a mild illness that resolves on its own, it is essential to monitor your daughter's symptoms closely and provide supportive care. If you have any concerns about her health or if her symptoms change, seeking medical advice is always the best course of action.
