Vomiting and fever in children are often caused by viral infections, but can also signal more serious conditions. To care for your child at home:

Keep them hydrated: Offer small, frequent sips of water, oral rehydration solutions, or clear broths.
Watch for dehydration: Signs include dry mouth, no tears when crying, sunken eyes, reduced urination, or lethargy.
Manage the fever: Dress them lightly and ensure they rest.
Seek medical care if symptoms persist beyond 24 hours, worsen, or if your child shows signs of dehydration, severe pain, or a stiff neck.

Because vomiting and fever can stem from many different causes—ranging from a mild stomach bug to something requiring urgent care—understanding the likely cause helps you act quickly and confidently. Take a free, instant, online symptom check to get personalized insight into your child's symptoms and clear guidance on next steps.

Explanation

Vomiting and fever in children can often be caused by gastroenteritis, which is an infection of the stomach and intestines.

Steps to Handle Vomiting and Fever:

Hydration: It's important to keep your child hydrated. Offer small sips of water or an oral rehydration solution frequently.
Monitor Symptoms: Watch for signs of dehydration, like dry mouth, no tears when crying, or not urinating as much.
Rest: Ensure your child gets plenty of rest to help their body fight the infection.
Fever Management: You can manage fever with appropriate doses of fever-reducing medications, but only if advised by a healthcare provider.
Seek Medical Attention: If symptoms persist for more than a few days, or if your child seems very unwell, contact a healthcare provider.

Gastroenteritis usually improves on its own, but it's important to ensure your child stays hydrated and comfortable.
