Things not to do when your child has a viral infection

Medically reviewed by Dr. Betsy Koickel, MD on September 10, 2026.

When your child is sick, it’s natural to want to take immediate steps to help them feel better. You may want to lower their fever, get them eating normally, help them sleep, or get them back to school as soon as possible. But when it comes to a viral infection in kids, what you don’t do can matter just as much as what you do.

Most viral infections improve with time, rest, fluids, and supportive care to help the body heal. The key is knowing how to help a child with a viral infection while avoiding common mistakes. Here’s what not to do when a child has a viral infection and what to do instead.

Don't insist on antibiotics for a viral infection in kids

Antibiotics treat bacterial infections, not viral infections. That means they won’t help common viral illnesses like colds, many sore throats, most cases of bronchitis, or respiratory infections. Asking for antibiotics “just in case” may seem harmless, but unnecessary antibiotic use can cause side effects and contribute to antibiotic resistance.

If you’re wondering how to treat a child with a viral infection, the first step is supportive care to help the body fight off the virus. This may include rest, fluids, fever management when needed, and monitoring symptoms. A healthcare provider can help determine whether your child’s symptoms are likely viral or if they need further testing to determine the cause.

Don't send them back to school before symptoms are gone

If you’re asking if your child can go to school with a viral infection, the answer depends on their symptoms and school policy. How long a child is contagious with a viral infection varies by virus. Some children are most contagious early in the illness, while others may continue spreading germs for several days. When in doubt, give them more time to rest.

In general, children should stay home if they have a fever, vomiting, diarrhea, a severe cough, or significant fatigue. Many schools require children to be fever-free for at least 24 hours without fever-reducing medicine before returning to the classroom.

Don't stress about appetite; focus on keeping them hydrated

One of the most common child viral infection treatment mistakes is worrying too much about food. A child who skips a meal or eats less than usual is not always a reason to panic. Appetite often returns when they feel better.

Hydration is more important than food when fighting a viral illness. Encourage small sips of water, diluted juice, broth, or popsicles to maintain hydration. Watch for signs of dehydration, such as very dark urine, fewer wet diapers or bathroom trips, dry mouth, dizziness, or unusual sleepiness.

If your child is willing to eat, keep it simple. Toast, soup, crackers, rice, applesauce, bananas, yogurt, or other easy foods all work.

Don’t pile on over-the-counter medications

Over-the-counter medications can be helpful, but more medicine is not always better. Avoid giving multiple products that contain the same active ingredient, such as acetaminophen, because this can lead to accidental overdosing.

Always choose medication based on your child’s age and weight, and follow the label carefully. Do not give aspirin to children or teenagers unless a healthcare provider specifically tells you to. Cough and cold medications may not be appropriate for young children, so check with a clinician or pharmacist if you are unsure.

Don’t worry about breaking their routine

Sick days are not the time to worry about perfect routines. Extra screen time, naps at odd hours, skipped activities, and comfort foods are all ways to help your child feel better. Rest is part of recovery.

If your child wants to sleep more, let them. If they need extra comfort, offer it. You can return to normal routines once they are feeling better. 

When to seek care for your child

Most viral infections in kids improve with supportive care, but some symptoms need medical attention. Seek care if your child has trouble breathing, signs of dehydration, a high or persistent fever, severe ear pain, a stiff neck, confusion, or any concerning symptoms.
