Can Kids Go to School With a Low-Grade Fever?

Fever and School: What Ontario Parents Need to Know

Your child woke up with a slight fever and you're wondering if they can still go to school. The short answer is no – even a low-grade fever means your child should stay home. This protects other kids and gives your little one the rest they need to recover.

What counts as a fever?

A fever is when your child's body temperature rises above normal to fight off an infection. Normal body temperature is around 37°C (98.6°F), but it naturally fluctuates throughout the day.

Most doctors consider a low-grade fever to be between 37.2°C and 38.3°C (99°F to 101°F). While this might seem mild, it's still your child's immune system working hard against something, whether it's a virus, bacteria, or other illness.

Even if your child seems okay otherwise, that low-grade fever is telling you their body is fighting something off. Sending them to school means they could spread whatever they have to classmates and teachers, and the stress of a school day can make them feel worse.

What you might notice

- Temperature between 37.2°C and 38.3°C (99°F to 101°F)

- Feeling warm to the touch

- Slight fatigue or wanting to rest more

- Mild headache

- Not quite their usual energetic self

- Flushed cheeks or looking a bit pale

What helps at home

Keep your child comfortable with plenty of rest and fluids. Dress them in light, breathable clothing and keep the house at a comfortable temperature. Water, diluted juice, or popsicles can help prevent dehydration.

You can give children's acetaminophen or ibuprofen if they're uncomfortable, but only if your child is over the appropriate age for the medication. Always follow the dosing instructions on the package.

Most importantly, let them sleep as much as they want. Rest is the best medicine for fighting off whatever's causing that fever.

When to worry

Head to the emergency room if your child has trouble breathing, won't drink fluids, has a severe headache with neck stiffness, or seems very unwell regardless of the fever number.

Call your doctor or text Arlo if the fever lasts more than three days, goes above 38.5°C (101.3°F), or if you notice other symptoms like persistent vomiting, severe headache, or rash.

The takeaway

Trust that low-grade fever – it's your child's body telling you they need rest, not a day at school. You're making the right call keeping them home.

You can always text Arlo and talk to a provider in 5 minutes!
