Your child has a sore throat, cough, and a high fever. Is it just a cold? Or could it be the flu or an RSV infection? Or maybe COVID-19?
All these illnesses are caused by viruses that infect the respiratory tract. All are contagious and can spread easily from person to person. And they cause some similar symptoms. So it can be hard to tell them apart.
Here are some things to look for if your child gets sick.
Common Cold
Symptoms
Cold symptoms can be caused by many different viruses and usually are mild. They often include a scratchy throat, a runny or stuffy nose, and sneezing. If there's a fever, it is not high. A child with a cold usually feels okay and has a good appetite and normal energy levels.
Tests & Treatment
There is no test for the common cold, and no specific treatment. It just needs to run its course.
Prevention
Because so many viruses cause colds, there's no vaccine that can prevent them. But it's always a good idea to wash hands well and often, cover coughs and sneezes, and avoid people who are sick.
The flu usually makes kids feel worse than if they have a cold. But it's not always easy to tell the difference. Here are tips on what to look for — and what to do.
