The best way to know if you or your child is sick with flu, RSV, or COVID-19 is to get tested for these viruses.

Flu, RSV, and COVID-19 are respiratory illnesses that can have varying degrees of symptoms, from no symptoms to severe symptoms. You cannot tell the difference between these illnesses by symptoms alone because they have some of the same signs and symptoms. Common symptoms between the two viruses include fever, cough, fatigue, runny or stuffy nose, and several others.

You need specific testing to confirm if you are sick with either virus. You can test for COVID-19 at home, while most flu tests and RSV tests are administered by a medical professional. Contact your health care provider if you have questions about testing and treatment, especially if you or your child are at high risk for complications from flu, RSV, or COVID-19.
