Determining If You Have a Cold, Flu or COVID-19

Cold and flu season is here, and you’re sick. How can you tell what you’re sick with and if you need to see a doctor?

With the start of cold and flu season coinciding with the COVID-19 pandemic it can be confusing to determine what symptoms relate to which illness.

Colds, flu-like illnesses and COVID-19 share many symptoms. These include fever, which tends to relate more to the flu or COVID-19 and merits contacting your primary care provider.

“With any cold and flu-like illness, we continue to ask patients to call their health care providers first thing, so their symptoms can be assessed, and patients can be routed to appropriate treatment and testing,” said Adam Brady, MD, of Samaritan Infectious Disease.

Regardless of your symptoms, you should stay home and limit contact with other people to avoid spreading the illness. Make sure to disinfect high-touch areas — such as doorknobs and countertops — and wash your hands frequently.

To reduce your chances of catching the flu, be sure to get a flu shot. More information on where you can get a flu shot can be found at
