COVID-19, Flu, Cold Symptoms

Figuring out what's making you sick these days can be tough. One cough can lead to a multihour Google search to determine whether it's the flu, COVID, or the common cold. It doesn't help that these illnesses have similar symptoms.

"Coronavirus and flu symptoms have significant overlap," Sandra Kesh, MD, deputy medical director and infectious disease specialist at Westmed Medical Group in Purchase, NY, tells POPSUGAR. "They both can cause fever, cough, breathing difficulties, fatigue, and many other symptoms." The flu can feel like the worst cold of your life, but symptoms come on suddenly and include fever, chills, and body aches, while colds tend to develop slowly.

So, how do you tell them apart? Here's a breakdown of some of the glaring differences between the cold, the flu, and COVID - and when to see a doctor.

Flu vs. COVID vs. Common Cold Chart of Symptoms

As Dr. Kesh noted, both COVID and the flu share a significant number of symptoms. However, the onset of symptoms varies between the viruses. According to the CDC, the flu has a tendency to suddenly overwhelm an infected person with an onslaught of symptoms that can last anywhere from three days to two weeks.

COVID symptoms appear two to 14 days after someone is infected with the virus, per the CDC website. Symptoms for mild COVID cases can last from one to two weeks, but a more severe infection causes symptoms for upwards of six weeks, according to Hopkins Medicine.

The common cold is by far the most low-key virus of these respiratory infections. Symptoms are generally milder and appear more gradually than with the flu. The common cold is also typically short-lived: symptoms generally last seven to 10 days, as opposed to flu symptoms, which can last for two weeks.

To better understand the differences in symptoms between the flu, the common cold, and COVID, here's a chart based off of the CDC site.

When Should You See a Doctor?

If you're experiencing flu-like symptoms and/or believe you have been exposed to COVID, purchase an at-home COVID test from your local drug store or visit your medical provider for a diagnosis. If you're elderly, pregnant, dealing with a chronic medical condition, or caring for a young child with flu-like or COVID symptoms, Dr. Kesh advises you to seek medical care immediately.

The best things you can do to protect yourself and your community from COVID, as well as from the cold and flu, is to wash your hands regularly, keep surfaces in your home and at work clean, and lead by example by staying home when you're sick and encouraging others to do the same.
