What is COVID-19?

Updated March 25

The latest strain of coronavirus, COVID-19, is a respiratory illness that, until December 2019, had not been seen in humans. The illness was first detected in China and has since spread around the world. The first cases of COVID-19 in Virginia were reported in early March.

COVID-19 causes symptoms much like the common cold or flu. Symptoms include fever, a worsening cough and shortness of breath. COVID-19 symptoms are more severe than those of the common cold and may last longer.  

If you were sick, how would you know if it was COVID-19 or something else, like the flu?

The image below compares symptoms of COVID-19, the flu and allergies. As with any illness, exact symptoms can vary from person to person. Fever, congestion, fatigue: What might your symptoms mean?

When to call your doctor

It’s important to call your primary care doctor or your child’s pediatrician if you have specific concerns or your symptoms seem to be getting worse. Your doctor will want to know is if you’ve traveled to an area where COVID-19 outbreaks have occurred, such as China, or if you’ve been in contact with someone within the past 14 days who has a confirmed case of the disease. If either of these is true, and you display symptoms linked to COVID-19, your doctor may choose to test you for the virus.

Practice prevention

With COVID-19 you can share germs before you start to experience symptoms. Symptoms may start to appear anywhere from 1-14 days after exposure -- or perhaps even more. This is why infection prevention measures -- including social distancing, hand hygiene, regular cleaning of high-touch surfaces and cough/sneeze etiquette – are so important.
