COVID-19 is still part of our lives, much like the seasonal flu and other illnesses. We’re here with the information, care and support you and your family need to navigate COVID-19 and stay safe and healthy.
COVID-19 is a respiratory virus caused by the coronavirus SARS-CoV-2. It spreads easily from person to person and can cause illness ranging from mild cold-like symptoms to serious health problems.
COVID-19 symptoms can feel different for everyone and appear anywhere from 2–14 days after exposure to the virus. Common symptoms include:
To find out if you have COVID-19, your provider will give you a test that collects a sample from your nose or throat to check for the virus that causes it, called SARS-CoV-2.
There are two main types of viral COVID-19 tests:
Most people with COVID-19 have mild illness and can recover at home with rest, fluids and over-the-counter medicine to manage symptoms.
If you are at high risk for severe illness, your provider may prescribe an antiviral medicine like Paxlovid, which can help prevent serious complications. These medications are most effective within five days of when your symptoms begin.
If your symptoms worsen suddenly, or you experience a high fever that doesn’t improve with over-the-counter medicine, contact your provider or visit your nearest urgent care.
If you have trouble breathing, chest pain, confusion or bluish color on your lips or face, call 9-1-1 or go to the nearest emergency room.

Most people with mild illness feel better in one to two weeks, though cough or tiredness may last a few weeks longer.
People with COVID-19 can spread the virus starting one to two days before symptoms appear and for up to eight to ten days after. Most transmission happens early, often just before symptoms start and in the first few days after they begin. Even people without symptoms can still pass the virus to others.
The first cases were reported in December 2019 in Wuhan, China. The virus quickly spread around the globe, and on March 11, 2020, the Centers for Disease Control (CDC) officially declared COVID-19 a global pandemic.
COVID-19 stands for “Coronavirus Disease 2019,” named for the virus that causes it and the year it was discovered.
