Signs & symptoms of COVID
COVID often begins with mild symptoms that feel like a cold or the flu. These can start 2 to 14 days after virus exposure. Symptoms usually develop in stages instead of happening all at once. For some people, COVID infection progresses to more serious and even life-threatening conditions.
Severe COVID-19: What puts you at risk?
COVID-19 can cause severe illness regardless of age or health status, but the risk is even greater if you’re in a high-risk group. You are thought to be at high risk if you are 60 years and older, and/or have pre-existing health conditions (such as diabetes, asthma, chronic lung disease, and heart failure).

6 ways to help prevent COVID
Getting a current COVID vaccine is one of the best ways to help protect yourself against new COVID variants. When COVID spikes, it’s a good idea to make sure you’re up to date with your vaccination. It may also help protect people around you who are at higher risk for COVID, such as those who are immunocompromised. Vaccines train your immune system to fight the virus effectively, significantly lowering the risk of severe illness and reducing the spread within communities.
Play it smart by staying up to date with your yearly vaccines. The Centers for Disease Control (CDC) recommend COVID vaccination to be a part of your ongoing protection as new variants continue to emerge.
Get vaccinated and boosted

Covering your nose and mouth with a mask can help prevent the spread of the COVID virus.
Maintain good hand hygiene
Washing your hands helps keep germs and respiratory infections from spreading.
Regular testing
Testing for COVID if you have symptoms or if you think you have been exposed can help you make a plan to get treatment if needed, and to take steps to avoid spreading the infection to others.
Stay home if sick
Avoiding others can help keep you from spreading COVID to people who are high-risk.
Strengthen your immune system
Staying up to date with yearly COVID vaccination helps keep your immune system prepared throughout the year.
