COVID-19 is a contagious respiratory illness caused by the SARS-CoV-2 virus. COVID-19 most often causes respiratory symptoms that can feel much like a cold, the flu, or pneumonia. Most people with COVID-19 have mild symptoms, but some people become severely ill. Some people, including those with minor or no symptoms will develop Post-COVID Conditions – also called “Long COVID”.
Some people are more likely than others to get very sick if they get COVID-19. This includes people who are older, have a weakened immune system, have certain disabilities, or have underlying health conditions. It is especially important that people with these risk factors take steps to prevent severe COVID-19 infections, including staying up to date on vaccines and taking treatment medications if infected.
