COVID-19 is a disease caused by a type of coronavirus. This illness was first found in 2019 and has since spread worldwide (pandemic). Symptoms can range from mild, such as fever and body aches, to severe, including trouble breathing. COVID-19 can be deadly.
Coronaviruses are a large group of viruses. Some types cause the common cold. Others cause more serious illnesses like Middle East respiratory syndrome (MERS) and severe acute respiratory syndrome (SARS).
Your immune system may not work well because of certain medicines to treat cancer or autoimmune disease or ones needed after an organ transplant. Taking steroid medicines for a long time can also weaken your immune system. Other causes include certain health problems, as well as immune problems that run in your family.
A weakened immune system makes it more likely that you'll get very sick from COVID-19. And the COVID vaccine may not work as well for you.
