A: People with COVID-19 should receive supportive care to help relieve symptoms. For people with laboratory confirmed COVID-19, illnesses have ranged from mild symptoms to severe illness and death. For severe illness, treatment should include care to support vital organ functions. Seek prompt medical attention if your illness gets worse (for example, you have difficulty breathing). Before seeking medical attention, call your health care provider and tell them that you have, or are being evaluated for, COVID-19. Put on a facemask before you enter the doctor’s office, clinic, or hospital.
