The coronavirus disease (COVID-19) is caused by a virus. Symptoms may include a fever, a cough, and shortness of breath. It can spread through droplets from coughing and sneezing, breathing, and singing. The virus also can spread when people are in close contact with someone who is infected.
Most people have mild symptoms and can take care of themselves at home with medicine to reduce symptoms. Talk to your doctor. They might have you take medicine to help prevent serious illness. If your symptoms get worse, you may need care in a hospital. Treatment may include medicines, plus breathing support such as oxygen therapy or a ventilator.
It's important to not spread the virus to others. If you have COVID-19, wear a well-fitting mask anytime you are around other people. Isolate yourself while you are sick. Leave your home only if you need to get medical care or testing.

Most people who get COVID-19 will recover with time and home care. Here are some things to know if you're caring for someone who's sick.
Common symptoms include a fever, coughing, and feeling short of breath. Urge the person to get extra rest and drink plenty of fluids to replace fluids lost from fever.

Call 911 or emergency services if the person has any of these symptoms:
Some people are more likely to get very sick and need medical care. Call the doctor as soon as symptoms start or the person tests positive for COVID-19.
