Coronavirus (COVID-19)
Overview
What is coronavirus (COVID-19)?
The coronavirus disease (COVID-19) is caused by a virus. It is an illness that was first found in December 2019. It has since spread worldwide.
The virus can cause fever, cough, and trouble breathing. In severe cases, it can cause pneumonia and make it hard to breathe without help. It can cause death.
This virus spreads person-to-person through droplets from coughing and sneezing. It can also spread when you are close to someone who is infected. And it can spread when you touch something that has the virus on it, such as a doorknob or a tabletop.
Coronaviruses are a large group of viruses. They cause the common cold. They also cause more serious illnesses like Middle East respiratory syndrome (MERS) and severe acute respiratory syndrome (SARS). COVID-19 is caused by a novel coronavirus. That means it's a new type that has not been seen in people before.
How is COVID-19 treated?
Mild illness can be treated at home, but more serious illness needs to be treated in the hospital. Treatment may include medicines to reduce symptoms, plus breathing support such as oxygen therapy or a ventilator. Other treatments, such as antiviral medicines, may help people who have COVID-19.
What can you do to protect yourself from COVID-19?
The best way to protect yourself from getting sick is to:
- Avoid areas where there is an outbreak.
- Avoid contact with people who may be infected.
- Avoid crowds and try to stay at least 6 feet away from other people.
- Wash your hands often, especially after you cough or sneeze. Use soap and water, and scrub for at least 20 seconds. If soap and water aren't available, use an alcohol-based hand sanitizer.
- Avoid touching your mouth, nose, and eyes.
What can you do to avoid spreading the virus to others?
To help avoid spreading the virus to others:
- Wash your hands often with soap or alcohol-based hand sanitizers.
- Cover your mouth with a tissue when you cough or sneeze. Then throw the tissue in the trash.
- Use a disinfectant to clean things that you touch often. These include doorknobs, remote controls, phones, and handles on your refrigerator and microwave. And don't forget countertops, tabletops, bathrooms, and computer keyboards.
- Wear a cloth face cover if you have to go to public areas.
If you know or suspect that you have COVID-19:
- Stay home. Don't go to school, work, or public areas. And don't use public transportation, ride-shares, or taxis unless you have no choice.
- Leave your home only if you need to get medical care or testing. But call the doctor's office first so they know you're coming. And wear a face cover.
- Limit contact with people in your home. If possible, stay in a separate bedroom and use a separate bathroom.
- Wear a face cover whenever you're around other people. It can help stop the spread of the virus when you cough or sneeze.
- Clean and disinfect your home every day. Use household cleaners and disinfectant wipes or sprays. Take special care to clean things that you grab with your hands.
- Self-isolate until it's safe to be around others again.
- If you have symptoms, it's safe when you haven't had a fever for 3 days and your symptoms have improved and it's been at least 10 days since your symptoms started.
- If you were exposed to the virus but don't have symptoms, it's safe to be around others 14 days after exposure.
- Talk to your doctor about whether you also need testing, especially if you have a weakened immune system.
