f you have COVID-19, you can spread the virus to others. There are precautions you can take to prevent spreading it to others: isolation, masking, and avoiding contact with people who are at high risk of getting very sick. Isolation is used to separate people with confirmed or suspected COVID-19 from those without COVID-19.
These recommendations do not change based on COVID-19 Community Levels. If you have COVID-19, also see additional information on treatments that may be available to you.
This information is intended for a general audience. Healthcare professionals should see Ending Isolation and Precautions for People with COVID-19. This CDC guidance is meant to supplement—not replace—any federal, state, local, territorial, or tribal health and safety laws, rules, and regulations.
If you test positive for COVID-19, stay home for at least 5 days and isolate from others in your home.
You are likely most infectious during these first 5 days.
- Wear a high-quality mask if you must be around others at home and in public.
- Do not go places where you are unable to wear a mask. For travel guidance, see CDC’s Travel webpage.
- Do not travel.
- Stay home and separate from others as much as possible.
- Use a separate bathroom, if possible.
- Take steps to improve ventilation at home, if possible.
- Don’t share personal household items, like cups, towels, and utensils.
- Monitor your symptoms. If you have an emergency warning sign (like trouble breathing), seek emergency medical care immediately.
