Common symptoms of COVID-19 include:
- Fever or chills

How COVID-19 Spreads
COVID-19 spreads primarily through respiratory droplets released when an infected person coughs, sneezes, talks, sings, or breathes. These droplets can travel up to 6 feet and land in the mouths or noses of people nearby.
The virus can also spread through contact with contaminated surfaces, such as doorknobs, tables, or phones. If you touch a contaminated surface and then touch your eyes, nose, or mouth, you can become infected.
Precautions to Prevent COVID-19
To protect yourself and others from COVID-19, follow these precautions:
1. Get Vaccinated and Boosted:
- Vaccination remains the most effective way to prevent severe illness, hospitalization, and death from COVID-19.
- Booster doses provide additional protection and increase the duration of immunity.
2. Wear a Mask:
- Wearing a well-fitting mask in public indoor settings, especially where social distancing is difficult, is essential for reducing transmission.
- Masks help to prevent the spread of respiratory droplets.
3. Maintain Physical Distance:
- Try to maintain at least 6 feet of distance from others, especially indoors.
4. Wash Your Hands Frequently:
- Wash your hands thoroughly with soap and water for at least 20 seconds.
- If soap and water are not available, use an alcohol-based hand sanitizer with at least 60% alcohol.
5. Clean and Disinfect Surfaces:
- Regularly clean and disinfect frequently touched surfaces, such as doorknobs, light switches, and countertops.
6. Stay Home When You Are Sick:
- If you are sick, stay home to avoid spreading the virus to others.
- Isolate yourself from others as much as possible.
7. Get Tested:
- Get tested for COVID-19 if you have symptoms or if you have been in close contact with someone who tested positive.
8. Seek Medical Attention if Needed:
- If you experience severe symptoms of COVID-19, seek immediate medical attention.
By following these precautions, you can help protect yourself and your community from COVID-19.
