COVID-19 Basics
COVID-19 (coronavirus disease 2019) is a disease caused by the SARS-CoV-2 virus. COVID-19 symptoms range can from mild to severe. Common symptoms of COVID-19 include fever, cough, shortness of breath, fatigue, muscle or body aches, headache, new loss of taste or smell, sore throat, or gastrointestinal symptoms. 

COVID-19 spreads when an infected person breathes out droplets and very small particles that contain the virus. These particles can be spread in one of three ways. 
1. Breathing in air when close to an infected person who is exhaling small droplets and particles that contain the virus. 
2. Having small droplets and particles that contain the virus land on the eyes, nose, or mouth, especially when an infected person sneezes or coughs. 
3. Touching the eyes, nose, or mouth with hands that have the virus on them.
