Current Understanding of COVID-19
Anyone can have mild to severe symptoms. Older adults and people who have severe underlying medical conditions like heart or lung disease or diabetes seem to be at higher risk for developing more serious complications from COVID-19 illness.
Watch for symptoms: People with COVID-19 have had a wide range of symptoms reported – ranging from mild symptoms to severe illness. Symptoms may appear 2-14 days after exposure to the virus. People with these symptoms may have COVID-19:
- Fever or chills
- Shortness of breath or difficulty breathing
- Muscle or body aches
- New loss of taste or smell
- Sore throat
- Congestion or runny nose
- Nausea or vomiting
This list does not include all possible symptoms. CDC will continue to update this list as we learn more about COVID-19.
What is Isolation?
Isolation is for people who are already sick. It separates sick people with a contagious disease from people who are not sick.
What is Quarantine?
Quarantine is for people who are not sick, but may have been exposed. It separates and restricts the movement of people who were exposed to a contagious disease to see if they become sick.
