SARS-CoV-2 is the virus that causes COVID-19, the disease.
Spread:
Thought to mainly occur from person-to-person contact (within about 6 feet) through
respiratory droplets when an infected person coughs or sneezes (similar to influenza
and other respiratory viruses).
People are most contagious when most symptomatic (sickest). • Spread may be possible
when a person touches a contaminated object and then touches their own mouth, nose,
or their eyes, but this is not the main way.
Might be possible for people to spread before symptoms occur, but less likely.
Symptoms
Symptoms typically appear 2 to 14 days after exposure (usually 5 days).
Symptoms include fever, cough, or shortness of breath; occasionally sore throat, diarrhea,
and general malaise.
Older adults and people with preexisting conditions are most at risk for severe illness.
• Fatality rates estimated at 2.5-3% overall, primarily in older adults and people
with pre-existing medical conditions.
Note 97-98% of people recover, and ~ 80% have only a mild illness.
The fatality rate in people with no other medical conditions is <1%.
The fatality rate is lowest in people ≤ age 30.
Prevention of spread (applies to ANY viral illness)
Avoid close contact with people who are sick.
Avoid touching your eyes, nose, and mouth.
Stay home when you are sick.
Cover your cough or sneeze with a tissue, then throw the tissue in the trash.
Clean and disinfect frequently touched objects and surfaces using a regular household
cleaning spray or wipe.
Wash your hands often with soap and water for at least 20 seconds, especially after
going to the bathroom; before eating; and after blowing your nose, coughing, or sneezing.
If soap and water are not readily available, use an alcohol-based hand sanitizer with
at least 60% alcohol.
Follow CDC’s recommendations for using a facemask.
Facemasks should be used by people who show symptoms of COVID-19 to help prevent the
spread of the disease to others. The use of facemasks is also crucial for health workers
and people who are taking care of someone in close settings at home or in a health
care facility.
