COVID-19 is caused by a coronavirus called SARS-CoV-2. 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.
HOW IT SPREADS
It is thought to spread mainly from person to person, mainly through respiratory droplets produced when an infected person coughs or sneezes. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs. Spread is more likely when people are in close contact with one another (within about 6 feet).
COVID-19 seems to be spreading easily and sustainably in the community (“community spread”) in any affected geographic areas. Community spread means people have been infected with the virus in an area, including some who are not sure how or where they became infected.
