Similar to other infectious diseases, COVID-19 spreads mainly from person to person. If someone is infected with coronavirus, respiratory droplets from their sneezes or coughs can spread, making other people around them sick, too.  If an infected person is coughing or sneezing near you, you might get the virus from them. However, you might not get sick immediately. The incubation period for COVID-19 is about two to 14 days,  according to the CDC. This means it can take anywhere from two to 14 days from the time you caught the virus for you to feel sick. This is known as being pre-symptomatic. Additionally, some people are asymptomatic carriers — those who become infected with the virus but never have symptoms. Because of this, asymptomatic carriers can spread the virus without even knowing they have it.
