According to the CDC, COVID-19 has an incubation period of 2-14 days, meaning that is how long it takes for the virus to become present in your system after you were first exposed. Now that more people have received COVID vaccines, scientists are able to study the different incubation periods between people who are non-vaccinated, people who have had 1-2 vaccine doses, and 3 doses. As of January 2021, it is recommended to be tested 5 days after exposure. If you are tested too soon, your viral load may not be high enough to be detected by the test.
