A positive viral test result means that the test detected SARS-CoV-2, the virus that causes COVID-19, at the time of testing, and that the individual most likely has a current infection and may be able to transmit the virus to others. A negative test result means the test did not detect SARS-CoV-2 at the time of testing. However, a negative test does not mean the employee does not have any virus, or will not later get the virus. It means only that the virus causing SARS-CoV-2 was not detected by the test.
