5 things to know about the need for ongoing COVID-19 testing

As more and more people get vaccinated, testing has also been dropping. Testing plays an important role in stopping the spread, even if you are vaccinated. There are many tests being administered. One is diagnostic which means it detects when the virus is actually present in a sample. Think PCR tests, so a nasal swab or a saliva test. The other is antigen testing. This type detects when certain proteins are present on the surface of the virus. Both tests are helpful and beneficial. The CDC says that if you are fully vaccinated and show no symptoms, you do not need to be tested.
