People are no longer considered infectious (able to spread the virus that causes COVID-19) after 10 days have passed since they became infected.". And research done by the CDC shows about half of people were still testing positive on the antigen test between five and nine days after symptom onset or diagnosis. Scientists can determine that by taking samples from someone who's been infected and trying to grow the virus in a lab what's known as a viral culture. The Biden administration is buying a billion rapid antigen tests to ship to American homes, aiming to address the need for increased Covid testing and ease a nationwide shortage of tests. The agency has defended its decision not to require testing to end quarantine, saying antigen tests have not yet been proven a good indicator of contagiousness after five days of infection and arguing people are much less likely to spread the virus after that period, especially while wearing a mask.

The current CDC guidelines place little emphasis on the need for a negative test to exit isolation, said Michael Mina, MD, PhD, Chief Science Officer of eMed and one of the papers co-authors. They are capable of detecting tiny bits and pieces of the viruss genetic material by copying whatever is floating around in a persons sample over and over, amplifying it a million- to a trillion-fold, said Dr. Marie Louise Landry, director of the Clinical Virology Laboratory at Yale New Haven Hospital.

But with Omicron, were potentially seeing earlier symptoms even before the peak virus load has been reached which starts the isolation clock several days earlier and leaves more people contagious on days six to 10.. The confusion around how to interpret test results stems largely from this conundrum: While there is a wealth of testing options available, there is no foolproof way to gauge whether a person is actually infectious.
