Dr. Wacther says this is why some CDC guidelines are 'incredibly tricky.' While in some cases those guidelines say you can return to work in five days, he says at that point, there's a 20% chance you're still infectious - plus the possibility of false negatives for omicron if you test too early.
SAN FRANCISCO -- Amid the omicron-led coronavirus surge, UCSF Chair of the Department of Medicine, Dr. Bob Wachter, joined ABC7 News on our 3 p.m. program"Getting Answers," to discuss issues related to hospitals, schools and more.
Testing is a common thread in all of these topics, as there is still uncertainty about the accuracy of at-home COVID-19 tests and CDC recommendations. The CDC recently released new guidelines Dr. Wachter says are"tricky," and don't"make a lot of sense."His son recently tested positive for coronavirus, but not right away. Despite"absolutely having symptoms," his son tested negative on day one.This is something Dr. Wachter says has been a trend with the omicron variant - People are getting false negatives in the early stages of infection.
His son retested on day five and was positive. For the second test, Dr. Wachter used a different technique, based on new data.That data suggestsWhile Wachter admits it's"gross," you can swab around the back of the throat for about 30 seconds, and then put the same swab in your nose, as instructed by the test, to possibly garner a more accurate result.He assures that the at-home tests are still 95-percent sensitive in detecting omicron, even without the throat swab.
