Raging, a national shortage of test kits led to hours long waits at testing sites. rising cases led to massive workforce shortages and airline cancellations. businesses, including delta airlines on december 21st, called for shortening the recommended isolation period for the vaccinated who test positive six days later the cdc did just that, cutting the isolation time from 10 to 5 days. cdc director walensky said she was worried people would not stay home. >> people would feel well enough to be a...

Determined. arthel: meanwhile starting wednesday you can order up to four at home tests online at covid test.gov. they do not ship out until seven -- 12 days after youve ordered them not time but these tests, is it true some tests do not detect omicron until after youve already been contagious and possibly spreading the virus? >> is a variety of different kind of testers a pcr test which is most sensitive going to likely detected very, very early on but it takes a while to get those results i ca...

Available so in some ways this is a form of triage. let me show you the guidelines just to be clear what they are now telling people who are testing positive for covid. stay -- stay home for at least five days. your isolation can end if symptoms are gone or resolving. wear a mask around others for five more days but the new things they added to that, again, as you mentioned. optional antigen test around day five and if positive, isolate for -- for a full-ten days. that -- that -- it may not be d...

Could test positive even for weeks after. but the antigen test, the rapid at-home antigen test, usually thats a pretty good test for infectivity. so are you infectious at this point in time? so a lot of people could clear the virus after five or six days. what the uk has done, for example, is to say if you test negative twice on two consecutive days, you could end your isolation at seven days. thats the kind of policy that actually would have made more sense here in the u.s. too. >> so president...

Positive on a pcr test and negative on an antigen test? yes. the reason being the antigen test is more likely to be contagious with a virus in your nose and mouth? it depends on the question you are asking. if the question is, do i have a virus at all in my body? pcr test is the one for you? if the question is, am i contagious? then the antigen test. its a little newspapersed point, kate, i think its good if you can understand that. >> nuance, its good for everyone. good to see you, thank you so...

We actually dont know how our rapid tests perform and how well they predict whether youre transmissible at the end of disease. >> can we rely on them to find out if were positive or not? >> absolutely. unfortunately, i dont think it was founded in all of the science. the science says quite the opposite. when your antigen test is positive, youre very likely to have whats called culturable tests in your environment. i dont think thats accurate. >> what do you think dr. walensky got wrong? what don...

Before testing positive or two days before symptoms begin. then about three or four-days after symptoms begin. but fur asymptomatic and still test positive on a rapid antigen test, you can still spread to other people. now if you have no symptoms and you test positive on a pcr, the most accurate test, that is understandable. we expect a pcr test to remain positive for up to 90 days but not a rapid antigen. that is the key. that is the one that needs to be negative. carley: you know i think a lot...

This is giving another layer of protection to people who already have pretty good protection. thats good. thats important, but when you look at the numbers on the right side of the screen in terms of the hospitalizations in particular, those are primarily people who are unvaccinated completely, wolf. >> yeah, thats absolutely true. doctor, let me ask you about the new isolation guidance we have received from the cdc. you say it is -- and i am quoting you now, confusing and counterproductive, so ...

Our kids in classrooms. and i want to make sure we make the right decisions right now to do that. >> you heard what mayor-elect adams said about his plan for schools. and i know you think we should be doing everything to keep kids in schools you were just saying a few minutes ago. do you think the plan in new york is enough? for example in washington theyre requiring students to have negative tests before they show up for school next week. >> i think a negative test is fine. you know, if someone...
