It also increases the quality and quantity of local water supplies and provides myriad other environmental, economic, and health benefitsoften in nature-starved urban areas. Rapid antigen tests are not as accurate as PCRs, which are handled in a lab, but they have several advantages: they are faster, cheaper, can be done at home and have proven sufficiently sensitive when the person has a higher viral load and is therefore more contagious (although the spread of the omicron variant is complicating this picture). That's especially the case if you're fully vaccinated, symptoms have resolved and you continue to practice masking. Alternatively, as University of Bern computational epidemiologistChristian Althausnotedon Twitter, the surge in cases might also be explained if the variant can evade immunity from prior infection or vaccination or it could be somecombinationof immune evasion and a bump up in contagiousness. What we need to do is to see whether the throat swab could provide more sensitivity..

Bhattacharya said the closest test case for whether a booster would help with omicron is with the beta variant, which shares some similarity with the newer variant. Otherwise, isolation should be extended to 10 days. We have always known antigen tests have lower sensitivity than molecular tests. While 58.2% of the U.S. population is fully vaccinated, and many are getting booster shots, vaccination rates ranged from 26.5% in Lesotho to 3.1% in Malawi, according to statistics gathered by .

Although the researchers only tested BinaxNOW kits, none of the at-home rapid antigen tests available over the counter in the U.S. are designed for throat swabs. However, protection estimates greater than 90% might be too high if individuals with a previous infection were more likely than those without one to come forward for a test for reasons other than suspicion of COVID-19. The citys already pulled up about four million square feet of grass on public property so far this year, because thirsty green parkways are something they just cant afford anymore.
