review of 64 studies and more than 24,000 testing samples, rapid antigen tests managed to detect COVID-19 in 72% of symptomatic COVID-19 cases pre-omicron. In positive people without symptoms, they were only about 58% accurate. On the other hand, PCR tests are generallyto be around 98% accurate at detecting COVID-19 infections when used correctly.
The omicron variant has over 50 mutations from the original virus, including more than 30 on its spike protein, which helps the virus enter our cells,. Many antibodies we generate from vaccination and infection target these spike proteins—so when they change, it can make immunity and antibody treatments less effective.

Fauci says omicron variant is `just raging around the world'The COVID-19 omicron variant is “just raging around the world,” the White House's top medical adviser said Sunday as President Joe Biden prepares to issue “a stark warning of what the winter will look like” for unvaccinated Americans. Dr. Anthony Fauci, the country's leading infectious disease expert, told NBC’s “Meet the Press” that “the real problem” for the U.S. hospital system is that “we have so many people in this country who are eligible to be vaccinated who have not yet been vaccinated.” The prospect of a winter chilled by a wave of coronavirus infections is a severe reversal from the optimism projected by Biden some 10 months ago, when he suggested at a CNN town hall that the country would essentially be back to normal by this Christmas.
