When am I contagious if infected with omicron?
It바카라 게임 웹사이트s not yet clear, but some early data suggests people might become contagious sooner than with earlier variants 바카라 게임 웹사이트 possibly within a day after infection.
The U.S. Centers for Disease Control and Prevention says people with the coronavirus are most infectious in the few days before and after symptoms develop. But that window of time might happen earlier with omicron, according to some outside experts.
That바카라 게임 웹사이트s because omicron appears to cause symptoms faster than previous variants 바카라 게임 웹사이트 about three days after infection, on average, according to preliminary studies. Based on previous data, that means people with omicron could start becoming contagious as soon as a day after infection.
With previous variants, people became contagious two to four days after infection. And people remain contagious a couple days after symptoms subside.
Researchers say it바카라 게임 웹사이트s too early to know whether that shorter incubation period for omicron translates into earlier contagiousness. But it would help explain the variant's rapid spread.
Dr. Amy Karger of the University of Minnesota Medical School recommends that people test themselves at three days and five days after exposure if possible.
"A lot of people are turning positive by day three,바카라 게임 웹사이트 Karger says, referring to omicron. 바카라 게임 웹사이트There바카라 게임 웹사이트s basically an opportunity here to catch people earlier than you would with the other variants.바카라 게임 웹사이트

If you only have one test, it's fine to wait until day five, Karger says.
People who have COVID-19 symptoms should get tested immediately if possible.
Lab-developed tests are more sensitive than rapid tests so they should be able to pick up the virus by day three after exposure, if not earlier.
People who don바카라 게임 웹사이트t develop symptoms generally have much lower viral levels, so it바카라 게임 웹사이트s far less clear when or if they become infectious.
Still, those who test positive but don바카라 게임 웹사이트t have symptoms should isolate for at least five days, under the . The agency came under criticism for not requiring a negative test before leaving isolation, but even after tweaking the guidelines officials said that step should be optional.
People with symptoms should stay isolated until they have been fever-free for at least 24 hours.
