It's not yet clear, but some early data suggests people with omicron might become contagious sooner than with earlier COVID variants.
It's not yet clear, but some early data suggests people might become contagious sooner than with earlier variants - possibly within a day after infection.
That's because omicron appears to cause symptoms faster than previous variants - 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. Researchers say it's 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.
"A lot of people are turning positive by day three," Karger says, referring to omicron."There's basically an opportunity here to catch people earlier than you would with the other variants."People who have COVID-19 symptoms should get tested immediately if possible.
