Last, for some case-patients, virus was not isolated in samples collected at the time of diagnosis. With earlier variants, people became contagious two to four days after infection. Duration of Infectious Virus Shedding by SARS-CoV-2 Omicron VariantInfected Vaccinees. Figure 2. A couple of years is a long time for highly contagious respiratoryviruses, andSARS-CoV-2(thevirusthat causes COVID-19) has been no different. People who are up to date on their COVID-19 shotsprobably don't shed as much virus for as long, so they're also less likely to pass it on, he added.

The newer boosters, which take aim at both the original virus and the BA.4/BA.5 variantscommon this summer, are more protective against XBB.1.5 than earlier boosters. At the same time, the virus itself is spreading faster with the now-dominant strains, leading to more upper respiratory symptoms, Arwady said.
