The omicron variant lasted 193.5 hours. Like the other 200 or so respiratory viruses we know of, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the new coronavirus, infects the . Omicron could still be detected 193 hours - eight days - after it was applied. Fomite transmission is difficult to prove definitively, in part because respiratory transmission from asymptomatic people cannot be ruled out 3, 4, 5. "This might affect the balance of transmission routes favouring more fomite transmission than we saw before," she said. Another possible influence may have been the fluid that the researchers used to prepare the skin samples on which they assessed Omicrons presence.

The World Health Organization advises COVID transmission mainly occurs during close personal contact and via aerosols in poorly ventilated or crowded spaces. The researchers said Omicron took 193.5 hours - the equivalent of eight days - to manifest. The air is the issue and we should be laser-focused on that rather than be distracted with surfaces.. But Marr stressed the study's conditions don't reflect real-world scenarios. Those viral particles are sort of hanging in the air.. How long can Omicron strain survive on different surfaces? What you can do. This includes cleaning . Its also worth noting the study was completed under highly controlled laboratory conditions. There's still a lot we don't know about how the Omicron variety spreads. The study has yielded interesting results, but has limitations that mean understanding the significance of these findings to the real world is difficult. On the plus side, researchers used the same set of conditions when assessing all variants so comparisons of survival times are likely to be a good indicator of relative environmental stability. Everyone Practices Cancel Culture | Opinion, Deplatforming Free Speech is Dangerous | Opinion. More than 95 percent of the virus was gone from the stainless steel surface after 24 hours. In a well-known study, published in the New England Journal of Medicine (NEJM), researchers compared how long two coronaviruses could survive on a handful of surfaces.
