Researchers cautioned that because Omicron is far more transmissible, its lower hospitalization rate will likely be offset by soaring COVID-19 case numbers as the wave of infections builds The new system will extrapolate numbers from a statistically significant sample, rather than rely on daily . Omicron, the SARS-CoV-2 variant responsible for a cluster of cases in South Africa and that is now spreading around the world, is the most heavily mutated variant to emerge so far and carries mutations similar to changes seen in previous variants of concern associated with enhanced transmissibility and partial resistance to vaccine induced immunity. Even with breakthrough infections doctors say the risk of being hospitalized from omicron is much lower with vaccines and a booster. A combination of factors, including misinformation that the pandemic is over, the lifting of mask mandates, ending physical distancing - and a more transmissible Omicron BA.2 variant - are causing an increase of COVID-19 cases globally, the World Health Organization warned on Wednesday. Boosters: Kids 5-11 could start receiving 3rd doses of Pfizer's COVID-19 vaccine within days The new subvariant appears to be about more 25% transmissible, though early data shows it isn't any more likely to cause severe illness than other subvariants or the original omicron variant, state epidemiologist Rachel Herlihy said during a Thursday morning news conference.

New, highly transmissible forms of omicron may pose latest covid threat. Experts continue to worry that the omicron coronavirus variant may be more transmissible than delta, which would be a troubling new turn for the COVID-19 pandemic. Now, two studies show that the variant has achieved success despite causing viral levels in the body that are similar to — or lower than — those of its main competitor, the Delta variant 1, 2.
