Ontario appears to be incubating its very own COVID-19 Omicron subvariant, with 996 cases found so far
Public Health Ontario says the new subvariant “has been increasingly co-circulating primarily in Ontario and in some American states,” according to a report quietly published on Monday.
“At this time, the impact of these mutations on transmission, risk of severe disease, reinfection and breakthrough infection is unknown,” Public Health Ontario scientists wrote in their report released earlier this week.of BA.2.20 cases found to date suggested that there could be up to a 24 per cent growth advantage associated with the new subvariant over the dominant BA.2 strain, but they assessed that finding with a low degree of confidence.
Eighty-five per cent of known cases involved people who received two or three doses of COVID-19 vaccine.
