According to the World Health Organization (WHO), the Omicron coronavirus strain has been detected in 89 countries, with the number of cases doubling every 1.5 to 3 days in places with community transmission. The WHO said in an update that Omicron is spreading rapidly in nations with high levels of population immunity, but it's unclear if this is due to the virus' capacity to circumvent protection, its intrinsic greater transmissibility, or a mix of both. Omicron was recognised as a variant of concern by the CDC on Nov. 26, shortly after it was discovered, and little is known about it, including the severity of the sickness it produces. The WHO stated, “There is still limited data on the clinical severity of Omicron. More data are needed to understand the severity profile and how severity is impacted by vaccination and pre-existing immunity.” There are still limited available data, and no peer-reviewed evidence, on vaccine efficacy or effectiveness to date for Omicron,” the statement continued. The WHO has cautioned that as the number of patients rises, hospitals may become overburdened in some areas.
