The World Health Organization says the number of COVID-19 cases involving omicron is doubling every 1.5 to three days in countries where there is community transmission of the variant and not just people who were infected abroad.
Omicron’s “substantial growth advantage” over the delta variant means it is likely to soon overtake delta as the dominant form of the virus in countries where the new variant is spreading locally, the U.N. health agency said.
WHO noted that omicron is spreading rapidly even in countries with high vaccination rates or where a significant proportion of the population has recovered from COVID-1levels of population immunity It remains unclear if the rapid growth of omicron cases is because the variant evades existing immunity, is inherently more transmissible than previous variants, or a combination of both, WHO said.
Other major questions about omicron remain unanswered, including how effective each of the existing COVID-19 vaccines are against it. Conclusive data also does not exist yet on how ill omicron makes COVID-19 patients, the health agency said.
