A file 15 million new Covid-19 infections had been reported throughout the globe in a single week as omicron quickly replaces delta because the dominant variant throughout the globe, and “we all know that is an underestimate,” World Well being Group Director-Normal Dr. Tedros Adhanom Ghebreyesus informed reporters at a press briefing Wednesday.

Amongst greater than 357,000 instances sequenced within the final 30 days, practically 59% had been omicron, the WHO mentioned within the epidemiological report. The WHO, the United Nations’ well being group, cautioned that the info might not totally present how far omicron has unfold resulting from reporting delays and limits sequencing in some nations.

In response to the report, omicron has a shorter doubling time than different variants, which means the variety of days it takes for instances to double, and it could extra readily evade prior immunity, permitting it a bonus over different variants.

Whereas omicron has appeared to tear via populations the place it was detected early after which drop right down to decrease ranges, Van Kerkhove mentioned delta had an identical trajectory at its peak, however by no means peaked at such ranges as omicron.

However, she emphasised, the path of omicron can nonetheless be influenced by the world’s actions, together with vaccination and taking steps to attenuate unfold.

“There is no such thing as a inevitability about this virus and the way it circulates,” she mentioned. “We now have management, some measure of management, by way of limiting its unfold with instruments that we have now entry to: masks, distancing, air flow, avoiding crowds.”

Van Kerkhove mentioned the WHO expects the virus will proceed to evolve to turn into fitter and both kind of extreme, that there’ll proceed to be outbreaks of illness among the many unvaccinated and that as totally different populations combine, outbreaks of different viruses will typically happen similtaneously these of Covid.

“The virus is effectively on its approach to turning into endemic,” Van Kerkhove mentioned. “However we’
