The weekly epidemiological report from the UN health agency, released late on Tuesday, shows that the Omicron variant is increasingly dominant — making up nearly 97 per cent of all cases tallied by the international virus-tracking platform known as GISAID. Just over 3 per cent were of the Delta variant.
“The prevalence of the Omicron variant has increased globally and is now detected in almost all countries,” the WHO said.
“However, many of the countries which reported an early rise in the number of cases due to the Omicron variant have now reported a decline in the total number of new cases since the beginning of January 2022.”
All told, the WHO reported more than 19 million new cases of Covid-19 and under 68,000 new deaths during the week from January 31 to February 6. As with all such tallies, experts say such figures are believed to greatly underestimate the real toll.
Case counts fell in each of the WHO’s six regions except its eastern Mediterranean zone, which reported a 36 per cent jump, notably with increases in Afghanistan, Iran and Jordan.
In Europe, case counts fell 7 per cent — led by declines in places like France and Germany — even as countries in eastern Europe like Azerbaijan, Belarus and Russia posted increases.
In the Americas, case counts fell 36 per cent, with the United States — still the single most-affected country — reporting 1.87 million new cases, down 50 per cent from the previous week.
The WHO cited limited data about the effectiveness of vaccines against the Omicron variant, while saying estimates showed reduced protection of the first series of Covid-19 vaccines against the variant for severe disease, symptomatic disease and infection. Vaccines were most effective to prevent severe disease from Omicron.
The agency said booster doses increased estimates of vaccine effectiveness to over 75 per cent for all vaccines for which data were available, though the rates declined three to six months after injection.
It comes as the Actuaries Institute in Australia, released new data which says the surge in pandemic deaths since the reopening of borders and the so-called “let it rip” approach was adopted, will result in a 10 per cent rise in deaths, from all causes, across the country in January 2022.
The institute says that modelling suggests the number of lives lost in Australia in January 2022 will be higher than the total of virus-related deaths in 2020 and 2021 combined.
