The number of Covid-19 cases continues to increase in 4 regions of the World Health Organization (WHO): Eastern Mediterranean, Southeast Asia, Europe, Western Pacific. More than half of the world’s Covid-19 cases are BA.5 Omicron.
According to the weekly epidemiological report that the WHO just sent to news agencies on the morning of 7-7 am (Vietnam time), an additional 4.6 million cases of HIV were reported worldwide in the last statistical week (from June 27 to July 3). Covid-19 registered. † According to WHO Director-General Tedros Adhanom Ghebreyesus, the number of global Covid-19 cases has increased by almost 30% in just two weeks.
The number of cases continued to increase during the week in 4/6 WHO regions, the highest in the Eastern Mediterranean, with a rise of 29%.
Notably, while the global overall death rate fell 12% this week, the eastern Mediterranean death rate rose 34%. This is one of the areas where the WHO has always raised concerns because the vaccination rate is very low, as of April 2022 only 42% of the population has received the full basic dose (2 doses).
The number of cases in Southeast Asia (WHO Southeast Asia does not include Vietnam) increased by 20%, the death rate increased by 16%, this is also an area with many countries with low vaccination rates. Europe continued to increase 15% in new cases over the week and accounted for 52% of the total number of cases worldwide.
The western Pacific region to which Vietnam belongs witnessed a turnaround: last week it fell slightly, this week the number of cases increased by 4%, but the number of deaths decreased by 12%.
The Americas region saw an 18% decrease in morbidity and a 13% decrease in mortality; while Africa seems to have passed the peak of the epidemic with a 33% decrease in morbidity and a 50% decrease in mortality.
As for the ratio of subvariants/subvariants, the WHO has changed the statistical method: Omicron subvariant is separated, statistically equal to Delta and unspecified strains instead of being counted as “children” of Omicron.
According to this new statistical way, the BA.5 Omicron subvariant has been shown to have officially become the “dominant” species worldwide, with a rate skyrocketing from 37% to 52% on the number of gene sequences synthesized in the GISAID database.
BA.4 rates rose slightly from 11% to 12% globally; while BA.2.12.1 fell from 19% to 11%. BA.2 was the “dominant” line a few weeks ago and now represents only 9% of the world.
All told, 92% of global cases are due to Omicron mutations, 0.01% to Delta, with the rest being further identified, possibly Omicron, Delta, or other recombinant forms.
The WHO director-general said the organization is also closely monitoring the new strain BA.2.75, which was reported from India a few days ago.
