The highly contagious Delta variant of COVID-19 is expected to become the virus's dominant strain in the coming months, according to the World Health Organization on Wednesday.

Delta, which was discovered in India, has now been recorded in 124 territories – 13 more than the previous week – and accounts for more than three-quarters of sequenced specimens in many major countries, according to the WHO.

"It is expected that it will quickly outcompete other variants and become the dominant circulating lineage in the coming months," the UN health agency said in its weekly epidemiological update.

Alpha, the first coronavirus variant of concern (VOC), has been reported in 180 territories (up six from last week), Beta, first detected in South Africa, in 130 (up seven), and Gamma, first detected in Brazil, in 78. (up three).

According to SARS-CoV-2 sequences submitted to the GISAID global science initiative in the four weeks leading up to July 20, Delta prevalence exceeded 75% in several countries.

Australia, Bangladesh, Botswana, the United Kingdom, China, Denmark, India, Indonesia, Israel, Portugal, Russia, Singapore, and South Africa were among them.

"Growing evidence suggests that the Delta variant is more transmissible than non-VOCs. However, the precise mechanism underlying the increased transmissibility is unknown "according to the WHO

 

Cases are up 12%.

According to the Geneva-based organisation, 3.4 million new COVID-19 cases were reported in the week ending July 18, a 12% increase from the previous week.

"At this rate, the total number of cases reported globally in the next three weeks is expected to exceed 200 million," the WHO said.

According to the organisation, global increases in transmission appeared to be caused by four factors: more transmissible variants, relaxation of public health measures, increased social mixing, and a large number of unvaccinated people.

Cases increased by 30% in the WHO's Western Pacific region and by 21% in its European region.

The countries with the highest number of new cases were Indonesia (350,273 new cases; a 44 percent increase), the United Kingdom (296,447 new cases; a 41 percent increase), and Brazil (287,610 new cases; down 14 percent).

The number of weekly deaths, on the other hand, remained stable at 57,000, similar to the previous week and following a two-month decline.
