Covid delta variant to dominate within months: WHO – Times of India

Geneva: Highly contagious delta The type of COVID-19 is expected to become the dominant strain of the virus in the coming months, World Health Organization said on Wednesday.
The delta, which was first detected in India, is now recorded in 124 regions – 13 more than last week – and already accounts for more than three-quarters of sequenced samples in several major countries, WHO said.
“It is expected that it will increasingly compete with other variants and become the dominant circulating lineage in the coming months,” a the health agency said in its weekly epidemiological update.
Of the three other coronavirus cases (VOCs) of concern, alpha, first detected in the UK, has been reported in 180 regions (up six from last week), beta, first detected in South Africa, in 130 (up to seven) and gamma, first detected in Brazil at 78 (up three).
Delta prevalence has exceeded 75 percent in several countries, according to SARS-CoV-2 sequences submitted to the GISAID Global Science Initiative for four weeks to July 20.
These include Australia, Bangladesh, Botswana, UK, China, Denmark, India, Indonesia, Israel, Portugal, Russia, Singapore and South Africa.
“Growing evidence supports an increased transmission efficiency of the delta variant compared to non-VOC. However, the exact mechanism for the increase in transmission is unclear,” WHO said.
Overall, 3.4 million new Covid-19 cases were registered in the week to July 18 – up 12 percent from a week earlier, the Geneva-based organization said.
“At this rate, it is expected that the cumulative number of cases reported globally could exceed 200 million over the next three weeks,” the WHO said.
The organization said the global increase in transmission appears to be driven by four factors: the more transmissible version; relaxation of public health measures; There was an increase in the social mix and a larger number of non-vaccinated people.
Cases were up 30 percent in the WHO’s western Pacific region and 21 percent in its European region.
The highest number of new cases were reported from Indonesia (3,50,273 new cases; up 44 per cent), the UK (2,96,447 new cases; up 41 per cent), and Brazil (2,87,610 new cases; down 14 per cent). )
However, the number of weekly deaths remained steady at 57,000 as of last week and after a steady decline for more than two months.
