The delta variant of Covid-19, now in 124 countries accounts for more than 75% of Covid cases in several countries including the US, Britain, Australia, India, Russia, etc.
“It is expected that it will rapidly outcompete other variants and become the dominant circulating lineage over the coming months,” the UN health agency said in its weekly epidemiological update.
The delta variant was first detected in India and this could be driven by multiple factors including relaxation of lockdown in various parts of India and Inequitable distribution of vaccines in India, the WHO said.
The US health official declared that the ‘variant of concern’ now accounts for about 83% of the covid cases in the US, which translates to a negative return on the massive vaccination drive.
According to WHO, 3.4 million new cases of Covid-19 were reported in the week to July 18 – a 12% increase from last week.
“At this rate, it is expected that the cumulative number of cases reported globally could exceed 200 million in the next three weeks,” said the WHO.
Meanwhile, other mutated variants of Covid-19 including Alpha, first detected in Britain, has been reported in 180 territories (up to six from last week), Beta, first detected in South Africa, in 130 (up to seven), and Gamma, first detected in Brazil, in 78 (up to three).
The countries with the highest number of cases include Indonesia with 350,273 new cases (up 44 percent) followed by Britain with 296,447 new cases (up 41 percent) and Brazil with 287,610 new cases (down 14 percent).
