WHO Says Delta Variant Accounts for 99% of Covid Cases Around the World – NBC 5 Dallas-Fort Worth

The delta variant, first detected in India a little less than a year ago, now represents 99% of sequenced Covid-19 cases globally, making it more prevalent than any other strain, officials from the World Health Organization said Tuesday.

Almost all of the up to 900,000 Covid cases sequenced worldwide over the last 60 days originated from the delta strain, Maria Van Kerkhove, the WHO’s technical lead on Covid, said during a Q&A streamed on the organization’s social media channels. Van Kerkhove’s comments come amid an international increase in Covid infections driven by surging cases in Europe. The continent accounted for roughly 60% of the more than 3.3 million new Covid cases in the world last week, Van Kerkhove said.

“Delta is really the dominant one,” Van Kerkhove said. “And there are two variants of interest – mu and lambda – that we’ve been tracking as well, but again, where delta is present, delta takes over.”
