September 22. Delta is “by far” the world’s dominant coronavirus variant, a top World Health Organization scientist said Tuesday.
The global body downgraded its advisories on three other virus variants in a reflection of how delta is “outcompeting and replacing” everything else.
“Less than 1 percent of the sequences that are available right now are alpha, beta and gamma,” Maria Van Kerkhove, the WHO’s technical lead on covid-19, said in a video Q&A, referring to the three other variants the organization considers “of concern.”
The delta variant has appeared in 185 countries, as global coronavirus cases near 230 million and deaths surpass 4.7 million since the start of the pandemic.
The mu variant, which has been identified thousands of times in the United States and had raised concerns that it may be more resistant to vaccines than its sibling variants, is also being replaced in countries where delta is present, Van Kerkhove said. “Lambda and mu don’t seem to be dominant.”
