The World Health Organisation (WHO) said on Wednesday, 12 May, that the COVID-19 variant responsible for the surge in India's COVID outbreak has been found in as many as 44 countries across the world.
In its weekly epidemiological update on the pandemic, the UN health agency said, "WHO has received reports of detections from five additional countries.”
After India, Britain has reported the largest number of COVID cases caused by the variant.
Earlier this week, the WHO declared B.1.617 as a "variant of concern", news agency AFP reported. The variant counts three so-called sub-lineages with slightly different mutations and characteristics.
The Britain, Brazil, and South Africa variants are seen as more grievous than the original version of the virus because they are either more transmissible, deadly or able to get past some vaccine protections.
WHO also pointed to "preliminary evidence" that the variant was more resistant to treatment with the monoclonal antibody Bamlanivimab, and also highlighted early lab studies indicating "limited reduction in neutralisation by antibodies", AFP reported.
However, it stressed that "real-world impacts" on the effectiveness of vaccines against the variant for instance "may be limited".
India, with a population of 1.38 billion people, is the world's second-most infected country after the United States with nearly 23 million COVID-19 cases, and is currently recording more than 3,00,000 new cases and close to 4,000 deaths per day.
WHO said the spread of B.1.617, alongside other more transmittable variants, seems to be one of several factors increasing India's explosive surge in new cases and deaths.
WHO further found that, “resurgence and acceleration of COVID-19 transmission in India had several potential contributing factors, including increase in the proportion of cases of SARS-CoV-2 variants with potentially increased transmissibility”.
WHO added that so far only 0.1 percent of COVID tests in India had been genetically sequenced and uploaded to the GISAID database to identify the variant in question.
By the end of April, B.1.617.1 and B.1.617.2 accounted for 21 and seven percent respectively of all sequenced samples from India, it said.
The B.1.1.7 variant, which was first detected in Britain, is another more contagious variant also spreading across the country.
