Prime News, International and National, Health, Disease, Geneva (Switzerland), May 13:- The World Health Organisation (WHO) has said a recent risk assessment of the situation in India found that “resurgence and acceleration” of COVID-19 transmission in the country had several potential contributing factors, including “several religious and political mass gathering events which increased social mixing.”
The WHO, in its COVID-19 Weekly Epidemiological Update, published Wednesday (May 12), said that viruses in the B.1.617 lineage were first reported in India in October 2020.
“A recent risk assessment of the situation in India conducted by WHO found that resurgence and acceleration of COVID-19 transmission in India had several potential contributing factors, including an increase in the proportion of cases of SARS-CoV-2 variants with potentially increased transmissibility; several religious and political mass gathering events which increased social mixing; and, underuse of and reduced adherence to public health and social measures (PHSM). The exact contributions of each of these factors on increased transmission in India are not well understood,” it said.
The update said that approximately 0.1% of positive samples in India have been sequenced and uploaded to GISAID to identify SARS-CoV-2 variants. GISAID enables rapid and open access to epidemic and pandemic virus data.
The WHO update said that “the prevalence of several VOCs including B.1.1.7 and B.1.612 sublineages increased concurrently to the surge in COVID-19 cases reported in India.”
“Since the identification of these variants through late April 2021, B.1.617.1 and B.1.617.2 accounted for 21% and 7% of sequenced samples from India,” the update said, adding that preliminary analyses conducted by WHO using sequences submitted to GISAID suggests that B.1.617.1 and B.1.617.2 have a substantially higher growth rate than other circulating variants in India, suggesting potential increased transmissibility compared.
The update said that outside of India, the United Kingdom has reported the largest number of cases sequenced as B.1.617 sub-lineages, and recently designated B.1.617.2 as a “national variant of concern.”
Giving a global overview of the COVID-19 situation, the update said that the number of new COVID-19 cases and deaths globally decreased slightly this week, with over 5.5 million cases and over 90,000 deaths. (MR, Inputs: Agencies)
