Of 15,000 virus sequences, 11% comprise variants from the UK, South Africa, and Brazil; UK strain dominant in India | India News
NEW DELHI: With six variants Of concern (COV) of the coronavirus dominating the global topography today, India is grappling with three particular variants, namely the UK, Brazil and South Africa, since the second wave Covid-19 hit the country. Lineages B.1.1.7 (called UK variant), B.1.351 (South African variant), and P.1 (Brazil variant) have been detected in India.
Last year when the virus broke out panindian, Maharashtra it was hard hit with the majority of reported cases, of which nearly 20 percent of the cases showed the ‘double mutant’ trace, an Indian variant called the B.1.617 lineage.
The VOC of the B.1.1.7 lineage (UK variant) with higher transmission capacity can be seen in Delhi. In the second week of March in Delhi, 28 percent of the samples had the UK variant and in the fourth week of March the percentage increased to 50 percent. National Center for Disease Control (NCDC) reveal the data.
However, in West Bengal, destined for the survey, all VOCs were detected. Principal Virologist Dr. Shahid Jameel said: “In the last report, of approximately 15,000 virus sequences, 11 percent is made up of these VOCs. Among these, B.1.1.7 dominates in India and B.1.351 is mainly found in West Bengal.
So far, only 2 or 3 P.1 VOCs have been detected. “An Indian variant lineage B.1.617 (also called double mutant and first
seen in Maharashtra) has now spread to many other states. “For example, it only comprised about 2% of the footage from Maharashtra in January, but it increased to about 15% in February and about 35% in March. Some other studies find that its frequency is around 60% in Maharashtra. , “explains Jameel.
Variant B.1.1.7 dominates Punjab with more than 80 percent of viruses belonging to this lineage.
For the state of West Bengal that has all the VOCs, Jameel said, “West Bengal has all the VOCs plus B.1.617 with a frequency of around 10 percent. This is an area to watch closely due to the prolonged elections. and packed rallies. ”
Apart from viral lineages, several mutant viruses are circulating in the country with different frequencies.
When asked about vaccination, Dr. Jameel said: “The penetration of our vaccine is very low at the population level. To date, only 1.5 percent of people have received both doses of the vaccine and 8.5 percent have received a dose. ”
In addition, he stated: “Variant viruses have contributed to this increase.
These variants are more infectious and sometimes lead to partial evasion of immune responses, leading to reinfection or progressive infections. ”
INSACOG, which brings together 10 different national laboratories to promote genome sequencing and surveillance, was notified in mid-January and began operating in mid-February.
Dr. Jameel says: “In this time he has provided around 20,000 sequences, which is about 1 percent of confirmed cases. This has allowed us to know which viruses are spreading in the community and, more importantly, which could be of concern in the future. ”
However, the virologist demands that more effort be required, that more laboratories be incorporated, and more funds provided to increase activities. According to NCDC data, INSACOG has sequenced 15,135 samples.
to date 1,735 VOCs were found. Pan India, the figures as of now stand at 1,644 cases of the UK variant, 112 of the South African variant and 732 of the Indian variant B.1.617 (double mutation).
India is in the midst of a terrible medical crisis, facing a creaking of hospital beds and oxygen. India continues to report close to 3.5 lakh of covid cases each day with today’s latest official figures at 3,49,691 new covid cases, 2,767 deaths and 2,17,113 discharges in the last 24 hours, according to the Union Ministry of Health. .
