Nearly 90 pc Covid samples genome-sequenced in Delhi in July-August detected with BA.2 variant
In August, 2,064 samples were analysed and 90.35 per cent of those were detected with the BA.2 variant, while 199 samples were detected with the BA.5 variant. No sample was detected with the BA.4 variant. Delhi witnessed a spike in the number Covid cases in August, with experts attributing it to people letting their guard down and not following Covid-appropriate behaviour.
BA.4.6: What we know about the new Omicron subvariant that is spreading
BA.4.6 is a descendant of the BA.4 variant, which was first detected in January 2022 . It's possible it could be a recombinant variant.
Another new COVID variant is spreading - here's what we know about omicron BA.4.6
The latest briefing document on COVID variants from the UK Health Security Agency (UKHSA) noted that during the week beginning August 14, BA.4.6 accounted for 3.3 per cent of samples in the UK. It has since grown to make up around 9 per cent of sequenced cases. Similarly, according to the Centres for Disease Control and Prevention, BA.4.6 now accounts for more than 9 per cent of recent cases across the US. The variant has also been identified in several other countries around the world.
What is the BA.5 variant and why does it seem to be reinfecting so many people with COVID-19?
BA.5 is a sister variant of the Omicron strain that has been dominant worldwide since the end of 2021, and has already caused spikes in case rates - even with reduced testing - in countries including South Africa, where it was first found, as well as the United Kingdom, parts of Europe, and Australia.
BA.5 sub-variant can re-infect you with Covid 'within weeks': Experts
That means even if you were infected in 2020 with Delta or even Omicron BA.1 last winter, you can still get BA.5. Your previous immunity does not protect you from the latest strain.
420 new Covid cases, 1 more death in Delhi; positivity rate 5.25%
The number of active cases in Delhi stands at 2,938, down from 3,268 a day ago. As many as 2,348 patients are under home isolation, it said. There are 364 containment zones in Delhi, it added. Delhi has reported a few cases of BA.4 and BA.5 variants of Omicron, which are highly transmissible, but experts have said there is no need to panic as they don't cause severe infection.
BA.4, BA.5 subvariants causing COVID spike in West Bengal: Experts
"We have been conducting genome sequencing on positive samples in West Bengal. A few subvariants of Omicron, mostly the BA.4 and BA.5 was found. But there is nothing to worry about. The BA.5 subvariant though highly infectious is not that threatening, at least for those who have no comorbidities," Siddhartha Niyogi, director of health services said.
