Omicron Sub-Variant BA.2.75 Detected In South Africa As Well
Omicron sub-variant BA.2.75 has also been detected in several other countries including India, where it was first detected in June.
Omicron sub-variant BA.2.75 has also been detected in several other countries including India, where it was first detected in June.
The study found that the neutralising activity against Omicron sub-variants such as BA.1, BA.2, BA.2.11, BA.2.12.1, BA.2.13, and BA.4/BA.5 "was not or only minimally detectable".
Omicron is the dominant variant of COVID in the world right now. But how long does it last? Does it last longer than its predecessor - the Delta variant?
The Centre has advised all States and UTs not to lower the guard and maintain a strict vigilance in areas that are showing concerns.
This new variant- Omicron BA.2.12.1, is also the reason behind the sudden spike in cases in the US.
Omicron BA.2 variant constituted 68.4 per cent of all whole genome sequenced samples in the state.
BA.2 is found to have quickly overtaken the original Omicron in South Africa and other countries and has even caused a second Omicron surge in Denmark.
Omicron contains over 35 worrisome mutations. Out of these 35 mutations in the variant's spike protein [used by SARS-CoV-2 to bind to a specific receptor when infecting human cells], only one was unknown.
The WHO chief said, "Depending on where you live, it might feel like the COVID pandemic is almost over or it might feel like it's at its worst, WHO chief said on Wednesday and further added, But wherever you live, COVID isn't finished with us."
The Omicron subvariant BA.2, dubbed "Stealth Omicron", is rising around the world with at least 55 countries, including India.
Both Moderna and Pfizer-BioNTech vaccines are based on messenger RNA technology, which allows them to easily update the vaccines to keep up with mutations specific to new variants.
Fewer hospitalisations in the third Covid-19 wave but 407 districts in 34 States and Union Territories are still reporting positivity rate of over 10 per cent, said Union home secretary Ajay Bhalla.
A new study has ruled out the theory of recombination of previous variants in the origin of Omicron, stating that the highly transmissible variant is likely the result of an evolutionary process.
However, an omicron infection in unvaccinated people does not produce antibodies that can effectively neutralise other coronavirus variants, says the UCSF study.
The highly mutated Omicron variant of COVID-19 was first detected in South Africa on November 24, 2021. The variant has already spread to over 100 countries and is currently leading the third wave in India.
Bharat Biotech has announced that Covaxin booster shots will be effective against both the Omicron and Delta variants of COVID-19. Read on to know more.
But protection against mild symptomatic Omicron infection drops to around 30 per cent by about 3 months after they received the booster shot, says the UK Health Security Agency.
With the rising number of daily cases, the Omicron threat is high right now, but the good news is none of the cases detected in India required emergency hospitalisation, ventilation, or any other serious kind of health treatment.
