New varient of covid-19 "Omicron" :đŋ
Recently The World Health Organization on November 26 declared the recently-discovered B.1.1.529 strain of COVID-19, first detected in southern Africa, to be a variant of concern and renamed it Omicron.
The classification puts Omicron into the most-troubling category of COVID-19 variants, along with the globally dominant Delta, plus its weaker rivals Alpha, Beta and Gamma.

"Omicron" Name came from
Greek alfabet
All viruses mutate over time, including SARS-CoV-2, the virus which
causes COVID-19 disease.
During late 2020, the emergence of variants that posed an increased
risk to global public health prompted the WHO to start characterising them as variants of interest, and the more-worrying variants of concern, to inform the response to the pandemic.
The U.N. health agency decided to name the variants after the letters of the Greek alphabet, to avoid the countries that first
detected them being stigmatised.
Why"omicron" declared as voc ?
The change in classification came after a quickly-assembled virtual meeting of the WHO's Technical Advisory Group on SARS-CoV-2 Virus Evolution.
The variant was first reported to the WHO from South Africa on
November 24.
The first known confirmed Omicron infection was from a specimen collected on November 9.
In recent weeks, infections in South Africa have increased steeply,
coinciding with the detection.
The 'concern' in VOC comprises three sinister properties - transmission efficiency, disease severity and escape from immunity cover of vaccination.
"This variant has a large number of mutations, some of which are concerning," the WHO said, pointing to worrying characteristics.
"Preliminary evidence suggests an increased risk of reinfection with
this variant, as compared to other VOCs."

Effect of omicron on travell
Despite countries scrambling to ban flights, the WHO earlier cautioned against imposing travel restrictions due to Omicron.
The organisation said countries should take a risk-based and scientific approach when considering travel curbs in light of the variant but cautioned against restrictions.
"At this point, again, implementing travel measures is being cautioned
against," spokesman Christian Lindmeier told reporters.
Effect of omicron on stock market
The benchmark indices at BSE and NSE fell sharply by nearly 3 per cent on Friday as concerns mounted over the new Covid variant.
STUDY
There was anxiety around US central bank likely to wrap up its stimulus programme and raise interest rates earlier than expected in the wake of rise in inflation.
These factors led to a sharp outflow of funds from Indian stock markets resulting in the decline in indices. Over the last three trading sessions FPIs have pulled out a net
of Rs 14,700 crore from Indian equities and thereby
resulting in the sharp decline in indices.
While the broad domestic economic fundamentals remain intact and markets may rise in the medium to long term, they are expected to remain under pressure over the coming weeks.
Experts say that it should not bother investors too much.
The long term investors should not sell their holdings in panic but only do so if their investment targets have been met and they are in need of funds.
Conclution about "omicron"
Besides Delta, Omicron and the three other VOCs, there are currently two lower variants of interest and below that, a further seven under monitoring.
Delta, which is more transmissible than the original strain, is now overwhelmingly dominant around the world, having all but out-competed other variants.
Of 845,000 sequences uploaded to the GISAID global science initiative
with specimens collected in the last 60 days, 99.8 percent were Delta.
