Electronic Survey about Current Update of CORONA Virus Variants

Abstract

WHO, in association with partners, expert networks, national authorities, institutions and researchers have been monitoring and assessing the evolution of SARS-CoV-2 since in the month of January 2020.At the current time, this expert group summoned by WHO has indorsed using letters of the Greek Alphabet like Alpha, Beta, Gamma, Delta which will be easier and more applied to be conferred by non-scientific spectators.The efficiency of the current COVID vaccines is fairly high. In fact, it is much advanced than some other vaccines we generally receive. As an aide-memoire, the annual flu vaccine has an efficacy around 40-60 percent from year to year.
Numerous theories are on the surface to explain how the Omicron has congregated such a high number of mutations within less time. Few of them are advanced mutation rates within a subgroup of population and then its introduction to a larger population, long term perseverance and evolution of the virus in immune compromised patients, and epizootic infection in animals from humans, where under dissimilar immune pressures the virus metamorphosed and then got reintroduced to humans .Transmission of SARS-CoV-2 is
thought to occur primarily through revelation to respiratory droplets. Breathe out droplets or particles can also deposit the virus onto exposed mucous membranes. Though a numerous number of variants will cause the COVID infection still proper precautionary measures can prevent the transmission of this infection.
