Abstract

COVID-19 belongs to a group of Coronavirus diseases that SARS-CoV-2 causes. The virus spreads from one person
to another via the respiratory droplets from an infected individual produced when such an individual coughs,
talks, or sneezes. The symptoms of the diseases range from mild to severe, and individuals at age extremities, that
are, very old (from 65 years of age), are highly exposed to severe complications. The symptoms manifest from the
second day, fourteen days after exposure to the virus. COVID strains keep on changing as a result of mutations in
the viral genomic composition. Different variants of COVID-19 exist; these variants vary in severity, as reported
by the World Health Organization. There are thousands of variants of COVID in the world; the virus mutates
all the time, making the changes inconsequential. Some of the mutations make the virus more infectious, and
some mutated viral strains tend to be dominant. Variants of concern include those that have the most potentially
concerning changes. India is among the nations where the virus strains have been reported to dominate and
spread to other nations. The virus is claiming the lives of many individuals, with every strain spreading from
one country to another. The article will address the research review on types of COVID variants and COVID-19
epidemiology in the world
