COVID-19, caused by a coronavirus, has led to a pandemic that threatens everyone. Everyone in the world is worrying about COVID-19 (Corona Virus Disease-19). In late December 2019 an unidentified Corona virus, currently named as COVID-19 emerged from Wuhan, China. In this paper a brief description is given on Corona virus, its effects, safety measures and various modes of transmission of virus. A comparative study also done on the situation and safety measures of various countries to control the pandemic. In our study, it is observed that this virus is not a living organism and it has a genetic material inside an envelope. It is covered with the fat envelope known as lipid envelope. There are two different types of viruses namely Endemic and Pandemic. Endemic is something belongs to a particular people or country where as Pandemic is an epidemic that spread’s over different countries and continents. An Epidemic is a disease which affects a large number of populations within the region. Many researchers are working on these viruses. Corona virus is an Epidemic initially as it was born in Wuhan, China but its geographical Spread turned it as Pandemic declared by World Health Organization (WHO)[XIII]. 200 plus countries effected with this Virus. Long ago the similar kind of RNA sequences was circulated in Bats also known as SARS- COV (1) which created severe acute respiratory problems to the victim. After few years another virus MERS- COV was identified[XVIII, XV].
