Novel Coronavirus

Coronavirus disease 2019 (COVID-19) is well-defined as illness triggered by a novel coronavirus now called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2; formerly called 2019-nCoV), which was first identified amid an outburst of respiratory illness cases in Wuhan City, Hubei Province, China.  It was chiefly informed to the WHO on December 31, 2019. When humans first contract a coronavirus, it frequently effects from contact with an infected animal. Some of the furthermost common carriers are bats, however they do not typically transmit coronaviruses directly to humans. Instead, the virus might pass through an intermediary animal, which will usually, however not always, be a domestic one.
