COVID-19 MEANING and which state has first virus infected people
Answers
Answer:
COVID-19 is a disease caused by a new strain of coronavirus. 'CO' stands for corona, 'VI' for virus, and 'D' for disease. Formerly, this disease was referred to as '2019 novel coronavirus' or '2019-nCoV.'The first human cases of COVID-19, the disease caused by the novel coronavirus causing COVID-19, subsequently
named SARS-CoV-2 were first reported by officials in Wuhan City, China, in December 2019. Retrospective
investigations by Chinese authorities have identified human cases with onset of symptoms in early December 2019.
While some of the earliest known cases had a link to a wholesale food market in Wuhan, some did not. Many of the
initial patients were either stall owners, market employees, or regular visitors to this market. Environmental samples
taken from this market in December 2019 tested positive for SARS-CoV-2, further suggesting that the market in
Wuhan City was the source of this outbreak or played a role in the initial amplification of the outbreak. The market
was closed on 1 January 2020.
