On December 31, 2019, China reported a case of mysterious pneumonia of unknown cause. Within 3 days, the number of patients with these cases was 44 patients and continues to increase until now there are millions of cases. Initially, the epidemiological data showed that 66% of patients were related to or exposed to a seafood market or live market in Wuhan, Hubei Province, China. Samples of isolates from patients were studied with the results showing the presence of coronavirus infection, a new type of betacoronavirus, named 2019 novel Coronavirus (2019-nCoV). On February 11, 2020, the World Health Organization named the new virus SARS-CoV-2 and the disease name as Coronavirus Disease 2019 (COVID-19).
