In which city was the first human case of SARS-CoV-2 infection identified in December 2019?

• A. Beijing
• B. Wuhan
• C. Shanghai
• D. Guangzhou

Answer: (B)

The initial identification of SARS-CoV-2 infections traces to Wuhan, a major city in central China. In December 2019, health authorities reported a cluster of pneumonia cases of unknown cause in Wuhan, and early investigations connected many of these cases to the Huanan seafood market there. This is why Wuhan is considered the place where the first human infections were identified. Beijing, Shanghai, and Guangzhou did not have the earliest reported cases in December 2019; they appeared later as the virus spread.
