How did the first case of COVID-19 in Guangzhou come about?

Outsiders return to Guangzhou. According to Guangzhou’s epidemic prevention and control data, the first case of COVID-19 in Guangzhou was infected by a foreigner who returned to Guangzhou. Case 1, female, 21 years old. On the morning of February 14, 2020, I arrived in Nansha from another city. I drove to Guangzhou Hospital of Integrated Traditional Chinese and Western Medicine for nucleic acid sampling at 9:00 pm on the 14th. I then checked into the Hampton Inn by Hilton in Huadu District and took the nucleic acid test at 8:30 on the 15th. The initial screening report was positive, and the results of re-sampling and review by the municipal and district CDCs were all positive.
