Background: The coronavirus disease-2019 (COVID-19) pandemic has affected more than 200 countries countries across the world, and most outbreaks have been a result of imported cases. On January 23, 2020, the Chinese government decided to impose a quarantine on Wuhan with the aim of controlling the spread of the epidemic. We analyzed data about the COVID-19 infections imported from outside into six Chinese provinces and studied the effectiveness of epidemic prevention and control in China.
Methods: We analyzed data released by the Health Commission of Guangdong, Hunan, Jiangxi, Henan, Zhejiang, and Anhui provinces from January 23 to March 16, 2020. We examined the following: the cumulative number of confirmed cases, daily new confirmed cases, total number of severe cases in the hospital, cumulative number of deaths, and cumulative number of recovered cases.
Results: From January 23, 2020, to March 16, 2020, there was a 45·1-fold increase in the total confirmed cases. The highest increase occurred on February 3 in 6 provinces, i.e., 12 days from January 23. From February 4–15, the daily number of new confirmed cases gradually decreased by 90% in six provinces. From February 16–27, no new confirmed cases appeared in the 6 provinces. As of March 16, the average rate of severe cases was 10·7% in five provinces, 2·2% in Anhui province, and the total case fatality rate and recovery rate were 0·6% and 98·9%, respectively.
Conclusions: The lockdown of City appears to have been effective in controlling the spread of the epidemic. The inflection point appeared on February 3, and after prevention and control for over a month, there were no more confirmed cases in the hospital in 5 provinces. This successful experience is worth learning from other countries and can effectively combat the outbreak of imported COVID-19.
