[The historical data of pandemic influenza in China from 1918 to 1920 in the Shun Pao].

China was not been isolated from the Spanish flu which begun in 1918. According to the reports on the influenza epidemic in China from 1918 to 1920 in the Shun Pao(, Shanghai Daily), the plague was rampant in China three times, involving at least three cities including Beijing, Tianjin and Shanghai, and more than 14 provinces including Heilongjiang, Jilin, Jiangsu, Zhejiang, Anhui and Guangdong. Among them, the first wave of epidemic reports were mainly in June and July 1918, the disease was relatively mild. The second wave outbroke on October to November, with aggravating symptoms and a significant increase in the number of patients and deaths, Ningbo, Shaoxing, Jiaxing in Zhejiang Province were the worst, and Beijing, Anhui, Henan, Hunan, Shanghai and other places were also serious. The third wave occurred in the spring of 1919, Shanghai, with more reports. In previous works on the 1918 pandemic, there are few descriptions about the epidemic in China, therefore, the reports on the 1918-1920 pandemic in Shun Pao are important historical data supplement to the most deadly natural disaster in human history.
