According to the international authoritative medical journal "The Lancet" (also known as "The Lancet"), the first patient of Wuhan pneumonia appeared on December 1 last year . He has always kept a low profile on the development of the epidemic. On December 30, Li Wenliang, an ophthalmologist at Wuhan Municipal Hospital, found that the relevant medical record test reports were highly similar to SARS, and reminded medical students in the WeChat group that " 7 cases of SARS were diagnosed in the South China Fruit and Seafood Market ." At the same time , An official document of " pneumonia of unknown cause " was also circulated on the Internet .
When Chinese officials learned banner design of the outbreak, not only did they fail to fulfill their obligation to inform and explain, but instead used the power of the police to hide the outbreak. Li Wenliang was quickly warned and reprimanded by the police in his jurisdiction for "publishing false remarks on the Internet . " As late as the seventh week of the spread of the epidemic, Chinese officials began to take active measures to prevent the epidemic.
On January 23, Wuhan was closed and foreign air and land transportation were cancelled. However, before this, Wuhan residents were not informed of precautions for epidemic prevention, and New Year celebrations and gatherings were held as usual, increasing the risk of infection. An estimated 5 million people have left Wuhan for China and around the world before the city's lockdown. Since then, the total number of global cases has gradually surpassed 10,000 within two months.
