The worst epidemic in Chinese mainland is in the first half of 2020. From February 2065438 to February 2009, the epidemic situation was first discovered in Wuhan, and it quickly spread from Wuhan to all parts of the country in just over a month without closing the city. By February, 2020, almost all provinces and municipalities directly under the Central Government in Chinese mainland have experienced this situation. The most serious is Hubei province, where thousands of cases occur every day and hundreds of cases die. In other places, some provinces and municipalities directly under the central government also have more than 100 cases every day, and some have dozens of deaths. By April, the epidemic situation had been well controlled because the state and local governments had taken protective measures such as closing cities. Including Wuhan, Hubei Province, are basically under control.
