On December 31st, 2019, in Wuhan City, Hubei Province of China, 27 individuals developed pneumonia and all individuals had visited the seafood market in the area. The local centers for disease control and prevention, upon concluding that the novel infection had originated from overseas, established a “countermeasures taskforce against pneumonia of unknown cause” and set the crisis level to Blue. Accordingly, the situation overseas was constantly monitored, and surveillance in China was initiated, and responses initiated to suspected cases of infection. For suspected cases, a basic epidemiological assessment was conducted at the local health center and at the discretion of the central investigator, the patient was either admitted to a state-designated, negative-pressure isolation ward for further testing, or control measures of self-isolation and active surveillance were undertaken [3].
