With various wearing actions for the test, the subjective evaluation for mask-wearing air tightness was compared with the fit test pass rate in terms of consistence, the kappa value range being from −0.09 to 0.43. K value of the action 5 (loudly speaking) was above 0.4, while the k values of other 6 actions were all below 0.4.

It is currently spreading globally including Japan. The COVID-19 case in Japan began to appear in middle January 2020 and continued to increase over time. The period from middle January to the end of February is considered to be the initial stage of domestic transmission in Japan. This article described the spread of 935 COVID-19 cases related to Japan by the end of February 2020, including the 15 infected Japanese returned from Wuhan, the 696 infected individuals in the large-scale cruise ship \"Diamond Princess\" and the 224 infected individuals in Japan. This paper summarizes the measures to control the spread of SARS-CoV-2 in Japan, such as limiting RT-PCR detection for SARS-CoV-2, reducing the number of patients with mild illness who go to medical institutions unnecessarily, formulating guidelines for SARS-CoV-2 infection consultation, canceling large gatherings and temporarily closing schools. This paper further points out the problems encountered in the prevention and control of the spread of SARS-CoV-2 in Japan, such as the slow detection of RT-PCR, the risk of infection faced by medical staff, the regional differences in the domestic health care service system, the confusion of information disclosure and management.

The peak date for new cases was on February 1, with the number of cases reaching 26. The confirmed cases were mainly concentrated in Asian countries, but also distributed in Europe, North America, Oceania and Africa. As of February 15, there was no more increase reported in the number of countries where confirmed cases occurred after reaching 25. Among these countries, Singapore, Japan, and Thailand were with the highest number of cases, with 77, 65, and 35 cases, respectively.
