On February 14, 2020, the Central Epidemic Command Center (CECC) announced that more than 1,000 cases of coronavirus disease 2019 (COVID-19) have occurred in Henan and Zhejiang, China, respectively, and community-based transmission in the affected areas is hard to control. Most of the cases in Zhejiang are locally transmitted coronavirus cases and family clusters and suspected asymptomatic spread have been reported in Henan, the CECC added. Due to the developments of COVID-19 in the two Chinese provinces, the CECC announced that starting February 15, 2020, the abovementioned provinces will be listed as Level 1 Area based on endemic situations; in addition to the two Chinese provinces, Hubei province and Guangdong province had been listed as Level 1 Area, and the other Chinese provinces have been listed as Level 2 Area. Additionally, cases of unknown origins of infection continue to be reported in Japan recently, which might indicate invisible community-based transmission. Therefore, the travel notice level for Japan has been raised to Level 1: Watch, and the public is advised to practice usual precautions.
