In 2019，the overall situation of tourism-related public health security in China was still severe，with an overall trend of aggravation. The numberof food poisoning incidents increased，but the total number of cases decreased，and the event level decreased. The incidence of travel-related infectious diseases increased at a high rate. In the winter，norovirus outbreaked and tourists infected with infectious diseases increased in southeast Asia. At at the end of the year，COVID-19 epidemic occurred in wuhan. The number of travel-related emergencies and cases in 2019 were basically the same as in 2018，but death toll rised. Travel-related public health incidents tended to occur in July，when summer heat and student holidays overlap In 2019，the state strengthened food safety legislation and supervision and assessment of food safety management personnel，and required food manufacturers to strengthen safety knowledge training，while strengthening the direct report of infectious diseases and public health emergencies.The key factors in the grim public health security situation in 2019 were the outbreak of viral infectious diseases，the weak awareness of tourists，and loopholes in supervision and control. Therefore，travel related departments at all levels throughout the country should strengthen safety awareness education and law enforcement supervision and management in 2020；and promote international collaboration on public health in tourism. And we will further improve the tourism public health risk prevention and emergency rescue service network.
