Abstract:
Objective To detect global infectious disease events occurring outside China in February 2025 and assess the importation risk to China and international travel risk.
Methods Utilizing open-source intelligence on the internet, this study conducts event-based surveillance of priority infectious diseases and adopts the risk matrix methodology to build an indicator system by integrating disease-, country- and event-specific indicators in terms of transmission likelihood and severity of consequences in order to assess the risk of the importation and the risk of international travel.
Results In February 2025, 10 infectious diseases were detected to form events or outbreaks in 23 countries worldwide. In terms of importation risk to China, there are 3 high-risk events and 7 medium-risk events; in terms of international travel risk, there are 8 high-risk events and 15 medium-risk events.
Conclusion It is recommended to focus on the possible importation risk posed by Dengue fever from Indonesia, the Philippines, and Vietnam in Asia. International travelers are advised to focus on the risk of infection from dengue fever in Sudan, Brazil, Indonesia, the Philippines, Sri Lanka, and cholera in Sudan, South Sudan, Angola in Africa. Compared with January, in February, further attention should be paid to measles in North America and Europe, dengue fever in Asia, and cholera in Africa.
