Risk assessment of global infectious disease events in September 2024

  • Objective To detect global infectious disease events occurring outside China in September 2024 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 September 2024, 18 infectious diseases were detected to form events or outbreaks in 47 countries worldwide. In terms of importation risk to China, there are 42 medium-risk events; in terms of international travel risk, there are 12 high-risk events and 54 medium-risk events.
    Conclusion It is recommended to pay moderate attention to dengue fever in the Americas and Asia, eastern equine encephalitis, mpox, West Nile virus disease, and Oropouche fever in North America, mpox, cholera, chikungunya fever, and poliomyelitis in Asia, cholera and Marburg hemorrhagic fever in Africa, and diphtheria and West Nile virus disease in Europe. In terms of the risk of overseas travel, it is recommended that travelers continuously focus on the dengue fever in Honduras, Brazil, Thailand, Vietnam, Sri Lanka, and Bangladesh. In September, travelers should pay extra attention to Oropouche fever in the United States, dengue fever in Panama, the Central African Republic, India, and Indonesia, and chikungunya fever in India. In addition, it is also necessary to pay moderate attention to the infection risks that may be brought by dengue fever, cholera, chikungunya fever, West Nile virus disease in Europe, mpox in the Americas, chikungunya fever and West Nile virus disease in North America, mpox, cholera, poliomyelitis, Marburg hemorrhagic fever, and plague in Africa, and dengue fever, mpox, cholera, chikungunya fever, poliomyelitis, West Nile virus disease, and Zika virus disease in Asia.
