Background The 2022-2023 mpox(monkeypox)outbreak has spread rapidly across multiple countries in the non-endemic region,mainly among men who have sex with men(MSM).In this study,we aimed to evaluate mpox's importation risk,border screening effectiveness and the risk of local outbreak in Chinese *** We estimated the risk of mpox importation in Chinese mainland from April 14 to September 11,2022 using the number of reported mpox cases during this multi-country outbreak from *** and the international air-travel data from Official Aviation *** constructed a probabilistic model to simulate the effectiveness of a border screening scenario during the mpox outbreak and a hypothetical scenario with less stringent quarantine *** we further evaluated the mpox outbreak potential given that undetected mpox infections were introduced into men who have sex with men,considering different transmissibility,population immunity and population *** We found that the reduced international air-travel volume and stringent border entry policy decreased about 94% and 69% mpox importations *** the quarantine policy,15-19% of imported infections would remain *** a case of mpox is introduced into active MSM population with almost no population immunity,the risk of triggering local transmission is estimated at 42%,and would rise to>95% with over six *** Our study demonstrates that the reduced international air-travel volume and stringent border entry policy during the COvID-19 pandemic reduced mpox importations ***,the risk could be sub-stantially higher with the recovery of air-travel volume to pre-pandemic *** could emerge as a public health threat for Chinese mainland given its large MSM community.

Tripartite partnership, compared with the bilateral model, is envisioned as an opportunity to foster stronger and more trusting partnerships [1]. However, China has historically been characterized as principally reliant on bilateral engagement in global health [2]. The China-Tanzania Cooperation Project on Malaria Control was conducted by National Institute of Parasitic Diseases at China CDC and Chinese center for Tropical Diseases research, Ifakara health Institute in Tanzania and funding agencies from 2015 to 2022, with an aim to explore the applicability of Chinese experience on malaria control to reduce malaria disease burden in the local context of Tanzania. In the tripartite project funded by the former UK Department for international Development (DFID) and later the Bill & Melinda Gates Foundation (BMGF), China's partners were expected to share the extensively parallel practices achieved from the control and elimination of malaria for over 70 years, UK's partners were to deliver resources and design global health strategies, while Tanzanian local staff collaborated with triangular partners to ensure the project implementation [3]. In the project, the trilateral cooperation has transparent management mechanism to ensure the concrete management and implementation of the project [4] (Additional file 1: Figure S1). This Brief is to provide recommendations for China's engagement in global health by distilling the experience from the innovative tripartite partnership of the project.
