Dear Colleagues,
It is our great honor and pleasure to welcome you to the Shanghai International Syphilis Symposium (SISS 2025), taking place in Shanghai from October 20 to 22, 2025. This invitation-only symposium convenes an extraordinary group of global experts in research, clinical care, and public health to confront the urgent and evolving challenge of syphilis in the twenty-first century..
We are especially proud to host this meeting in Shanghai, a city renowned for its rich history, cultural vibrancy, architectural beauty, hospitality, and strong commitment to global health. We hope this gathering will not only advance scientific exchange but also foster meaningful partnerships and inspire collective action that extends well beyond the event itself.
As Co-Chairs, we believe that multidisciplinary collaboration and bold innovation are key to transforming the landscape of syphilis control and prevention. We are confident that the discussions and insights shared here will inform new strategies, catalyze impactful initiatives, and strengthen the global response to syphilis.
We thank you for your dedication and participation, and we warmly welcome you to what promises to be a stimulating, productive, and historic symposium.
Sincerely,
Pingyu Zhou Co-Chair
