The 9^th International Dengue Workshop Singapore was held from November 4-13, 2025 under Singapore's international cooperation framework. Co-organized by the Ministry of Foreign Affairs, Singapore's National Environment Agency, and the World Health Organization, the program aimed to provide a comprehensive overview of modern dengue surveillance and control methods while strengthening the links between laboratory diagnostics, clinical management, and vector control. It brought together 24 specialists from 19 countries, creating a valuable platform for exchanging expertise and fostering multilateral collaboration. Representing the Pasteur Institute of Iran, Dr. Tahmineh Jalali, Head of the Arboviruses and Viral Hemorrhagic Fevers Department of the institute, participated in the workshop's laboratory working group. Inaugurating the event, a Senior Minister of State for Singapore delivered the opening address. Echoing the workshop's theme, "United Against Dengue: From Global Cooperation to Local Action", he highlighted the alarming global increase in dengue cases in recent years. He identified climate change, urbanization, and global mobility as key drivers of this trend and underscored the vital role of international scientific networks in combating the disease. Such networks, he noted, enhance cooperation among nations through strengthened genomic surveillance and data exchange.

Throughout the workshop, participants received intensive training across multiple domains. Sessions covered practical next-generation sequencing using nanopore technology, advanced serological testing, disease transmission modeling, and spatial risk mapping. Reviews of other countries' field surveillance experiences further contributed to a multidimensional, integrated perspective on dengue control. A visit to a facility producing Wolbachia-carrying mosquitoes demonstrated how effectively linking laboratory research, clinical practice, and field operations can create a highly efficient control system—an approach Singapore has successfully implemented over decades.

A significant outcome for the country from this workshop was the privilege granted to the Pasteur Institute of Iran to nominate a representative for future sessions. This valuable achievement, earned through the active participation and scientific contributions of the Iranian delegate, ensures the country's continued presence in the region's scientific and operational network and solidifies Iran's role in international dengue-related initiatives. To fully leverage this opportunity, planning for the transfer of knowledge acquired from other countries is essential. This can be achieved through follow-up training workshops, cascade training programs, and updates to national laboratory protocols. Such steps will ensure the sustainable application of the workshop's insights and pave the way for developing a more integrated and efficient national surveillance system.
