10th INTERNATIONAL CONFERENCE ON TYPH ID & OTHER INVASIVE SALMONELLOSES April 4–6, 2017 | Kampala, Uganda 10th INTERNATIONAL CONFERENCE ON TYPH ID & OTHER INVASIVE SALMONELLOSES WELCOME April 4–6, 2017 | Kampala, Uganda THE WORLD NEEDS ACTION ON TYPHOID — BUILDING EVIDENCE AND REFINING STRATEGIES The Coalition against Typhoid, housed at the Sabin Vaccine Institute, welcomes you to the 10th International Conference on Typhoid and Other Invasive Salmonelloses. We are pleased to provide a forum for more than 300 researchers, policy makers, immunization managers and advocates to come together to share the latest developments and best strategies to reduce the burden of typhoid, paratyphoid and nontyphoidal salmonelloses (NTS) on communities around the world. The conference theme, “From Evidence to Action,” is timely as we prepare for the introduction of new typhoid conjugate vaccines. The research, evidence and ideas shared this week in Kampala will provide the foundation for global action against typhoid, paratyphoid and NTS. Together, we will review crucial developments to reduce the global burden of these diseases, including results from major surveillance projects in Africa and Asia, the potential of human infection models and strategies for countering antibiotic resistance. The program will also highlight outbreak control methods, exciting innovations in diagnostics, water, sanitation and hygiene strategies for prevention, and policy measures aimed at accelerating the implementation of these interventions. The coming availability of a new generation of typhoid conjugate vaccines makes this a pivotal moment for global action on typhoid. These promising new vaccines offer important advantages over prior vaccines, including longer duration of protection, the ability to protect young children, and the potential for administration with other vaccines in routine immunization of infants. As Salmonella bacteria become increasingly resistant to available antibiotic treatments, conjugate vaccines have the potential to dramatically reduce the burden of typhoid around the world and consequently help to prevent the occurrence of antibiotic resistance. Working together to share research and generate evidence to shape solutions is more important than ever. We thank you for joining us and extend our gratitude to the Bill & Melinda Gates Foundation for their generous support of this conference, the world’s only conference devoted to typhoid and other invasive salmonelloses. In addition, we would like to thank the Ministry of Health of the Republic of Uganda for their assistance and hospitality. We look forward to three days of discussion, debate and forging new partnerships in the fight against typhoid.
