In the last three years, several arbovirus epidemiological emergencies have been reported in the Americas: the Chikungunya outbreak in Paraguay in 2023; the Western Equine Encephalitis outbreak in Argentina, Brazil, and Uruguay in 2023-24; the spread of Oropouche outside of usual areas, including the Caribbean, with transmission reported in Cuba and Panama; the Yellow Fever alert in 2024-2025; and the dengue emergency in 2024 with more than 13 million reported cases. As of epidemiological week 41 of 2025, more than 3.3 million cases of dengue have been reported, along with the circulation of all four viral serotypes, including the circulation of the new lineage of dengue 3 virus, which is gradually spreading to other countries.

In view of this complex epidemiological context, the PAHO/WHO Collaborating Center for the Study of Dengue and its Control, the Institute of Tropical Medicine, “Pedro Kouri”, the Cuban Society of Microbiology and Parasitology, and the Ministry of Public Health of the Republic of Cuba, the Pan American Health Organization/World Health Organization are pleased to announce that the 19th International Course on Dengue, Oropouche, and other emerging arboviruses will be held from August 17 to 28, 2026, to provide training and prepare for new arbovirus epidemiological emergencies.

The course will allow updating and discussing the global and regional epidemiological situation and the advances in the understanding, prevention, and control of these diseases, as well as the complexity of addressing and preventing them.
Topics of the course include the clinical management and differential diagnosis, laboratory diagnosis and surveillance in the context of co-circulation of several arboviruses, control of vectors involved in transmission, advances in research on pathogenesis, vaccines, individual, viral, and vector genetics, as well as new control tools, the influence of climate change on the emergence of diseases transmitted by Aedes mosquitoes, and the management of outbreaks in the face of the new scenario of arbovirus cocirculation.
New international initiatives and their impact on the emerging control of arboviruses will be shared.
