[Correspondence] Dengue vaccine and the 2016 Olympics

Between Aug 5 and Aug 21, 2016, more than 380 000 tourists and 10 500 athletes are expected to visit Brazil for the 2016 Olympic Games held in and around Rio de Janeiro. Last year in Brazil, there were 1 642 024 probable cases of dengue with 839 deaths. Typically, 12% of these cases occur in the state of Rio de Janeiro and about half that number in the city (Siqueira JB, Institute of Tropical Pathology and Public Health, Goiânia, Brazil, personal communication). Additionally, both chikungunya and Zika viruses are transmitted in Brazil during the hot, rainy season of December to March.
