are indicators of dengue and chikungunya, point to ZIKV as the probable cause of several of the reported cases.Furthermore, laboratory-confirmed cases of infection with ZIKV were simultaneously identified in other cities within metropolitan Salvador (6,7) and in other states in Brazil (8).Low diagnosis of ZIKV infection is likely because viremia levels among infected patients appear to be low (9).The spread of ZIKV represents an additional challenge for public health systems, particularly because of the risk for concurrent transmission of DENV and CHIKV by the same vectors, Ae. aegypti and Ae.albopictus mosquitoes, which are abundant throughout tropical and subtropical regions.To date, the largest outbreak of chikungunya in Brazil occurred in 2014 in Feira de Santana, Bahia, ≈100 km from Salvador, where dengue is also prevalent (10).This report illustrates the potential for explosive simultaneous outbreaks of ZIKV, CHIKV, and DENV in the Western Hemisphere and the increasing public health effects of Aedes spp.mosquitoes as vectors.The apparent increase in reports of Guillain-Barré syndrome during the outbreak deserves further investigation to elucidate whether this syndrome is associated with ZIKV infection.Public health authorities in Brazil and neighboring countries should plan accordingly.
