In May 2015, the Ministry of Health of Brazil confirmed autochthonous transmission of ZIKV in the north-eastern part of the country. This was the first documented outbreak in Brazil and in the Americas. As of October 2015, 14 states have confirmed autochthonous virus transmission: Alagoas, Bahia, Ceará, Maranhão, Mato Grosso, Pará, Paraíba, Paraná, Pernambuco, Piauí, Rio de Janeiro, Rio Grande do Norte, Roraima, and São Paulo.In October 2015, the Ministry of Health of Colombia reported the first autochthonous case of ZIKV infection in the Department of Bolivar. As of 16 October 2015, ZIKV was laboratory confirmed in 9 of 98 samples from Bolivar. Recent outbreaks of ZIKV infection in different regions of the world underscore the potential for the virus to spread further in the Americas and beyond, wherever the vector is present. Given the worldwide spread of chikungunya and dengue, associated with urbanization and globalization, there is a potential risk of outbreaks of urban ZIKV infection in urban settings in any part of the world where the mosquito vector is present or may become established in future.
