Abstract
The Zika virus epidemic is characterized as a total social fact 1, precisely because it synthesizes several determinations about epidemic processes by combining factors of economic and social inequality and revealing processes of vulnerability. This situation triggers a chronology of events that establish and dismiss the emergency: in November 2015, the Brazilian Ministry of Health issued a National Public Health Emergency 2; in February 2016, the World Health Organization (WHO) classified the Zika virus epidemic as a public health emergency of international concern 3; in March 2016, the Protocol for Surveillance and Response to the Occurrence of Microcephaly Related to Zika Virus Infection4 was published; in November 2016, the WHO no longer considered the Zika virus as an international emergency 5; and, in May 2017, the Brazilian Ministry of Health declared the end of the emergency 6.
