Zika Virus: A New Chapter in the History of Medicine.

A change in the clinical-epidemiological pattern Zika virus is an arbovirus of the Flaviviridae Family. Its identification occurred in 1947 in Uganda; however, the occurrences of human infection were reported in an isolated and sporadic form with a large part of asymptomatic individuals. The epidemic potential was perceived since 2007 in Micronesia; however, in 2013, mainly in the French Polynesia, a change in the pattern was observed, with high rates of attack, estimating the occurrence in 11% of the population.1 In Brazil, since November 2014 and mainly in the beginning of 2015, the Northeast states reported a great outbreak of a new exanthematic disease. The clinical condition, characterized by an early onset exanthema, with no or little fever, accompanied by arthralgia, articular edema and conjunctivitis, led the infectologist Kleber Luz to consider the hypothesis of Zika virus. This was confirmed in April 2015 through PCR performed on eight of the 25 blood samples from suspected cases in Bahia, and subsequently in eight of the 21 cases in Rio Grande do Norte.2,3 The outbreak presented a high rate of attack, with thousands people affected overcrowding the public and private emergency services, although it was not measured by an official notification system. Since this was not a disease of mandatory notification, even in cases suspected of Zika, doctors of the services were oriented by the health inspection surveillance to notify as Dengue. After the outbreak of the disease in its classical form, neurological and microcephaly cases began to arise.
