Microcefalia no Piauí, Brasil: estudo descritivo durante a epidemia do vírus Zika, 2015-2016

“…17,18 In addition, the introduction of Zika virus happened before the increase of microcephaly cases in Sinasc, as the literature indicates that the virus has been circulating in Brazil since October 2014. 12,13 Laboratorial confirmation of infection in the first trimester of pregnancy strengthened the hypothesis of a possible relation between Zika virus and microcephaly cases. 19 In 2015, the highest incidence of probable dengue cases in Piauí occurred in April 20 and the highest prevalence of microcephaly cases in December, a period of nine months between the two events.…”

“…9,10 A study using data from the Information System on Live Births (Sinasc) estimated an annual average of 164 cases of microcephaly from 2000 to 2014; in 2015, however, 1,608 cases were reported, with a prevalence of 54.6/100 thousand live births. 11 In October 2015, six months after the confirmation of autochthonous transmission of the Zika virus in the Northeast region of Brazil, 12 an unexpected increase in the occurrence of microcephaly was observed, especially in Pernambuco State, with the confirmation of 40 children born since August 2015. 13 Studies carried out during the same period have also detected an increase in microcephaly occurrence in Brazil, in comparison to previous years, mainly in the Northeast.…”

“…60 ZIKV continued to expand to other Pacific Ocean Islands 4,5,59,61-64 and through Southeast Asia, [65][66][67][68][69][70][71][72] until it was identified in the Americas in May 2015. [73][74][75] Between 2015 and 2016, seroprevalence in Brazil was 63% ( Table 1).…”

Aedes Aegypti E Arboviroses No Brasil

“…Um estudo realizado por Fantinato et al (2016) com foco no Rio Grande do Norte, Maranhão e Paraíba confirma a circulação do Zika vírus e descarta outros agentes etiológicos no surto ocorrido no ano estudado. Dos casos investigados no estudo, observou-se que os sintomas foram característicos de febre pelo Zika vírus, com exantema e ausência de febre ou febre baixa e um dos seguintes sinais/sintomas, hiperemia conjuntival, artralgia ou edema de membros.…”
