Introdução: No início de 2015 foram detectadas as primeiras infecções do vírus Zika no Nordeste do Brasil e no final do mesmo ano constatou-se a sua propagação para pelo menos quatorze estados brasileiros, incluindo Minas Gerais. Objetivo: Descrever o perfil epidemiológico dos casos de infecção por vírus Zika em Juiz de Fora, com foco especial nas gestantes infectadas. Materiais e Métodos: Dados referem-se ao período de janeiro de 2016 a junho de 2019, da cidade de Juiz de Fora obtidos através do Departamento de Vigilância Epidemiológica e Ambiental, do Sistema de Informação de Agravos de Notificação e do Registro de Eventos em Saúde Pública (RESP). Foram extraídos: data das notificações, idade, sexo, período de gravidez, raça, nível de escolaridade, se a infecção foi autóctone, bairro de residência e critério utilizado para confirmação da infecção. Resultados: 288 casos tiveram a confirmação através de exames laboratoriais (RT-PCR), sendo 19 gestantes. Não houve registro de óbitos ou abortos pela infecção. Em 13 dos 19 casos em gestantes, o RESP não foi completamente preenchido. A média de idade foi 36,69 ±17,81 anos, 68,05% do sexo feminino, e o nível de escolaridade predominante foi fundamental incompleto e médio completo. Conclusão: Apesar dos dados incompletos nos sistemas de notificações, foi identificada maior taxa de infeção no sexo feminino, na faixa etária de 20 a 49 anos.

The known neurotropism of the Zika virus (ZikV) suggests that auditory organs and their neural pathways may be affected by prenatal Zika infections. Among the possible manifestations are audiological and language disorders, but so far, the data in the literature are inconclusive. Objective: To describe early and late hearing disorders in children with Congenital Zika Virus Infection (CZVI) and evaluate the language development of this population between 14 and 47 months of age and its possible correlation with the alterations found in auditory exams. Methods: Longitudinal, prospective, observational study of newborns born in Juiz de Fora and its macroregion with confirmed diagnosis of ZikV infection during pregnancy. Participants were examined from one to four years of age for hearing using the transient otoacoustic emissions (TOAE) test, immittance testing and brainstem auditory evoked potential (BAEP), and language using the Bayley Scales of Infant Development—Third Edition (Bayley III). Results: 15 participants were included; eight (53.33%) presented alterations in at least one of the hearing tests, one had an early loss (6%) of sensorineural origin, and seven (46.67%) had a poor language performance. In the three (20%) participants whose audiological exams were altered, there was language impairment, and two (13.33%) participants had extensive malformations in the central nervous system (CNS), presented language delay, and hearing exams were within normality. Conclusion: Infants and preschoolers with CZVI may present early neurosensory loss and late hearing loss with fluctuating character. Even if there were no significant association between the audiological exams results and the Bayley III performance, in the present sample, language development was below expectations for the age in the participants who had alterations in the three audiological exams, when there is early hearing loss or extensive lesions to the CNS. The results reinforce the importance of audiological examinations, especially the BAEP morphological and auditory threshold, in monitoring cases of CZVI until at least three years of age.
