OBJECTIVE: To evaluate auditory manifestations in children born to mothers who had exanthema during pregnancy, suspected to have been exposed to the Zika virus (ZIKV). STUDY DESIGN: Prospective observational. SETTING: Tertiary referral center. PATIENTS: Children born in Rio de Janeiro, Brazil, between April 2016 and September 2017, who were referred for newborn hearing screening (NHS). INTERVENTION: The NHS was performed by the automated brainstem auditory-evoked potential test at an intensity of 30 dBHL (decibels Hearing Level) with the result presented as "PASS/FAIL." A follow-up test was performed 6 months after the first examination. MAIN OUTCOME MEASURES: Hearing outcomes by audiological assessment. RESULTS: Ninety-eight children were recruited and 78 underwent the NHS test. In the first evaluation, the FAIL NHS result was observed in 4 of the 78 children. Three were diagnosed with sensorineural hearing loss and one had conductive loss. Including the first and second evaluation, the frequency of audiological alterations was 5.1%. Of the four children diagnosed with hearing loss, two were carriers of ZIKV, one had suspected ZIKV infection, and one was asymptomatic with confirmed exposure to the virus. There was no progression of hearing loss or other hearing abnormality in the children by the time of the second evaluation. The group of nonexposed children (negative quantitative reverse transcription polymerase chain reaction for ZIKV) showed no hearing loss. CONCLUSION: Uni or bilateral sensorineural hearing loss was diagnosed in asymptomatic children at birth. These observations highlight the importance of periodic follow-up of patients with congenital Zika syndrome to better understand their long-term auditory clinical outcome.
