“…In most of these studies, however, the prenatal exposure to ZIKV occurred in the second trimester, specifically during week 20 of pregnancy. (14) In the cases included in this study with loss of hearing, the exposure to ZIKV did not occur during the second trimester of pregnancy. It is well known that infections can also lead to conduction hearing loss by producing lesions in the external ear canal, the eardrum membrane or the middle ear.…”

“…It is well known that infections can also lead to conduction hearing loss by producing lesions in the external ear canal, the eardrum membrane or the middle ear. (14) Furthermore, different authors sustain that, although there is no type of hearing loss detected at birth, it is essential to systematically evaluate all patients, (14) and it is possible that a sequel of a prenatal infection producing conduction hearing loss may be observed in a larger number of patients.…”

Introduction: The infection of the Zika virus that is endemic in Asia and Africa has now been extended to the Americas. This virus is considered teratogenic, producing a new disease that must be studied in depth. Objetives: This is to identify the clinical expressions found in children from mothers infected with the Zika virus during their pregnancy, and thereby establish the possible association of the time of the prenatal exposure to the Zika virus and the positive clinical findings. Methods: We carried out a transversal descriptive study, with 86 children from women having had an infection by the Zika virus, which were pregnant between January 2016 and December 2018. For the correlation between the presence of positive findings and the trimester of pregnancy at the detection of the infection by the Zika virus, we used Spearman’s correlation with a significance level of p ≤ 0.05. Results: Out of the total number of patients included in the study, 27 expressed a positive clinical finding. Among the neurological disorders, those related to muscular tone were the most frequent (15.48%), followed by psychomotor retardation (10.71%) and microcephaly (9.52%). An association was observed between the prenatal exposure to the Zika virus during the first trimester of pregnancy and the presence of positive clinical findings. Conclusions: There was a prevalence of neurological expressions, followed by visual expressions. The evidence proved that the exposure to the Zika virus during the first trimester of pregnancy had a teratogenic effect.

“…The exact site in the auditory system of the lesions caused by Zika virus is still uncertain [31] , and the data presented herein do not clarify this issue [31] . Audiological tests addressing central auditory process assessment could provide useful information; however, the severe neuromotor disabilities often experienced by children with CZS represent a major limitation for investigating behavioral manifestations [32] , [33] . Long latency ABR tests have also been used for this purpose, with the advantage of not being affected by neurological impairment, although definitive results are still unavailable.…”

How does the auditory function of children with congenital Zika syndrome present during the first three years of life? To determine the auditory function of children with congenital Zika syndrome during the first three years of life and estimate the frequency and long-term presentation of hearing loss in this syndrome, an auditory assessment with screening and diagnostic tests was conducted. The screening test consisted of measuring the short latency ABR using click stimuli. If the ABR click indicated hearing loss, confirmation was obtained with a frequency-specific ABR (FS-ABR), in which the stimuli were tone bursts at frequencies of 500 and 2000 Hz by bone and air conduction. This case series included 107 children with confirmed congenital Zika syndrome, and the cumulative incidence of sensorineural hearing loss in the first three years of life was 9.3% (10/107). There were no cases of delayed-onset or progressive deficits in hearing. Early presentation of sensorineural hearing loss seems to occur with a higher frequency in children with congenital Zika syndrome than in the general population. Sensorineural hearing loss resulting from congenital Zika virus infection does not appear to present with delayed onset or with progressive deficits.

“…The sensorineural screening suggested hearing loss in 17.3% and visual impairment in 14.1% of the infants [ 191 ]. Almeida et al conducted a cross-sectional study of eighty-eight one-year-old children with normal hearing who were diagnosed with congenital Zika syndrome, of whom 44.3% demonstrated a delay in hearing acuity [ 192 ]. Animal studies have shown that ZIKV can be detected in all areas of the inner ear, associated ganglia, and the surrounding periosteum interstitium following injection of ZIKV into the ear capsule/cup on days two to five of chick embryos, with a significant increase in nerve cell death.…”

Virus infection is one of the most common etiologies of hearing loss. Hearing loss associated with viral infection can be unilateral or bilateral, mild or severe, sudden or progressive, and permanent or recoverable. Many viruses cause hearing loss in adults and children; however, the pathogenesis of hearing loss caused by viral infection is not fully understood. This review describes cytomegalovirus, the most common virus causing hearing loss, and other reported hearing loss-related viruses. We hope to provide a detailed description of pathogenic characteristics and research progress on pathology, hearing phenotypes, possible associated mechanisms, treatment, and prevention measures. This review aims to provide diagnostic and treatment assistance to clinical workers.
