OBJECTIVE: Gestational SARS-Cov-2 infection may impact maternal and newborn health. The virus has also been reported to cause sensorineural hearing loss. The objective of this study was to determine the possible effect of maternal SARS-COV-2 infection on neonatal hearing, as identified during universal hearing screening.
Methods: Retrospective cohort study in two tertiary reference centers including all newborns born from November 2020 to April 1, 2021 and benefiting from the universal hearing screening program. Maternal Covid-19 infection was recorded (timing and severity) and the hearing screening results of their newborns compared to the incidence of neonatal deafness results from the National Universal Screening Program during the same period.
RESULTS: A total of 984 newborns were included (508 males and 476 females). Sixty-three newborns were excluded due to comorbidities that could lead to hearing loss. The incidence of response failures in the general community was 2.3%. Twenty-seven failed both stages of screening (2.9%; p
CONCLUSION: In this study, newborns born to mothers positive for Covid-19 did not appear to have an increased risk of hearing loss. However, a longer follow-up of these newborns is mandatory to detect any delayed effects of the virus.
