COVID-19 Infection During Pregnancy and Hearing Loss in Infants: A Clinical Study.

AIMS

To find the prevalence of hearing loss in children born to mothers who had COVID-19 infection during pregnancy.

MATERIALS AND METHODS

This was a prospective observational study conducted on 1960 babies born to mothers who were COVID positive during their pregnancy .All children born to RTPCR positive COVID-19 pregnant women were included in the study and babies who had any other risk factor for neonatal SNHL were excluded from the study. All the babies were subjected to OAE, and if it came pass, the test was repeated 2 weeks later. Those patients with repeat OAE also as refer were subjected to Brainstem Evoked Response Audiometry and findings correlated.

RESULTS

The study included 1960 neonates who were subjected to neonatal hearing screening by OAE. There were 1020 males (52.04%) and 940(47.96%) females and 80 cases of consanguinity. Fifty babies were excluded due to comorbidities. In the initial OAE test 380 neonates failed (19.9%) following which BERA was done and ten patients was found to Sensorineural hearing loss.

CONCLUSION

The prevalence of hearing loss in our study on babies born to mothers with COVID-19 infection during pregnancy is 0.005. Although these primary results from our study does not indicate any immediate effect of SARS-COV-2 maternal infection on neonatal hearing. More children need to be tested and followed up over an extended period of time to detect any possible delayed auditory effects. Those patients who were identified to have hearing loss in our study will have to be on long term follow-up as we see long terms effects on cognition, memory, heart health, etc. in COVID survivors.
