“…Similar to our ndings, most studies published during the covid-19 pandemic do not support strong evidence of auditory system insult due to intrauterine infection by the SARS-CoV-2 virus mirrored on normal newborn hearing screening tests [14,[37][38][39][40][41]. However, other studies are showing a possible negative impact on hearing of newborns of mothers infected by covid-19 during pregnancy [15,16].…”

Purpose SARS-CoV-2, the responsible virus for the covid-19 pandemic, has demonstrated neurotropic properties indicated by cases presenting with auditory and vestibular system insults. The expression of ACE-2 receptors in the placenta and the detection of IgM antibodies against the virus in the fetuses of pregnant women suffering from covid-19 render vertical transmission of the infection to the fetus possible. Thus, our study aims to examine whether, similar to other viruses like CMV, SARS-CoV-2 is responsible for congenital hearing loss. Methods This is a retrospective study in a regional pediatric hospital. The medical records of newborns (n = 111) born by mothers positive for COVID-19 during pregnancy who underwent screening hearing tests with Transient Evoked Otoacoustic Emissions (TEOAE) and Automatic Auditory Brainstem Response (AABR) from February 2020 to June 2022 were reviewed. Neonates with additional aggravating factors for congenital hearing loss were excluded from the study. Results For the study period, nine mothers were found positive during the first trimester, twenty mothers in the second trimester, and eighty-three mothers in the third trimester. TEOAEs test and AABR test scored PASS bilaterally in all neonates tested. Conclusions Infection with COVID-19 during pregnancy was not a risk factor for hearing loss, similar to other studies.

“…They observed no statistically significant difference between cases and controls. Kosmidou et al [ 21 ] reported that 21.87% of neonates failed the first screening while all these neonates cleared the second screening. A study by Tanyeri Toker et al reported no significant association between COVID-19 infection during different trimesters and congenital hearing loss.…”

COVID-19 infection during pregnancy is potentially dangerous to neonatal hearing, as it is the period of organogenesis, and associated hyperthermia may cause vascular damage, disruption of cell migration, and death of the dividing neuroblasts. To investigate the possible association between neonatal hearing loss and gestational mild COVID-19 infection. A prospective case-control study was conducted at a tertiary healthcare centre in North India from March 2020 to Oct 2022. Cases included the neonates born to COVID-19-positive mothers were subjected to hearing screening at 1, 3 and 6 months using otoacoustic emission (OAE) and automated auditory brainstem response (AABR). Similar protocol was applied to controls, i.e., neonates borne to mothers with no gestational history of COVID infection. Results were analyzed statistically. Our study reported that the statistical difference between groups A (n = 942) and B (n = 942) for gestational COVID-19 infection and neonatal hearing loss was insignificant at 1 month ( p -value 0.272 for OAE and p -value 0.634 for AABR) and also insignificant at 3 and 6 months ( p -value 0.679 for AABR, for both). The association between gestational mild COVID-19 infection during gestation and neonatal hearing loss is statistically insignificant at initial screening as well as sequential screenings.

SARS-CoV-2, the responsible virus for the COVID-19 pandemic, has demonstrated neurotropic properties indicated by cases presenting with auditory and vestibular system insults. The expression of ACE-2 receptors in the placenta and the detection of IgM antibodies against the virus in the fetuses of pregnant women suffering from COVID-19 render vertical transmission of the infection to the fetus possible. Thus, our study aims to examine whether, similar to other viruses like CMV, SARS-CoV-2 is responsible for congenital hearing loss. This is a retrospective study in a regional pediatric hospital.

For the study period, nine mothers were found positive during the first trimester, twenty mothers in the second trimester, and eighty-three mothers in the third trimester. TEOAEs test and AABR test scored PASS bilaterally in all neonates tested. Conclusion : Infection with COVID-19 during pregnancy was not a risk factor for hearing loss, similar to other studies. What is known: • The pathogenetic mechanism of the viral-induced impairment of the organ of Corti includes direct damage to the hair cells and indirect damage due to the induction of the innate inflammatory response. • Early data suggested that the SARS-CoV-2 virus also has neurotropic properties with manifestations from the sensory epithelia. What is new: • Although the intrauterine infection remains controversial, the expression of the ACE-2 receptor on the placenta and the detection of IgM antibodies, as well as the covid-19 genome in fetuses, make the vertical transmission tenable. • In our study, the newborn hearing screening results indicate that COVID-19 infection during pregnancy is not a risk factor for hearing loss.
