This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
Purpose:
We aimed to describe the outcomes, focusing on the hearing and neurological development, of children born to mothers with SARS-CoV-2 infection during pregnancy, and to evaluate the persistence of maternal antibodies in the first months of life.Methods:
An observational, prospective study at a tertiary hospital in Madrid (Spain) on infants born to mothers infected with SARS CoV-2 during pregnancy between March and September 2020. A follow-up visit at 1-3 months of age with a physical and neurological examination, cranial ultrasound (cUS), SARS-CoV-2 RT-PCR on NPS and SARS-CoV-2 serology were performed. Hearing was evaluated at birth through the automated auditory brainstem response and at six months of age through the auditory steady-state response. A neurodevelopmental examination using the Bayley-III scale was performed at 12 months of age.Results:
Of 95 infants studied, neurological examination was normal in all of them at the follow-up visit, as was the cUS in 81/85 (95%) infants, with only mild abnormalities in four of them. Serology was positive in 47/95 (50%) infants, which was not associated with symptoms or severity of maternal infection. No hearing loss was detected and neurodevelopment was normal in 96% of the children (median Z score 0).Conclusions:
In this cohort, the majority of infants born to mothers with SARS-CoV-2 infection during pregnancy were healthy children with a normal cUS, no hearing loss and normal neurodevelopment in the first year of life. Only half of the infants had a positive serological result during the follow-up.
