RESUMO

BACKGROUND: It is well established that pregnant persons with SARS-CoV-2 are at an increased risk for preterm birth, however, less is known about perinatal outcomes for neonates with intrauterine exposure to SARS-CoV-2. METHODS: Characteristics of 50 SARS-CoV-2 positive neonates born to SARS-CoV-2 pregnant persons positive between May 22, 2020, and February 22, 2021, in Los Angeles County, CA, were assessed. Pattern of neonate SARS-CoV-2 test results and time to positive test was analyzed. Objective clinical severity criteria were applied to assess neonatal disease severity. RESULTS: Median gestational age was 39 weeks with 8 (16%) neonates born preterm. Most (74%) were asymptomatic, while 13 (26%) were symptomatic from any cause. Four (8%) symptomatic neonates met criteria for severe disease, of which 2 (4%) were likely secondary to COVID-19. The other 2 with severe disease had more likely alternate diagnoses, and 1 of these neonates subsequently died at 7 months of life. Among 12 (24%) that were positive within 24 hours after birth, one was persistently positive and represented likely intrauterine transmission. Sixteen (32%) were admitted to the neonatal intensive care unit. CONCLUSION: In this case series of 50 SARS-CoV-2 positive mother-neonate pairs, we found that most neonates were asymptomatic regardless of when they tested positive during the 14 days after birth, that there was relatively low risk of COVID-19 associated severe disease, and that intrauterine transmission can occur in rare cases. Although short-term outcomes are mostly promising, more research is needed to study long-term consequences of SARS-CoV-2 infection in neonates born to positive pregnant persons.
