The objective of this study was to assess whether vaginal secretions and breast milk of COVID-19 patients contain SARS-CoV-2 virus. In this case series of 13 pregnant women with COVID-19, we observed negative viral test results in vaginal secretion specimens, suggesting that a vaginal delivery may be a safe delivery option. However, additional research is urgently needed to examine breast milk and the potential risk for viral contamination.
