Background Between April and September 2020, there were <10 000 reported cases of COVID-19 in the Masovia district, Poland, and <1000 new cases daily in Poland. During this period, all new hospital admissions to a maternity unit of a teaching hospital in Warsaw were screened for the COVID-19 infection. This retrospective study presents the findings from the reverse transcription-polymerase chain reaction (RT-PCR) test for COVID-19. Material/Methods This study included 838 women admitted for delivery between April 20 and September 20, 2020. All the admitted women were assigned to a low-risk or a high-risk group for COVID-19 and underwent RT-PCR nasopharyngeal swab tests (GeneFinder™-COVID-19-Plus-Real Amp Kit. OSANG Healthcare Co., Ltd., Gyeonggi-do, Korea) for COVID-19. The testing protocol included repeated testing in case of inconclusive results or negative results in the symptomatic patients. The maternal and neonatal data from these cases were collected and analyzed. Results All of the 838 women tested negative for COVID-19. Two women (0.24%) were classified as high risk for COVID-19. For 4 (0.48%) women, the results were initially inconclusive and negative when repeated. One hundred and eighty-one (21.5%) women presented with comorbidities, and 60 (7.2%) women were ≥40 years old. Conclusions The findings from this study show that between April and September 2020, there were no cases of COVID-19 infections at the maternity unit of a teaching hospital in Warsaw, Poland. However, the infection rates for COVID-19 across Europe continue to change. Testing protocols have been developed and established for all hospital admissions and it is anticipated that testing methods will become more rapid and accurate.
