AbstractThroughout the course of the ongoing SARS-CoV-2 pandemic there has been a need for approaches that enable rapid monitoring of public health using an unbiased and minimally invasive means. A major way this has been accomplished is through the regular assessment of wastewater samples by qRT-PCR to detect the prevalence of viral nucleic acid with respect to time and location. Further expansion of SARS-CoV-2 wastewater monitoring efforts to include the detection of variants of interest / concern through next-generation sequencing have enhanced the understanding of the SARS-CoV-2 outbreak. In this report we detail the results of a collaborative effort between public health and metropolitan wastewater management authorities and the University of Louisville to monitor the SARS-CoV-2 pandemic through the monitoring of aggregate wastewater samples over a period of 28 weeks. Our data indicates that wastewater monitoring of water quality treatment centers and smaller neighborhood-scale catchment areas is a viable means by which the prevalence and genetic variation of SARS-CoV-2 within a metropolitan community of approximately one million individuals may be monitored. Importantly, these efforts confirm that regional emergence and spread of variants of interest / concern may be detected as readily in aggregate wastewater samples as compared to the individual wastewater sheds.

Future Management

Awareness of SARS-COV-2 IgG may contribute to the management of asymptomatic RT PCR COVID-19 positive pregnant women, their newborns, and future vaccination practices. Objective: Characterize COVID testing results of asymptomatic COVID-19 positive pregnant women and their infants. Our assumption/hypothesis maintained that all infants born to asymptomatic COVID-19 positive mothers would have detectable SARS-CoV-2 specific IgG. Study Design: Retrospective chart review. Clinical demographics/COVID-19 testing of maternal/infant dyads were reviewed/collected for reporting purposes. Setting: Center for Women and Infants (CWI), University of Louisville Hospital, Louisville, KY Participants: Asymptomatic COVID-19 positive pregnant women/infant dyads admitted to the CWI between June 2020 to February 2021. Results: 36 COVID-19 positive asymptomatic mother/37 infant dyads (one set of twins) reviewed. 38% of the mother/infant dyads were positive for SARS-CoV-2 IgG, while 27% of mother/infant dyads were negative for IgG. A COVID-19 positive mother of twins was IgG negative, but both twins were positive. Two mothers in this study group had developed significant COVID-19 disease at 28w4d gestation and 34w0d gestation. Both required intensive care but recovered, and their pregnancies were maintained until 37w4d and 39w3d gestation, respectively. By the time of delivery, both mothers had negative COVID-19 RT PCR testing, but both infants were positive for SARS-CoV-2 IgG antibodies. COVID-19 RT PCR testing on both of these infants at 24 and 48 hours of age was negative. Conclusion: SARS-CoV-2 IgG is passively transferred to the infant during pregnancy of asymptomatic positive COVID-19 mothers however appears variable and/or possibly based on the ability of IgG detection with current testing. Further investigation of the immune system’s response to the SARS-CoV-2 virus during pregnancy can direct future management/treatment during pregnancy, especially in the wake of vaccination for the virus during pregnancy and emerging variants.
