Breastfeeding in Mothers with COVID-19: Insights from Laboratory Tests and Follow-Up from Early Outbreak of the Pandemic in China.

Objective: The outbreak of Coronavirus Disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) threatens a surging number of community groups within society, including women actively breastfeeding. Breastfeeding involves intimate behaviors, a major transmission route of SARS-CoV-2, and is integral to the close mother-baby relationship highly correlated with maternal psychological status. Materials and Methods: Twenty-three pregnant women and puerperae with either confirmed or suspected diagnoses of COVID-19 were enrolled in the study. The clinical characteristics and outcomes of the mothers and neonates were recorded. The presence of SARS-CoV-2, IgG, and IgM in breast milk, maternal blood, and infant blood, together with feeding patterns, was assessed within 1 month after delivery. Feeding patterns and maternal psychological status were also recorded in the second follow-up. Results: No positive detection of SARS-CoV-2 was found in neonates. All breast milk samples were negative for the detection of SARS-CoV-2. The presence of IgM for SARS-CoV-2 in breast milk was correlated with IgM presence in the maternal blood. The results of IgG detection for SARS-CoV-2 were negative in all breast milk samples. All infants were in a healthy condition in two follow-ups, and antibody tests for SARS-CoV-2 were negative. The rate of breast milk feeding increased during two follow-ups. All mothers receiving a second follow-up experienced negative psychological factors and status. Conclusions: Our findings support the feasibility of breastfeeding in women infected with SARS-CoV-2. The additional negative psychological status of mothers due to COVID-19 should also be considered during the puerperium period.

Vulnerability and resilience in the wake of COVID-19: family resources and children’s well-being in China

The present study uses data from a 2020 survey conducted in Shaanxi Province during the COVID-19 outbreak to examine the family resources and psychological well-being of four major groups of Chinese children (urban, migrant, rural nonmigrant, and rural left-behind children). The results highlight the complex ways in which family resources intersect with the pandemic to affect these different groups of children. Family economic resources have generally declined across all groups, but left-behind children have suffered the most severe economic shock. However, parent–child relationships for all children have improved across the board during the pandemic. Diminished economic resources act as a risk factor, while improved family relationships play a protective role in children’s psychological well-being. Parent–child relationships have had a more pronounced positive impact on psychological outcomes for migrant and left-behind children, who are the most deprived of parental input under normal circumstances, than for other groups of children. Because of these processes, migrant children and left-behind children fare similarly to urban children in terms of their resilience to the COVID-19 crisis. Among children enjoying especially favorable parent–child relationships, migrant children and left-behind children even appear to have higher psychological well-being than urban children during the pandemic. In comparison to this social impact, the impact of family economic resources is more moderate in magnitude and does not vary systematically across different groups of children. As a result, the positive impact of improved parent–child relationships largely outweighs the adverse effect of reduced family economic resources. Overall, the findings provide new insight into the relationship among disasters, family resources, and child well-being in the context of the COVID-19 crisis in China.

First study on surveillance of SARS-CoV-2 RNA in wastewater systems and related environments in Wuhan: Post-lockdown (preprint)

Wastewater-based epidemiology (WBE) has emerged as an effective environmental surveillance tool in monitoring fecal-oral pathogen infections within a community. Congruently, SARS-CoV-2 virus, the etiologic agent of COVID-19, has been demonstrated to infect the gastrointestinal tissues, and be shed in feces. In the present study, SARS-CoV-2 RNA was concentrated from wastewater, sludge, surface water, ground water, and soil samples of municipal and hospital wastewater systems and related environment in Wuhan during the COVID-19 middle and low risk periods, and the viral RNA copies quantified using RT-qPCR. From the findings of this study, during the middle risk period, one influent sample and three secondary treatment effluents collected from Waste Water Treatment Plant 2 (WWTP2), as well as two influent samples from wastewater system of Hospital 2 were SARS-CoV-2 RNA positive. One sludge sample collected from Hospital 4; which was obtained during low risk period, was positive for SARS-CoV-2 RNA. These study findings demonstrate the significance of WBE in continuous surveilling and monitoring of SARS-CoV-2 at the community level, even when the COVID19 prevalence is low. Therefore, the application of WBE is principally useful in tracking the level of infections in communities and the risk assessment of the secondary environment.
