Antepartum SARS-CoV-2 infection and adverse birth outcomes in South African women.

Background: SARS-CoV-2 infection in pregnant women has been associated with severe illness in the women and higher rates of premature delivery. There is, however, paucity of data on the impact of the timing of SARS-CoV-2 infection and on symptomatic or asymptomatic infections on birth outcomes. Data from low-middle income settings is also lacking.

Active Intrapartum SARS-CoV-2 Infection and Pregnancy Outcomes.

Objective: Severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection during pregnancy has been associated with poor pregnancy outcomes. There is, however, not much information on the impact of the timing of SARS-CoV-2 infection on pregnancy outcomes, and studies from low-middle income settings are also scarce.

Study Design: We conducted a cross-sectional study from April to December 2020, in South Africa, to assess the association of SARS-CoV-2 infection on a nasal swab at the time of labor with fetal death, preterm birth, low birth weight, or pregnancy-induced complications.

Whole-Genome Sequence of Salmonella enterica subsp. enterica Serovar Typhimurium Strain WG49 and Escherichia coli Strain WG5 Used in South Africa for Phage Detection in Water Samples.

subsp. serovar Typhimurium WG49 is widely used for enumeration of F-specific RNA (F-RNA) coliphages in water. WG5 is broadly used for the detection and enumeration of somatic coliphages in water samples.
