Evaluation of COVID-19 infection risk during US spring semester in-person teaching

The main objective of the study was to determine the rates of in-person schooling and understand the school-based mitigation measures that were modified over the semester.

Sexually dimorphic placental antibody transfer during SARS-CoV-2 infection

In a paper recently published in the journal Science Translational Medicine by Bordt et al. (October 19th, 2021), maternal SARS-CoV-2 infections are studied with particular regard to maternal-fetal antibody transfer and virus-induced placental interferon responses, finding a sexually dimorphic response that results in lesser antibody transfer to the male fetus.

Water and surface surveillance can detect 93% of school-based COVID-19 cases

A new study posted to the medRxiv* preprint server explores environmental surveillance of elementary school settings for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) through wastewater and surface samples monitoring. The researchers demonstrated that 93% of the COVID-19 cases in public elementary schools could be identified using this method.

N501Y mutation in SARS-CoV-2 Delta variant is key to breakthrough infections

A study in the Philadelphia area found that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants evolve to become more contagious and resistant to COVID-19 vaccines. In addition, depending on the sublineage, SARS-CoV-2 variants such as the Delta variant led to a three-fold increased risk for vaccine breakthrough cases.

SARS-CoV-2 delta variant generates infections more quickly than previous strains

Researchers in the UK have conducted a study suggesting that the B.1.617.2 (delta) variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19) – is transmitted more quickly than previously circulating variants.
