SARS‐CoV‐2 infection as cause of in‐utero fetal death: regional multicenter cohort study

Ultrasound in Obstetrics &Gynecology, Volume 62, Issue 6, Page 867-874, December 2023., 2023
ABSTRACT Objective Placental infection with severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) can lead to placental insufficiency and in‐utero fetal death (IUFD). The objective of this study was to confirm and quantify the extent to which fetoplacental infection with SARS‐CoV‐2 is a cause of fetal death.

Accounting for bias in prevalence estimation: The case of a globally emerging pathogen

Journal of Applied Ecology, Volume 60, Issue 9, Page 2007-2017, September 2023., 2023
These results highlight the importance of using robust inferences to inform disease risk assessments and to efficiently allocate limited resources during mitigation strategies of infectious diseases. The methods used here can be applied to a wide range of host–pathogen systems, and will be of interest to both researchers and practitioners aiming to ...
