Inferring Viral Transmission Pathways from Within-Host Variation

Date
Tuesday, October 24, 2023 - 4:00 AM
Description
Genome sequencing can offer critical insight into pathogen spread in viral outbreaks, but existing transmission inference methods use simplistic evolutionary models and only incorporate a portion of available genetic data. Here, we develop a robust

Impact of a vaccine passport on first-dose SARS-CoV-2 vaccine coverage by age and area-level social determinants of health in the Canadian provinces of Quebec and Ontario: an interrupted time series analysis

Date
Tuesday, October 24, 2023 - 4:00 AM
Description
BACKGROUND: In Canada, all provinces implemented vaccine passports in 2021 to reduce SARS-CoV-2 transmission in non-essential indoor spaces and increase vaccine uptake (policies active September 2021-March 2022 in Quebec and Ontario). We sought to

Initial and 5-day positivity rate of severe acute respiratory coronavirus virus 2 (SARS-CoV-2) polymerase chain reaction (PCR) in exposed inpatients within shared rooms during the omicron-variant dominant period

Date
Monday, October 23, 2023 - 4:00 AM
Description
In this observational study conducted in 2022, 12.3% of patients who shared a room with a patient positive for severe acute respiratory coronavirus virus 2 (SARS-CoV-2) also had a positive polymerase chain reaction (PCR) test, either at initial
