Socio-Economic Inequities in the Age-Specific Burden of Severe Respiratory Syncytial Virus (RSV) in Canada, 2016-2019.

Background: Socio-economic status (SES) is an important determinant of severe respiratory infections. Despite being a leading cause of hospitalization, limited attention has been given to social inequities in respiratory syncytial virus (RSV), particularly outside of childhood and beyond neighbourhood-level measures. This study aimed to quantify the burden of severe RSV disease across the age continuum by individual-level SES indicators.

Large decrease in syringe distribution following the introduction of fentanyl in King County, Washington.

Background: Syringe services programs (SSPs) serve as key platforms to deliver harm reduction services to people who use drugs (PWUD). Changes in drug supply and drug consumption behaviors, particularly the increasing use of fentanyl through non-injection methods, may impact SSP utilization.

Material And Methods: We collected routine program data from three SSPs in King County, Washington.

Burden of Illness Associated With Respiratory Syncytial Virus, Influenza, and Coronavirus Disease 2019 in Infants and Young Children in Ontario, Canada, 2018-2023: A Population-Based Canadian Immunization Research Network Study.

Background: As severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transitions to endemicity and respiratory syncytial virus (RSV) and influenza reestablish their seasonal circulation patterns, understanding their comparative burden on infants and children can guide health system responses and funding priorities.

Methods: This was a population-based cohort study of children aged <5 years in Ontario, Canada, from September 2018 to August 2023 using linked health administrative databases.

Results: Seasonal cohorts comprised 731 838 to 763 660 children.
