Although prior studies of tuberculosis-preventive treatment (TPT) for pregnant people with human immunodeficiency virus (PPWH) report conflicting adverse pregnancy outcome (APO) risks, international guidelines recommend TPT for PPWH.

Throughout the COVID-19 pandemic, many jurisdictions established isolation centres to help reduce household transmission; however, few real-world studies support their effectiveness. We compared the risk of transmission among households where first cases used the Toronto Voluntary Isolation Centre (TVIC) compared to households receiving routine self-isolation guidance, prior to widespread vaccine availability.

Liver disease assessment is a key aspect of chronic hepatitis C virus (HCV) infection pre-treatment evaluation but guidelines differ on the optimal testing modality given trade-offs in availability and accuracy. We compared clinical outcomes and cost-effectiveness of common fibrosis staging strategies.

Most individuals on combination antiretroviral therapy (ART) have HIV plasma viral loads below the limit of detection. However, episodes of low-level viremia (LLV) are observed in subsets of individuals, risk factors and clinical significance of which remain debated.

Shigella sonnei has caused sexually transmitted enteric infections in men who have sex with men (MSM) in Vancouver. We recently observed a high rate of multidrug-resistant (MDR) S. sonnei bacteremia among persons experiencing homelessness (PEH). We aim to describe the wider epidemiology, clinical outcomes, and genomics of S. sonnei infections over time.

Fluoroquinolones are an important component of anti-tuberculosis treatment and identifying fluoroquinolone resistance is essential. We present the first survey of fluoroquinolone resistance in England from sequencing of over 16,000 unselected isolates. Fluoroquinolone resistance was 1.4% overall and 23.9% in multidrug-resistant TB. Routine sequencing allows resistance surveillance and should be widely adopted.

Tuberculosis (TB) incidence remains disproportionately high in people migrating to Canada and other low TB incidence countries, but systematic TB screening and prevention in migrants is often cost-prohibitive for TB programs. We aimed to develop and validate a TB risk prediction model to inform TB screening decisions in foreign-born permanent residents of Canada.

As COVID-19 is integrated into existing infectious disease control programs, it is important to understand the comparative clinical impact of COVID-19 and other respiratory diseases.

BIPOC (Black, Indigenous, and other People of Color) communities bear a disproportional burden of seasonal influenza hospitalizations in the United States.

Long-acting injectable cabotegravir plus rilpivirine (LA CAB/RPV) is currently US Food and Drug Administration (FDA)-approved and HIV treatment guideline-endorsed as a switch strategy for patients with HIV (PWH) who are virologically suppressed on oral ART without a history of treatment failure. Recent changes to the International Antiviral Society-USA (IAS-USA) and U.S. Department of Health and Human Services' (DHHS) Panel on Antiretroviral Guidelines recommend the consideration of LA CAB/RPV in select PWH with viremia who are unable to achieve suppression with oral ART due to suboptimal medication adherence. In this article, we review the existing data on this off-label use of LA CAB/RPV, discuss the motivations and specific caveats implicit in the guidelines change, and propose next steps in exploring this novel treatment in this vulnerable patient population.
