Demonstrating a diagnostic test works is no longer enough. Clinicians and laboratories also need evidence on how to adopt it in everyday practice. Andrea Prinzi, PhD, MPH, SM(ASCP), explains how implementation science can help infectious disease and clinical microbiology teams turn evidence into routine care.

Long-acting cabotegravir plus rilpivirine (Cabenuva) achieved superior viral suppression vs daily oral antiretroviral therapy at 6months in treatment-experienced people with HIV and detectable viremia in the phase 3b CROWN trial.

In the phase 3 LIBERTY study, the investigational monoclonal antibody, VYD2311, had significantly fewer adverse events than an mRNA COVID-19 vaccine, and it did not blunt vaccine-induced neutralizing titers when the two were given together.

The monoclonal antibody, Brelovitug, met the combined virologic and ALT response end point at week 24 in AZURE-1, with 56% response on 300 mg weekly and 45% on 900 mg every four weeks. The manufacturer projects a potential US launch in the fourth quarter of 2027.

Serial bloodstream isolates from two critically ill London patients showed heteroresistance, CRZ1 escape mutations, and drug-induced polyploidy despite wild-type FKS1 and susceptible MICs.

Projected disease burden from declining childhood vaccine coverage shows increases in vaccine-preventable diseases. Benjamin Lopman, PhD, provides insights on how VaxImpactMap works and the potential long-term disease consequences of decreased immunization rates.

Approximately 12% of all new cases of cancer worldwide in 2024 were attributable to an infection, with most of the infections preventable or treatable before cancer develops.

After 2 adults died of West Nile virus in central North Carolina this month, this FAQ explains how the mosquito-borne virus spreads, who faces the greatest risk of severe neuroinvasive disease, and how clinicians can diagnose, manage, and help prevent infection when no vaccine or antiviral treatment exists.
