New Evidence Questions Endemic Chagas Disease Transmission in the U.S.
Key Highlights
Medicine · Infectious Diseases
A review by Cantey et al. published in *Emerging Infectious Diseases* finds insufficient evidence to support the existence of endemic Chagas disease transmission in the United States. The analysis examined surveillance data and epidemiological patterns, concluding that locally acquired cases remain exceptionally rare and are not indicative of established transmission cycles. For researchers working on HIV/AIDS and AIDS-related comorbidities, this distinction is critical because it informs risk assessment for immunosuppressed populations who may be at higher risk for severe Chagas disease reactivation.

A correction published in *The Lancet Infectious Diseases* refines data from the NIRSE-GAL study, which evaluated universal nirsevimab prophylaxis in infants across two respiratory syncytial virus (RSV) seasons in Galicia, Spain. The corrected analysis adjusts the relative reduction in weekly incidence of all-cause first recurrent hospitalisation to −16·0% (–27·8 to −2·3) at 18 months follow-up. Although this is a correction, the study remains highly relevant to infectious disease researchers, including those focused on HIV and COVID-19, as it provides real-world evidence on the population-level impact of monoclonal antibody prophylaxis against a major respiratory pathogen in vulnerable paediatric populations.

A clinical case report in *Clinical Infectious Diseases* describes a 67-year-old immunocompromised male in Manitoba, Canada, who presented with right upper-quadrant abdominal pain and hepatic lesions following an allogeneic stem cell transplant. The patient’s dog, which hunted rodents, raises the possibility of zoonotic transmission of an infectious agent, though no travel history was reported. For investigators focused on HIV/AIDS and mucosal immunology, this case underscores the importance of considering atypical opportunistic infections in immunocompromised hosts and the potential role of environmental exposures in disease pathogenesis.
