Research brief: actionable lessons for Denver public health preparedness, surveillance, and integrated prevention
These five studies were selected because they offer practical, evidence-based lessons for the Denver Department of Public Health and Environment’s priorities: emergency surge planning, infectious disease surveillance and outbreak control, and integration of preventive services into community-facing programs. Each article was chosen for clear operational implications that can inform Denver’s CHIP partnerships, overdose and behavioral-health–adjacent outreach, environmental health work, and emergency preparedness efforts.
Implementation of Alternate Care Facilities During Public Health Emergencies: A Qualitative Study.
This qualitative study synthesized published U.S. ACF experiences and interviews with subject-matter experts to identify recurrent successes and challenges in planning and operating alternate care facilities. Five themes emerged: need for flexibility and adaptability; strong partnerships with health systems, emergency management, and public health; resource availability challenges; executive leadership support; and clear site leadership structures. The study also found that affiliation with parent health systems, flexible operational models, and warm-closure strategies improved performance and reactivation readiness.
Why it matters for Denver Department of Public Health and Environment
The findings map directly to DDPHE’s emergency preparedness and response priority by highlighting operational elements the department coordinates or advises on—surge capacity planning, cross-sector partnerships, executive-level buy-in, and activation/closure protocols. Lessons about warm closures and affiliation with health systems can inform Denver’s ACF templates, mutual-aid agreements, and training scenarios used with city, state, and health system partners.
Vaccination coverage among individuals receiving HIV pre-exposure prophylaxis (PrEP): A systematic review and meta-analysis.
This systematic review and meta-analysis of 24 studies (13,087 individuals) found suboptimal vaccination coverage among people receiving PrEP: HBV ~73%, monkeypox ~61%, HAV ~59%, and HPV ~43%, with high between-study heterogeneity and frequent self-reported status. Authors conclude these are missed prevention opportunities and recommend stronger integration of vaccination into PrEP care pathways and proactive provider engagement. The paper calls for standardized methods and evaluation of interventions to improve uptake.
Why it matters for Denver Department of Public Health and Environment
Although not specific to overdose programs, the study underscores a broader programmatic principle relevant to DDPHE’s CHIP and behavioral-health engagement priorities—integrating preventive services (vaccination) into existing care and outreach touchpoints to reduce missed opportunities. For Denver, this supports considering vaccination linkage strategies in partnerships with community clinics, sexual-health providers, harm-reduction sites, or other venues that reach priority and hard-to-reach populations.
Thirty years of hepatitis A epidemiology and vaccine studies: A narrative review of lessons learned in Alaska.
This narrative review of hepatitis A experience in Alaska documents that routine early childhood HepA vaccination eliminated community transmission in previously outbreak-prone areas and that single-dose reactive vaccination in outbreaks stopped transmission within 4–8 weeks. The review also reports evidence of vaccine-induced protection lasting at least 25 years for most individuals, while noting gaps in long-term durability data for those vaccinated in early childhood.
Why it matters for Denver Department of Public Health and Environment
The Alaska experience offers evidence for rapid, targeted vaccination strategies and long-term prevention planning that Denver can apply during local HAV outbreaks or when updating immunization priorities within the CHIP. The demonstrated effectiveness of single-dose reactive campaigns and durable protection can inform Denver’s outbreak response protocols, vaccine stockpile decisions, and communication with community partners about rapid vaccination deployment.
Outbreak of Salmonella enterica Serovar Reading Linked to Dried Bovine Meat, New South Wales, Australia, 2023.
This outbreak investigation in New South Wales linked Salmonella Reading cases to a restaurant and commercially distributed dried bovine meat products; isolates were recovered from the product and tracing led to an unlicensed meat processor. The report emphasizes epidemiologic traceback, product testing, and regulatory enforcement as key steps to stop transmission and prevent further distribution.
Why it matters for Denver Department of Public Health and Environment
The case provides concrete, transferable lessons for Denver’s environmental health and foodborne illness response work—specifically methods for rapid traceback, when to pursue product testing, and coordination with licensing and enforcement partners. Those operational lessons can help refine local investigation checklists, inspectorial priorities, and cross-agency communication protocols used during foodborne outbreaks.
Detection of Dengue Virus in Aedes aegypti Mosquitoes, Dubai, United Arab Emirates.
A one-year vector surveillance program in Dubai collected 1,598 Aedes aegypti and detected dengue virus in five pooled samples, confirming local mosquito infection after a 2024 outbreak. The study underscores the value of sustained entomologic monitoring—even in arid urban settings—to detect viral circulation and inform public-health response.
Why it matters for Denver Department of Public Health and Environment
While dengue is not currently endemic in Denver, this study highlights transferable surveillance principles relevant to DDPHE’s environmental health and emergency preparedness priorities: sustained, routine vector monitoring, targeted pool testing, and integrating entomologic data into situational awareness. These approaches can strengthen Denver’s preparedness for emerging vector-borne threats, guide resource allocation for surveillance, and support coordination with state and federal partners.
Across these studies, common themes are the value of pre-established partnerships and leadership, routine surveillance and readiness (including surge-capacity plans and vector/product monitoring), and integrating prevention services into existing community-facing programs. These operational levers align with Denver’s CHIP, overdose prevention, and environmental preparedness priorities and can guide targeted updates to planning, training, and cross-sector coordination.
