Research briefing: Immunization, food safety, and surveillance — studies relevant to Hawaii State Department of Health
These five studies were selected because they intersect directly with Hawaii State Department of Health priorities: vaccination and kindergarten immunization monitoring, food-safety outbreak detection and recall enforcement, and surveillance approaches that support multilingual public communication and program access. Each paper offers recent evidence or programmatic lessons that can inform the Department’s immunization portal, outbreak response, and surveillance planning.
West Nile Virus and Other Nationally Notifiable Arboviral Diseases – United States, 2024.
CDC surveillance for 2024 showed 1,955 arboviral disease cases reported nationally, with West Nile virus (WNV) accounting for 92% of cases and 189 deaths overall. Cases were concentrated in older adults and during July–September; the report emphasizes timely surveillance, clinician consideration of arboviral testing during vector seasons, and the role of vector control and donor screening in reducing morbidity and mortality.
Why it matters for Hawaii State Department of Health
Hawaii DOH’s vector-borne disease and communicable disease surveillance programs can use the report’s seasonality and testing recommendations to refine local awareness campaigns and clinician guidance, including timing of messaging through the immunization portal and public meetings. The emphasis on timely surveillance and vector-control activities aligns with the Department’s responsibilities for mosquito monitoring and public health advisories.
Kudoa septempunctata Parasite-Associated Foodborne Disease Outbreaks, South Korea, 2015-2024.
National surveillance in South Korea found that Kudoa septempunctata foodborne cases declined sharply during COVID-19 and remained low through 2024, with evidence pointing to restaurant-based raw fish consumption as the principal transmission pathway. A reduction in affected municipalities was observed, supporting links between eating practices and outbreak distribution.
Why it matters for Hawaii State Department of Health
Given Hawaii’s seafood consumption and tourism-linked restaurant sector, these findings are relevant to the Department’s food safety oversight and recall-alert responsibilities; they highlight the importance of targeted inspections, restaurant-focused risk communication, and rapid notification when parasite-associated illnesses are identified. The study’s surveillance approach may inform Hawaii DOH protocols for monitoring seafood-associated signals and issuing multilingual recall or advisory notices.
Thirty years of hepatitis A epidemiology and vaccine studies: A narrative review of lessons learned in Alaska.
A review of Alaska’s hepatitis A (HAV) experience shows that routine early childhood HepA vaccination eliminated transmission in previously outbreak-prone areas; targeted one-dose vaccination during active outbreaks stopped transmission within 4–8 weeks in outbreak settings. Evidence indicates protection for most vaccinees for at least 25 years, though long-term durability beyond that remains less certain.
Why it matters for Hawaii State Department of Health
Lessons from Alaska are directly relevant to Hawaii DOH’s kindergarten immunization focus and its new online portal: they support considerations for routine HepA policy, rapid outbreak-dose strategies, and record verification workflows to detect susceptible children. These findings can inform operational planning with partner networks (including the West Coast Health Alliance) for vaccine outreach and verification of immunization status in school-entry populations.
Vaccination coverage among individuals receiving HIV pre-exposure prophylaxis (PrEP): A systematic review and meta-analysis.
This meta-analysis of 24 studies (13,087 individuals) found variable and often suboptimal vaccination coverage among PrEP users: HBV 73%, monkeypox 61%, HAV 59%, and HPV 43%, with substantial heterogeneity and frequent reliance on self-reported status. The authors identify missed prevention opportunities and recommend integrating vaccination into PrEP care pathways and strengthening provider engagement.
Why it matters for Hawaii State Department of Health
For Hawaii DOH, the paper highlights a population-level opportunity to improve adult vaccine uptake through clinical program integration—relevant to the Department’s adult immunization outreach and collaborative provider engagement efforts. Findings can inform targeted outreach, protocol development for vaccine offers in sexual-health settings, and multilingual educational materials to increase documented vaccine coverage in the state’s immunization portal.
Epidemiology of Kawasaki Disease After the COVID-19 Pandemic in Japan 2023-2024.
A nationwide Japanese survey found Kawasaki disease incidence rebounded after COVID-19 restrictions, with marked age-dependent patterns: older children showed larger declines during the pandemic and larger rebounds post-restriction than infants. The study supports age-stratified surveillance and investigation into differing exposure pathways by age.
Why it matters for Hawaii State Department of Health
These pediatric surveillance findings are relevant to Hawaii DOH’s kindergarten immunization and child-health monitoring responsibilities because they underscore the importance of age-stratified surveillance and preparedness for changing pediatric illness patterns post-pandemic. The results can help the Department calibrate outreach to schools and child-health providers and ensure multilingual communications and nondiscrimination accommodations are in place when pediatric surveillance findings prompt public guidance.
Across these studies the recurring themes are the value of timely, age- and setting-specific surveillance, integrating vaccination offers into varied care pathways, and ensuring clear, multilingual communications for outbreak alerts and immunization verification. Together they reinforce operational priorities for Hawaii DOH in surveillance, food-safety response, and immunization program delivery.
