Surveillance, Outbreak Response, and Tobacco/Vaping Prevention: Five Recent Studies
These five studies were selected because they speak directly to Mesa County Public Health’s priorities: strengthening local disease surveillance and outbreak response, improving community health data, and informing vaping and tobacco prevention efforts. Each study offers practical findings that can be applied to local monitoring, investigation, or communications activities.
Trends in Emergency Department Visits Involving Cannabis Hyperemesis Syndrome Identified Using a New Diagnosis Code – United States, January 2023-May 2026.
After a CHS-specific ICD-10-CM diagnosis code was introduced on October 1, 2025, CHS-coded ED visits increased sharply (about 3.7 times the preimplementation monthly average) and remained elevated through May 2026. Higher proportions were observed among persons aged 15–24 years and females; authors note the rise may reflect improved recognition and coding as well as possible true increases in cases.
Why it matters for Mesa County Public Health
For Mesa County Public Health’s syndromic surveillance and community health data program, this study highlights how coding changes and clinician recognition can produce abrupt shifts in ED-based indicators. Mesa County can use this example to review local ED coding practices, encourage routine cannabis-use assessment in acute care settings, and adjust baseline trend interpretations when a new code or clinical guidance is implemented.
Outbreak of Hepatitis A Linked to Frozen Blueberries, the Netherlands, 2024-2025.
An investigation of 24 hepatitis A cases in the Netherlands (Nov 2024–Feb 2025) identified frozen blueberries from a supermarket chain as the likely source after linking consumption data with detection of outbreak RNA in a food product. The report describes coordinated case detection, laboratory confirmation, and traceback to the implicated product.
Why it matters for Mesa County Public Health
This outbreak is a concrete example of foodborne hepatitis A detection, product testing, and traceback that local public health investigators may encounter. Mesa County Public Health can apply lessons on integrating epidemiologic, laboratory, and food-traceback data when responding to suspected foodborne hepatitis A, and consider implications for local vaccination outreach and communication to retailers and consumers.
Outbreak of Salmonella enterica Serovar Reading Linked to Dried Bovine Meat, New South Wales, Australia, 2023.
A Salmonella Reading outbreak in New South Wales was traced to a restaurant and to dried bovine meat products sold in South Asian grocery stores; the pathogen was isolated from food items and linked to an unlicensed meat processor. The investigation combined clinical isolates, food testing, and supply-chain traceback to identify the source.
Why it matters for Mesa County Public Health
The report underscores the role of food-product testing and supply-chain traceback in controlling foodborne outbreaks—activities that intersect with local environmental health and outbreak response functions. Mesa County Public Health can use this example to reinforce partnerships with local food safety inspectors, retail outlets, and laboratory partners when addressing suspected contaminated products, and to review outreach to specialty markets and small processors in the community.
Patterns and Correlates of Disposable E-Cigarette Use Among U.S. Youth.
Analysis of the 2023 National Youth Tobacco Survey found that youth who predominantly use disposable e-cigarettes have high rates of nicotine-containing product use (81.9%), prefer fruit flavors, and report greater daily social media exposure and severe psychological distress compared with nonusers. Concurrent use of cigarettes and e-cigarettes was associated with the strongest indicators of nicotine dependence and social exposure.
Why it matters for Mesa County Public Health
This study directly informs Mesa County Public Health’s vaping and tobacco prevention priority by identifying key risk factors—flavors, social media exposure, and peer/home use—among adolescents. Findings can help target school- and community-based prevention efforts, guide social media monitoring or counter-messaging, and prioritize interventions that address flavored disposable products and youth exposure pathways.
Examining Spontaneous Cognitive and Emotional Reactions to Messages About Very Low Nicotine Cigarettes (VLNCs).
Content analysis of open-ended reactions to messages about reducing nicotine in cigarettes found that pro-arguing and message acceptance were common and associated with greater support for nicotine-reduction policy and, among people who smoke, higher quit intentions. Negative emotions and message acceptance were also linked to subsequent behavior such as talking about quitting or making a quit attempt.
Why it matters for Mesa County Public Health
For Mesa County Public Health’s tobacco communications and cessation outreach, these findings emphasize that message framing and emotional/cognitive reactions predict policy support and quit-related behaviors. The county can use this evidence to test local messaging about nicotine reduction and cessation, select message elements likely to increase acceptance, and include measures of immediate cognitive/emotional responses in evaluation of outreach.
Across these studies, consistent themes are the value of timely, well-coded surveillance data and the importance of integrating epidemiology, laboratory evidence, and communications in outbreak response and prevention. Each paper offers actionable insights Mesa County Public Health can incorporate into monitoring, investigation, and targeted prevention efforts.
