USVI gains national standing with new disease tracking system

The U.S. Virgin Islands Department of Health has completed a major upgrade to how it tracks and responds to disease threats, implementing the National Electronic Disease Surveillance System Base System and becoming one of the nation's first jurisdictions to deploy the CDC-supported technology.

The new platform accelerates how the Epidemiology Division collects and analyzes reports from hospitals, laboratories and healthcare providers, Health Commissioner Justa Encarnacion said in a statement released Tuesday. The faster processing enables quicker identification of health risks and disease patterns across the territory.

"Strong public health begins with strong data," Encarnacion said. "This investment gives our epidemiologists better tools to identify health threats, track disease trends and respond more quickly when our communities are at risk."

The system modernization has drawn peer-reviewed attention in JMIR Medical Informatics, which documented the department's rollout of NBS 7 and its use of cloud infrastructure to bolster surveillance capacity in the islands.

Dr. Esther Ellis, the territory's lead epidemiologist and head of the Epidemiology Division, outlined how the upgrade works: it speeds up and strengthens disease reporting, deepens ties with clinical and lab partners, keeps public health data under local management and enables faster action during health emergencies.

"This modernization effort represents years of collaboration and innovation," Ellis said. "It strengthens our ability to monitor diseases, identify emerging health threats and provide public health leaders with the information they need to make timely, evidence-based decisions that protect our communities."

The system positions the territory to spot outbreaks sooner, track illness patterns and launch swift interventions to shield residents.

The Epidemiology Division has also built a track record in peer-reviewed research across disease surveillance, outbreak response, environmental health, substance-use patterns and animal health. A recent CDC publication documented Legionnaires' disease cases tied to two local hotels, strengthening the territory's environmental and prevention response. Wastewater testing uncovered cocaine, fentanyl, methamphetamine, amphetamine, xylazine and nicotine across the islands, yielding data to guide substance-use planning. A separate study of local bat populations found no rabies virus, adding to Caribbean wildlife knowledge.

Encarnacion framed the research portfolio as proof that success extends beyond direct services. "Every study we conduct, every new approach we develop and every improvement we make to our public health system helps us better understand the challenges we face and strengthens our ability to protect the people of the Virgin Islands," she said.

The department plans further investment in data systems, surveillance tools, emergency readiness and research, moves designed to sharpen decision-making and fortify the territory's capacity to handle emerging health threats.
