Dominica’s public health infrastructure has marked a key milestone with the launch of domestic Polymerase Chain Reaction (PCR) testing for leptospirosis at the National Laboratory under the Ministry of Health, Wellness, and Social Services. This development cuts the island nation’s reliance on overseas diagnostic services and represents a major step forward in strengthening local disease response capabilities.
In an official statement from the Ministry, health authorities confirmed that the new in-house testing capacity transforms the country’s ability to identify leptospirosis, a potentially severe bacterial infection that spreads through contaminated water, with greater speed and precision. Prior to this rollout, all samples from suspected leptospirosis cases had to be shipped abroad for testing, creating delays that slowed treatment and public health intervention.
With the newly implemented Molbio PCR testing platform now operational at the national lab, clinical teams can access real-time diagnostic results, a shift that directly enables faster administration of targeted treatment, improves patient prognosis, and allows public health teams to roll out containment measures rapidly to stop further transmission of the infection.
Lab Superintendent Eric Carbon, who leads the facility’s modernization push, framed the introduction of leptospirosis PCR testing as a watershed moment for the country’s laboratory services. “The Molbio Testing Platform has drastically expanded our national lab’s capacity to test for a range of high-priority diseases, including leptospirosis. We no longer have to send samples overseas for diagnosis, and real-time processing lets us deliver results in a fraction of the previous timeline. These are transformative improvements for our lab,” Carbon explained.
He added that the new capability underscores the lab’s growing ability to detect both emerging and re-emerging pathogens that pose risks to population health, filling a critical gap in Dominica’s disease surveillance network.
The launch of leptospirosis testing is just one component of a broader, multi-stage initiative to upgrade molecular diagnostics and disease surveillance across the entire country. Carbon confirmed that additional PCR testing services are already in the pipeline to further expand the lab’s testing footprint. In the coming phase, the lab will roll out PCR testing for vaccine-preventable diseases like measles, expand its gastroenteritis testing panel to include varicella, and add detection for respiratory syncytial virus (RSV) to its existing respiratory pathogen testing menu.
These new services will complement the lab’s already established PCR testing capabilities, which cover a wide range of high-risk pathogens: arboviruses including dengue, chikungunya, Zika, and Oropouche; respiratory viruses such as influenza and COVID-19; and other priority pathogens including monkeypox and tuberculosis.
Health officials emphasize that this steady expansion of PCR testing capacity reflects the Ministry of Health’s ongoing commitment to investing in cutting-edge diagnostic infrastructure and boosting the country’s overall preparedness to handle public health emergencies. To fully leverage the new capability, the National Laboratory is urging all clinical providers across the country to continue collecting and submitting specimens from any suspected communicable disease cases included in national surveillance programs. The lab has particularly highlighted the importance of testing samples from patients presenting with unexplained fevers, respiratory symptoms, rashes, and other conditions that signal potential public health risks.
With Atlantic hurricane season underway, Carbon also issued a public advisory warning that increased rainfall and standing water — common conditions during storm season — create ideal environments for leptospirosis transmission. He specifically called on farmers and other high-risk groups to take targeted precautions to lower their chance of exposure and infection.
Closing out the announcement, the Ministry of Health, Wellness and Social Services reaffirmed its long-term commitment to delivering accessible, high-quality diagnostic services through the National Laboratory. These investments, the ministry noted, support data-driven public health decision-making and advance the core mission of protecting the health and well-being of every resident of Dominica.
