Does the rise in local Hansen's disease cases concern you regarding your community's public health?
Florida health authorities have recorded two new cases of Hansen's disease, bringing the state's total for 2026 to 25. These latest infections were identified in Orange County and Polk County.
Why it matters
Understanding the transmission of Hansen's disease helps Floridians recognize potential risks, even though most of the population possesses a natural immunity to the bacteria that causes it.
The Florida Department of Health reports 25 total cases in 2026, compared to 36 cases throughout 2025. While 95% of the population is naturally immune to the bacteria, how these individuals contracted the disease remains under investigation.
The players
Florida Department of Health
The state agency responsible for public health surveillance and disease tracking.
Centers for Disease Control and Prevention
The federal agency that provides public health guidance and reports that 95% of people are naturally immune to the bacteria causing Hansen's disease.
The details
Hansen's disease is caused by bacteria that can spread through prolonged close contact with an infected individual. Exposure to contaminated soil or contact with nine-banded armadillos has also been linked to transmission in scientific studies. Because symptoms may take up to 20 years to manifest, infection sources are often difficult to pinpoint. The condition is treatable with an antibiotic regimen typically lasting one to two years.
Timeline
1992-2014: Florida averaged six cases of leprosy annually.
2015: Florida cases spiked to 29.
2025: State set a modern record with 36 cases.
Oct 3, 2026: Data cut-off for reported county-level cases.
Oct 15, 2026: Florida Department of Health released latest health data.
Health Landscape
The current 2026 case count follows a trend of elevated annual reporting that has persisted since the 2015 spike. This trajectory marks a significant departure from the lower case averages recorded in Florida between 1992 and 2014.
Given the potential for a long incubation period, any unexplained skin lesions should be discussed with a primary care physician. While the risk of infection is low for most people due to natural immunity, avoiding contact with nine-banded armadillos remains a recommended preventive step.
The takeaway
Hansen's disease is a rare but treatable bacterial infection that requires long-term antibiotic therapy. Monitor your skin for any unusual or persistent patches and consult a doctor if you have concerns about potential exposure history.
