Summary:
A study in Chennai, India, between 2021 and 2025, revealed that leprosy cases, while generally stable, are persistently concentrated in industrial and border zones. Notably, these areas show higher rates of new cases among children, suggesting ongoing transmission linked to migrant populations. The study calls for targeted surveillance, workplace interventions, and community-driven approaches to better control leprosy in these high-risk urban settings.

Chennai Faces Leprosy Hotspots Linked to Migrant Workers: Study
CHENNAI, INDIA – December 11, 2025 – A new study published in the Tamil Nadu Journal of Public Health and Medical Research reveals persistent leprosy hotspots within Chennai, particularly in industrial zones and border areas. Researchers from the Directorate of Medical and Rural Health Services (Leprosy) found a disproportionately high number of new leprosy cases among children in these areas, suggesting ongoing transmission within migrant worker communities.
The study, which analyzed data from 2021 to 2025, found that while the overall rate of new cases remained relatively stable, specific zones recorded significantly higher numbers, particularly those with large industrial presence or located on the city’s periphery. Researchers identified Ambattur, Valsaravakkam, Manali, Madhavaram, Sholinganallur, and Perungundi zones as areas of concern.
“We are observing hidden cases of leprosy, especially in industrial and adjoining residential areas,” stated Dr. Sridevi Govindarajan, one of the study’s authors. “Most of the affected individuals are migrant workers. When we found new cases in some industries, we checked surrounding residential areas where many of these workers lived, and we found a larger number of child cases. The cases are linked to the migrant population, and the infection is spreading in places they lived.”
The study highlights that paucibacillary leprosy, an early stage of the disease, is more common among children. Multibacillary leprosy, a more severe and infectious form, accounted for over half of all detections.
The authors urge for a shift in leprosy control efforts, advocating for targeted surveillance in industrial hubs and border areas. This includes regular community-based screening, workplace interventions with health education and dermatological screenings for migrant workers, and integrating leprosy awareness into occupational health services. The study emphasizes that detection of leprosy in children should be considered a key indicator of ongoing transmission.
The research team calls for innovative, migrant-focused, and community-driven approaches to achieve sustained leprosy elimination goals within Chennai’s urban environment.
