Integrated surveys as a tool for early case detection in leprosy control programme.

Area of Science:

• Public Health
• Epidemiology
• Infectious Disease Control

Background:

• Leprosy remains a significant public health concern in rural areas.
• Early detection is crucial for effective leprosy management and prevention of disability.
• Previous leprosy surveys had limitations in reach and detection rates.

Purpose of the Study:

• To implement and evaluate an integrated survey approach for total leprosy case detection in Wardha District.
• To enhance the early detection of leprosy cases, particularly in rural populations.
• To assess the efficiency and effectiveness of utilizing a broader health workforce for leprosy surveys.

Main Methods:

• An integrated survey model involving various health workers (Leprosy Technicians, Sanitary Inspectors, etc.) was implemented.
• Non-leprosy health workers received 3-day training to suspect leprosy cases, with final diagnosis by Leprosy Technicians.
• Surveys were conducted in batches, with two integrated surveys annually over a defined period, alongside routine surveys.

Main Results:

• The integrated survey model enabled village coverage every two years, significantly faster than traditional methods.
• A case detection rate of 85.5% was achieved by the fourth survey, exceeding the estimated 70-75% from routine surveys.
• The program successfully identified leprosy patients in their early stages.

Conclusions:

• Integrated leprosy surveys utilizing a trained, multi-disciplinary health workforce are highly effective for comprehensive case detection.
• This approach substantially increases the case detection rate and accelerates the identification of early-stage leprosy.
• The findings support the scalability and efficiency of integrated health programs for infectious disease control in rural settings.
