New strategies for active finding of leprosy cases in the Amazonian region.

INTRODUCTION
The use of the Self-Image Form (SIF) expands the identification of active leprosy cases to neighbors of index cases.


METHODS
The SIF was used to screen two groups: case (neighbors of index cases of leprosy) and control (individuals residing next to houses without leprosy) group. A specialist investigated suspected leprosy cases for disease confirmation.


RESULTS
New cases of leprosy were diagnosed in the case group (n = 7, 8.6%), but not the control group.


CONCLUSIONS
The new surveillance strategy is inexpensive, efficient, and feasible within a primary health strategy. Future studies can help improve the use of the SIF.
