Active v. passive surveillance for malaria in remote tribal belt of Central India: Implications for malaria elimination.

Comparison of the results of two methods revealed that ACD (active case detection) in villages provides relatively large numbers of malaria positive cases (1408/3601) as compared to PCD (passive case detection) at CHC (139/2743) (OR 12.
