Malaria continues to be a cause of great suffering in tropical and sub-tropical regions of the world (Brabin, 1989). Currently, it is endemic in about 100 countries affecting 4% of world’s population. Malaria has been eliminated or effectively suppressed in several parts of the world in past decade but is now undergoing resurgence (Gilles, 1987). It is returning to areas from which it had been eradicated as well as spreading into new areas such as central Asia and Eastern Europe.
