ABSTRACT
RESEARCH QUESTION: What is the trend of malaria and proportion of Plasmodium falciparum infections amongst troops of the Army units deployed in Assam over the last 5 years? STUDY DESIGN: Retrospective cross -sectional descriptive study. SETTING: Army units deployed in the state of Assam over the last 5 years. PARTICIPANTS: Population of army units deployed in the state of Assam over the last 5 years. STATISTICAL ANALYSIS: Percentage, Chi square. RESULTS: Malaria contributed to 3.60% to 7% of all hospital admissions over the period of 5 years. The overall malaria incidence showed a significantly increasing trend during the study period. (Chi square for linear trend = 5.19; P = 0.023). Out of these, P falciparum contributed 86% to 98%. The proportion of P falciparum infections showed a significantly increasing trend from 2005 to 2006. (Yate's corrected Chi square = 7.123; P = 0.008).
