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).

Background: Foodborne infection is a major cause of illness and death worldwide, having long term effects on children’s growth; and considerable illness, heavily affecting healthcare systems. To investigate an outbreak of food poisoning which occurred in an officers’ mess.Methods: A retrospective cross-sectional descriptive study was carried out in the setting of an officers’ mess in an army unit. Standard statistical methods such as calculation of percentage and Chi square were utilized for analysis.Results: It was observed that seven (63.6364%) cases were amongst officers, 3 (27.2727%) cases were among ladies and 1 (9.0909%) case was amongst ORs. 100% cases occurred within 9 to 20 hours of consuming the food.Conclusions: A small scale outbreak of food poisoning occurred in an officers’ mess in a military establishment. Clinically the most likely causative organism was suspected to be Salmonella typhimurium. No microbiological confirmation could be carried out as no food sample was available for the same.

Background: Dengue is a rapidly spreading mosquito borne disease. Dengue is now endemic in 100 countries worldwide.Methods: Cross sectional descriptive study design was used by the workers. We The workers obtained detailed information from each reported case. Active case finding by surveys during the period of the outbreak, besides a detailed environmental survey was also carried out. Standard statistical tools like calculating relative risk and Chi square were utilised for data analysis.Results: In all 17 cases who fulfilled the case definition criteria were admitted in the month of September 2019. Out of these 16 (94.11%) were confirmed by NS 1 Antigen ELISA, while 01 (05.88%) was probable case. The first case reported on 08 Sep 2019, followed by a sudden spurt in the number of cases. The weekly epidemic curve is depicted in (Figure 1). There were no complications or fatalities. Detailed environmental assessment of the area revealed Aedes mosquito breeding in artificial containers of water. The house index of 7.06%, while the container index was 6.06%.Conclusions: The above study thus highlights the necessity of strict environmental monitoring by all authorities concerned in the country to prevent morbidity and mortality due to Dengue fever and other mosquito borne diseases. The menace of Dengue fever will continue till we learn to manage our solid waste properly, as Dengue is after all a man-made disease due to improper solid waste disposal.
