The paper presents a retrospective analysis of structure and trends in infectious diseases spreading in the Bulgarian armed forces (BAF) during the period 1997-2010. That period includes considerable changes in the strategic military goals, development of BAF, significant personnel reduction and transition from conscript to professional army. The survey is based on data from the periodic reports of the officially recorded infectious diseases cases and outbreaks in BAF during the investigated period. Regression analysis and the least squares approach are conducted to determine trends in infectious diseases incidence. Data show an upward trend in infectious diseases incidence, along with the BAF personnel downsize. The infectious diseases structure reveals the leading role of Influenza and Acute respiratory infections (ARI) - 38.3 % of the total burden of infectious diseases, followed by Enterocolitis (19.06 %), Hepatitis A (9.04 %), Mumps (5.01 %), Hepatitis B (3.45 %), Chickenpox (3.16 %), Rubella (2.65 %), Shigellosis (1.62 %), Hepatitis C (1.54 %), Foodborne illnesses (1.51 %), L yme borreliosis (1.0 %) etc. Upward trends in diseases incidence are observed for Influenza and ARI, Enterocolitis, Mumps, Chickenpox and Lyme borreliosis. Downward trends are found for all types of viral hepatitis, Rubella, Shigellosis and Foodborne illnesses.
