title: Epidemiology of HIV/AIDS in the East Azerbaijan Province, Northwest of Iran.
abstract: BACKGROUND
  This study was performed in response to the rapid propagation of HIV/AIDS across Iran and its status in this region. Accordingly, an evidence-based program is required to combat this disease.
  
  
  OBJECTIVE
  The present study estimated the prevalence of HIV/AIDS in East Azerbaijan (population: 3,724,000).
  
  
  METHODS
  We created a database of all positive cases from 1987 to 2012. We also analyzed and described the epidemiological status of HIV/AIDS during a 25-year period by using SPSS.
  
  
  RESULTS
  In East Azerbaijan, 371 HIV/AIDS cases have been reported, i.e. 1 case per 10,000 population. The vast majority of reported cases (91%, n =338) were men, whereas only 9% (n = 33) were women. The mean age of patients was 30.8 ± 12.3 years. Unsafe drug injection (59%, n = 219) and sexual interaction (13%, n = 48) were the two major modes of HIV transmission. In addition, 7% (n = 25) of patients have been diagnosed with HIV, hepatitis B Virus, and hepatitis C virus simultaneously. Moreover, 60% (n = 205) of men were infected via drug injection, while 82% (n = 27) of women were infected via unprotected sexual interaction (P < 0.001).
  
  
  CONCLUSIONS
  The results indicate a rapid increase in the number of HIV/AIDS cases in East Azerbaijan, necessitating immediate attention and strategies to combat the rapid spread of the disease. Development of provincial and national HIV/AIDS strategies demands more accurate and comprehensive HIV/AIDS surveillance.
