title: Epidemiology of brucellosis in Al medina region, saudi arabia.
abstract: OBJECTIVE
  To evaluate the prevalence of brucellosis in the Al-Medina region of Saudi Arabia and to determine the related factors.
  
  
  METHODS
  A cross-sectional survey was carried out in 1997 with a random multistage cluster sampling of 500 households (4000 subjects). Tube Agglutination Test (TAT) and 2-mercapto-ethanol (2ME) analyzed blood samples.
  
  
  RESULTS
  The study revealed that the prevalence of brucellosis was 2.6%. The prevalence was shown to increase with age in rural communities and low socio-economic status. There are eight predisposing factors associated with brucellosis. These are the consumption of raw milk, and milk products, the keeping of livestock, milking of livestock, animal contact, butchering of raw meat, handling parturient animal and contact with placenta membrane. The overall prevalence of brucellosis among livestock as assessed by examining blood from a random sample of animals was estimated at 17.4%.
  
  
  CONCLUSIONS
  THE FINDINGS OF THIS WORK INDICATE THAT: (1) There is high prevalence of brucellosis in the Al-Medina region of Saudi Arabia. (2) Very little is being done to prevent or minimize infections. (3) Control and prevention of brucellosis in animals and humans should be the goal in Saudi Arabia
  
  
  CONCLUSIONS
  IT IS RECOMMENDED THAT: (1) the surveillance be strengthened; (2) there be strict adherence to hygienic practices on farms; (3) there be cooperation and joint supervision at the boundaries with neighboring countries; (4) there be health education.
