title: Prevalence of crimean-congo hemorrhagic Fever among high risk human groups.
abstract: BACKGROUND
  Crimean-Congo hemorrhagic fever (CCHF), an acute viral infection, is a zoonotic disease which is transmitted to humans by infected ticks, direct contact with fresh meat or blood of infected animals (usually domestic livestock), or direct contact with the blood or secretions of an infected person. Livestock handlers, skin processors, veterinary staff, livestock market workers, and other personnel engaged in jobs requiring some contact with animals and/or animal products are at high risk for CCHF. Most reported cases of this disease in Iran belong to butchers and slaughterhouse workers.
  
  
  OBJECTIVE
  We aimed to study the prevalence of CCHF in slaughterhouse workers and livestock handlers who were admitted to Boo-ali Hospital for treatment of CCHF.
  
  
  METHODS
  We evaluated all patients' files with confirmed CCHF admitted to Boo-ali Hospital in Zahedan, in southeastern part of Iran, during 1999-2011. Then, we examined the prevalence of disease among the high risk groups.
  
  
  RESULTS
  Out of 362 patients with CCHF (86% male, 14% female; with age range 12-78 years), 123 (34%) were slaughterhouse workers, 103 (28.5%) livestock handlers and farmers, 32 (9%) housewives, 7 (2%) students, 6 (1.9%) teachers, 4 (1.2%) military personnel, and other groups were workers with different employments.
  
  
  CONCLUSIONS
  The present study showed that CCHF is highly prevalent in high risk occupational groups in Zahedan, Iran. Further surveillance, teaching and prevention programs are recommended.
