title: A crimean - congo haemorrhagic Fever outbreak in northern balochistan.
abstract: OBJECTIVE
  To describe the clinical characteristics, epidemiology, predictors of fatal outcome (PFO), and management effects of Crimean-Congo haemorrhagic fever (CCHF) patients during an outbreak in Northern Balochistan.
  
  
  METHODS
  Descriptive study.
  
  
  METHODS
  Fatima Jinnah Hospital and Combined Military Hospital, Quetta, from June to October, 2001.
  
  
  METHODS
  Patients presenting with a fever of less than 2 weeks duration and bleeding manifestations were included. Clinical history was recorded and patients were placed on oral ribavirin, and hematological support. Diagnosis was established by PCR for CCHF or detection of CCHF specific IgM and IgG.
  
  
  RESULTS
  Eighty-four patients were received, 34 (40.5%) were suspected of suffering from classical CCHF. All 34 (100%) patients presented with a history of fever and bleeding (epistaxis, gum bleeding, melena or haematuria). Mean platelet count was 30 x 109/L and mean ALT (alanine transferase) was 288 U/L. Among fatal cases, the mean platelet count was 18.4 x 109/L and ALT was 781 units/L. PCR for CCHF viral RNA performed on 10 patients was positive in 3 (30%) patients. CCHF specific IgM and IgG was positive in 17.6% (6/34). Four patients were brought in moribund condition and expired before treatment could be started, 4 patients expired during treatment and 76.5% (26/34) were cured. The overall mortality was 23.5% (8/34). Main predictors of fatal outcome were ALT Z 150 units/L, activated partial thromboplastin time(aPT) Z 60 seconds, prothrombin time (PT) Z 34 seconds, aspartate transferase (AST) Z 200 units/L, platelets 20 x 109/L, and fibrinogen 110 mg/dL.
  
  
  CONCLUSIONS
  In this series of CCHF occurring in Northern parts of Balochistan, gastrointestinal tract bleeding was the worst prognostic factor associated with fatal outcome. Providing education to healthcare workers and at risk populations, hematological support, anti-viral drugs, and barrier nursing may help reduce mortality.
