title: Visceral leishmaniasis in North West Saudi Arabia: a new endemic focus of L. donovani or further evidence of a changing pathogenic role for L. tropica?
abstract: OBJECTIVE
  The objective of this study was to evaluate patients with VL from the city of Tabuk, Kingdom of Saudi Arabia, with particular reference to the possibility that a focus of VL exists in the North West Province of Saudi Arabia, an area where it had not previously been reported.
  
  
  METHODS
  North West Armed Forces Hospital, Tabuk, Saudi Arabia.
  
  
  METHODS
  Retrospective evaluation of all cases of infantile visceral leishmaniasis diagnosed in Tabuk, Saudi Arabia between 1989 and 1994.
  
  
  RESULTS
  5 cases of infantile visceral leishmaniasis were reviewed. In four cases, no evidence of travel outside Tabuk could be identified, suggesting primary infection by viscerotropic Leishmanial organisms in this area of Saudi Arabia.
  
  
  CONCLUSIONS
  Visceral leishmaniasis has been identified in an area previously not considered endemic for L. donovani. This observation may indicate either, a previously unrecognized focus of L. donovani or provide further evidence of a changing pathogenic role for L. tropica.
