title: [The recognition of the epidemic area of tsutsugamushi disease on Nan Peng Lie Island in China and the strategy of prevention].
abstract: OBJECTIVE
  To investigate the region for the epidemic area of tsutsugamushi disease.
  
  
  METHODS
  Epidemiological studies, Orientia tsutsugamushi isolation, and preventive measures were used.
  
  
  RESULTS
  The region belonged to epidemic area of south subtropical zone. The main host was found Rattus norvegicu. The main biological vector was Leptotrombidium deliens. The seasonal trends of the quantity of Rattus norvegicu and Leptotrombidium deliens were consistent with the incidence change of the disease in the region. Orientia tsutsugamushi has been isolated from Rattus norvegicu and Leptotrombidium deliens. Data showed that Orientia tsutsugamushi isolated strains mainly belongs to Karp. Sero-epidemiological data showed that antibodies of Orientia tsutsugamushi are 100.0% positive in the residents of the region and 4.0% in army men. After taking comprehensive preventive measures, the incidence was descending.
  
  
  CONCLUSIONS
  Nan Peng Lie island was proved an epidemic area of tsutsugamushi disease.
