title: [Study on the geographic distribution and serological typing of HFRS in Hebei Province].
abstract: Surveillance on the HFRS had been carried out during the period of 1986-1993. Rodent density ranged from 4.6%-12.2% with R.norvegicus exceeding 60% in all kinds of rodents. HV antigen carrier rate of R.norvegicus was 1.3%-7.5%, much higher than that among other rodents. A significantly positive correlation had been observed between the HFRS morbidity and the R.norvegicus density. Of 129 specimens from HFRS patients, 89% belonged to the type of SEOV. In the eastern and centre Parts of Hebei plain, HTNV occupied 1.6%. A total number of 9,609 HFRS patients had been identified during the period of 1980-1993. The plain area in Hebei province was recognized as the major epidemic area. The key measure for decreasing the HFRS morbidity was deratizationin in the residential area in January and February and immunization with HFRS inactivated vaccine.
