[Surveillance on hemorrhagic fever with renal syndrome in Guizhou during 1984-2000].
OBJECTIVE
To explore the relations between different areas on hemorrhagic fever with renal syndrome (HFRS) in Guizhou.


METHODS
Various forms of infectious areas were surveyed continuously through epidemiologic surveillance system.


RESULTS
In fixed areas under surveillance system, the mean positive rate of HFRSV among Apodemus agrarius was 3.39%, comparing with Rattus norvegicus 1.61% in Apodemus infectious areas of Zunyi county, 3.19% in Rattus norvegicus, but no HFRSV of Apodemus agrarius was identified in Rattus infectious area of Shiqian county. Both Apodemus and Rattus infectious areas were relatively stabilized. In both banks of Luowang river, Kaiyang county, which had been identified as areas of infections for Apodemus in the eastern part, Rattus infectious area in the west, slow change was noticed. In 1983 - 1984 was not found in Apodemus agrarius HFRSV, however the infectious rate of HFRSV in Apodemus agrarius was 13.85% (Ag 1/65, Ab 8/65) in the western part of the province in 1995 - 1998.


CONCLUSIONS
Both Apodemus and Rattus infectious areas were stabilized but changed slowly. Mixed type and the result of mutual penetration were noticed.
