Title: Analysis of results in monitoring of hemorrhagic fever with renal syndrome in Yunnan Province in 2006
Abstract: Objective To understand the epidemiological characteristic of hemorrhagic fever with renal syndrome (HFRS) in Yunnan Province for offering a scientific reference. Methods The data of HFRS infections in Yunnan were collected; human sera and lung tissue and sera of rodents in the monitoring counties were sampled and assayed for detecting antibody and antigen of hantavirus. Results The 39 cases and 1 deaths had been reported in Yunnan in 2006 wih incidence of 0.05/100,000 and the case fatality rate of 2.56%. The main prevalent areas were in Dali prefecture, Kunming city and Honghe prefecture. The latent infection rate was 6.90% in population in the prevalent areas. There 810 rodents belonged to 10 species were captured in monitoring counties of Luxi, Xundian and Yongshen. The rodents of Rattus norvegicus and Rattus flavipectus were the dominant species in human dwelling areas. the rodents of Apodemus agrarius and Apodemus draca and Eothenomys miletus were the dominant species in the fields. The hantavirus-carrying rate was 4.13% in rodents. Hantovirus was detected from Rattus norvegicus, Rattus flavipectus,Apodemus agrarius. Apodemus draca and Eothenomys miletus. Conclusion There are the foci mainly with the domestic hosts of Rattus norvegicus and Rattus flavipectus. There are also foci mainly with campestral hosts of Apodemus agrarius and Apodemus draca and Eothenomys miletus in the monitoring areas. Thus effective measures be taken including vacination and elimination of rodents ine for control HFRS.
