[Epidemiology and surveillance programs on hemorrhagic fever with renal syndrome in Mainland China, 2005 - 2008].

Abstract

The continuous descending trend of the HFRS epidemics could be related to the successful strategies on comprehensive prevention and control measures, as controlling the number of rodents and vectors, carrying out HFRS vaccination campaign and health education by the local health care takers in the recent years. Implementation of the new national Expanded Program of Immunization on HFRS vaccine in high-risk areas may further reduce the epidemics. However, both the density and the virus carried rate among the host animals remain high in some areas, together with the emergence of new epidemic areas, all call for more attention to be paid on the disease.
