Hemorrhagic fever with renal syndrome, new questions for the study

In the work there are presented results of morbidity of Hemorrhagic fever with renal syndrome (HFRS) in the population of the Ulyanovsk region for 2003-2013 with the use of the epidemiological method on the establishment of a causal relationship to the number and infection rate of mouse-like rodents. The presented material shows that in besides well-known classical criteria exerting the influence on the epidemic process in HFRS there are others, in particular, an increasingly growing role of anthropogenic factors which are to subjected to the closer study in the system of epidemiological surveillance of the given infection. Observed by ourselves results, taking into account the number of mouse-like rodents and their infection rate with Hantavirus did not admit unambiguously for the last 11 years as determining in the development of the epidemic process of HFRS in the Ulyanovsk Region.
