[Morbidity and prophylaxis of hemorrhagic fever with renal syndrome in the Republic of Bashkortostan]. / O zabolevaemosti i profilaktike gemorragicheskoi likhoradki s pochechnym sindromom v Respublike Bashkortostan.

The brief retrospective analysis of morbidity, epizootological data and preventive measures with respect to haemorrhagic fever with renal syndrome (HFRS) during the whole period of its registration on the territory of the Republic of Bashkortostan along with the structure of HFRS morbidity during epidemic seasons of 1998 and 1999 is presented. The main causes of decreased HFRS morbidity in 1998, its rise in 1999 as well as prognosis for the year 2000 were detected. The level of HFRS morbidity among the population was found to be directly related to the number of rodents and their infection rate. The basic strategy of epidemic control interventions has been proposed.

[Effect of weather conditions in an epidemic season on the nature of the morbidity of hemorrhagic fever with renal syndrome]. / Vliianie pogodnykh uslovii épidemicheskogo sezona na kharakter zabolevaemosti gemorragicheskoi likhoradkoi s pochechnym sindromom.

The epidemic manifestation of the most active natural foci of HFRS in the USSR on the territory of Bashkiria is described. The authors compare two epidemic seasons of 1975-1976 and 1977-1978. Besides the number of rodents, the rise of morbidity is influenced by their early multiplication and weather conditions. The early appearance of the stable snow cover facilitates a rapid drop in the number of NFRS cases as early as in October, while prolonged autumn with rains, snow, periods of thaw and ice-covered ground leads to a rise in NFRS morbidity occurring in autumn and winter and ending only in March. Weather conditions also influence the epidemiological structure of morbidity.
