[Dynamics of hantavirus detection in the excretory organs of Apodemus mice and its relation to epidemic manifestations of hantavirus infection].

This paper presents data on the detection of hantavirus in the excretory organs of Apodemus mice which are natural carriers of pathogenic hantaviral serotypes in the Primorye Region. Acute infection periods were detected in naturally infected rodents with the highest hantavirus dissemination to the environment in different phases of rodent population cycles. There was a relationship between the rise of morbidity and the seasonal manifestation of hemorrhagic fever with renal syndrome morbidity and activity of hantavirus reproduction in the murine excretory organs.

[Time course of changes in antibodies of various avidity in murine rodents in the epizootic and epidemic processes in hantavirus infection].

The paper presents the results of studying the time course of changes in antibodies of varying avidity in murine rodents. The presence of low-avidity antibodies is shown to reflect the status of acute infection in the rodent population and their active viral shedding. A relationship is shown between the detection of low-avidity antibodies in animals in spring and autumn and the rise of endemic hemorrhagic fever (EHF) morbidity.
