Epidemiology of a tick‐borne viral infection: theoretical insights and practical implications for public health

The morbidity of tick‐borne encephalitis (TBE) varies yearly by as much as 10‐fold among the people of Western Siberia. This long‐term variation is dependent on many factors such as the density of the tick populations, the prevalence of TBE virus (TBEV) among sub‐adult ticks, the yearly virulence of the TBEV, and prophylactic measures. Here we highlight the role of small mammal hosts in the circulation of TBEV through the ecosystem. Refining classical models of non‐viremic horizontal transmission, we emphasize the recently understood fact that the physiological and immunological status of the small mammal hosts affects the tick and virus‐host interactions. In addition to its theoretical interest, our approach may lead to some practical improvements in the precision of epidemiological forecasts and perhaps in forestalling the severity of outbreaks of TBE, or, at least, in forewarning medical authorities and the general public of impending TBE outbreaks.

Seasonal Changes of Thermoregulation in the Mole Vole Ellobius talpinus

Seasonal changes of thermoregulation were studied in mole voles (Ellobius talpinus Pall.) from southern Siberia. Spontaneous fluctuations of body temperature were significantly higher in summer than in autumn. Standard deviations from average daily temperature of individuals were 0.95 ( \documentclass{aastex} \usepackage{amsbsy} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{bm} \usepackage{mathrsfs} \usepackage{pifont} \usepackage{stmaryrd} \usepackage{textcomp} \usepackage{portland,xspace} \usepackage{amsmath,amsxtra} \usepackage[OT2,OT1]{fontenc} \newcommand\cyr{ \renewcommand\rmdefault{wncyr} \renewcommand\sfdefault{wncyss} \renewcommand\encodingdefault{OT2} \normalfont \selectfont} \DeclareTextFontCommand{\textcyr}{\cyr} \pagestyle{empty} \DeclareMathSizes{10}{9}{7}{6} \begin{document} \landscape

In cold seasons, mole voles are able to maintain temperature homeostasis in a wide range of environmental conditions. This ability declined only in summer. Hence, the mole voles adaptation to the continental climate is based on distinct seasonal variations of thermoregulation. In summer, thermoregulatory mechanisms are similar to those of desert eusocial fossorial species, but in spring and autumn, mole voles share the thermoregulatory strategies of boreal terrestrial rodents.
