Abstract
Hantavirus disease is an anthropozoonosis caused by a hemorrhagic
fever virus. In Western Europe, the etiologic agent is Puumala virus
whose main vector is the red bank vole (Clethrionomys glareolus).
Hantaviral outbreaks are chiefly observed in woodlands and during years
with dense local population of bank voles, increasing the risk of direct
or indirect contact with men. In these rodents, infection is not
associated with clinical signs. Infectious viruses present in saliva,
urine and feces are transmitted by aerosol or bites. The percentage of
infected bank voles and the occurrence of disease in men are closely
related to the rodent population size. Hantavirus disease mainly occurs
in autumn and spring: this seasonality is partly due to changes in the
size and structure of bank voles communities. Human activities are also
implied in hantavirus disease appearance. Each serotype has its specific
main rodent reservoir. However other species may secondarily carry the
virus. In domestic animals, cats and swines are the only recognized
positive species for hantavirus in Western Europe.
