The hantavirus incubation period -- the time between infection and first symptoms -- isn't known for sure. The dangers include many diseases that can be spread through their feces — from salmonella to Hantavirus — so cleaning up after an infestation is especially important. Anyone who comes into contact with rodents that carry Hantavirus is at risk of Hantavirus pulmonary syndrome (HPS).

Vole mating season can last from spring all the way through fall, but it usually ranges from late spring and ends in early fall. Once hantavirus particles attach to cell surface receptors by one, or both glycoproteins (1) they are uptaken by clathrin-mediated endocytosis (2a) or alternatively by other pathways that do not involve clathrin (2b). ... as would be expected for Arvicolinae-associated hantaviruses. The viral entry process is composed of virus attachment or absorption on susceptible cells, penetration and subsequent uncoating, which is the first step for hantaviral life cycle. However, the biological functions of NBV p17 in the viral life cycle, and its involvement in viral pathogenesis, remain unclear.
