Hantavirus poses a significant health risk, with a fatality rate as high as 50% for some strains. While human-to-human transmission is rare and limited to specific strains like the Andes virus, the presence of infected rodents increases the likelihood of exposure, particularly in areas where humans encroach on rodent habitats. Drier climates and higher temperatures, as seen in western states, can exacerbate the risk by making rodent excrement more likely to become airborne. Although Virginia has reported only two human cases since 1993, the identification of infected rodents in the state highlights the need for vigilance in both eastern and western regions.
