Mono County Reports Third Fatality Due to Hantavirus
MONO COUNTY, Calif. (April 3, 2025) – Mono County Public Health has confirmed a third death due to Hantavirus in the Town of Mammoth Lakes. Hantavirus is a serious and often fatal illness which people can get through contact with infected deer mouse droppings, urine, or saliva. Deer mice are widespread in the Eastern Sierra region.
Hantavirus is endemic to Mono County and the surrounding region, commonly found in local deer mice. Human infection occurs through exposure to contaminated rodent droppings, urine, or saliva, typically when these materials become airborne and are inhaled. Person-to-person transmission does not occur.
