UCSF’s Charles Chiu, MD, PhD, discusses hantavirus, a potentially fatal virus transmitted by rodents such as deer mice, which is making news following an outbreak at a popular tourist area of Yosemite National Park. The recent cases are a reminder for campers to be cautious, but not necessarily fearful, said Chiu.
Previous hantavirus cases in Yosemite had originated at higher elevations, which are favored by the deer mouse that carries the virus, said Chiu, who directs the UCSF-Abbott Viral Diagnostics and Discovery Center. Other rodents, including house mice, are rarely if ever carriers of the virus.
