Hantavirus is an infection caused by inhaling rat feces contaminated with the virus. This virus had been found a The Grand Canyon before and recently reaappeared at Yosemite Park recently, with two cases reported among people staying at their Tent Cabins.
Although there are no current reported cases in Arizona, this is a good reminder to maintain excellent ventilation when cleaning outside areas that are dusty and which may contain rat droppings.
