The first loss of life was reported earlier this full month. Monday that the 4 visitors might have been exposed even though vacationing at Curry Village Yosemite officials said. They warned those who stayed in the village’s tent cabins from mid-June through the end of August to avoid any symptoms of hantavirus, that may include fever, aches, chills and dizziness. Of the 587 documented U.S. Cases since the virus was identified in 1993, about one-third proved fatal. There is no specific treatment for the virus. Federal health officials state symptoms might develop up to five weeks after exposure to urine, droppings, or saliva of contaminated rodents, and Yosemite advised people to watch for symptoms for up to six weeks. Officials said thousands of people visit the park every complete month, so it will be impossible to track everyone who had place feet in Curry Village.Two additional infants with HCS underwent transfusion at 4 and 11 a few months, respectively.
