Deadly infection at national park leaves two dead

Thousands of visitors to Yosemite National Park, one of America’s top tourist attractions, have been warned to watch out for symptoms of a rare rodent-borne disease which has already killed two people.

Another case hantavirus has been confirmed, and a fourth is being investigated. The first death was reported earlier this month.

Yosemite said the visitors might have been exposed at the park’s Curry Village and should beware of any symptoms of hantavirus, which can include fever, aches, dizziness and chills.

Symptoms may develop up to five weeks after exposure and Yosemite advised visitors to watch for symptoms for up to six weeks.
