YOSEMITE NATIONAL PARK -- The threat of worldwide outbreak of a virus has caused health officials to issue an alert at Yosemite National Park.

Yosemite park rangers are warning every visitor about the outbreak of the hanta virus. The virus is spread by rodents.

Eight people are already known to have contracted the disease.

And three people have died in California, Pennsylvania and West Virginia. There maybe even more cases, including as far away as France.

The worst part? There is no known treatment or cure.

Early symptoms include fatigue, fever and chills can take up to six weeks to appear. Those quickly give away to coughing and breathing problems as the lungs fill with fluid.
