Almost 100 employees at Yosemite National Park were tested this week for the hantavirus.

The 96 employees volunteered to take the written survey and blood test. The tests were done Wednesday, and were conducted by the California Department of Public Health.

The hantavirus is a potentially deadly disease that is spread by exposure to infected mice or their droppings. There are nine confirmed cases of visitors to Yosemite National Park getting the hantavirus. All of them stayed in cabins in the same campground area. Three of those people died.

The CDPH wants to get a better understanding of how common or widespread the hantavirus may be. Sometimes infected people do not have symptoms, but it will still show up on a blood test.

The written survey includes questions to understand the employee’s work activities, exposure to mice and knowledge of the hantavirus.

The 96 employees were the first round who volunteered to be tested. Health officials will open up the test to other National Park Service employees soon.

The results of the tests are not known at this time.
