May infect as many as 50% of Wyoming moose
In 2008 a moose was discovered in the Star Valley that suffered from both Chronic Wasting Disease and a carotid artery worm, Elaeophora schneideri. It now turns out that up to 50% of the population may have the worm but the true extent of the effects are unknown. The worm is transmitted by the bite of a horsefly which tend to do well under hot and dry conditions.
