Human Health
Only 0.5% of bats carry rabies. Although most bats do not have rabies, those that do may be clumsy, disoriented, and unable to fly, which makes them more likely to come into contact with humans. The highest occurrence of rabies in vampire bats occurs in the large populations found in South America. However, the risk of infection to the human population is less than to livestock exposed to bat bites.
The unique properties of the vampire bats' saliva have found some positive use in medicine. A study in the January 10, 2003, issue of Stroke: Journal of the American Heart Association tested a genetically engineered drug called desmoteplase, which uses the anticoagulant properties of the saliva of Desmodus rotundus, and was shown to increase blood flow in stroke patients.
