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.

Famous quotes containing the words human and/or health:
“If you complain of people being shot down in the streets, of the absence of communication or social responsibility, of the rise of everyday violence which people have become accustomed to, and the dehumanization of feelings, then the ultimate development on an organized social level is the concentration camp.... The concentration camp is the final expression of human separateness and its ultimate consequence. It is organized abandonment.”
—Arthur Miller (b. 1915)
“At last I feel the equal of my parents. Knowing you are going to have a child is like extending yourself in the world, setting up a tent and saying “Here I am, I am important.” Now that I’m going to have a child it’s like the balance is even. My hand is as rich as theirs, maybe for the first time. I am no longer just a child.”
—Anonymous Father. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 5 (1978)
