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.

Famous quotes containing the words human and/or health:
“Catholics think of grace as a supernatural power which God dispenses, primarily through the Church and its sacraments, to purify the souls of naturally sinful human beings, and render them capable of holiness.... Protestants think of grace as an attribute of God rather than a gift from God. It is a shorthand term signifying God’s determination to love, forgive, and save His human children, however little they deserve it.”
—Louis Cassels, U.S. religious columnist. “The Catholic-Protestant Differences,” What’s the Difference?, Doubleday (1965)
“The years when we are parenting teenagers are the high point, the crest when everything seems to be in bright colors and in ten-foot letters.”
—Jean Jacobs Speizer. Ourselves and Our Children, by Boston Women’s Health Collective, ch. 4 (1978)
