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.

“Martha: “What is Autumn?” Jan: “A second spring, where the leaves imitate the flowers. Maybe it would be so too with human beings that you would see bloom if only you helped them with your patience.””
—Albert Camus (1913–1960)
“Some fear that if parents start listening to their own wants and needs they will neglect their children. It is our belief that children are in fact far less likely to be neglected when their parents’ needs—for support, for friendship, for decent work, for health care, for learning, for play, for time alone—are being met.”
—Wendy Coppedge Sanford. Ourselves and Our Children, by Boston Women’s Health Book Collective, introduction (1978)
