Rabies, like many diseases, is dependent on local ecosystem conditions. When we have wildlife outbreaks in the U.S., they seed likely feeding areas of foxes and raccoons with a baited oral vaccine.

India has an extraordinarily complex and destructive combination of lifestyle, livelihood, religion, and economy. A big likely contributor to rabies surging there in recent decades is a specific medication given to cattle.
