Rabies is a virus that may affect the brain and spinal cord of all mammals, including dogs, cats and humans. Though preventable, there is good reason that the word “rabies” evokes fear in people. The disease has been reported in every state except Hawaii, and everywhere throughout the world except for Australia and Antarctica. Annually, rabies causes the deaths of more than 50,000 humans and millions of animals worldwide. Once symptoms appear, the disease results in fatality.
