September 28 is chosen as World Rabies Day because it marks the anniversary of the death of Louis Pasteur, the French chemist and microbiologist who developed the very first effective rabies vaccine.
How Rabies is Transmitted
Rabies is a vaccine-preventable, zoonotic viral disease that targets the central nervous system. Because the rabies lyssavirus is highly concentrated in the salivary glands of an infected host, transmission primarily relies on fluid-to-tissue contact.
Animal Bites: This is the most common route. In up to 99% of human cases globally, domestic and stray dogs are responsible for transmitting the virus via a bite. In parts of the world like North America, wildlife such as bats, raccoons, skunks, and foxes are the primary transmitters.
Scratches and Open Wounds: Transmission can happen if an infected animal scratches a person, breaking the skin, or if its infected saliva comes into contact with an existing, open wound.
Mucous Membranes: The virus can be transmitted if infected saliva makes direct contact with a person’s wet membranes, such as the eyes, nose, or mouth (for example, if an infected animal licks a person's face)
