How scary is rabies?

Rabies is a terrifying disease. Once the virus enters a human host — typically by way of a bite from an infected animal — it creeps along from nerve cell to nerve cell until it reaches the brain. It usually takes a month or more for symptoms to show.

Someone with rabies can produce a lot of saliva (spit), and muscle spasms in their throat might make it hard to swallow. This causes the "foaming at the mouth" effect that has long been associated with rabies infection.

Why does rabies make animals violent?

A new study shows how a small piece of the rabies virus can bind to and inhibit certain receptors in the brain that play a crucial role in regulating the behavior of mammals. This interferes with communication in the brain and induces frenzied behaviors that favor the transmission of the virus.

Can rabies occur after 20 years?

We report an unusual case of rabies, with very prolonged incubation period suspected to be more than 20 years, from the South Western state of India, Goa.
