Today I’m going to talk about: Rabies

I’ve divided my presentation into two parts:

First I’d like to introduce about rabies and second I’ll present same.

So, let’s start with introduce

Rabies, acute, contagious infection of the central nervous system,

caused by a specific virus that enters the body through the bite of an

animal. All warm-blooded animals are susceptible, but in North America the

disease is most common in skunks, foxes, bats, raccoons, dogs, and cats.

Most of the cases of rabies in hhumans are caused by the bite of one of

these animals. The incubation period in humans varies from three weeks to

120 days, with an average of about four to six weeks. Rabies is virtually

always fatal when vaccine is not administered. Rabies is described in

medical writings dating from 300 bc, but the method of transmission or

contagion was not recognized until 1804. In 1884 the French bacteriologist

Louis Pasteur developed a preventive vaccine against rabies, and

modifications of Pasteur’s methods are still used in rabies therapy today.

The Pasteur program, or variations of it, has greatly reduced the

fatalities in humans from rabies. Modern treatment, following a bite by a

rabid or presumed rabid animal, consists of immediate and thorough

cleansing of the bite wound and injection into the wwound and elsewhere of

hyperimmune antirabies serum. A 14- to 30-day course of daily injections of

rabies vaccine is then given; booster doses are given 10 days after this

course and again 20 days later.

The traditional vaccine contains inactivated rabies virus grown in

duck eggs. A newer vaccine, which contains virus prepared from human cells

grown in the laboratory, is safer and requires a shorter course of

injections
