Rabies

Rabies

Rabies is an acute zoonotic viral disease, transmitted through contact (mainly bites and scratches) with infected animals, both domestic and wild. Rabies is invariably fatal in the absence of adequate post-exposure prophylaxis.

Symptoms

Paresis or paralysis, delirium and convulsions.

Infectious Agents

The infectious agent is Rabies virus, a rhabdovirus of the genus Lyssavirus.

Mode of transmission

Rabies is usually transmitted by the bite of an infected mammalian species (e.g. dog, cat, fox or bat). The bites or scratches introduce virus-laden saliva into the human body.

No human-to-human transmission of rabies has been documented

Prevention

The most cost-effective strategy for preventing rabies in people is by eliminating rabies in dogs through animal vaccinations
