**Question:** About rabies, the following statements are true:

A. Rabies is a viral infection caused by the Lyssavirus family.
B. Rabies primarily affects mammals, with dogs being the most common reservoir.
C. Rabies is transmitted through the saliva of infected animals, typically bites.
D. Rabies has high mortality rate once symptoms appear.

**Core Concept:**
Rabies is a viral infection caused by the Lyssavirus family, which belongs to the family Rhabdoviridae. Lyssavirus is a genus of negative-sense, single-stranded RNA viruses that infect mammals, primarily affecting the central nervous system. The virus is commonly transmitted through the saliva of infected animals, particularly dogs, which serve as the primary reservoir.

**Why the Correct Answer is Right:**
A. Statement A is correct as rabies is caused by a viral infection belonging to the Lyssavirus family.
B. Statement B is correct because dogs are the most common reservoir for the virus, contributing to a significant portion of human rabies cases.
C. Statement C is correct as rabies is primarily transmitted through the saliva of infected animals, usually through bites.
D. Statement D is correct as rabies has a high mortality rate due to the rapid progression of the disease and lack of effective antiviral therapy once symptoms appear.

**Why Each Wrong Option is Incorrect:**
A. Statement A is not entirely correct, as the Lyssavirus family includes not just rabies virus but also other viruses like Lagos bat virus, Rabies-like virus, and the Eurasian bat virus.
B. Statement B is not entirely correct because although dogs are common reservoirs, other mammals like raccoons, skunks, and foxes can also transmit the virus to humans.
C. Statement C is incorrect because, in addition to bites, rabies can also be transmitted through mucous membranes, abrasions, or even through the placenta in pregnant women.
D. Statement D is incorrect because timely post-exposure prophylaxis (PEP) with a series of vaccinations and immune globulin administration can significantly reduce the risk of developing rabies.

**Clinical Pearl:**
In the context of rabies prevention, it is essential to understand that the virus can be transmitted through multiple routes and not only via bites. Immediate and comprehensive post-exposure prophylaxis is crucial for reducing the risk of development of rabies. Prompt vaccination and immune globulin administration, if available, should be initiated within 72 hours of potential exposure for optimal efficacy.
