True about Rabies virus is –
## Core Concept
The Rabies virus is a type of lyssavirus that affects the central nervous system (CNS) of mammals, including humans. It is primarily transmitted through the saliva of infected animals, usually via a bite. The virus has a particular affinity for neural tissue.
## Why the Correct Answer is Right
The correct answer, although not directly provided, relates to characteristics of the Rabies virus. Typically, key points about Rabies include its classification as a lyssavirus, its transmission method, and its impact on the nervous system. Without the specific options, a general understanding is that Rabies virus is neurotropic, meaning it has an affinity for neural tissue, and its diagnosis and management are critical due to its almost invariably fatal outcome if not promptly treated.
## Why Each Wrong Option is Incorrect
Given the lack of specific options, let's hypothetically address potential incorrect statements about Rabies:
- **Option A:** If a statement claims Rabies is transmitted through respiratory droplets, it would be incorrect because, while rare, the primary mode of transmission is through bites.
- **Option B:** If an option suggests Rabies virus is a DNA virus, it would be incorrect because Rabies virus is actually an RNA virus, belonging to the Lyssavirus genus.
- **Option C:** Without specifics, any statement contradicting established facts about Rabies (like its incubation period, symptoms, or prevention methods) would be incorrect.
## Clinical Pearl / High-Yield Fact
A critical point to remember is that post-exposure prophylaxis (PEP) with Rabies immune globulin and the Rabies vaccine is highly effective in preventing the disease if administered promptly after exposure. Immediate washing of the wound with soap and water is also a crucial first step.
