## **Core Concept**
Rabies is a viral infection caused by the rabies virus, which primarily affects the nervous system of mammals, including humans. It is typically transmitted through the saliva of infected animals, often via bites. Understanding the modes of transmission, the role of post-exposure prophylaxis (PEP), and the characteristics of the infection in humans is crucial.

## **Why the Correct Answer is Right**
The statement that "Suturing is usually recommended on local wound" is generally false in the context of rabies post-exposure management. Immediate suturing of the wound is not recommended as part of the initial management. Instead, the wound should be thoroughly cleaned and flushed with soap and water, and then an antiseptic solution is applied. Suturing may be considered after the administration of rabies immunoglobulin and initiation of the rabies vaccination series, usually 24 to 48 hours later, depending on the clinical judgment.

## **Why Each Wrong Option is Incorrect**
- **Option A:** "Rabies is dead end infection in man" is true. Humans are considered a dead-end host for the rabies virus because the virus does not spread from person to person; humans do not contribute to the virus's lifecycle in nature.
- **Option B:** "Can be transmitted by aerosols" is true. Besides bites, rabies can also be transmitted through aerosols (inhalation) of the virus, which can occur in caves with infected bats or in laboratory settings.
- **Option D:** "Human bite can transmit Rabies infection" is generally considered false in the traditional sense. Rabies transmission to humans usually occurs through animal bites. Human-to-human transmission of rabies through bites is extremely rare and has been documented in very few cases, mostly through organ transplantation from rabies-infected donors or, theoretically, through deep bites that inoculate the virus directly into tissues.

## **Clinical Pearl / High-Yield Fact**
A critical clinical pearl is that post-exposure prophylaxis (PEP) for rabies, which includes immediate washing of the wound, administration of rabies immunoglobulin, and a series of rabies vaccinations, is highly effective in preventing the disease if administered promptly after exposure.

## **Correct Answer: B.**
