True about Nipah virus are all except ?
**Core Concept**
Nipah virus (NiV) is a zoonotic virus belonging to the genus Henipavirus, which primarily infects bats and can be transmitted to humans through close contact with infected animals or contaminated food and secretions. NiV causes severe respiratory and encephalitic symptoms in humans, with a high mortality rate.
**Why the Correct Answer is Right**
The correct answer will be the statement that is true about Nipah virus. The virus is primarily transmitted through close contact with infected animals, such as bats, or contaminated food and secretions. NiV can also be transmitted through human-to-human contact in healthcare settings, particularly through contact with infected bodily fluids. The virus has a high mortality rate, ranging from 40% to 90% in different outbreaks.
**Why Each Wrong Option is Incorrect**
**Option A:**
Nipah virus is not primarily transmitted through vectors like mosquitoes or ticks, unlike many other zoonotic viruses.
**Option B:**
The correct answer will not be "Nipah virus is primarily transmitted through aerosolized particles." While the virus can be transmitted through close contact, aerosolized transmission is not a significant mode of transmission.
**Option C:**
Nipah virus does not have a distinct geographic distribution limited to a specific region, unlike some other zoonotic viruses.
**Option D:**
The correct answer will not be "Nipah virus is not associated with a high mortality rate." In fact, NiV has a high mortality rate, ranging from 40% to 90% in different outbreaks.
**Clinical Pearl / High-Yield Fact**
One key aspect of Nipah virus infection is the need for prompt recognition and isolation of infected patients to prevent human-to-human transmission. Healthcare workers should take precautions when handling patients with suspected NiV infection, including wearing personal protective equipment (PPE) and following strict infection control measures.
**Correct Answer: D. Nipah virus is not associated with a high mortality rate.**
