All are true regarding Hantavirus except:
**Core Concept**
Hantavirus is a zoonotic virus primarily transmitted through the bites of infected rodents, causing severe respiratory and renal complications in humans. The virus is known for its high mortality rate, especially in its hemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome (HPS) forms.
**Why the Correct Answer is Right**
Hantavirus primarily targets the endothelial cells of small blood vessels, leading to increased vascular permeability and subsequent fluid leakage into tissues. This results in the characteristic symptoms of HFRS, including fever, kidney failure, and hemorrhaging. The virus also causes apoptosis in infected cells, further exacerbating the disease.
**Why Each Wrong Option is Incorrect**
**Option A:** Hantavirus can be transmitted through aerosolized virus particles, but this is not the primary mode of transmission. Aerosol transmission is more relevant to other viruses like SARS-CoV-2.
**Option B:** Hantavirus primarily affects rodents, not humans, although humans can become infected through contact with infected rodents or their droppings.
**Option C:** Hantavirus is not a type of influenza virus; it belongs to the Bunyaviridae family.
**Clinical Pearl / High-Yield Fact**
It's essential to remember that hantavirus infection can be prevented by wearing protective clothing and masks when handling rodents or their droppings, and by avoiding contact with wild animals.
**Correct Answer: C. Hantavirus is not a type of influenza virus; it belongs to the Bunyaviridae family.**
