Ebola virus is a –
**Core Concept**
Ebola virus is a member of the Filoviridae family, which is a group of negative-sense single-stranded RNA viruses. This virus is known for causing severe and often deadly hemorrhagic fever in humans.
**Why the Correct Answer is Right**
The Ebola virus is a zoonotic pathogen, meaning it can be transmitted between animals and humans. It is primarily spread through direct contact with infected bodily fluids, such as blood, sweat, and saliva. The virus enters the host cell through a process called endocytosis, where it is engulfed by the cell membrane and then released into the cytoplasm. The viral genome is then replicated using the host cell's machinery, leading to the production of new viral particles.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because Ebola virus is not a member of the Paramyxoviridae family, which includes viruses such as measles and mumps.
**Option B:** This option is incorrect because Ebola virus is not a member of the Coronaviridae family, which includes viruses such as SARS-CoV-2.
**Option C:** This option is incorrect because Ebola virus is not a member of the Poxviridae family, which includes viruses such as smallpox.
**Clinical Pearl / High-Yield Fact**
It is essential to note that Ebola virus is highly contagious and can be spread through contact with infected bodily fluids, even in the absence of symptoms. Healthcare workers and individuals in close contact with infected patients are at high risk of transmission.
**Correct Answer: A. Filovirus**
