What virus is responsible for rabies in animals?

Rhabdovirus is the virus that causes rabies, affecting both animals and potentially humans.

What are the symptoms of Foot and Mouth Disease (FMD) in livestock?

FMD causes sores in the mouth and on the feet of livestock, primarily affecting animals like cattle and goats.

What is the significance of the Human Immunodeficiency Virus (HIV)?

HIV attacks the immune system, leading to Acquired Immunodeficiency Syndrome (AIDS), which compromises the body's ability to fight infections.

How does the Citrus Leprosis Virus affect citrus plants?

The Citrus Leprosis Virus causes blemishes on leaves and fruit, degrading the quality of the harvest.

Which virus causes Polio and how is it transmitted?

The Picornavirus causes Polio, and it is typically transmitted through feces from an infected individual.

What are some symptoms of the influenza virus as mentioned in the transcript?

Symptoms of the influenza virus include fever, cough, sore throat, and body aches.

What role do insects play in the transmission of plant viruses?

Insects, such as aphids or leafhoppers, often serve as vectors, transmitting viruses from one plant to another.

What is Ebola virus, and what are its implications for human health?

The Ebola virus attacks the immune system and can lead to severe illness or death, often spread through bodily fluids of infected individuals.
