Ebola Virus: Unraveling Its Mechanisms and Impact on the Immune System

The video explains why Ebola is dangerous, detailing how it attacks the immune system by targeting dendritic cells and other body cells, leading to severe symptoms and high mortality. Despite its severity, the video emphasizes that Ebola is less widespread than other diseases like flu and malaria. It concludes by highlighting the media's role in exaggerating Ebola's threat and encourages learning more about the immune system.

What is the primary genetic material found in a virus like Ebola?

• Carbohydrates

• DNA or RNA

• Proteins

• Lipids

Which cells are considered the 'brains' of the immune system that Ebola first attacks?

• Macrophages

• Dendritic cells

• Neutrophils

• B cells

How does Ebola manipulate dendritic cells to disrupt the immune response?

• By enhancing their protective mechanisms

• By reprogramming them to produce more viruses

• By causing them to produce antibodies

• By making them activate more antivirus cells

What happens when neutrophils are activated by Ebola?

• They effectively fight the virus

• They cause internal bleeding

• They produce antibodies

• They strengthen blood vessels

Which organ is severely affected by Ebola, leading to organ failure?

• Heart

• Lungs

• Liver

• Kidneys

What is a cytokine storm?

• A type of viral infection

• An overwhelming immune reaction

• A targeted attack on viruses

• A mild immune response

What paradoxical effect does a strong immune system have during an Ebola infection?

• It strengthens the virus

• It has no effect on the infection

• It causes more damage to the body

• It completely prevents the infection

How does Ebola primarily spread among humans?

• Through the air

• Through insect bites

• Through contact with bodily fluids

• Through contaminated water

Which disease kills more people annually compared to Ebola?

• Measles

• Common cold

• Malaria

• Chickenpox

What is the most infectious aspect of Ebola according to the video?

• The virus itself

• The media hype

• The symptoms

• The treatment
