How Ebola kills

The video explains how a virus with only seven genes can cause severe infections by overwhelming the body's defenses. It spreads through direct contact with bodily fluids and penetrates mucous membranes. The virus targets immune cells, turning them into virus-producing machines, and disrupts the immune response by causing an uncontrolled release of cytokines. This leads to inflammation, blood clotting, and weakened blood vessels, ultimately resulting in organ failure and death.

How does the virus primarily spread from one person to another?

• Through the air

• Direct contact with bodily fluids

• Insect bites

• Contaminated food

What role do macrophages play in the virus's attack on the immune system?

• They prevent cytokine release

• They destroy the virus

• They alert other immune cells

• They become virus-producing machines

What happens when cytokine production becomes uncontrollable?

• The immune response is enhanced

• The body becomes more resistant to the virus

• The inflammation response goes haywire

• The virus is neutralized

What is the consequence of blood clots forming in small blood vessels?

• Improved immune response

• Strengthening of blood vessels

• Deprivation of oxygen to organs

• Increased blood flow to organs

What ultimately leads to the death of the infected person?

• The virus leaving the body

• The immune system fully recovering

• The virus becoming inactive

• Multiple organ failure
