  • They release more fluid causing internal bleeding
  • They become more effective against viruses
  • They activate liver cells

문제 6

선택형

  • Heart
  • Lungs
  • Liver
  • Kidneys

문제 7

선택형

What is a cytokine storm?

  • A strong antiviral drug

  • By consuming contaminated food
  • By contact with body fluids of symptomatic individuals
  • By insect bites

문제 9

선택형

How does the media influence public perception of Ebola?

  • 30%
  • 60%
  • 90%

문제 13

선택형

What role do macrophages play in the immune response to Ebola?

  • They destroy the virus directly
  • They signal blood vessels to release fluids
  • They activate dendritic cells
  • They create antibodies

문제 14

선택형

Why is the immune system unable to effectively respond to an Ebola infection?

  • It lacks the necessary cells
  • Ebola directly attacks and disables key immune cells
  • The virus hides in the brain
  • Ebola is resistant to all immune responses

문제 15

선택형

What happens to the body during a cytokine storm caused by Ebola?
