Ebola Outbreak and Virus Evolution Quiz

What was the initial reaction to the rumors of a mysterious disease in Guinea?

• It was dismissed as a minor outbreak.

• It was thought to be a common flu.

• There was concern about evolutionary changes in the virus.

• It was immediately identified as Ebola.

How does Ebola primarily spread among humans?

• Through contaminated water.

• Through airborne particles.

• Through mosquito bites.

• Through direct contact with infected body fluids.

What is the significance of a virus's genome in its intervention and prevention?

• It has no significant role.

• It makes the virus immune to vaccines.

• It acts as a blueprint for the virus.

• It determines the color of the virus.

What role does natural selection play in virus evolution?

• It prevents viruses from mutating.

• It helps viruses spread more quickly if mutations are beneficial.

• It stops viruses from infecting humans.

• It makes viruses less harmful.

What was a major challenge for Sierra Leone during the Ebola outbreak?

• A strong healthcare system.

• Destruction of health clinics due to civil wars.

• Lack of roads.

• Overpopulation.

Why did the Ebola outbreak create a 'Perfect Storm' in West Africa?

• Because the virus was airborne.

• Due to the region's low population density.

• Due to the combination of a weak health system and a mobile population.

• Because of the region's excellent healthcare facilities.

What was a significant consequence of the Ebola outbreak for healthcare workers?

• They were immune to the virus.

• They faced a 20-fold increased risk of infection.

• They were unaffected by the outbreak.

• They were the primary carriers of the virus.

What was the impact of a mutation in the Ebola virus during the outbreak?

• It made the virus visible to the naked eye.

• It stopped the virus from spreading.

• It increased the virus's infectivity in humans and primates.

• It made the virus less infectious.

Why is the world not prepared for a long and sustained disease pandemic?

• Because of uniform health quality worldwide.

• Due to disparities in health systems across countries.

• Due to the abundance of vaccines.

• Because pandemics are rare.

What is essential for controlling viruses and responding to outbreaks?

• Understanding virus biology and having a rapid response.

• Ignoring minor outbreaks.

• Relying solely on vaccines.

• Completely eradicating all viruses.
