TED-Ed: What we know (and don't know) about Ebola - Alex Gendler

The transcript discusses the Ebola virus, which was first identified during an outbreak in central Africa. It describes the virus's symptoms, which start like the flu but quickly worsen, leading to severe hemorrhagic fever. The virus attacks the immune system, causing a cytokine storm that results in internal and external bleeding. Ebola is transmitted through bodily fluids, making it less contagious than airborne viruses. Despite its severity, outbreaks are sporadic, and the virus is difficult to study due to its rarity and the poor infrastructure in affected regions. Efforts to contain outbreaks focus on isolation, sanitation, and information, with ongoing research into vaccines and treatments.

What is the initial symptom of Ebola that resembles a common illness?

• Blurred vision

• High temperature

• Severe headache

• Loss of taste

How does the Ebola virus primarily spread between individuals?

• Via contaminated water

• Through airborne particles

• By insect bites

What is a cytokine storm in the context of Ebola?

• A method of virus transmission

• An immune system overload damaging blood vessels

• A treatment for Ebola

• A type of fever caused by the virus

Why is Ebola less contagious compared to other viruses?

• It can only be contracted through food

• It is transmitted by mosquitoes

• It spreads through the air

• It requires direct contact with bodily fluids

What are the main strategies to control an Ebola outbreak?

• Isolation, sanitation, and information

• Genetic modification of the virus
