Understanding African Sleeping Sickness

The video discusses a deadly parasite transmitted by the tsetse fly in Africa, which causes African sleeping sickness. It follows Dwight's experience, who was bitten by an infected fly, leading to severe symptoms. The parasite evades the immune system by changing its protein coat, making it difficult to treat. Without timely medication, the disease can be fatal.

Why is it critical to get medicine quickly after being infected?

• To reduce the cost of treatment

• To ensure the parasite does not become resistant

• To avoid severe symptoms and potential death

• To prevent the spread of the disease to others

How many times had Dwight been to Africa before his illness?

• 5 times

• 15 times

• 8 times

• 11 times

What was the initial symptom that Dwight experienced?

• Extreme weakness

• Severe headache

• Skin rash

• High fever

What is the size comparison of the tsetse fly?

• Same size as a house fly

What makes the tsetse fly particularly troublesome?

• Its bright color

What is the name of the parasite that causes African sleeping sickness?

• Trypanosoma

• Giardia

• Leishmania

• Plasmodium

How do the parasites move through the bloodstream?

• Using cilia

• Using flagella

• Using pseudopodia

• Using fins

What is the primary defense mechanism of the trypanosomes against the immune system?

• Hiding inside red blood cells

• Releasing toxins

• Forming cysts

• Changing their protein coat

What happens to the patient's body when the red blood cells are devastated?

• The patient becomes paralyzed

• The patient goes into a coma

• The patient develops a high fever

• The patient experiences severe pain

What is the ultimate consequence if the disease is left untreated?
