Malaria Transmission and Prevention Factors

Malaria, often seen as a tropical disease, historically affected many regions globally. Its decline in temperate areas is due to development, climate, and reduced mosquito breeding. However, in Africa, malaria remains a significant challenge due to the human-preference of local mosquitoes. Despite progress with bed nets, complete eradication in Africa is uncertain.

Where did the name 'malaria' originate from?

• Italy

• Africa

• Asia

• South America

What is one reason malaria was eradicated in temperate regions?

• Introduction of mosquito predators

• Draining of wetlands for agriculture

• Development of mosquito-resistant crops

• Increased use of vaccines

How does climate affect the development of the malaria parasite?

• Warmer climates slow down parasite development

• Cooler climates speed up parasite development

• The parasite cannot develop below 15 degrees Celsius

• The parasite thrives in dry climates

Why is malaria transmission higher in Africa compared to other regions?

• Mosquitoes in Africa are more aggressive

• African mosquitoes are resistant to insecticides

• The primary mosquito species in Africa prefers humans

• There are more swamps in Africa

What has contributed to the reduction of malaria deaths in Africa over the past 15 years?

• Increased use of bed nets

• Improved water sanitation

• Genetic modification of mosquitoes

• Development of a malaria vaccine
