IB Geo: F2.4 Cholera and Malaria

What is the primary transmission mechanism for cholera?

• Airborne droplets

• Direct contact with an infected person

• Contaminated water and food

• Mosquito bite

Which environmental factor is crucial for malaria transmission?

• Access to clean water

• Proximity to breeding sites like stagnant water

• Inadequate sanitation facilities

• War or natural disasters

What is the vector for malaria transmission?

• Chitin-containing shells of shellfish

• Contaminated water and food

• Brackish and marine waters

• Anopheles mosquito

In which regions is malaria transmission more intense and year-round?

• Areas with poor water and sanitation infrastructure

• Warmer regions closer to the equator

• Cooler or drier regions

• Higher elevations

What is the role of altitude in malaria transmission?

• It has no impact on transmission

• It increases transmission intensity

• It decreases transmission intensity

• It causes seasonal transmission

Where are cholera outbreaks often linked to?

• Specific events that disrupt water and sanitation systems

• Warmer regions closer to the equator

• Areas with poor water and sanitation infrastructure

• Proximity to breeding sites like stagnant water

What is the focus of strategies for controlling cholera?

• Oral cholera vaccines

• Use of insecticide-treated bed nets

• Indoor residual spraying

• Improving water, sanitation, and hygiene practices

What is the most essential for developing targeted interventions to reduce the burden of cholera and malaria?

• Understanding the differences in their transmission mechanisms

• Increasing funding for medical research

• Understanding the similarities between the two diseases

• Focusing on improving healthcare infrastructure

What is the role of environmental factors in the transmission of cholera and malaria?

• Both diseases are influenced by climatic conditions

• Cholera is influenced by poor water and sanitation infrastructure while malaria is influenced by climatic conditions
