KQ1 Disease Diffusion

In which season do vector-borne diseases often reach their peak in tropical locations?

• Summer

• Spring

• Winter

• Rainy season

Which type of diseases can be spread by vectors such as viruses, bacteria, and parasites, from animals to humans?

• Non-communicable diseases

• Genetic diseases

• Zoonotic diseases

• Communicable diseases

Which is the odd one out?

• Physical barriers

• Neighbourhood effect

• Economic development

• S shaped curve

Answer explanation

Three of these are linked to the Hagerstrand Diffusion Model:

Neighbourhood effect

S shaped curve

Physical Barriers

Diseases that are commonly found in a certain area, demographic and time period are called...

• pandemic

• epidemic

• endemic

• communicable

Which is the odd disease out?

• Type 2 Diabetes

• Covid-19

• Cardiovascular disease

• Cancer

Which natural hazard encouraged the spread of cholera in Haiti?

• 
• 
• 
• 

What method of diffusion is most appropriate in describing how cholera got to Haiti?

• Hierarchical

• Contagious

• Infectious

• Relocation

Which of these is not a seasonal disease?

• Malaria

• Covid-19

• Common cold

• Dengue fever

Climate change will have what effect on the future pattern of malaria prevalence

• As the whole world warms, malaria incidence will rise everywhere

• Malaria will rise in Europe as it gets warmer but decrease on the equator as rain decreases

• Patterns will stay the exact same

• Malaria will decrease globally as there will be higher temps but little rainfall

Why does a lack of water increase disease risk?

• Less water = lower sanitation = water borne diseases

• Less water = more people sharing one source = poorer quality

• People turn to dirtier sources which are more likely to have pathogens

• People share with animals = zoonotic diseases may spreaed
