Unit Objectives
Main Assumptions in Model
• Currently, mosquitoes and humans do
not reproduce and/or die.
• Bed nets are 100% effective at
preventing malaria.
• Mosquitoes and people interact
homogeneously.
• Cured people cannot get sick again.
• No delay between mosquito acquiring
parasite and being infectious.

Graphical Analysis
• Set up the model so that the number of
sick people does not change.
• Set up the model so the number of sick
people increases over time.
• Set up the model so the number of sick
people increases then decreases over
time.

Challenge students
?
• What are some ways you can
raise money to help control
malaria in endemic areas?
What if you can only raise
enough to implement one
control measure? Use the
model to demonstrate which
control measure is the best
investment.
