Part 1D: Check your understanding:

Use the above SIR Model Simulation to check your understanding

For the following questions, start with the following settings:
Population: 100
Initial Infected: 2
Transimission Rate: 1
Recovery Rate: 0.2


1) Using the suggested settings listed above, what is the number of infected people on Day 5?
4 12 20 76

2) Using the suggested settings listed above, what is the number of recovered people on Day 5
4 12 20 76

3) Using the suggested settings listed above, what is the total number of people who have been infected from the initial day to day 5?
12 20 32 45

4) What happens when you increase the Recovery Rate?
People leave the susceptible compartment more quickly.
The susceptible population instantly reaches zero.
People move into the recovered compartment more quickly.
People can move back into the susceptible compartment after being infected.

5) What happens when you increase the Transmission Rate?
The infection spreads faster, and the outbreak peaks earlier.
The infected curve becomes flatter
The infection never spreads
The recovered curve decreases more quickly.

6) Which rate can society influence?
Only the Recovery Rate, through better medical care.
Only the Transmission Rate, through policies such as social distancing and masks.
Neither—the rates are completely random.
Both can be influenced by intervention.


7) What would happen to a SIR model if people were given a medicine that reduced the number of days a person was sick?

The recovery rate would be smaller
The recovery rate would be larger
The transmission rate would be smaller
The transmission rate would be larger.

8) What would happen to a SIR model if masks were found to restrict the spread of the disease and all people in the population agreed to wear them?
The recovery rate would be smaller
The recovery rate would be larger
The transmission rate would be smaller
The transmission rate would be larger.

9) What would happen to a SIR model if people distanced themselves from others while they were sick?
The recovery rate would be smaller
The recovery rate would be larger
The transmission rate would be smaller
The transmission rate would be larger.
