Virus outbreak in a model city: How important is social distancing?

The video explores a simulation of virus spread in a model society using marbles. It examines scenarios with no measures, testing and quarantining, and social distancing. The results show that without measures, infections grow exponentially, but testing and quarantining reduce the peak infection rate. Adding social distancing further decreases infections. The video concludes that social distancing is crucial in managing virus spread, especially considering healthcare capacity limitations.

What color do marbles turn when they become immune?

• Blue

• Green

• Yellow

• Red

In the first simulation, what happens to the infection rate over time?

• It remains constant.

• It decreases steadily.

• It decreases and then increases again.

• It grows exponentially and then stabilizes.

What is the maximum percentage of infected marbles in the first simulation?

• 90%

• 75%

• 60%

• 50%

How does the testing and quarantining policy affect the infection rate in the second simulation?

• It reduces the maximum infection rate to 30%.

• It stops the infection completely.

• It increases the infection rate.

• It has no effect.

What additional measure is introduced in the third simulation?

• Increased testing

• Social distancing

• Vaccination

• Travel restrictions

What percentage of marbles work from home in the third simulation?

• 25%

• 100%

• 50%

• 75%

Why is social distancing important according to the simulation?

• It makes marbles immune faster.

• It has no impact on virus spread.

• It increases social interactions.

• It helps reduce the strain on healthcare systems.
