Question

In the simulation you did, the disease was transmitted every time an infected person met an uninfected person who was not immune. In the real world, these people may not have become sick. Why not? State as many reasons as you can.

Answer 1

Sample Response:

Germs are living things and may not survive the transaction.

Just because people meet does not mean that they will make contact.

An uninfected person may be able to fight off the infection before getting sick and passing it on to others.

Answer 2

Answers:

- A person may be immune to the disease and thus he/she can't transmit the infection to others

- Persons don't only need to meet each other but they have to be in contact to spread the infection

- Certain persons may exhibit specific transmission rates for different infections
