Transmission Model

Use the model below to explore transmission type.

Questions

Please answer the questions below.

Turn vector-infection and indirect-infection to "Off." Change "transmission type" to touch. You may need to slow down the time using the slider at the top.

What happens to the population during this transmission type? Who is getting infected? 

Using the same set up in question 1.

How long until the majority of the population is infected?

 

Turn vector-infection and indirect-infection to "Off." Change "transmission type" to airborne. You may need to slow down the time using the slider at the top.

What happens to the population during this transmission type? Who is getting infected? 

Using the same parameters in question 2. 

How long until the majority of the population has been infected?

Turn off the transmission type, so organisms are no longer transmitting the disease to each other. Turn on "vector-infection." A vector is something that carries the infection, like how mosquitos can carry malaria and other diseases. 

For the vector organism, yellow is uninfected, blue is carrier for infection.

What do you notice happen to the population of vector insects over time?

 

Turn off "vector-infection," leave "transmission-type" set for "none" and turn on "indirect-infection."

What do you notice about this type of transmission, compared to the others you looked at?
