An example of an epidemic model with a population slider, asymptomatic population slider, microencephaly birth rate slider, and graph. There is a 75% transmission rate, and a "reduced risk factor percentage" due to awareness, education, and action built into the code, but no sliders to manipulate those variables.
(Statistics bear out a population saturation rate of 75% with a substantial reduction, but not elimination, of risks associated with giving birth to a child with microencephaly once becoming aware of the infection.)
