Description Stefan Edlund CLA 2010-11-03 16:32:01 EDT 
As suggested by Tracy at Lockheed. For simple disease models such as SI, SIR, SEIR models it's easily calculated as beta/recover rate.

Other disease models we need to handle on a case-by-case basis.

Actually showing Ro in the disease wizard is actually likely to cause more questions than it answers.
if the fraction of the population that is susceptible, s==1.

In general R<sub>o</sub>~s&beta;/(&gamma; + &mu;)
This is actually problematic to show in the wizard as we do not have 's'. We can try to get it from the innoculators/infectors but users will likely create the disease before creating them. This would create more questions than it answers.

Instead, I updated the context sensitive help on the Disease Wizard explaining the difference between &beta. and R<sub>o</sub>. To see the new help, get latest and create a new disease. Click the question mark then select the link to Disease Wizard Help.
