The activity is irrelivant in the thought process:

Activity generates X dollars per participant
There is a Y% chance that Z people at the activity will engage in an
act that incurs $J amount of costs.

This is the identical problem being discussed with Ethanol production
in figuring out how much fossil fuel is offset by ethanol production
and use.

Ethanol being the money, Fossil fuel use in production of ethanol
being the infection.

Does the generation of ethanol in fact offset the use of fossil fuels
when fossil fuels are used in the production of ethanol.

Can the amount of money generated in a walk offset the the costs
incurred by the walk (in the OP'er mindset, assuming an incurring of

The same mathmatical problem can be distilled to the quote:

"Is the cure worse then the disease."

Or the most simple concept of "ROI" base on the various inputs.

At what point, given the circumstances, does the activity return a
profit (positive return).

For the original post there are various points that need to be
addressed to get anywhere:

% of people infected
% that are single
% that are looking for sex
% base chance of infection
regessors that may impact infection
age groupings of the samples
$ cost per year of infection ($ in the first yearm $ in second year)
$ generated per person in a walk

Given 10000 people raising $100 each with a 15% singles rate and 50%
of that 15% actually looking for sex with a 60% chance of infection.
We then apply a 40% infection rate to the participants.

Group the population of the 1000 into the 18-35,36-55,and 55+ groups
then find your costs and work with the assumption that everyone lives
to 75 years of age for the sake of costs. The longer you live with a
dieases, the more cost you incur.

Potential regressors could be excericse, ethnic background, annual
income, history of heart diease, etc.

Based on the OP I can only come to one conclusion based on the data,
model chosen, and topic at hand:

The original post wasn't funny and based on the data and potential
model the only sound conclusion is: Walks are to raise funds for
researching cures and treatments, not paying for treatments.
