Testing a fixed amount of randomly selected individuals

fdabl opened this issue · comments

Hi there,

First, let me say that I came across this package back in April and was already very impressed, but what you have done since is truly amazing. Thank you!

I am trying to familiarize myself with all the updates, so apologies if there is a straightforward answer to my question. In particular, I am interested in assessing how testing a fixed amount of randomly selected people in addition to the testing that symptomatic individuals have access to can influence an epidemic.

Currently, it seems one can allocate 'PCT_TESTED_PER_DAY' % of tests, of which a maximum of 'MAX_PCT_TESTS_FOR_SYMPTOMATICS' % is available to symptomatic individuals. If the amount of tests is not exhausted, then the remaining tests go to traced contacts, and finally to the random sample. However, this does not allow me to specify that X% of the population is randomly sampled and tested periodically. Is there a way to do this?

I suppose I could tweak 'TESTING_COMPLIANCE_RATE_RANDOM' to get an approximation of the fixed percentage, but that will always be stochastic since I can't control how many tests actually go to symptomatic individuals.

Thank you for any input!

Hi @ryansmcgee, I know that you are probably very busy, but is there any chance you could help me out here? Thanks!
