The only way testing is really going to work is for an entire area, then you reduce the circulation between those positive and those not.    That would alot of test to do a million people and then organise it all, the only real alternative is distancing and then treatment for those who become obvious in their symptoms.   Since the ill wont have spread before receiving treatment that is why the spread factor goes down and control increases, at present people wont accept this is a virus which can appear as nothing spread and then kill.
   The two extremes are confusing people and making some believe its non existent just before they die, we've not had this unique mix before and is especially effective at spreading in society that wont accept medical research or government statistics.   It is a perfect storm unfortunately, theres no excuse to open a casino with that background ongoing except money is more valuable then reducing the mix of people and this natural spread behaviour.
