I don't disagree with you, actually. Like I said, if you are in a high risk group, the math changes - but I agree that mass preventive chloroquine adminstration would not be a good idea. However, if there is a large outbreak, shortages of chloroquine or you have to wait days/weeks for your doctor to prescribe chloroquine - that is not a place i personally want to be.

On another note, this is a nice thread helping me (and maybe others) inform them about side effects and efficacy of possible treatments.
