it's an open - but important - question as to whether there are differences in mortality associated with these different strains, which are already building up quickly.

giving people drugs that you know are going to increase the mutation rate even further is playing russian roulette - it's true the most mutations are not beneficial, but this is a numbers game, in the end. the more mutations you create, the more likely it is that you get one that works.

the threat of prescribing this drug and accidentally creating a superstrain out of it should not be underestimated.
