Wiped out? Edit

I just watched Time's Arrow and I didn't see where it was said that cholera was wiped out- in fact Crusher said that cholera "isn't that virulent", present tense, which suggests it still exists in some form, even if it is not running rampant throughout Earth. I assume the line is an inference from the general statements made throughout Trek of disease being eliminated, but clearly since there are still doctors not all disease was wiped out, it is just easily cured and people don't suffer(I think). 31dot (talk) 19:29, September 22, 2012 (UTC)
