Disease vectors, toxic waters ... With all this around you'd think the scare mongers could show lots of sick people. Alas, the claims are empty and those folks aren't as dumb and incompetent as they're made out to be.
And, have you noticed any of the rescuers wearing protective gear? Any hazmat suits? I haven't. They just splash through the water (if they're in the flooded areas) and do their work.
