Alasdair Stuart responds to last Friday's piece about the cholera outbreak in Haiti:

Uh this may seem trivial, but cholera is BACTERIAL. Antibiotics work really well — you can actually see the critters (with a microscope). It's not a VIRUS (really tiny, laughs at antibiotics). Nice article otherwise.

Sara Dehm, who wrote the piece, responds:

It is indeed my factual mistake in the piece. Thanks to Alasdair for bring this to my attention — I won't make the error again!

There was one reference to cholera as a virus in the post, in the second paragraph. This has now been corrected.
