I was diagnosed HIV-positive in 1990. I've been taking antiretrovirals for nearly eight years. I survived TB meningitis in 2002. I feel healthier now than I did 20 years ago.

But newspaper stories on XDR-TB (extensively drug-resistant TB) do not leave me quaking with fear of this new illness, writes Judy Seidman.
