In this New York Times story, "Early HIV Therapy Sharply Curbs Transmission," I was brought up short by this wrenching, and morally execrable, paragraph:
"Although the evidence suggests that it would be good public health policy to lower infection rates by starting everyone on drugs as soon as they are infected, that is impossible in much of the world. For lack of money, clinics in Africa are turning away patients who are not just infected but close to death. And in some American states where money provided by the Ryan White Act has run out, poor uninsured people are on waiting lists."
It is certainly NOT impossible. It's possible to treat people who are infected worldwide, it's just not policy.
