Partners in Health has released an important new book, "Community-Based Treatment of HIV in Resource-Poor Settings". Reminiscent of the medical classic "Where There Is No Doctor", the book details with sophistication and clarity the treatment, management, data and communications issues for HIV patients in poor environments -- which is to say the overwhelming majority of those with HIV. The book speaks with the authority and pragmatism of the PIH professionals who have successfully confronted the HIV epidemic in Haiti and elsewhere.
