For decades, AIDS has taken the lives of millions of people and infected millions more worldwide. The key to reducing the effect of AIDS, and even potentially curing it, involves treating patients as early as possible after being diagnosed with HIV, before the disease damages organs. San Francisco General Hospital developed the RAPID program for this purpose, with the goal of “Getting to Zero” the number of new infections and deaths.

In the developing world, intestinal worms stunt physical and mental growth, drain energy, and can inhibit school work for children. Deworm the World is a global campaign that lobbied the Delhi government to regularly distribute deworming pills to school children.

Two columns on how Iran is treating its massive epidemic of injecting drug use by tackling it as a health problem, effectively lowering H.I.V. rates among drug users using an approach to drugs known as harm reduction.
