The Safe and Smart Savings program at Zelyn Academy creates a “safe space," where girls can talk about two seemingly disparate — and often taboo — topics: smart savings and reproductive and sexual health, and help break the cycles of poverty and HIV/AIDS.

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.

Among the challenges for HIV-positive inmates are lack of food that meets their dietary needs and susceptibility to tuberculosis.

Up until 2015, people living with HIV in the U.S. could not buy term life insurance, outside of a few small-value employer policies. Æqualis, a new company in partnership with Prudential Financial, began offering 10- and 15-year life insurance policies to individual consumers to help them and to reduce stigmas surrounding the disease.

Three African countries are successfully reducing the transmission of HIV through treatment and education, surpassing many developed countries in reducing cases. Although each is unique, the key lessons include using comprehensive, community-based approaches and strategies that involve collective action.
