Charity vs. Capitalism in Africa

Jenifa John recently spent $1 on a billowy swath of gauze that could help keep her family alive. The 22-year-old mother of two in the village of Engutoto, Tanzania, bought a mosquito-repelling bed net that will keep parasite-bearing insects away from her young children while they sleep. It's a matter of utmost concern: Before she bought the net, one of John's children was hospitalized with malaria—and fortunately survived.

All across Africa, there's new hope in the long-running battle against malaria. In the last decade, funding to control the preventable, treatable disease has increased tenfold. And now, millions of insecticide-laced nets that keep mosquitoes away from sleeping men, women, and children are making their way into a growing number of homes, helping to defeat the spread of a disease that still kills up to 3 million people a year and 3,000 children a day. Experts say Africa could need upwards of 90 million bed nets to fight back against a disease that costs the continent an estimated $12 billion per year in lost economic potential.
