We tend to think of innovation as something that happens at startups and dotcoms. But sometimes, the most powerful innovations happen at the end of a bumpy dirt road in rural Africa–in this case, a Senegalese village that has figured out how to virtually eradicate malaria.

As the father of a 7-year-old daughter, I was touched and inspired by the story of another dad I met during my recent trip to Senegal. I visited El Hadj Diop in his hometown of Thienaba, Senegal, where he told me the story of his own daughter, Ami.

At age 11, Ami was about to start her first day of school. But one week shy of that milestone, Ami contracted malaria. El Hadj didn’t think too much of it at the time. It began as a simple fever, and her family didn’t recognize the symptoms. On day three, her condition took a tragic turn. El Hadj was at work when he got the news that Ami had died. The malaria parasite had multiplied tens of thousands of times, attacking her brain and overwhelming her young body–all as the result of a tiny mosquito bite.

Malaria claims a life every 45 seconds. But El Hadj vowed that it would never kill again in his village. El Hadj took his message to his closest friends and neighbors. He worked with local women to form a group called Takku Liguey, which means “Working Together,” to help his village protect itself. Twice a day, women from the village perform what’s called set setal–they clean their surrounding areas, picking up trash and removing standing water, which are breeding grounds for malarial mosquitoes.

In addition, the group began giving new mothers and their babies mosquito nets. They taught mothers how to properly hang nets, and to tuck in all the corners so no malarial mosquitoes would bite them while they slept. (Mosquitoes that transmit malaria only come out at night, so it’s important that they use their nets from 9 p.m. to 5 a.m.)
