Community health workers like Isala Sesay are essential to fighting malaria in Sierra Leone, which killed an estimated 7,800 people in 2014 – twice the 3,956 who died of Ebola. “The community knows us and accepts us,” said Isala, who goes to far-flung villages to deliver basic healthcare. The government is developing a strategy to more effectively deploy and train the country's 15,000 community health workers.
