Why is it so expensive to save lives?

Abstract

Nets to prevent malaria are estimated to cost about $4.50 each. When $4,500 is donated, 1,001 nets can be purchased and distributed, resulting in 795 nets being used. These nets protect 1,431 people, out of which it is estimated 12 would have died every year of any cause. Evidence indicates insecticide-treated nets reduce deaths from 12 to 11.4/year, resulting in 1.3 potential lives saved. However, accounting for funding from other sources, the donation likely saves one life. Additional benefits include averting non-fatal malaria infections and economic effects like increased earning potential for children who avoid malaria. – AI-generated abstract.
