Noting advances in bednet, mosquito repellent and malaria vaccine technologies, Bill Gates, co-chair of the Bill & Melinda Gates Foundation, writes in a post on the foundation’s “Impatient Optimists” blog, “People used to say eradication was impossible, but we remain optimistic because human beings have a spectacular ability to innovate.” He concludes, “It is impossible to calculate the harm malaria has done to the world. But we have the ability to make generation after generation of better tools, and we can chart a course to end malaria” (10/19).
