The Ebola epidemic has killed 3,431 people in Guinea, Sierra Leone and Liberia; it has killed one in the United States. Liberia's Defense Minister Brownie Samukai told the U.N. Security Council in September that the disease poses a "serious threat" to the country's existence; the Obama administration recently reminded everybody that "[America's] structure would preclude an outbreak." Health care workers are threatening to strike over dissatisfaction with wages; the U.S. sent 3,000 military personnel directly into the area to help combat the epidemic.
