The world is at war. Ebola is the enemy. Not Islamic State. Not Russia, Israel, Palestine, the United States, or any other nation or peoples you would like to insert here. No country—pardon the word choice—is immune to Ebola. The disease doesn’t care about cultural, political, racial, or religious differences that divide people. The disease indiscriminately attacks everyone.

Ebola should unite us—a global community rallying against a common enemy. But the disease can, already does, divide us. Fear, not infection, is Ebola’s great weapon of mass destruction. In parts of West Africa, farmers abandon crops for fear of infection; yesterday, I heard a BBC radio report claiming as many as 40 percent of farms in some countries. Fear. Fear of infection will divide us unless we unite first.
