When the United States Marine Corps went ashore in Liberia in August, it discovered an enemy that had no ties to the various factions in the civil war there. More than 50 of the 225 service members, roughly a quarter, who landed in Liberia last month were hospitalized because of a longtime scourge of mankind: malaria.
That's an amazing attack rate. Some of those marines may suffer from malaria for the rest of their lives. Liberia has been far more dangerous, on a percentage basis, than Iraq.
