Oliver had never left the United States when the Mormon church sent him on a mission in Chile in 2002. Eager to serve, the 19-year-old dove into missionary work. But after a few weeks, he began to experience crippling stomach pain. At first, Oliver was embarrassed by his ailment and tried to conceal it. After he lost 30 pounds, he approached the mission president’s wife—who was responsible for granting access to medical care—for help. She instructed him to sprinkle fiber powder on his breakfast and refused to let him seek medical treatment. Over the next few months, he lost 20 more pounds and finally demanded that he speak to a doctor. The doctor prescribed deworming pills. Soon after he took them, Oliver excreted a several-inches-long parasite. His stomach and intestines were irreparably damaged.
