In February 2013, 23-year-old Peace Corps volunteer Nick Castle died in a hospital at West China Hospital of Sichuan University of a gastrointestinal illness. He had fallen into a coma after feeling sick for months, losing weight and, finally, collapsing in Chengdu, the capital of the Sichuan province. Carrie Hessler-Radelet, the director of the Peace Corps in 2013, told the New York Times that the agency had been examining and revising its entire practice since the death of another volunteer in Morocco in 2009.

Deaths in the Peace Corps are not frequent, but they rightly call into question the program's training processes, medical resources, and the security of volunteers.
