Traces the life of physician and anthropologist Paul Farmer with particular focus on his work fighting tuberculosis, especially in Haiti, Peru, and Russia.

"Farmer first visited the Western African Ebola virus epidemic site in July 2014, and much of the book is devoted to his personal experiences. Reviewing the outbreak in 2020, he noted that there were almost no Ebola deaths in the U.S. or Europe. By Farmer's account, the West Africa Ebola death toll arose from the longstanding failure to invest in basic health infrastructure which resulted in a lack of proper medical care. Looking at the history of West Africa, Farmer blames the almost five centuries of European rule that resulted in the "rapacious extraction — of rubber latex, timber, minerals, gold, diamonds and human chattel" for the country's inability to provide adequate health care" (Wikipedia).
