The infection was the latest health scare for America's 42nd president. In 2004, at age 58, he underwent a quadruple bypass operation after doctors found signs of extensive heart disease.
Six years later he had stents implanted in his coronary artery.
This prompted him to adopt a vegetarian diet and to speak out publicly about how his change in food consumption helped him get healthier.
"Maybe if I had... not eaten so many hamburgers and steaks, which I love, maybe if I had, you know, had slightly less stress in my life... maybe it would have been different," Clinton told ABC News in 2004 after his successful heart surgery.
In the two decades since leaving the White House after two presidential terms, he has thrown himself into numerous humanitarian and diplomatic causes.
He travelled the world, not just to receive generous speaking fees and to attend conferences but to visit disaster areas or raise funds for the fight against AIDS.
Clinton, who once called himself "the comeback kid" during the 1992 Democratic Party primary battle, remains involved in his Clinton Foundation and supported his wife's unsuccessful campaign against Donald Trump five years ago.
Gradually his pace has slowed, and he has been travelling less in recent years.
The Clintons currently live in Chappaqua, New York.
