What Exactly Is C. Diff–and Why Is It Becoming More Common - Article Health

Infection with the Clostridium difficile bacterium is one of the most feared in medicine. Not only can Clostridium difficile (also called C. difficile or C. diff) cause life-threatening symptoms and even death, it is now spreading more and more easily. According to the Centers for Disease Control and Prevention (CDC), some half a million people are infected with C. diff each year and, of those, 15,000 die.

“Historically, C. diff primarily affected people who are older; however more recently, the infection is also increasing in populations that were previously not thought to be at risk, including children and younger adults,” says Alexander Khoruts, MD, spokesperson for the American Gastroenterological Association and professor of medicine at the University of Minnesota. “It is thought that there are new strains that produce more toxin and are more infectious.”

Symptoms of C. diff vary from person to person, although everyone who is infected will get watery diarrhea. In a mild case, which can quickly progress to a more serious one, a person has at least three bowel movements a day for two or more days. Severe cases may involve up to 15 bowel movements a day.

Who is at risk for C. diff?
C. diff is most common in people who take antibiotics for long periods of time, especially broad-spectrum antibiotics, those that kill numerous bacteria, says Aaron Glatt, MD, a spokesperson for the Infectious Diseases Society of America and chairman of medicine at South Nassau Communities Hospital on Long Island. Symptoms can show up as quickly as one day after starting antibiotics–or as long as two months later. More commonly, symptoms appear within five to 10 days of starting the meds.

How does C. diff spread?
C. diff spores are shed in feces, and poop in turn may contaminate surfaces where the spores can linger for months like counters, toilets, phones, and remote controls–or even food. Health care workers who have gotten C. diff on their hands because they touched a contaminated surface can pass it on to patients.
