CDC studying why a deadly bacteria is being found in more doctor's offices

The Centers for Disease Control is worried about an increase in the number of people contracting the potentially deadly bacteria C. difficile.

C. difficile is usually found in hospitals, but a study published Wednesday in the New England Journal of Medicine said that 150,000 people who had not been in a hospital came down with C. diff in 2011, and 82 percent had visited a doctor's or dentist's office in the 12 weeks before becoming ill, CNN reports. Nearly half a million Americans are infected every year, with 15,000 deaths attributed to the bacteria. Researchers say the best way to avoid getting it is by washing hands with soap and water after visiting a doctor's office.

In 2013, researchers found C. diff in six out of seven outpatient clinics tested in Ohio, on chairs and exam tables. The CDC plans to do another study to see just why the numbers are so high outside of hospitals and to determine how many people arrive at the doctor's office already with the bacteria. "This is really an important issue," Dr. Cliff McDonald, a medical epidemiologist at the CDC, told CNN. "We need to understand better how people are getting C. diff."
