Hospitalized patients can bring home infections

In the journals

Clostridioides difficile (C. diff), a bacterium that can potentially cause diarrhea and colitis, commonly colonizes people who are hospitalized. New research suggests that even if these individuals never had symptoms and were never diagnosed with C. diff during their hospital stay, they could still bring the bacterium home and expose family members.

Using medical insurance data, researchers looked at households with at least two people on the same insurance plan and identified people who had hospital stays but were not diagnosed with C. diff. They discovered that once these individuals returned home, other household members had a 73% greater chance of needing treatment for C. diff infection within 60 days than other members of the insurance plan who did not have a recently hospitalized family member. The longer the hospital stay, the higher the infection risk; households with a family member who spent a month or longer in a hospital had almost double the risk for C. diff compared with those in which a member was hospitalized for one to three days.

The findings demonstrate the importance of practicing good hygiene after a family member returns from the hospital, including regularly washing hands with liberal amounts of soap and warm water, especially after using the bathroom and before eating. The results appeared in the May 2022 issue of Emerging Infectious Diseases.
