A new study presented at the annual ID Week conference has found that white patients face a significantly higher risk of dying from Clostridium difficile—a dangerous bacterium that causes severe and often deadly diarrhea—compared to Black or Hispanic patients.
According to the study, about 84% of deaths from Clostridium difficile infections (CDI) occur among white patients. Researchers said the infection, which attacks the colon and causes intense diarrhea, is proving to be more fatal in white people than in other racial groups.
In contrast, the mortality rate among Black patients stands at 8%, while Hispanic patients have less than 6%, suggesting a striking racial disparity in the infection’s fatal outcomes.
Findings presented at ID week in Atlanta
The findings were shared on Sunday at ID Week, the annual joint meeting of America’s leading infectious disease professional societies, held in Atlanta, USA.
Experts at the event emphasized the urgent need to understand why this bacterial infection impacts certain racial groups more severely than others.
Urban areas more affected
Researchers also noted that Clostridium difficile infections are more common among people living in urban and metropolitan regions. Around 84% of total deaths linked to the infection occurred in large cities, indicating that urban populations are at greater risk of exposure or severe illness.
What is clostridium difficile?
Clostridium difficile (commonly known as C. diff) is a bacterium that can cause life-threatening inflammation of the colon. It spreads primarily through contact with contaminated surfaces or after prolonged use of antibiotics that disrupt the gut’s natural bacterial balance.
While infections can affect anyone, elderly patients and those with weakened immune systems are considered particularly vulnerable.
The study highlights a growing concern in public health about racial disparities in infectious diseases. Researchers suggest further investigation into genetic, environmental, and healthcare access factors that may explain the higher mortality rate among white patients.
Public health experts say understanding these differences could help improve treatment strategies and reduce preventable deaths from this dangerous infection.
