Infectious Diseases and Diabetes


  • Diabetes is commonly associated with an increased risk of certain infections; however, good data to support this contention is often slim for many conditions.
  • According to Boyko and Lipsky[1] (contains review of epidemiological data and risks), "probable" means data support the association, "possible" means presence or absence of the association cannot be confirmed from available information, and "doubtful" indicates that data does not support a link.

Increased Risk of Infection:

    • Probable: asymptomatic bacteriuria, lower extremity infections, increased post-surgical infections after sternotomy or total hip replacement, Group B streptococcal infections and reactivation TB in American Indians.
    • Possible: genitourinary infections such as bacterial cystitis, pyelonephritis, candidal vaginitis; respiratory tract infections including pneumonia, influenza, chronic bronchitis, primary or reactivation TB, zygomycete infections (e.g., mucormycosis), malignant otitis media; Fournier’s gangrene.
    • Doubtful: S. aureus infections, chronic sinusitis.
