The global epidemiology of invasive Candida infections--is the tide turning?

Area of Science:

• Medical Mycology
• Infectious Diseases
• Epidemiology

Background:

• Invasive candidiasis represents a major global health concern with increasing incidence over the past 50 years.
• Candida species are a leading cause of hospital-acquired bloodstream infections, posing a significant economic and clinical challenge.
• The rising prevalence of non-albicans Candida species contributes to the complexity of invasive infections.

Purpose of the Study:

• To review the epidemiology and disease burden of invasive candidiasis.
• To analyze trends in incidence, mortality, and the contribution of different Candida species.
• To highlight the economic impact and areas for future research.

Main Methods:

• Literature review of epidemiological data on invasive candidiasis.
• Analysis of trends in bloodstream infection rates and mortality from various geographic locations.
• Examination of the changing species distribution in invasive Candida infections.

Main Results:

• While bloodstream infection rates increased in the 1980s, this trend has not been sustained, with some reports indicating a decrease.
• Mortality from candidiasis has shown a downward trend in the United States since 1989.
• Non-albicans Candida species are increasingly implicated in invasive infections, alongside the persistent economic burden.

Conclusions:

• Invasive candidiasis remains a critical medical issue with a substantial economic burden, despite falling mortality rates in some regions.
• The epidemiology is complex, with geographic variations and a rising proportion of infections caused by non-albicans Candida species.
• Further research into the epidemiology and pathogenesis of these infections is essential.
