Emerging and reemerging microbial threats. Nosocomial fungal infections

Area of Science:

• Medical Mycology
• Infectious Diseases Epidemiology
• Hospital-Acquired Infections

Background:

• Nosocomial fungal infections were once considered minor but are now recognized as a significant cause of illness and death.
• A substantial increase in the incidence of hospital-acquired fungal infections has been observed over the past quarter-century.

Purpose of the Study:

• To analyze the trends and characteristics of nosocomial fungal infections from 1980 to 1990.
• To quantify the rise in incidence and identify common fungal pathogens responsible for these infections.

Main Methods:

• Retrospective analysis of 30,447 cases of nosocomial fungal infections.
• Data collected over a ten-year period (1980-1990).

Main Results:

• Nosocomial fungal infection incidence increased by 90% to 175% between 1980 and 1990.
• Infection rates escalated from 2.0 to 6.6 per 1000 discharges.
• Infections were prevalent in surgical wounds, lungs, urinary tracts, and bloodstream.
• Candida species were the most common pathogens (78.3%), followed by Torulopsis (7.3%) and Aspergillus (1.3%).

Conclusions:

• Nosocomial fungal infections represent a growing and serious clinical threat.
• Fungal pathogens, particularly Candida species, are major contributors to hospital-acquired infections, morbidity, and mortality.
