Hospital-Associated Multicenter Outbreak of Emerging Fungus Candida auris, Colombia, 2016
Abstract:
Candida auris is an emerging multidrug-resistant fungus that causes hospital-associated outbreaks of invasive infections with high death rates. During 2015-2016, health authorities in Colombia detected an outbreak of C. auris. We conducted an investigation to characterize the epidemiology, transmission mechanisms, and reservoirs of this organism. We investigated 4 hospitals with confirmed cases of C. auris candidemia in 3 cities in Colombia. We abstracted medical records and collected swabs from contemporaneously hospitalized patients to assess for skin colonization. We identified 40 cases; median patient age was 23 years (IQR 4 months-56 years). Twelve (30%) patients were <1 year of age, and 24 (60%) were male. The 30-day mortality was 43%. Cases clustered in time and location; axilla and groin were the most commonly colonized sites. Temporal and spatial clustering of cases and skin colonization suggest person-to-person transmission of C. auris. These cases highlight the importance of adherence to infection control recommendations.
Insights
A multidrug-resistant fungus, Candida auris, caused a deadly outbreak in Colombia. Person-to-person transmission in hospitals was suggested by case clustering and skin colonization, emphasizing infection control.
Area of Science:
- Infectious Diseases
- Mycology
- Epidemiology
Background:
- Candida auris is an emerging multidrug-resistant fungus.
- It causes severe hospital-associated invasive infections with high mortality rates.
Observation:
- An outbreak of Candida auris (C. auris) occurred in Colombia during 2015-2016.
- 40 cases of C. auris candidemia were identified across 4 hospitals in 3 cities.
- Patients were predominantly young (median age 23 years, 30% <1 year) and male (60%).
Findings:
- The 30-day mortality rate was high at 43%.
- Cases exhibited temporal and spatial clustering.
- The axilla and groin were the most common sites of skin colonization.
- Evidence suggests person-to-person transmission.
Implications:
- This study highlights the significant threat of C. auris in healthcare settings.
- Findings underscore the critical importance of strict adherence to infection control protocols.
- Further research into transmission dynamics and reservoir identification is warranted.
