Candida krusei transmission among hematology patients resolved by adapted antifungal prophylaxis and infection control measures.

A sudden increase in neutropenic hematology patients with Candida krusei colonization and bacteremia prompted a longitudinal epidemiological investigation. We identified 39 patients; 13 developed candidemia, and three died; 25 patients carried the same genotype. We intervened by changing antifungal prophylaxis and implementing strict infection control measures. The incidence dropped immediately.
