This study examined cases where fungal infections caused by Candida persisted in the bloodstream even after starting antifungal treatment. Researchers compared 46 patients with persistent infections to 92 control patients without persistent infections across three major medical centers. Patients with persistent candidemia were younger, more likely to be female, had more health complications, and sadly had much higher death rates (54% vs 31%) within 90 days. The findings suggest that certain patient characteristics and fungal species types may help identify those at higher risk of persistent infections.
