Overview
- CDC surveillance for 2025 tallies at least 7,000 confirmed infections, with reports spanning 27 states in hospitals and long-term care facilities.
- Case concentrations are highest in Nevada (1,605), California (1,524) and Texas (811), while CDC tables note incomplete data for Alabama and Florida.
- Experts warn many strains resist standard antifungal drugs, leaving some patients with few or no effective treatment options, according to Melissa Nolan of the University of South Carolina.
- A July analysis centered on Nevada and Florida reported severe illness markers: over half of patients required ICU care, more than one-third needed mechanical ventilation and over half received transfusions.
- Past CDC estimates put crude mortality among infected patients at roughly 30%–60%, and researchers have proposed a developing hypothesis that rising temperatures may be aiding fungal adaptation.
