Drug-Resistant Fungi Threaten Treasure Coast ICU Patients as Treatments Dwindle

Treasure Coast patients who end up in intensive care already face steep odds — and a growing global threat could quietly make those odds worse. Drug-resistant fungi are spreading, scientists warn, and medicine has almost no new weapons to fight them.

A coalition of 50 researchers from Brazil to Nigeria to China this week published a call to action in the journal Nature Medicine, urging governments and health systems to treat drug-resistant fungi as the serious public health emergency they say it already is. For local hospitals such as Cleveland Clinic Martin North and HCA Florida Tradition Hospital, which routinely care for immunocompromised patients — cancer survivors, transplant recipients, people living with HIV — the warning carries direct relevance.

"There's a 'silent surge' in drug-resistant fungi and it's mostly happening under the radar," said Paul Verweij, professor of clinical mycology at Radboud University Medical Center in the Netherlands and lead voice behind the Nature Medicine paper. Verweij has worked on fungal disease for more than 20 years.

Agriculture is an unexpected root of the crisis. Fungicides sprayed on crops worldwide — from watermelons to wheat — are chemically similar to azoles, the most widely used class of antifungal drugs given to patients. When fungi develop resistance to agricultural sprays, they simultaneously become harder to kill in human bodies. Fungal spores, Verweij explained, are carried into high-altitude jet streams and can travel across continents, meaning resistance that develops on a farm in one hemisphere can appear in a hospital on another.

The biology makes the problem especially stubborn. Unlike bacteria or viruses, fungi are structurally close to human cells — making it difficult to design drugs that destroy the fungus without harming the patient. In 75 years of modern medicine, scientists have developed only five classes of antifungal drugs. Patients infected with an azole-resistant fungal strain face roughly a 20% higher risk of death compared to those with drug-sensitive infections, Verweij's research found.

A second category of concern involves drug-resistant skin fungus, including the newly emergent species Trichophyton indotineae. It does not kill, but patients have suffered active infections for four years or more without clearing them, the paper notes.

The World Health Organization published its first-ever fungal pathogen priority list in 2022, a development Verweij called a turning point. Researchers are now pressing for surveillance networks, better diagnostic tools, and mandatory cross-resistance assessments before new agricultural fungicides reach the market.

St. Lucie and Indian River county residents with questions about fungal infection risk — particularly those who are immunocompromised — are encouraged to speak with their primary care provider.
