CDC Reports Recent Surge in Deadly Brain Fungus Cases

The U.S. Centers for Disease Control and Prevention has said in a recent report that healthcare officials and providers should be aware of a rare but deadly fungal infection that can affect the brain and has seen a surge in recent years.

Published on Oct. 2, the agency’s Morbidity and Mortality Weekly Report called for greater surveillance of Cladophialophora bantiana, which U.S. officials have said is known to cause brain abscesses.

According to the report, the infection is linked to a 60 to 70 percent fatality rate. However, CDC researchers said in the report that national surveillance efforts currently don’t exist, and that the fungus’s “environmental reservoir” as well as the “route of infection” is not completely known.

Between January 2009 and July 2026, there have been 48 confirmed cases and one possible case of Cladophialophora bantiana found in samples obtained primarily from central nervous system tissue, the CDC said.

But from 2023 to 2025, “detections of the fungus increased approximately fourfold,” according to the CDC report.

Researchers said that it’s not clear why there has been an increase in recent years but stressed that more research into its risk factors “and potentially evolving virulence are warranted.”

In patients with a brain abscess, healthcare providers should now consider whether it’s due to a fungus, the report said, adding that infected people will require prompt antifungal therapy and possible surgery.

“Surgical excision might improve patient outcomes,” it said. Meanwhile, “patients with infection require prompt antifungal therapy, and surgical excision might improve patient outcomes,” it added.

Led by Joshua Lieberman of the University of Washington School of Medicine in Seattle, the researchers added that the presumed route of infection is inhalation of the fungus or direct inoculation following a skin injury.

The fungus “is a rare but important cause of brain abscess in both healthy and immunosuppressed people,” Lieberman told MedPage Today in an interview published on Oct. 5, adding that the reason it goes to the brain is “a little bit of a mystery.”

What is worrying about the infection, he added, is that “people who have apparently healthy immune systems get the infection and are also at high risk of death.”

“It’s alarming that it occurs outside of those typical high-risk populations who have pretty profound immunosuppression,” Lieberman stated.

The median age of those who contracted the infection was 68 years, according to the CDC report.

Cases have been found in 21 states across the United States, as well as the District of Columbia, the CDC report said. California had the most, with six cases, while Florida and Texas each reported five, and Pennsylvania confirmed four.

Aside from Cladophialophora bantiana, the CDC has also issued reports about a drug-resistant type of fungus known as Candida auris, which is a yeast that is known to spread in healthcare settings.

In data published in August, the health agency said Candida auris has been found in 27 states so far in 2026, with more than 3,400 cases reported. That figure is fewer than the more than 6,300 cases reported throughout all of 2024.
