Potentially Hazardous Fungus Spreading in Tennessee
Health officials in Tennessee have issued a warning about a possibly dangerous fungus spreading throughout the state.
Over a three-month span, more than 35 cases of histoplasmosis—an infection of the lungs caused by the fungus Histoplasma capsulatum—have been reported in the Maury-Williamson County area, according to data released on January 12 by the Tennessee Department of Health.
Local reports indicate that a woman died after contracting histoplasmosis, showing positive results just two days post-mortem. However, epidemiologists from the state shared during a recent meeting with the Williamson County Commission that investigations are still ongoing and that there is no definitive proof linking the infection to the death.
Notably, the average age of individuals affected by this outbreak is about 50 years old.
State officials clarify that the fungus typically thrives in soil associated with bird and bat droppings. People become exposed when they inhale the fungal spores. As of now, no singular source has been pinpointed for the infections in Tennessee.
While many people remain asymptomatic, histoplasmosis can manifest respiratory symptoms ranging from mild to severe, as per the CDC.
Symptoms may include fever, cough, extreme fatigue, headaches, body aches, chills, and chest pain, appearing typically between 3 to 17 days after exposure.
“Histoplasmosis can be fatal for certain patients, but it doesn’t have to be.”
Since these symptoms mimic those of a common cold or flu, they can often be mistaken or ignored, leading to potential delays in diagnosis.
Dr. Zaid Fadul, CEO of Bespoke Concierge MD in California, points out that most individuals aren’t in a high-risk category. “In many cases, the amount of spores we breathe in is quite minimal, so we often don’t fall ill—assuming we’re not exposed for long periods outdoors,” he explained.
Those at higher risk include individuals with compromised immune systems or who have high exposure to spores. “When the immune system falters, histoplasmosis can escalate into a life-threatening condition,” he cautioned.
While most cases do not need treatment, severe instances might require antifungal medication. Some patients in Tennessee have been hospitalized, with several reported in critical condition during a recent news briefing.
Diagnosis involves testing blood or urine samples in a laboratory, though other methods such as analyzing respiratory fluids, X-rays, CT scans, or tissue biopsies may also be utilized.
To reduce the risk of infection, officials advise minimizing activities in areas where soil gets disturbed and possibly wearing masks during outdoor work—especially in dusty conditions.
“Being outdoors is great for health, but if you’re in a dusty environment or staying outside for extended periods, it’s wise to wear a mask to reduce the inhalation of spores,” Fadul recommended.
Before this outbreak, histoplasmosis had only been classified as a “reportable disease” in 14 states, including Arkansas, Delaware, and Pennsylvania.
This infection is not spread between humans and cannot be transmitted between humans and animals.
If someone develops symptoms and suspects exposure to Histoplasma, contacting a doctor for appropriate tests is crucial, especially if antibiotic treatments are ineffective.
“This outbreak, along with the CDC-approved antigen tests, should facilitate quicker diagnoses and treatments for unclear respiratory issues,” Fadul noted. “Histoplasmosis can indeed be deadly for certain patients, but it doesn’t have to be.”
