Hantavirus explained: Symptoms, transmission and treatment

While rare, hantavirus outbreaks are deadly. This genus of viruses is primarily transmitted from rodents to humans. Only one strain, known as Andes virus, has been documented to potentially spread from person to person, although such transmission is rare and typically requires close contact.

Hansen’s disease, or leprosy, in Florida: What to know

Florida reports one of the highest rates of locally acquired Hansen's disease, or leprosy, in the United States. This disease affects the skin and nerves and is primarily caused by the bacteria Mycobacterium leprae. Although it is curable, the emergence of new cases has drawn the attention of medical professionals.

What is brain-colonizing fungus? Expert explains Cryptococcus neoformans

Out of the hundreds of fungal disease-causing pathogens in humans, only four are considered "critical risks" to human health. The deadliest, Cryptococcus neoformans, colonizes the brain, but can be found all around us. University of Florida Emerging Pathogens Institute member breaks down key questions surrounding this intriguing yet sinister fungus.

Honoring a prolific scholar and policy innovator: Burton H. Singer, Ph.D.

Burton H. Singer, Ph. D., a prolific member of the University of Florida Emerging Pathogens Institute, passed away on Feb. 15, 2026. With former faculty positions at Princeton University, Yale School of Public Health and Columbia University, Singer authored over 1,300 publications over seven decades.

Basal IFNλ2/3 signaling is required for ISG expression and viral control in human intestinal epithelial cells

In this study, we investigated how each type of IFNλ (IFNλ1, IFNλ2, and IFNλ3) contributes to antiviral readiness in human intestinal epithelial cells. By selectively removing each IFNλ, we discovered that IFNλ2 and IFNλ3, but not IFNλ1, are essential for maintaining this built-in antiviral state. Cells lacking IFNλ2/3 became highly vulnerable to a wide range of viruses and lost the ability to activate key antiviral genes. Our findings reveal a previously unrecognized hierarchy among IFNλs and highlight IFNλ2/3 as critical guardians of gut antiviral defense, even before infection occurs.

Persistence of human norovirus and Escherichia coli in preharvest agricultural water

Human norovirus (HuNoV) is the leading cause of foodborne illnesses in the United States, recognized for its environmental persistence and sanitizer resistance. However, limited data exist on its persistence in agricultural water. This study assessed the survival of HuNoV GII, its cultivable surrogate Tulane virus, and Escherichia coli TVS 353 in preharvest agricultural water collected from a Florida farm (treatment) compared with phosphate-buffered dilution water (BPDW, control). These findings demonstrate the long-term persistence of enteric pathogens in preharvest agricultural water and underscore the critical need for risk-based water safety strategies.

Whooping cough in Florida: What to know

Whooping cough affects the upper respiratory tract. A bacterial infection by Bordetella pertussis damages the airways, leading to severe and uncontrollable coughing fits. It's most dangerous to children, especially infants under 12 months of age.
