A deadly fungal epidemic in Brazil is evolving fast: pollution, cats, and genetics may be fueling its unstoppable spread.

Brazil is facing the world’s largest and most persistent sporotrichosis epidemic, a fungal infection spread primarily through cats. A new study reveals an alarming genetic diversity in the fungus, suggesting that urban pollutants may be accelerating its evolution. Researchers identified molecular markers that could enhance diagnostics and treatments, while also highlighting the rapid adaptation and virulence of Sporothrix brasiliensis.
