Researchers in Shanghai studied 33 patients with deep skin fungal infections that had become increasingly common in the area. They identified 13 different fungal species causing these infections, most commonly Candida parapsilosis, Trichophyton rubrum, and Sporothrix schenckii. Patients were treated with antifungal medications tailored to the specific fungus and its drug sensitivity, with most patients recovering completely, though some experienced relapses, emphasizing the importance of long-term follow-up care.
