A patient was diagnosed with black fungus at Dhaka Medical College Hospital on Monday, the chief of the public hospital said.
DMCH Director Brig Gen Dr Nazmul Haque said, "The patient had post-Covid symptoms and was diagnosed with black fungus after undergoing surgery."
This was the third black fungus case detected in the capital and the first at DMCH.
The 45-year-old patient from Khulna was admitted to DMCH a week ago with post-Covid-19 complications.
After a recent surgery, the doctors suspected black fungus in his body. They confirmed it after testing samples collected from the patient.
On May 25, the first two cases of black fungus or mucormycosis were detected at the capital's Birdem General Hospital in patients who recovered from Covid-19.
Black fungus, a rare infection, has a mortality rate of 50% "with some only saved by removing an eye." The fungus affects areas of the body including the eyes, nose, face, lungs, and even the brain in severe cases.
However, in recent months, India, whose states have been told to declare the disease an epidemic, saw thousands of cases affecting recovered and recovering Covid-19 patients, according to BBC reports.
