What is the deadly ‘black fungus’ seen in Covid patients in India?

Usually very rare, mucormycosis has a high mortality rate and is difficult to treat

A rare black fungus that invades the brain is being increasingly seen in vulnerable patients in India, including those with Covid-19, as the health system continues to struggle in the midst of the pandemic.

The health ministry on Sunday released an advisory on how to treat the infection. In the state of Gujarat, about 300 cases had been reported in four cities, including Ahmedabad, according to data from state-run hospitals.
