Karnataka Health Minister K Sudhakar on Sunday said it has been decided to start treatment for “black fungus” at Bowring Hospital here on a pilot basis, and later extend the treatment to medical colleges and district hospitals. Noting that the treatment for black fungus infection is a bit costly, the Minister said he would discuss with Chief Minister BS Yediyurappa regarding free treatment as he has also said a committee of experts would be set up to prepare a blueprint for treatment.
