Of the 270 MM patient studies done in Diwali surge nationally, diabetes and steroid use were found to be the biggest risk factors (Representative image) AHMEDABAD/SURAT: If disease and death all around due to Covid-19 infection was not enough, Gujarat is also battling an exponential rise in deadly attack of mucormycosis (MM), also known as black fungus, which is typically pushing Covid-recovered back into ICUs and surgical wards. Those with uncontrolled diabetes and heavy use of steroid to survive Covid-19 complications are worst affected. Senior ENT surgeon Dr Navin Patel said, “A tsunami of mucormycosis is happening which threatens to kill patients who were saved from Covid. Rampant use of steroids during corona pandemic needs to be rationalized.”
