New Delhi: Amid growing concern over the rise in the number of cases of mucormycosis or black fungus, top doctors aiding the Central Government in the fight against Covid-19 on Saturday said the misuse of steroids is a major cause behind this infection.


All India Institute of Medical Sciences (AIIMS) Director Dr Randeep Guleria, who briefed in this regard, said the “chances of fungal infection increase in the patients who are diabetic, Covid positive and are taking steroids”.


“To prevent it, we should stop the misuse of steroids,” he added.


Talking about the ill-effects of black fungus, Dr Guleria said” “This disease can affect the face, infecting nose, orbit of eye or brain, which can cause even vision loss. It can also spread to the lung.”

The AIIMS Director also warned of a surge in fungal infection in the Covid-19 patients.


“As Covid-19 cases are increasing, it is of paramount importance that we follow protocols of infection control practices at the hospitals. It is been seen that secondary infections -- fungal and bacterial -- are causing more mortality,” he said.


Meanwhile, Union Health Ministry Joint Secretary Lav Aggarwal informed the overall positivity rate in India has now declined and said the “containment efforts are working”.


“Overall positivity rate in India, which stood at 21.9% last week has now fallen to 19.8%. Delhi, Chhattisgarh, Daman and Diu, Haryana and Madhya Pradesh have reported a major drop in case positivity,” he added.


Aggarwal further said 11 states have over one lakh active cases, eight states have 50,000 to one lakh active cases and 17 states have less than 50,000 cases.


“Maharashtra, UP, Gujarat and Chhattisgarh where high number of cases are being reported are also reporting a decline in active cases,” he added.


The Joint Secretary, however, expressed concern with regard to Tamil Nadu where a “rise in number of active cases has been reported in the last one week”.
