Black fungal infection: Symptoms and need for caution


Kollam: The Department of Health has issued a warning against black fungal infection (mucormycosis), urging those with its symptoms to seek immediate medical help.

The department advised caution against the infection, even as it said the situation was not of concern. The Indian Council of Medical Research (ICMR), however, warned that ignoring the infection could turn fatal.


Though black fungal infection is not new, authorities are concerned over the rising number of cases among COVID-19 patients. Mucormycosis, which lowers immunity, has been reported in those on medication for other diseases also.

A person gets infected when his immune system does not function well. The fungus could affect the cranial cavities or lungs.


Redness of the skin around the eyes and nose. The patient may experience pain, fever, headache, cough, breathlessness, and may vomit blood, and exhibit altered consciousness.
