Cow dung to ward of virus

India's doctors warn against using cow dung to ward off coronavirus

The Indian government has told medics to look out for signs of mucormycosis in coronavirus patients following an increase in cases of the rare but potentially fatal infection.

The disease can lead to blackening or discolouration over the nose, blurred or double vision, chest pain, breathing difficulties and coughing blood.

It is strongly linked to diabetes, which can in turn be exacerbated by steroids, such as dexamethasone, used to treat severe COVID-19.
