A third doctor has passed away due to the coronavirus in Karachi, according to Pakistan Medical Association Secretary General Dr Qaiser Sajjad.

Dr Furqan — who had recently retired from the Karachi Institute of Heart Diseases — was unable to get treatment despite visiting several hospitals, he said.

"He had tested positive for the virus around four days ago and had self-isolated at home. But because he had heart troubles, he was facing difficulty in breathing."

He tried to get himself admitted to any of the isolation wards but was unable to receive medical treatment, he added.

"If a doctor in the city cannot be given a ventilator then what will happen to common citizens," Dr Sajjad questioned.
