"We all know that Covid-19 is affecting many organs in the body like the brain, heart and abdominal system. That means even those who have recovered might develop complications, hence the need for seriousness in handling the pandemic.
"We also send our condolences to the family and we regret losing such a dedicated health worker to the pandemic," he said.
Medics need to ensure they use protective equipment correctly and consistently, he said.
Dr Antony Akoto, chairman of KMPDU Western region, called on the state to protect medics.
"Adisa will forever remain hero for her bravery, dying in the line of duty

After her own retirement, she used to depend on her daughter, she said.
"We as a family will greatly miss the laughter our daughter created and the united she always brought to the family," her mother said, weeping.
