Margaret Kilelu is admitted in the Intensive Care Unit at Coast Provincial General Hospital (CPGH).
These revelations are emerging three days after the Amref-Kenya nurse was reported missing on.
Her family said a Good Samaritan found her near a petrol station in Bamburi and reported the incident to the Kadzandani Police Station.
Before Ms Margaret Kilelu’s disappearance, the family said that she had been hospitalised at Kenyatta National Hospital with a depression-related illness.
She disappeared on Thursday at Tena Estate in Nairobi.
The family says they are still piecing together details to establish how she travelled to the Coast from Nairobi.
“According to information from the hospital …she was brought on Saturday morning by police officers. This after the Good Samaritan reported the matter to them,” said Mr Chrispin Chombo, the nurse’s brother.
“When we got here we found her unconscious and we took her to Jocham Hospital for scanning where she was found to be okay. [Then we returned] her to CPGH,” said Mr Chombo.
According to CPGH chief administrator Iqbal Khandwala, preliminary assessment revealed that there might be infection in her blood which the patient is being treated for.
“She will need to go for toxicology assessment to find out if she was intoxicated or poisoned. Currently, her condition is improving but she has not been able to speak,” said Dr Khandwala.
