Ebola nurse named Time magazine person of the year dies

"She made a huge contribution to MSF's work at the height of the outbreak in Monrovia."

The outbreak in West Africa was the deadliest ever of the virus, with about 11,300 people killed. Ebola is spread through bodily contact with the fluids of someone sick enough to show symptoms.

While the World Health Organisation declared an end to the outbreak in June 2016, some Liberians still wrongly fear that survivors can transmit the virus.

Tolbert Nyenswah, the man who led Liberia's Ebola fight and now heads the country's newly established National Public Health Institute, said he could not confirm reports that health workers were frightened to treat Karwah because of her Ebola survivor status as she suffered seizures.

He said the death was being fully investigated to know "what really went wrong."

"Normally if a caesarian section is conducted, the person is supposed to stay in the hospital for seven days and monitored to see whether there are complications," Tolbert said. "But to my understanding, that protocol was breached; she spent less than that in the hospital and was discharged, and when she was facing complications her husband took her back to the hospital to seek further care."
