Many Ebola survivors are likely to face further health issues including eye and joint problems, the World Health Organization has warned.
And a recent case may have caught Ebola through sexual contact with someone who had recovered, experts said.
The WHO has decided the crisis still constitutes as a public health emergency of international concern.
But said there had been “real, substantive progress” in the drive to end the outbreak in the last few weeks.
Officials announced they are attempting to set up clinics in Sierra Leone, Liberia and Guinea to monitor the health consequences Ebola survivors face.
Patients have reported problems with their vision, joints and on-going fatigue.
But Dr Bruce Aylward, assistant director general of the WHO, admitted not much was known about the long-term implications of the virus.
He said the information gathered at these clinics would help the mental and physical health needs of people recovering from the disease.
Experts from the organisation also said a recent Ebola patient was “likely to have been infected following sexual contact involving a survivor some months after his recovery”.
