A Norwegian doctor, who was infected with the Ebola virus in Sierra Leone, has been discharged from hospital after recovery from the deadly disease, doctors at Oslo's Ulleval hospital said.

After two weeks of medical treatment, doctors at the hospital's infectious diseases department concluded that the patient, Silje Michalsen, has recovered, Xinhua reported Monday.

"I am healthy and not contagious and I do not feel as if I have had Ebola," said Michalsen at a press conference at the hospital.

Michalsen, a doctor from the the Harstad hospital in north Norway, had been working for Doctors Without Borders in Sierra Leone for months when she developed a fever Oct 2 and tested Ebola positive the next day.

The 30-year-old said that she was happy with her fast evacuation Oct 6 from Sierra Leone to Norway for treatment.

The two local colleagues of Michalsen, who were also tested Ebola positive at the same time, have already died while a third one is under treatment.

Michalsen said that she wanted to go back to work for Ebola patients in Sierra Leone as soon as possible.

She arrived in Sierra Leone July 2, 2014, one day before the first Ebola infection was detected in the country.

In the Sierra Leone city known as Bo, Michalsen participated in the development of an Ebola patient center, which was opened Sep 19.

Doctors at the Ulleval Hospital said that Michalsen was treated with an experimental medicine for Ebola not yet available on the open market. However, they refused to disclose what it is.
