GENEVA - A Cuban doctor who received experimental treatment for Ebola in a Geneva hospital has made a full recovery and left Switzerland to be reunited with his family, the hospital said on Saturday.

Felix Baez, 43, was one of 256 Cuban doctors and nurses whowent to West Africa to treat patients from the worst outbreak of the virus on record, which has killed more than 6,000 people.

Soon after arriving in Geneva, Baez received the Canadian experimental treatment ZMab, a precursor to the Ebola drug ZMapp, which has been used to treat several US patients.

"Two days afterwards he was already much better," Geneva's chief medical officer Jacques-Andre Romand said, addingthat the same drug had been sent to Rome to treat an Italiandoctor battling the virus.

Baez was hospitalised in Geneva at the request of the World Health Organization, which is headquartered in the city, afterhe contracted the disease in Sierra Leone, one of the countries that has been worst hit by the outbreak.

Out of 138 health care workers who have caught the disease in Sierra Leone, 106 have died, a much higher fatality rate than among health care workers in neighbouring Guinea and Liberia,WHO data published on Wednesday showed.

Two more doctors died in Sierra Leone on Friday, a government and hospital source said.

Baez, Cuba's first Ebola patient and the first case of the disease in Switzerland, was treated in isolation in the Geneva hospital for 16 days.

At no time was there any risk of transmission to the local population, Romand said.
