Abuja: The first Nigerian confirmed to have contracted the Ebola virus has been discharged after making a full recovery, the government said.

Minister of Health, Onyebuchi Chukwu, told reporters late Saturday in Lagos, the country’s economic hub, that the patient had been discharged after conclusive protocols, Xinhua reported.

Five other Ebola patients have also almost fully recovered, Chukwu said.

He said Nigeria had recorded 12 confirmed cases, four of whom have died, while 189 people are under surveillance in Lagos, and six in the southeastern state of Enugu.

According to the minister, all the people under surveillance had been in secondary contact with the infected, and all the patients being treated have now been moved to the new 40-bed isolated ward in Lagos.

The minister also said the Nano-silver drug which was made available to the Emergency Operations Centre in Lagos on August 14, did not meet basic research requirements.

Chukwu denied the rumour of the Ebola virus in Imo, Abia and Cross River states.

Patrick Sawyer, a Liberian national, brought the Ebola virus into the country. It has killed more than 1,000 people in West Africa.

Sawyer died on July 20 and the female doctor who attended to him also died on July 25 after becoming infected.
