Mr. Idris added that six additional people, who came in contact with Mr. Sawyer, have been quarantined but have not shown signs of the disease.
The government has stepped up its effort to trace all those that came in contact with the Liberian.
The second confirmed case of infection after Mr Sawyer was a doctor at a Lagos private hospital. The doctor treated the Liberian after he fell ill at the Murtala Muhammed Airport on his way to attend an ECOWAS conference in Calabar.
