A member of staff of West African regional economic body Ecowas this week became the third person in Nigeria to die of the disease, which has no proven cure. The current outbreak has killed more than 1,000 people across four West African countries.
"Eight (others) are still alive, more than half of them are doing very well and actually showing signs of recovery ... under treatment," Chukwu said.
However, Chukwu said that after initial screening, it was determined that only six people had been in contact with her, and they put those six under surveillance.
A total of 169 people were being monitored in Lagos, after eight others were cleared, including all of Sawyer's primary contacts from when he entered the country.
