Ambulance staff worker Gordon Kamara arrives at an Ebola clinic with six patients showing signs of the virus.
Since the start of the outbreak, eight people have died in Nigeria, but there have been no new confirmed cases since Sept. 8.
The news comes after WHO officially declared Senegal free of Ebola, commending the country's response as a "good example of what to do when faced with an imported case of Ebola."
