According to WHO, the country's health minister requested the United Nations agency's support after one of five blood specimens tested positive for the Ebola virus disease.
Another WHO spokesman, Eric Kabambi, said: "The case is in a very remote zone, very forested, so we are a little lucky".
The disease was first identified in 1976.
A wider outbreak occurred in Guinea, Sierra Leone and Liberia in 2014-2015, killing more than 11,000 people.
A spokesperson for the World Health Organization toldReuters on Friday that a person in the Democratic Republic of Congo had died after becoming infected with Ebola, a contagious virus that causes hemorrhagic fever.
Instead, they said it should be given to those who have close contacts with Ebola patients, the contacts of those contacts, and the local and worldwide health workers who might be treating anyone infected with Ebola.
Now health officials are considering whether to deploy an experimental Ebolavaccine against the outbreak, for the first time since the WHO gave it preliminary approval in April.
The vaccine was tested in a trial involving almost 12,000 people in Guinea and Sierra Leone during 2015 and 2016.
"The fact that this is a country that has experience dealing with Ebola should give us hope that we won't see a pandemic on the scale of the 2014 outbreak that hit West Africa", Dr. Seth Berkley, Gavi CEO, said in a statement.

This followed the outbreak of the disease in Congo.
The health minister, therefore, directed that all Nigerian health workers should maintain a high index of suspicion by screening all fevers for Ebola. Of those who received the vaccine immediately, none developed the Ebola virus.
World Health Organization has faced criticism in the past for its failure to tackle outbreaks due to its slow response. "We've shown that by working collaboratively, across global borders and sectors, we can develop and test vaccines rapidly and use them to help bring epidemics to an end".
According to Director General of Police N Sambasiva Rao, systems using the Windows operating system were hit by the cyber attack. Elsewhere in Europe, the attack hit companies including Spain's Telefonica, a global broadband and telecommunications company.
