Investigations are still being carried out into how the Ebola virus - which killed 49 people in DRC during a three-month outbreak in 2014 - suddenly occured in the equatorial forest region of Bas-Uele province, more reports emerging from Congo say.
He said in response to the announcement by the WHO on confirmed cases of Ebola in the Democratic Republic of Congo (DRC), government had directed health officials stationed at the ports, to step up inspection activities. At present, 25 contacts of the second patient who died are being followed.
The Ebola virus was first discovered near the River Ebola in 1976 in northern Democratic Republic of Congo, then known as Zaire.
Health officials are attempting to find 125 people who they believe to be connected to the identified cases in the northeastern part of Congo, WHO's Congo spokesman Eugene Kabambi told Reuters.
He said the symptoms to look out for included fever, fatigue, weakness, dizziness and muscle aches.
On Saturday, Dr. Matshidiso Moeti, WHO's regional director for Africa, met with national authorities in Kinshasa to discuss ways to mount a response to the outbreak.
WHO said it was working with DRC officials and sending health workers to help deal with the crisis. The 1,400-kilometer (870-mile) route from Kinshasa to Likati is remote and isolated with limited transportation networks, requiring two to three days of travel.
A team of experts is on its way to the area, and health workers will be supplied with protective equipment, WHO said.
World Health Organization declared Guinea, Liberia and Sierra Leone - the three countries that had been most effected by the epidemic - to be free of Ebola in 2016.
In June a year ago World Health Organization declared Liberia free of active Ebola virus transmission.
The GAVI vaccine alliance said Friday that about 300,000 emergency doses of an Ebola vaccine could be available in case of a severe outbreak, and was ready to support the Congolese government. He insisted that people must bear in mind that Tanzania was not immune to a possible Ebola outbreak despite the fact that the latest cases of the disease have been reported far away in the DR Congo, at the border with the Central African Republic (CAR).
