The WHO said it is deploying about 30 more experts to the city.
Late Thursday, Congo's Ministry of Health announced 11 new confirmed Ebola cases and two deaths tied to cases in the country's northwest, including one in a suburb of Mbandaka.
Ilunga said of the current 25 deaths, only one has been confirmed as Ebola, adding that no new health professionals have been contaminated.
The northwest city of Mbandaka, which has a confirmed case of Ebola, is situated on the Congo River and is just a few kilometres away from capital city of Kinhasa.
The Ebola outbreak in the DRC has entered a "new phase" after it spread to a large city, Health Minister Oly Ilunga said on Wednesday.
The emergency meeting is to "consider the global risks" of the deadly Ebola virus disease, which has now moved to an urban area of DRC.
The World Health Organization has raised its assessment of the public health risk from Democratic Republic of Congo's Ebola outbreak to "very high" at the national level, from "high" previously, it said in a statement on Friday.
A ministry statement late Thursday said that the total number of Ebola cases is now 45, including 10 suspected, 21 probable and 14 confirmed.
The WHO has deployed doses of the experimental vaccine along with emergency teams and equipment Congo. Ebola is a highly infectious disease spread through contact with even small amounts of bodily fluid of an infected person.
The Commission noted that the allocated funding would "ensure deployment of relevant surge capacity to the affected areas, surveillance and contact tracing of Ebola victims as well as active case finding for early detection of those infected".
It will be used to protect health workers and "rings" of contacts around each case. The WHO has sent 4,000 doses to Congo and said it will dispatch thousands more as needed in the coming days. Under the supervision are already more than five hundred people. The virus is initially transmitted to people from wild animals, including bats and monkeys.
According to Seipone, symptoms of Ebola virus disease include a fever of acute onset (37.5oC) with unexplained bleeding tendencies from the nose (epistasis), gums, vagina, skin or eyes, bloody stools, vomiting and coughing blood, diarrhoea, deterioration of vision or decreased consciousness.
The World Health Organisation (WHO) said it was preparing for the "worst case scenario", as it responds to the Ebola outbreak in the DRC.
