The World Health Organization (WHO) is to hold an emergency meeting to discuss the risk of Ebola spreading from the Democratic Republic of Congo.
A panel will decide on Friday whether to declare a “public health emergency of international concern”, which would trigger a larger response.
At least 45 people are believed to have been infected in the current outbreak and 25 deaths are being investigated.
Cases emerged in a rural area with one now confirmed in the city of Mbandaka.
The city of about one million people is a transport hub on the River Congo, prompting fears that the virus could now spread further, threatening the capital Kinshasa and surrounding countries.
Ebola is an infectious illness that causes internal bleeding and often proves fatal. It can spread rapidly through contact with small amounts of bodily fluid, and its early flu-like symptoms are not always obvious.
WHO has previously admitted that it was too slow to respond to a deadly Ebola outbreak in West Africa from 2014-2016 that killed more than 11,000 people.
Why is the case in Mbandaka a concern?
Senior WHO official Peter Salama said the spread to Mbandaka meant there was the potential for an “explosive increase” in cases.
“This is a major development in the outbreak,” he told the BBC. “We have urban Ebola, which is a very different animal from rural Ebola. The potential for an explosive increase in cases is now there.”
Mr Salama, the WHO’s deputy director-general for emergency response, said Mbandaka’s location on the River Congo raised the prospect of Ebola spreading to Congo-Brazzaville and the Central African Republic, as well as downstream to Kinshasa, which has a population of 10 million.
“This puts a whole different lens on this outbreak and gives us increased urgency to move very quickly into Mbandaka to stop this new first sign of transmission,” he said.
The 2014-16 West Africa outbreak was the most deadly outbreak of the disease because it spread to the capitals of Guinea, Sierra Leone and Liberia.
