Sefarien Manzanza, a civil society leader, told Reuters the situation was alarming as the number of infected people continued to rise.
“Panzi is a rural health zone, so there is a problem with the supply of medicines,” he said.
A spokesman for the African region of the World Health Organization (WHO) told the BBC that they had “sent a team to a remote area to collect samples for laboratory tests”.
The authorities called on the population to remain calm and vigilant.
They urged people to wash their hands with soap, avoid mass gatherings and not touch the bodies of the dead without qualified medical personnel.
A local MP told Top Congo Radio that about 67 people fell ill and died between November 10 and 26.
“It should be noted that Panzi Hospital does not have enough medicines to fight this epidemic. We really need help,” said the deputy.
The central African country is also dealing with a major smallpox outbreak. Between January and July of this year, they recorded about 14,500 infections.
DR Congo has also struggled with Ebola outbreaks for years.
