The head of the World Health Organisation on Saturday visited eastern Congo's Bunia, a city at the heart of an outbreak of a rare type of Ebola, where the virus is spreading faster than the response despite better-organised health facilities and new aid arrivals.
Tedros Adhanom Ghebreyesus is expected to visit a treatment centre and meet local authorities, health workers and affected families in Bunia.
"The best way to address this is to provide all the necessary support to fight the disease at its epicentre and to continue offering every assistance needed," the WHO's director-general told reporters late Friday.
The health organisation said latest official figures showed 906 suspected cases and 223 suspected deaths. Neighbouring Uganda has confirmed nine cases and one death, the Ugandan ministry of health said Friday.
The Bundibugyo virus, the current kind of Ebola, has no approved treatment or vaccine.
"This is a difficult situation, and we recognise that. But the Democratic Republic of Congo has faced the Ebola virus many times before. We are confident that it can once again bring this outbreak under control," Tedros said after meeting with Congo's Prime Minister Judith Suminwa Tuluka on Friday.
Medical aid donated by the European Union arrived in Ituri, the heart of Congo's Ebola outbreak, on Thursday. More shipments are expected in the coming days. The US announced USD 80 million in additional aid on the same day, bringing its total commitment to more than USD 112 million.
Response efforts at Bunia's Rwampara and General hospitals appear more organised, with additional staff, protective gear and medical supplies, though patients continue arriving around the clock, a reporter from The Associated Press observed on Friday.
The response has not kept pace with one of the fastest-spreading outbreaks on record, Doctors Without Borders, or MSF, warned on Saturday.
"Never before has an Ebola outbreak recorded so many cases so soon after its declaration," Dr. Alan Gonzalez, MSF's deputy director of operations, said in a statement. "Nobody knows the true scale and severity of this outbreak."
Gonzalez called for an immediate expansion of testing, faster deployment of aid workers and sustained access for medical supplies.
The dangers faced by health workers have been heightened by anger among residents over the stringent medical protocols for handling the victims' bodies, which clash with local burial rites. Residents have launched at least three attacks against health centres.
Attacks in Ituri by the Allied Democratic Forces, a rebel group allied with the Islamic State group, and a coalition of ethnic militias have also hindered the response.
The illness also has been reported in the Congolese provinces of North Kivu and South Kivu, south of Ituri, where the Rwanda-backed M23 rebel group controls many key cities, including Goma and Bukavu. The rebels have reported two cases.
Uganda and Rwanda have closed their borders, while the Trump administration last week banned entry of non-US passport holders who had recently visited Congo, Uganda or South Sudan.
Border closures and travel bans are "not effective at all" in preventing the spread of the outbreak, Tedros said on Friday.
"Closing borders, as some countries have done, only discourages transparency. The Democratic Republic of Congo is reporting the situation openly and transparently," he said, urging countries to reconsider these measures.
