Mr Ghebreyesus noted that the organisation previously assessed the outbreak risk as high nationally and regionally, and low globally, but has now revised it to “very high” at the national level, “high” regionally and “low” globally
The World Health Organisation (WHO) has raised the risk level of the ongoing Ebola outbreak in the Democratic Republic of the Congo to “very high” nationally as suspected cases approach 750, with the disease already spreading across borders into Uganda.
WHO Director-General Tedros Ghebreyesus announced the updated assessment on Friday during a Member State information session on the Ebola outbreak and a separate hantavirus outbreak linked to the cruise ship MV Hondius.
According to the WHO, DRC has recorded 82 confirmed Ebola cases so far.
However, the agency said the outbreak is likely far larger, with nearly 750 suspected cases and 177 suspected deaths already reported.
“In Uganda, two cases have been confirmed in people who travelled from DRC, with one death,” Mr Ghebreyesus said.
Mr Ghebreyesus noted that the organisation previously assessed the outbreak risk as high nationally and regionally, and low globally, but has now revised it to “very high” at the national level, “high” regionally and “low” globally.
WHO said the outbreak is caused by the Bundibugyo strain of Ebola, unlike previous outbreaks driven by the Zaire strain.
The agency explained that there are currently no approved vaccines or therapeutics for the Bundibugyo virus, making containment more difficult.
WHO also noted that commonly used Ebola diagnostic tests designed for the Zaire strain do not detect the Bundibugyo strain effectively, contributing to delays in identifying the outbreak.
“There have only been two previous outbreaks of Bundibugyo, in Uganda in 2007 and DRC in 2012,” Mr Ghebreyesus said.
The organisation warned that insecurity in the provinces of Ituri and North Kivu is further complicating response efforts.
According to the WHO, intensified fighting in recent months has displaced more than 100,000 people, while about four million people in the affected areas require urgent humanitarian assistance.
The agency also said approximately 10 million people are facing acute hunger.
Mr Ghebreyesus disclosed that a hospital in Ituri was attacked on Thursday, with tents and medical supplies set on fire.
“Building trust in the affected communities is critical to a successful response,” he said.
WHO said it has deployed 22 international staff to support response operations and released $3.9 million from its Contingency Fund for Emergencies.
Meanwhile, the WHO said the hantavirus outbreak linked to passengers and crew aboard the MV Hondius cruise ship has now recorded 12 cases and three deaths.
The latest confirmed case involved a crew member who disembarked in Tenerife and was later repatriated to the Netherlands, where the individual remains in isolation.
WHO noted that no additional deaths have been reported since 2 May, when the outbreak was first reported.
The agency said more than 600 contacts across 30 countries are still being monitored, while efforts continue to trace a small number of high-risk contacts.
Countries supporting the response include Argentina, Cabo Verde, Chile, South Africa, Spain and the United Kingdom.
The Nigeria Centre for Disease Control and Prevention (NCDC) said the country has recorded no confirmed Ebola case linked to the ongoing outbreak in Central and East Africa.
The agency said the country remains on heightened alert and has strengthened surveillance at points of entry, including airports, seaports and land borders, to prevent importation of the virus.
The health body also warned against misinformation circulating on social media suggesting that Ebola cases had been detected in Nigeria, describing such claims as false and capable of causing unnecessary panic.
Following the outbreak declaration, authorities said surveillance systems at points of entry had been strengthened, while emergency response mechanisms were being reviewed to improve readiness.
The Federal Airports Authority of Nigeria (FAAN) also announced additional health screening measures and enhanced Ebola surveillance across international airports.
The measures include heightened passenger monitoring, screening protocols, and coordination with health authorities to detect and respond swiftly to suspected cases.
