GENEVA: The Ebola outbreak in the Democratic Republic of Congo does not yet merit being labelled an emergency of "international concern," the World Health Organization (WHO) said Friday.
"It was the view of the committee that the conditions for a Public Health Emergency of International Concern have not currently been met," WHO said in a statement after a meeting of its International Health Regulations Emergency Committee.
The statement added that "the response by the government of the Democratic Republic of Congo, WHO and partners has been rapid and comprehensive."
The Kinshasa government announced the outbreak of the deadly virus in northwestern Equateur province on May 8.
To date, there are 45 suspected, probable or confirmed cases and 25 people have died.
In the WHO's parlance, "a public health emergency of international concern" is an "extraordinary event" in which a disease may spread across borders and requires a vigorous international response.
"This definition implies a situation that: is serious, unusual or unexpected; carries implications for public health beyond the affected State's national border; and may require immediate international action," the WHO says on its website.
The agency first invoked the emergency mechanism in 2009 when a new strain of influenza, so-called H1N1 swine flu, emerged.
It was declared twice in 2014, when polio re-emerged after the disease was nearly eradicated and after an Ebola epidemic struck three West African countries; and in 2016, in response to an outbreak of the Zika virus.
Once the emergency is declared, the WHO plays a coordinating role.
It advises countries that are affected on how to contain the disease, including measures on health surveillance and trade and travel guidelines, and helps to pool scientific data.
Invoking the measure also helps to mobilise funding and support on the ground.
While holding off the official emergency declaration, the committee underscored that the decision can be revisited "if the outbreak expands significantly, or if there is international spread."
It is also noted that "the risk of international spread is particularly high" given the confirmation of a case in Equateur's capital Mbandaka, a key transit point on the Congo River.
Separately, WHO Director-General Tedros Adhanom Ghebreyesus told reporters that health workers planned to start Ebola vaccinations on Sunday in Mbandaka and in the remote, rural Bikoro area where the outbreak began.
The UN agency expects to have 7,500 doses of the new experimental vaccine dubbed rVSV-ZEBOV on the ground by the weekend.
The initial target group of people to be vaccinated is between 8,000 to 10,000 people.
That includes health workers, other frontline responders like those tasked with burying Ebola victims, along with 100 to 150 contacts of each Ebola patient.
Vaccine maker Merck has said it has 300,000 doses ready for the UN's use free of charge.
atic Republic of the Congo has a high risk of spreading internally, the World Health Organization warned on Friday (May 18) ahead of a meeting on whether to declare it an event of international concern.
In a statement, the UN agency said WHO Director General Tedros Adhanom Ghebreyesus would convene an emergency committee to discuss the matter.
He is due to speak to the media later on Friday.
The fresh Ebola outbreak, publicly declared on May 8 with 23 deaths so far, was first reported in a rural part of Equateur Province in the vast country's northwest but has now spread to the city of Mbandaka.
Mbandaka's population has been variously estimated at between 700,000 and 1.2 million.
Peter Salama, in charge of emergency response at the WHO, has said the spread to a city complicated the fight against Ebola, which depends on identifying and isolating suspected cases.
The city is on the banks of the Congo River which connects to the capital Kinshaha, hundreds of kilometres to the south, and also to surrounding countries, increasing the risk of a national and regional outbreak, according to WHO officials.
Ebola is lethal and highly contagious, which makes it difficult to contain - especially in urban environments where people are mobile and come into more contact with others.
Lacking an arsenal of drugs to treat the virus, doctors isolate patients and trace people who have been in contact with them.
The WHO revised its assessment of the risk of spread of the epidemic to "very high" at the national level and "high" for neighbouring countries.
Globally the risk of the outbreak spreading is classified as "low".
The current outbreak involves the same strain of the virus that hit three West African countries in 2013-15 and sparked an international panic.
It went on to kill more than 11,300 people, in the deadliest ever Ebola epidemic.
The WHO was fiercely criticised over its handling of the 2013 outbreak and has pledged to improve emergency response.
There is no licensed drug to treat or prevent Ebola, although an experimental vaccine arrived in the DRC on Wednesday and has been cleared for use by the Kinshasa government.
