The UN World Health Organization (WHO) said that standard tests used in mobile and other laboratories need 2 to 6 hours to test for Ebola and cost around $100, but these requirements are difficult to meet in resource-constrained West African settings, thus severely limiting testing capacity.

“Efforts to contain the Ebola outbreaks in West Africa are currently hampered by cumbersome, slow, and complex diagnostic tests that imposed a number of additional logistical challenges, including requirements for a high level of laboratory biosafety and staff expertise in using sophisticated machines,” WHO spokeswoman Fadela Chaib told reporters in Geneva.

Anthony Banbury, the head of the UN Mission for Ebola Emergency Response (UNMEER) in New York to brief Member States this week, told the UN News Centre that he is “deeply concerned that the true numbers of people affected by the virus, dying of it, are higher than the numbers being reported.”

According to WHO statistics as of a week ago, there are more than 13,000 reported Ebola cases in eight countries since the outbreak began, with nearly 5,000 reported deaths.

“The number one priority is to stop Ebola as fast as possible,” Mr. Banbury said. “It’s all about stopping the disease, reducing transmissions, ending the crisis, protecting the communities, avoiding future deaths.”

If the world is going to effectively tackle the Ebola crisis, he said, “we can’t just be chasing it, we have to get ahead of the virus.”

The response needed is more of what the international community can provide, Mr. Banbury continued, citing the expertise required on myriad fronts, ranging from communications, medical, construction to engineering needs, as well as resource intensive needs such as treatment and care facilities, and the staff, supplies, logistics support for them.

“UNMEER is working very, very hard to bring greater capability on the ground so that we can bring this crisis to an end as quickly as possible,” he said.

Mr. Banbury also said it was “heart-breaking” when survivors of the disease are not welcomed back to their community when they’re fully healthy.

“So we have a long, hard fight ahead of us, but we’re headed in the right direction, he said.

The UN World Food Programme (WFP), meanwhile, reported that it has reached its target of 1.3 million people in the three Ebola affected countries – Guinea, Sierra Leone and Liberia.

WFP said it is now reviewing its requirements to broaden its response to address the food security and nutrition challenges of Ebola-affected communities based on the latest available assessments.

The UN Children’s Fund (UNICEF) reported that in Sierra Leone, the first nine community care centres has now been completed, and welcomed them as “critical elements in taking the fight against Ebola into the heart of communities, where the agency believes the battle against the virus would be won.”

UNICEF also reported that in Sierra Leone, its social mobilization work has put out 200,000 posters, 400,000 factsheets and sent some 1.5 million text messages.

Dr. Peter Salama, UNICEF's Global Emergency Coordinator for Ebola, said today that “UNICEF's focus is to support communities to protect themselves and to be able to access basic healthcare if any of their members contract Ebola.”
