Ebola virus disease update - west Africa

Disease outbreak news
22 August 2014

Epidemiology and surveillance

Between 19 and 20 August 2014, a total of 142 new cases of Ebola virus disease (laboratory-confirmed, probable, and suspect cases) as well as 77 deaths were reported from Guinea, Liberia, Nigeria, and Sierra Leone.

Health sector response

Questions have been received in WHO Headquarters about the original proposed budget for the response and the new draft budget, which is being reviewed by partners. The increase in needed resources is based on improved data and understanding of the situation on the ground in the affected countries. The new estimation of costs is derived using a unit-cost model, built for the most intense transmission areas and reflects the average operational costs based on the current situation in the affected countries. The major assumptions for the cost estimates will be announced towards the end of next week.

WHO continues to receive reports of rumoured or suspected cases from countries around the world and systematic verification of these cases is ongoing. Countries are encouraged to continue engaging in active surveillance and preparedness activities. As of today, no new cases have been confirmed outside of Guinea, Liberia, Nigeria, or Sierra Leone.

WHO does not recommend any travel or trade restrictions be applied except in cases where individuals have been confirmed or are suspected of being infected with EVD or where individuals have had contact with cases of EVD. (Contacts do not include properly-protected health-care workers and laboratory staff.) Temporary recommendations from the Emergency Committee with regard to actions to be taken by countries can be found at:

Ebola death toll rises to 1,427: WHO

Geneva (AFP) - The death toll from the Ebola outbreak sweeping through west African countries has risen to 1,427 out of more than 2,600 cases, the World Health Organization said Friday.

The latest tally, which counts the number of victims from March when the deadly disease first reared its head to August 20, found that 77 people had succumbed to the virus on Tuesday and Wednesday. The previous death toll was 1,350.

Liberia remains the worst-affected country with 624 deaths. Guinea has seen 406 people die while in Sierra Leone, 392 have succumbed to the haemorrhagic fever.

Nigeria, meanwhile, had seen five people pass away by August 20.

The latest outbreak of the disease, first identified in 1976 in what was then Zaire but is now DR Congo, is the worst-ever and countries affected are struggling to contain the spread.

Neighbours in the region and countries further afield are growing increasingly concerned over the mounting death toll, and many have stopped flights to the Ebola zone and closed land borders.

As Ebola outbreak grows, WHO notes case-count difficulties
Filed Under: Ebola; VHF
Robert Roos | News Editor | CIDRAP News | Aug 22, 2014

As West Africa's Ebola toll climbed by another 142 cases and 77 deaths today, the World Health Organization (WHO) conceded that the size of the epidemic has been underestimated and cited a list of reasons for that, from concealment and denial of cases to the closing of treatment centers and clinics.

Also today, the WHO's Keiji Fukuda, MD, MPH, speaking at a press conference in Monrovia, Liberia, estimated it will take 6 to 9 months to bring the outbreak under control. He and a United Nations (UN) official promised to scale up WHO support for the Ebola-stricken countries.

Death toll tops 1,400
With the latest cases, reported on Aug 19 and 20, the WHO's Ebola virus disease (EVD) count reached 2,615, including 1,427 deaths. The numbers include confirmed, probable, and suspected cases.

Liberia accounted for most of the increase, with 110 new cases and 48 deaths, for a total of 1,082 cases and 624 fatalities, the WHO reported. Guinea cited 28 cases and 10 deaths, raising its totals to 607 and 406, while 3 new cases and 18 deaths in Sierra Leone raised the country's count to 910 cases and 392 deaths.

A report from Liberia's Ministry of Health and Social Welfare said today that EVD has hit 117 healthcare workers in the country, killing 63 of them.

The WHO report showed just one new case and one death in Nigeria, for a total there of 16 illnesses and 5 deaths.

Nigerian cases spark concern
Meanwhile, the media today reported two newly confirmed cases in Nigeria. A Reuters story said cases were confirmed in the spouses of a man and a woman who died of the disease after helping to care for the country's first Ebola case-patient, Patrick Sawyer, who died of EVD after flying to Nigeria from Liberia in July.

The story called the two new cases "an alarming development," because the patients are outside the group of caregivers who had direct contact with Sawyer. On Aug 19 the WHO said the 12 confirmed cases in Nigeria at that point all involved individuals who had contact with Sawyer.

The Reuters story said the new illnesses raise Nigeria's tally of confirmed cases to 14. Today's WHO update says that 12 of the 16 cases in Nigeria have been confirmed. Of the 14 confirmed cases, 5 patients have died, 5 have recovered, and 4 are still being treated, according to Reuters.

The WHO noted that it continues to hear of rumored and suspected Ebola cases around the world and that "systematic verification" of them is ongoing. No new EVD cases have been confirmed outside Guinea, Liberia, Sierra Leone, and Nigeria.

In that vein, California officials announced late yesterday that a hospital patient in Sacramento tested negative for the disease. The patient had an illness that raised suspicion of EVD, but he or she was regarded as low risk on the basis of history and symptoms, officials said 2 days ago.

The US Centers for Disease Control and Prevention (CDC) tested a sample from the patient, with negative results, the California Department of Public Health said in a statement. The agency gave no details about the patient or his or her illness.

Why the epidemic has been underestimated
In a separate statement today, the WHO acknowledged that the scale of the Ebola epidemic has been underestimated and listed a number of factors that have made it hard to get an accurate assessment. The agency, which declared the epidemic an international public health emergency on Aug 8, has been accused of responding too slowly to the epidemic.

Some of the items the agency listed are not new. For example, it said many families hide sick loved ones at home, believing they can't be helped and will be more comfortable dying at home. Other families deny that a person has Ebola and fear that care in an isolation ward will lead to infection and death.

Other factors cited by the WHO:

Many treatment centers and general clinics have closed, as fear keeps patients away and causes staff members to flee
"In rural villages, corpses are buried without notifying health officials and with no investigation of the cause of death."
There are many villages with rumors of Ebola cases and deaths, but they can't be investigated because of community resistance or a lack of personnel vehicles. The WHO referred to these as "shadow zones."
The WHO also said that in parts of Liberia, newly opened treatment facilities have been immediately flooded with patients, many of whom were not previously identified. "This phenomenon strongly suggests the existence of an invisible caseload of patients who are not being detected by the surveillance system."

For example, a 20-bed Ebola treatment center in Monrovia opened last week and was immediately overwhelmed with more than 70 patients, the agency said.

WHO, UN promise more help
At the Monrovia press conference today, Fukuda of the WHO and David Nabarro, MD, of the UN sought to provide reassurance and promised more aid to West Africa. The two were wrapping up the first leg of a visit to all the affected West African countries, according to a UN statement.

Nabarro, senior UN System Coordinator for Ebola, told reporters at the end of his 2-day visit that more health workers will be brought to the country to deal with the outbreak, saying, "The United Nations is looking at ways to radically scale up support to fight Ebola," according to the UN statement.

The two officials promised that the WHO will provide 500 more treatment beds for Ebola patients in Monrovia within the next 6 weeks, according to a USA Today story today.

Fukuda, the WHO's assistant director-general for health security and environment, told reporters, "This is not a hopeless situation," the UN statement said. But he estimated it will take 6 to 9 months to tame the epidemic, according to USA Today. "We expect several months of very hard work," he said.

The two officials also said they would be increasing efforts to provide other medical care to Liberians and to support the nation's economy, the newspaper reported.

At the same press conference, Karin Landgren, special representative of the UN secretary-general and coordinator of UN operations in Liberia, said that UN peacekeepers were not involved in quarantining people because of Ebola, according to the UN statement.

CDC chief to visit West Africa
In other developments, the Associated Press (AP) reported that CDC Director Tom Frieden, MD, MPH, plans to visit West Africa to get a firsthand look at the Ebola situation. He will visit Liberia, Sierra Leone, and Guinea next week.

Frieden wants to meet African and international health leaders fighting the epidemic and to hear what help they need, the story said. He also plans to visit hospitals treating Ebola patients.
