Neglected Tropical Diseases in the Ebola- Affected Countries of West Africa

PLOS   EDITORIAL by Peter J. Hotez, Sabin Vaccine Institute                          June 25, 2015
While global attention in West Africa is focused on the emergence of Ebola virus infection, new information from the published literature and World Health Organization databases reveals that many other neglected tropical diseases (NTDs) are far more widespread and also require urgent attention.
Well before Ebola virus infection emerged in West Africa at the end of 2013, the three
major affected countries--Guinea, Liberia, and Sierra Leone were already known to
be highly affected by NTDs....
Today, new information from the recent literature and the World Health Organization
(WHO) Preventive Chemotherapy and Transmission (PCT) Control databases reveals that
NTDs remain widespread in Guinea, Liberia, and Sierra Leone.  An estimated

Malaria morbidity and mortality in Ebola-affected countries caused by decreased health-care capacity, and the potential effect of mitigation strategies: a modelling analysis

LANCET by Patrick G. T. Walker and others                               Volume 15, No. 7, p825–832, July 2015
The ongoing Ebola epidemic in parts of west Africa largely overwhelmed health-care systems in 2014, making adequate care for malaria impossible and threatening the gains in malaria control achieved over the past decade. We quantified this additional indirect burden of Ebola virus disease.

We estimated the number of cases and deaths from malaria in Guinea, Liberia, and Sierra Leone from Demographic and Health Surveys data for malaria prevalence and coverage of malaria interventions before the Ebola outbreak. We then removed the effect of treatment and hospital care to estimate additional cases and deaths from malaria caused by reduced health-care capacity and potential disruption of delivery of insecticide-treated bednets. We modelled the potential effect of emergency mass drug administration in affected areas on malaria cases and health-care demand....

The World Health Organisation (WHO) has assured Ghanaians that the proposed Ebola vaccine trial will not cause Ebola in the country.

WHO says it views the safety of people as paramount and would, therefore, not overlook any wrongdoing in the development of a vaccine.

 The WHO Country Representative, Dr Magda Robalo, gave the assurance at a public sensitisation forum in Accra last Thursday....

 Recently, following public agitations, the Minister of Health, Mr Alex Segbefia, called for more consultation on the proposed Ebola vaccine trial which was to be undertaken at Hohoe in the Volta Region.

Ebola showed aid delivery desperately needs an overhaul

WASHINGTON -- The Ebola epidemic exposed long-standing holes in aid delivery,  which desperately needs an overhaul before the next international emergency hits, aid experts said on Thursday.

Many of the shortcomings seen during the Haiti earthquake of slow responses and uncoordinated relief efforts were repeated during the Ebola crisis that erupted in West Africa a year ago, they said.

With Sierra Leone and Guinea continuing to report cases of the deadly virus, the international community must act urgently, said Carolyn Reynolds, external relations manager at the World Bank.

"We need to think outside the box," she said at a panel on global health preparedness held on Capitol Hill.

Ebola genetic code analysed to show evolution of worst ever outbreak

THE GUARDIAN   by Ian Sample                                                                             June 18, 2015

Scientists have analysed the genetic code of Ebola viruses from patients across west Africa and pieced together the evolution of the worst ever outbreak of the killer disease.

Experts from Public Health England at Porton Down in Britain, the World Health Organisation (WHO), and other leading labs, used DNA from 179 Ebola samples to reconstruct the spread of the virus from Guinea into surrounding countries last year.

Why Some Ebola Strains Are More Dangerous Than Others

CHEMISTRY WORLD by Christopher Barnard             June 17, 215
The virulence of Ebola virus strains appears to be innately linked to the degree of disorder in proteins that form their nucleocapsids. Computational analysis has revealed that strains responsible for the most lethal outbreaks of Ebola show significantly higher levels of intrinsic protein disorder than less virulent strains, in a discovery that could constitute a major breakthrough in understanding the pathogen’s behaviour.

With over 27,000 confirmed, probable and suspected cases and more than 11,000 fatalities worldwide, the ongoing Ebola outbreak has resulted in considerably more casualties since late 2013 than all other outbreaks combined. There are no effective treatments or vaccines against the haemorrhagic fever that evinces Ebola infection; however, strains of the virus with drastically different virulence have emerged since the first outbreak in 1976, with fatality rates ranging from 25 to 90%.

Ebola vaccines in limbo expose need for more speed in trials

REUTERS by Kate Keller and Ben Hirschler                                      June 17, 2015

LONDON --Drugmakers' plans to conduct vast clinical trials to test and hopefully validate the first Ebola vaccines have been thwarted by success in beating back the deadly epidemic in West Africa.

GlaxoSmithKline, Merck and Johnson & Johnson are struggling to recruit volunteers with enough exposure to the disease to prove whether their vaccines are doing the job and preventing infection.

The story might have been very different with just another three or four months of disease spread, underscoring the need to act more quickly to develop vaccines for emerging diseases....

Guinea, where Ebola is still infecting new victims, as "the only hope" for showing efficacy, according to Kieny and to Adrian Hill, director of the Jenner Institute at Britain's Oxford University.

The WHO is overseeing the so-called ring vaccination study in Guinea in which close contacts and family around each new case of Ebola are vaccinated -- either immediately or after a three-week delay -- to see if the shot offers protection.

Turn on the taps to defeat the next Ebola

IRIN by Jennifer Lazuta                                 June 15, 2015

DAKAR, Senegal - It is a cruel irony that many of the top doctors and nurses in Guinea, Liberia and Sierra Leone will not be around to help rebuild their health systems in the wake of Ebola, having succumbed themselves to the virus.

 For those that are, the biggest challenges are likely to be electricity, sanitation, and, most of all, water.

“How is it possible to build, or rebuild, as you may call it, a health institution or hospital without [access to] water, which serves as a major catalyst to run the facility?” asked Moses Tamba, a spokesperson for Liberia’s Ministry of Public Works. “It is not possible. You need water....”

Health Authorities Repeating Mistakes in Ebola Fight: MSF

AFP - June 13, 2015

Dakar (AFP) - Health authorities are repeating the mistakes of the past in combatting Ebola, more than a year after its onset in Guinea and Sierra Leone, the international president of Doctors Without Borders (MSF) warned.

Joanne Liu's remarks on Saturday come a day after Sierra Leone imposed a three-week daytime curfew in the last Ebola-hit areas in a bid to curb a resurgence of the deadly virus, which has killed about 3,900 people in the country.

Neighbouring Liberia was declared Ebola-free in May, but hopes that Sierra Leone and Guinea would quickly follow suit have been dashed in recent weeks.

"We are still making the same mistakes as we did in the past," said Liu.
