Merck, NewLink Ebola vaccine appears safe, effective in new studies

Early-stage trials of an experimental Ebola vaccine, two in the United States and four in Africa and Europe, have found that it appears to be safe and triggered robust production of Ebola-fighting antibodies, scientists reported on Wednesday.

Since trials cannot ethically expose volunteers to Ebola, the production of antibodies is a proxy for whether vaccines could prevent or even treat the disease.

The trials all tested a vaccine called VSV-ZEBOV, which was developed at the Public Health Agency of Canada and licensed to NewLink Genetics Corp and then to Merck & Co Inc. It consists of a cattle virus called rVSV that has been engineered to carry Ebola genes, which produce proteins meant to trigger production of anti-Ebola antibodies.

According to separate teams of scientists, that is what happened, two papers in the New England Journal of Medicine reported.

App enables self-reporting of possible Ebola symptoms in Maryland

ASSOCIATED PRESS                                                                                     April 1, 2015

BALTIMORE — A Baltimore company and Maryland public health officials are announcing a smartphone and Web application for self-reporting possible Ebola symptoms.

Emocha Mobile Health Inc. said Wednesday that people returning from affected West African nations can use the app to report their temperature and any symptoms twice daily to the Department of Health and Mental Hygiene. The federal government recommends such reporting for 21 days.

The state health agency has operated a call center since October for monitoring people known to have been in affected countries. The app eventually will link to the state's database of such individuals to automate the reporting of data to Maryland and federal authorities.

Faulty modeling studies led to overstated predictions of Ebola outbreak

MEDICAL EXPRESS                                                                       MARCH 31, 2015

Frequently used approaches to understanding and forecasting emerging epidemics—including the West African Ebola outbreak—can lead to big errors that mask their own presence, according to a University of Michigan ecologist and his colleagues.

Last September, the U.S. Centers for Disease Control and Prevention estimated—based on computer modeling—that Liberia and Sierra Leone could see up to 1.4 million Ebola cases by January 2015 if the viral disease kept spreading without effective methods to contain it. Belatedly, the international community stepped up efforts to control the outbreak, and the explosive growth slowed.

"Those predictions proved to be wrong, and it was not only because of the successful intervention in West Africa," King said. "It's also because the methods people were using to make the forecasts were inappropriate."

Guinea shuts border with Sierra Leone in effort to end Ebola

ASSOCIATED PRESS by BOUBACAR DIALLO               March 30, 2015

CONKAKRY --Guinea closed its border with Sierra Leone on Monday as part of new efforts to stamp out Ebola, an official said.

... the disease remains stubbornly entrenched in Guinea more than a year after the outbreak started and authorities are now ramping up efforts to eliminate the disease.

Guinean President Alpha Conde announced this weekend that emergency measures would be "reinforced" for a 45-day period in five districts, including some along the border with Sierra Leone. The decision to close the border was made in the context of those new measures, according to Cmdr. Mamadou Alpha Barry, spokesman for the national gendarmerie.

Previously, Guinean authorities had monitored people crossing into the country for symptoms of the disease.

Sierra Leone’s 3-Day Ebola Lockdown is Over

Sierra Leone Ebola lockdown exposes hundreds of suspected cases

REUTERS                                                                                                      March 30, 015

(Scroll down for earlier story.)

FREETOWN - A three-day lockdown in Sierra Leone has exposed hundreds of potential new cases of Ebola, aiding efforts to bring to an end an epidemic that has already killed 3,000 people in the country.

Officials ordered the country's 6 million residents to stay indoors or face arrest during the period that ended late on Sunday as hundreds of health officials went door-to-door looking for hidden patients and educating residents about the virus.

Reports to authorities of sick people increased by 191 percent in Western Area, which includes the capital, during the lockdown compared with the previous weekend, said Obi Sesay of the National Ebola Response Center.

"Tests are being carried out on their blood samples, and the results will be in by Wednesday," Sesay said, adding that 173 of the patients in Freetown met an initial case definition for Ebola.

Ebola rapid diagnostic kit developed by UK scientists in Sierra Leone

Doctors says the kit, if approved by health authorities, could transform the admissions process with its capacity to deliver results within 20 minutes

It can be administered at the bedside and return its first results within 20 minutes, slashing dramatically the normal 24-hour turnaround for lab results.

THE NEW YORK TIMES  by Sheri Fink                                                                          March 29, 2015

The Liberian government recommended on Saturday that survivors of Ebola practice safe sex indefinitely, until more information can be collected on the length of time the virus might remain present in body fluids including semen. Previously, male survivors were advised to abstain from sexual intercourse or to use condoms for three months, reflecting that the active virus had been detected for up to 82 days in semen.

Police fire tear gas on crowd during Sierra Leone Ebola lockdown

REUTERS by Josephus Olu-Mammah and Umaru Fofana                                                              March 28, 2015
FREETOWN, Sierra Leone --Police fired tear gas at an angry crowd in Sierra Leone on Saturday after they threw stones at officials during a three-day national lockdown that the government hopes will accelerate the end of the Ebola epidemic, residents said.

Sierra Leone has reported nearly 12,000 Ebola cases and more than 3,000 deaths since the worst epidemic in history was detected in neighbouring Guinea a year ago. New cases have fallen sharply since a peak of more than 500 a week in December but the government says the lockdown, its second, is necessary to identify the last cases and to buck a worrying trend towards complacency.

Officials have ordered the six million residents to stay inside on pain of arrest as hundreds of health official go door-to-door looking for hidden patients and educating residents about the haemorrhagic fever.

Hundreds of people left their homes in the Devil Hole neighbourhood outside the capital to gather at a food collection point. Some residents complained they had not received food and fighting broke out until police arrived to scatter the crowd.
