EBOLA EPIDEMIOLOGY: Strategies for containing Ebola in West Africa

SCIENCE MAGAZINE                             Oct. 30, 2014

A study to assess the effectiveness of containment strategies, using a stochastic model of Ebola transmission between and within the general community, hospitals, and funerals, calibrated to incidence data from Liberia.

ABSTRACT

The ongoing Ebola outbreak poses an alarming risk to the countries of West Africa and beyond. To assess the effectiveness of containment strategies, we developed a stochastic model of Ebola transmission between and within the general community, hospitals, and funerals, calibrated to incidence data from Liberia. We find that a combined approach of case isolation, contact tracing with quarantine and sanitary funeral practices must be implemented with utmost urgency in order to reverse the growth of the outbreak. Under status quo intervention, our projections indicate that the Ebola outbreak will continue to spread, generating a predicted 224 (95% CI: 134 – 358) cases daily in Liberia alone by December, highlighting the need for swift application of multifaceted control interventions.

US Envoy: 'Alarming Gaps' Remain in Fighting Ebola

VOICE OF AMERICA                                                              Oct. 31, 2014

By Al Pessin

The international community must do more to fill "alarming gaps" in the fight against the Ebola epidemic, U.S. ambassador to the United Nations Samantha Power said to an audience in Brussels as she headed home from a visit to the three hardest-hit countries in West Africa.

U.S. Ambassador to the United Nations Samantha Power speaks during a lecture regarding the Ebola virus at the Residence Palace in Brussels, Oct. 30, 2014.

Power said the initial international response is making a difference, and has created what she called “the first tangible signs that the virus can and will be beaten.”

But, she said, many countries have not done enough, and urged them to not assume the job is done...

She called for more flexible planning, faster decision-making, and for support for the affected countries as they try to rebuild and expand their health care systems. Those systems were inadequate before the epidemic and have now been devastated by the deaths of hundreds of doctors and nurses.

(GENEVA)- The World Bank pledged $100 million on Thursday to help recruit more foreign health workers in the fight against Ebola, taking its funding for the three worst-hit countries to more than half a billion dollars over the past three months.

The latest tranche will go towards setting up a coordination hub to recruit, train and deploy qualified foreign health workers and support the three countries' efforts to isolate Ebola patients and bury the dead safely, the bank said.

FREETOWN, Sierra Leone--  A British Navy support ship ship has arrived in Sierra Leone to help deal with the deadly Ebola outbreak in the West African country.

Royal Fleet Auxiliary Argus is carrying food, medical equipment, three helicipeters and 32 pick-up trucks, to help keep hard-pressed Ebola treatment centres going.

Doctors, nurses and military personnel are also on board.

The BBC's Africa correspondent Andrew Harding said it would act as an offshore base for the aid effort. and described it as an "important moment".

FREETOWN, Sierra Leone --Liberia is making some progress in containing the Ebola outbreak while Sierra Leone is "in a crisis situation which is going to get worse," the top anti-Ebola officials in the two countries said.

The people of both countries must redouble efforts to stop the disease, which has infected more than 13,000 people and killed nearly 5,000, the officials said. Their assessments underscore that Ebola remains a constant threat until the outbreak is wiped out. It can appear to be on the wane, only to re-emerge in the same place or balloon elsewhere if people don't avoid touching Ebola patients or the bodies of those who succumb to the disease.

Assessing the Science of Ebola Transmission

THREE ARTICLES DESCRIBING DETAILS OF THE EBOLA VIRUS AND OTHER VIRUSES.

Advances in microscopy have allowed scientists like Sriram Subramaniam and colleagues at the National Cancer Institute to look at the workings of tiny viruses.

Maine state police dispatched to back nurse's quarantine

USA TODAY                                                                        OCT. 29, 2014
By Doug Staglin
Maine state police were stationed outside the home of Ebola nurse Kaci Hickox Wednesday as Gov. Paul LePage said he was seeking legal authority to force the "unwilling" health care workers to remain quarantined for 21 days.

The 33-year-old nurse, who has shown no symptoms of the deadly virus, arrived in Maine on Monday after being forcibly held in an isolation tent in New Jersey for three days under that state's strict new law for health care workers who have recently treated Ebola patients in West Africa.

Over Hickox's objections, Maine health officials insisted that she stay in her home in Fort Kent for 21 days until the incubation period for Ebola had passed.

"I don't plan on sticking to the guidelines," Hickox tells Today show's Matt Lauer. "I am not going to sit around and be bullied by politicians and forced to stay in my home when I am not a risk to the American public."

Low HIV and Aids rates saw west Africa ‘miss out on health investment'

THE GUARDIAN                                                                                Oct. 28, 2014

West Africa, now in the throes of a calamitous Ebola epidemic, missed out on significant health investment over the past decade or more because it had low rates of HIV, a detailed survey of the changing health of Africa and Asia reveals.

A major project called Indepth, which has looked at the causes of death of more than 110,000 people in 13 countries shows that health improved generally in those given substantial international aid to try to turn around the HIV and Aids epidemic. But west Africa, with severe poverty and low healthcare standards but relatively little HIV, did not benefit.

State Department plans to bring foreign Ebola patients to U.S.

LEAKED MEMO SAYS STATE DEPARTMENT CONSIDERING TREATING NON-AMERICAN HEALTH WORKERS BUT AN OFFICIAL SAYS DISCUSSIONS WERE SHELVED

THE WASHINGTON TIMES                         Oct. 29, 2014
By Stephen Dinan- The Washington Times - Tuesday, October 28, 2014

The State Department has quietly made plans to bring Ebola-infected doctors and medical aides to the U.S. for treatment, according to an internal department document that argued the only way to get other countries to send medical teams to West Africa is to promise that the U.S. will be the world’s medical backstop.

Some countries “are implicitly or explicitly waiting for medevac assurances” before they will agree to send their own medical teams to join U.S. and U.N. aid workers on the ground, the State Department argues in the undated four-page memo, which was reviewed by The Washington Times.... (Editor's note: Australia and Canada are among the countries.)

The inflatable tents have also been purchased for the treatment of Ebola patients by other countries on the continent, according to the Israeli company SYS Technologies, which specializes in the development of clean-air systems and mobile operating theaters. The company said the units can be constructed and shipped within two weels.

The units use a positive pressure technology to create an absolute clear and isolated environment and maintain the structure. The company has also developed an incubator-like stretcher for the safe transfer of patients to the isolation tents.
