WHO declares Ebola outbreak an international public health emergency

The World Health Organization has declared the Ebola outbreak in West Africa to be an international public health emergency that requires an extraordinary response to stop its spread.

It is the largest and longest outbreak ever recorded of Ebola, which has a death rate of about 50 per cent and has so far killed at least 932 people.

"Countries affected to date simply do not have the capacity to manage an outbreak of this size and complexity on their own," WHO chief, Dr. Margaret Chan, said at a news conference in Geneva. "I urge the international community to provide this support on the most urgent basis possible."

"Statements won't save lives," said Dr. Bart Janssens, director of operations for Doctors Without Borders. "For weeks, (we) have been repeating that a massive medical, epidemiological and public health response is desperately needed ... Lives are being lost because the response is too slow."

In the United States, the Centers for Disease Control and Prevention have already elevated their Ebola response to the highest level and have recommended against travelling to West Africa. On Thursday, CDC director Dr. Tom Frieden told a Congressional hearing that the current outbreak is set to sicken more people than all previous outbreaks of the disease combined.

What is Ebola?

Ebola viral disease is a highly infectious illness with fatality rates up to 90 percent, according to the U.N. World Health Organization. Symptoms initially include a sudden fever as well as joint and muscle aches and then typically progress to vomiting, diarrhea and, in some cases, internal and external bleeding — you can see a full, grim description of symptoms compiled by the Centers for Disease Control and Prevention (CDC) here.

The virus spreads through contact with bodily fluids of someone who is infected. Reports of human infections usually first emerge in remote areas that are in proximity to tropical rain forests, where humans can come into contact with animals such as chimpanzees, gorillas and forest antelope. The consumption of bush meat is often a precursor to such outbreaks. The WHO says fruit bats are probably the natural host for the virus.

WHO launches $100 million plan as Ebola death toll tops 700

The World Health Organization is launching a $100 million response plan to combat an "unprecedented" outbreak of Ebola in West Africa that has killed 729 people out of 1,323 infected since February.

Ebola epidemic unlikely to spread beyond Africa

The recent, deadliest outbreak ever of Ebola, the killer virus that causes internal and external hemorrhaging, is raising new concerns about the disease's spread.

Doctors Without Borders, the only aid organization that is treating infected people in West Africa, says, "The scale of the current Ebola epidemic is unprecedented in terms of geographical distribution, people infected and deaths."

According to the World Health Organization...

Ebola victims quarantined in Guinea

 — Health workers in protective hazmat suits treated patients in quarantine centers on Tuesday in a remote corner of Guinea where Ebola has killed at least 60 people in West Africa's first outbreak of the deadly virus in two decades.

Seven patients are being hospitalized at one isolation ward in Gueckedou in southern Guinea, while two others are being treated elsewhere, said Doctors Without Borders. The aid group said it is sending mobile teams into the surrounding countryside in search of people who may have been exposed since the first cases emerged last week.

Ebola Virus Suspected to Have Spread From Guinea to Liberia

Africa’s biggest Ebola outbreak in seven years has probably spread from Guinea to neighboring Liberia and also threatens Sierra Leone.

Five people are suspected to have died from the disease in Lofa county in northern Liberia, Bernice Dahn, Liberia’s chief medical officer, said at a briefing yesterday. At least 86 cases and 59 deaths have been recorded across Guinea, the west African country’s health ministry said. The capital, Conakry, hasn’t been affected, government spokesman Albert Damantang Camara said.

Air Transportation Data Helps Identify, Predict Pandemics

submitted by Luis Kun

homelandsecuritynewswire.com - December 13, 2013

Computational model demonstrates how disease spreads in a highly connected world. The computational work has led to a new mathematical theory for understanding the global spread of epidemics. The resulting insights could not only help identify an outbreak’s origin but could also significantly improve the ability to forecast the global pathways through which a disease might spread. . .

. . . Their study is published today (13 December) in the journal Science.

Disease: The Next Big One

BOZEMAN, Montana — Grim prognostications of pestilence are as old as the Book of Revelation, but they have not gone out of style or been rendered moot. Plague is a tribulation that science, technology and social engineering haven’t fixed. In the mid-1960s, some public health officials imagined that antibiotics and other modern therapies would enable us to “close the book” on infectious diseases and so make it possible to focus on noncommunicable afflictions, like heart attack, diabetes and stroke. But that optimism was mistaken...

Astrid Joosten was a 41-year-old Dutch woman who, in June 2008, went to Uganda with her husband. At home in Noord-Brabant, she worked as a business analyst. Both she and her husband, Jaap Taal, a financial manager, enjoyed annual adventures, especially to Africa. The journey in 2008, booked through an adventure-travel outfitter, took them to the Bwindi Impenetrable Forest, home to mountain gorillas.
