A short two-minute video Bloomberg News uploaded to YouTube attempts to explain why the world doesn't already have a widely available Ebola vaccine.

(Trusting the ingredients of such a thing and whether or not you would personally take it is another matter entirely, but hold on a second.)

Liberia's president declared a state of emergency Wednesday as the World Health Organization said the death toll from the Ebola outbreak in West Africa has risen to 932.

The new figures come as Nigeria confirmed the death of a nurse of Ebola. It was the second death from the disease in Nigeria and a growing number of cases are being reported in Lagos, a megacity of some 21 million people.

The first death in Nigeria was that of Patrick Sawyer, a 40-year-old American of Liberian descent with a wife and three young daughters in Minnesota. Sawyer, who worked in Liberia, was traveling on a business flight to Nigeria when he fell ill. Nigerian authorities acknowledge they did not treat Sawyer as an Ebola patient and failed to isolate him for the first 24 hours after his arrival in Nigeria last month.

The Centers for Disease Control and Prevention on Wednesday ramped up its response to the expanding Ebola outbreak, a move that frees up hundreds of employees and signals the agency sees the health emergency as a potentially long and serious one.

The CDC's "level 1 activation" is reserved for the most serious public health emergencies, and the agency said the move was appropriate considering the outbreak's "potential to affect many lives." The CDC took a similar move in 2005 in the aftermath of Hurricane Katrina, and again in 2009 during the bird-flu threat.

The Ebola outbreak is believed to have killed 932 people in the African nations of Liberia, Sierra Leone, Nigeria and Guinea. Two American aid workers sickened by the disease were flown back to the U.S. for treatment at a medical facility in Atlanta.

The CDC is deploying additional staff to the four affected countries, and said 50 more disease-control experts should arrive there in the next 30 days. It also issued instructions to airlines that may come into contact with passengers from the affected countries designed to minimize the chance of infection.

Our time is limited, it seems, when it comes to our faltering abilities to fight infectious diseases. Evidence has suggested for some time now that bacteria are becoming immune to common antibiotics. Similarly, malaria parasites have also been developing resistance to antimalarial drugs, including a powerful combination drug introduced in the mid-1990s called artemisinin. In a new study, scientists say that "radical measures" must be taken to prevent resistance to these drugs, otherwise, countries where the disease is prevalent will face a huge setback.

The study was led by Nicholas White of Oxford University, who is also chair of the Worldwide Antimalarial Resistance Network. It found that malarial resistance to artemisinin, and the drugs it's used in combination with to fight the disease, is spreading across major parts of Southeast Asia, including Cambodia, Thailand, Vietnam, and Myanmar. "Resistance to artemisinin has not been contained, and has now emerged or spread across Southeast Asia," the researchers wrote, adding that resistance to these drugs "may well reverse the substantial gains in malaria control. New antimalarial drugs are under development but will not be available for several years."

Derived from wormwood, artemisinin has been available for centuries (ancient Chinese used it), however, it only became a widely used antimalarial after other antimalarials, chloroquine and sulfadoxine-pyrimethamine, became obsolete from resistance. Roughly 3.4 billion people are at risk of a malarial infection, which is still prevalent throughout 97 countries, according to the World Health Organization. If artemisinin continues down the path of resistance, malaria will come back to affect a growing number of people, negating any advances the health community has made.

This year's first outbreak of the hemorrhagic fever virus Ebola started in February in the West African nation of Guinea. It then began spreading to Liberia and, for the first time, to Sierra Leone and now Nigeria. With the possible spread to England in attempts to trace 30,000 people who might have been exposed, and now an American death in Nigeria and two more Americans afflicted with it here in the US, Ebola has rapidly grown into what could become a global epidemic with a potential capacity to wipe out millions.

According to recent statistics from the World Health Organization (WHO) released just last week, at least 672 people have died out of a total of 1,201 cases so far this year in West Africa. However, seven days later the number of fatalities has jumped to 887, a spike of over 200 deaths in just the last few days.

Because the incubation period may last ten days while the infected victim may not even be aware of any illness, the virus is highly contagious. Then what begins like typical flu symptoms of fever, later vomiting as the virus spreads rapidly inside the body causing people to succumb often within days of its onset. Victims literally die from internal bleeding that in the final stages can flow out of every orifice. It has the trappings of a ghastly zombie science fiction nightmare come true.

There is no standard treatment (other than isolating the infected and quarantining those at risk). Nor is there yet an official vaccine, although Reuters just announced that as early as next month the US government will commence testing an experimental Ebola vaccine on humans after positive results were found on primates. It has been reported that the National Institutes of Health (NIH) infectious disease unit and the US Food and Drug Administration (FDA) will be running vaccine trials "as quickly as possible."

The Department of Defense and Centers for Disease Control (CDC) classify the Ebola virus as a biowarfare agent. Reports of up to 90% of humans infected die within a very short time. Therefore, it is a very real, extremely potent potential weapon of mass destruction.

Charles Arntzen is the Regents' Professor and Florence Ely Nelson Presidential Chair of the Biodesign Institute at Arizona State University. Dr. Arntzen is known as a pioneer in the development of edible plant-based vaccines, and he has also been a key collaborator on what appears to be a promising new Ebola drug.

The Washington Post recently reported that:

Armed men have allegedly poisoned wells in Liberia's New Georgia in order to kill the residents under the pretext of Ebola outbreak.

The water from the wells and pumps has been used by thousands of people in the area.

At least 16 people are suspected to be dead because of well-poisoning in the Margibi community.

It is still unclear what the exact motive of the culprits was. Witnesses have reported sighting armed men introducing suspected poisonous substances using syringes.

The villagers reported the incident to the police and investigators are said to be looking into the matter.

The Minister of Internal Affairs, Mr. Morris Dukuly, has disclosed that a Liberian has died of the deadly Ebola virus in Morocco.

The Ebola virus, which has no cure, has killed at least 129 people here, and claimed more than 670 lives across the region. A top Liberian doctor working at Liberia's largest hospital died recently, and two American aid workers have fallen ill, underscoring the dangers facing those charged with bringing the outbreak under control.

Also recently, an official of the Ministry of Finance identified as Patrick Sawyer died of the disease at a Lagos hospital.

As a means of containing further spread of the disease, President Johnson-Sirleaf set up a taskforce to help in the fight of the disease and ordered the closure of the country's three land borders.

The Liberian leader also ordered that public gatherings be restricted and communities heavily affected by the Ebola outbreak be quarantined.

A Nigerian doctor has been diagnosed with Ebola nearly three weeks after a Liberian-American man with Ebola died after traveling to Lagos, Nigerian officials said Monday.

Nigerian Minister of Health Onyebuchi Chukwu told reporters that the infected physician had been treating Patrick Sawyer, a top government official in the Liberian Ministry of Finance who died of Ebola in a Nigerian hospital July 20.

Eight other people are being quarantined and three are awaiting Ebola test results, the health minister said.

Meanwhile, the World Health Organization reports an outbreak of the virus in Liberia, Sierra Leone, Guinea and Nigeria is believed to have infected 1,440 people and killed more than 826 this year.

The United States is planning to send 50 health experts to West Africa to help contain the outbreak.

Britain may be facing its first case of Ebola. A person in Wales is being monitored by health officials following a potential exposure to the virus.

Though the individual is not showing any concrete symptoms of the virus, the person has voluntarily limited their contact with others and will not be going to work, Public Health Wales (PHW) confirmed on Tuesday.

It is believed the individual may have been exposed to the virus in West Africa.

The recent outbreak of Ebola has so far killed 887 people across Guinea, Sierra Leone, Liberia, and Nigeria. Over 1,600 separate cases of the virus have been detected throughout the region.

There are currently no confirmed incidences of the virus in Wales, or in the wider United Kingdom.

"We are alert to the possibility of Ebola cases in the UK given the outbreak in Sierra Leone, Liberia, and Guinea and we remain vigilant to unexplained illness in people who have traveled from the area," PHW told the Independent on Tuesday.

Measures are currently in place to protect public health in the event of an outbreak in the region, Public Health Wales added.

The potential Ebola carrier is not currently in hospital, according to a Public Health England (PHE) spokeswoman. But if the individual develops suspicious symptoms, the person will be quarantined in a local hospital and receive medical tests to discern whether he or she has contracted the deadly disease, the spokeswoman added.
