Weaponized Plague Is Just Another Jihadist Pipe Dream

On Aug. 28, Foreign Policy magazine released an exclusive story by Harald Doornbos and Jenan Moussa titled Found: The Islamic State's Terror Laptop of Doom. The story noted that among a cache of documents found on a computer captured from the Islamic State in Syria was a 19-page document purported to be instructions for creating a biological weapon by weaponizing plague extracted from infected animals. According to the article, the document noted: "The advantage of biological weapons is that they do not cost a lot of money, while the human casualties can be huge."
This document provides a good example of the terrorist tradecraft conundrum militant organizations often face, in which their intent outstrips their capability. While biological weapons do appear to be easy to manufacture and deploy in theory, history shows a successful biological weapons program is far harder to achieve than it may appear at first glance.
As we noted in 2009 in response to rumors that al Qaeda in the Islamic Maghreb was experimenting with the plague as well, the plague, sometimes referred to as the Black Death, is a naturally occurring disease that is caused by the bacterium Yersinia pestis. This pathogen is found in rodents and fleas that infest them and exists in many parts of the world, including the western United States. According to the U.S. Centers for Disease Control and Prevention, there are some 1,000 to 2,000 cases of plague diagnosed in humans every year, with between one and 17 of those cases occurring in the United States. It is notable, however, that according to the World Health Organization, plague does not occur naturally in Syria or Iraq, although it does in Libya and Algeria.
Y. pestis can infect humans in three ways. The bacteria cause pneumonic plague when inhaled, though pneumonic plague can also occur when plague bacteria from another form of transmission infect the lungs. Bubonic plague results when the bacteria enter through a break in the skin (such as a fleabite) and septicemic plague occurs when the bacteria multiply in the victim's blood, usually after being infected by one of the other types. In general, a fleabite is the primary form of infection, and if the infection is left untreated, it can evolve into a case of bubonic (the most common outcome) or septicemic plague.
Y. pestis is a fragile bacterium that does not last long in sunlight or after it is dried, and plague is treatable with antibiotics, which are especially effective if administered early. However, pneumonic plague can be contagious if a person inhales respiratory droplets containing the bacteria from an infected person. Such a transmission usually requires close contact with the infected individual. Merely wearing a simple surgical mask can protect a person from pneumonic plague infection.
Before we assess the Islamic State's capability and intent to create a weapon using plague, let's first look briefly at the history of plague as a weapon.
Plague has long been of interest as a weapon in biological warfare, with reports from Tatars catapulting plague-infected bodies at Genoese sailors in the City of Caffa in the Crimea in the 14th century, to Japan's efforts to drop clay pots of plague-infected fleas over Manchuria, to the Soviet weapons programs during the Cold War and perhaps beyond. While the Tatars and Japanese used the bubonic form of the plague, according to former Soviet scientist Ken Alibek, the Soviet program focused on and perfected an aerosolized form of the bacterium designed to cause pneumonic plague.
Without question, the best example of a modern non-state actor developing a biological weapons program was the Japanese Aum Shinrikyo, which in the late 1980s assembled a team of trained scientists and spent millions of dollars to develop a series of state-of-the-art biological weapons research and production laboratories.
Aum experimented with botulinum toxin, anthrax, cholera and Q fever and even tried to acquire the Ebola virus. However, despite multiple attempts to produce mass casualty attacks using botulinum toxin and anthrax from 1990 to 1993, Aum was not able to produce a virulent agent -- indeed, nobody outside of the group was even aware that the attacks happened. It was only when the group switched to producing chemical weapons, such as the nerve agent sarin and sodium cyanide gas, that it was able to conduct fatal attacks in 1995. The investigation into the chemical attacks produced the evidence of the group's extensive biological weapons program. Frankly, they could have killed far more people, with far less expense and effort, using firearms or bombs, but such conventional weapons could never produce the global apocalypse the group's leadership aspired to.
Despite the difficulties inherent in developing a biological weapons program, radical groups have not given up. It has long been known that jihadist groups such as al Qaeda have sought to develop chemical and biological weapons, believing that using such weapons is not only permissible but even an obligation. In an interview aired on ABC News in December 1998, Osama bin Laden said, "If I have indeed acquired these weapons, then this is an obligation I carried out, and I thank God for enabling me to do so." While terrorist groups have experimented with crude biological toxins such as ricin and crude chemical compounds such as sodium cyanide gas, they have not been able to parlay those experiments into viable weapons capable of creating mass casualties.
To properly understand the threat posed by the Islamic State's employing biological weapons, we must examine both the group's intent and capability. First, as noted above, the group has ample ideological justifications. Second, by design, terrorist attacks are intended to have a psychological impact far outweighing the physical damage they cause. As their name suggests, they are meant to cause terror that amplifies the actual attack. The Islamic State has a long history of conducting brutal actions intended to cause panic, and a successful biological terrorist attack would certainly create such a panic.
Clearly, if the Islamic State were able to develop effective biological weapons, it would employ them, if not against targets in the West, then against regime targets in Iraq and Syria. Indeed, in 2006 and 2007 the group's predecessor, al Qaeda in Iraq, included large quantities of chlorine in vehicle bombs in an effort to cause mass casualties against U.S. and Iraqi troops in Iraq. These weapons proved quite ineffective, and the explosives in the bombs killed more people than the chlorine. This caused the group to discontinue their use when they did not achieve the desired results.
The Islamic State would love to discover a cheap and easy way to create mass casualties, but in pursuing plague as a weapon, the group appears to have bought into some of the many common misconceptions involving biological weapons, namely, that they are easy to obtain, easy to deploy effectively, and, when used, always cause massive casualties. But as illustrated by the above-mentioned Aum Shinrikyo example, in the real world, creating an effective biological weapons program requires extensive investment, scientific know-how, and time and effort -- and they still don't always work as advertised.
Like many biological agents, there are great challenges associated with producing and employing large quantities of a virulent biological agent. Certainly, plague can be obtained from the environment in a place where it occurs naturally, such as Algeria or Libya, but taking that bacteria and producing a large quantity of it in a virulent form and then disbursing it in an efficient manner is another matter entirely. While the huge Soviet biological weapons program was able to overcome these obstacles and successfully produce an effective aerosolized plague weapon, it would be difficult for a smaller organization like the Islamic State to do so, especially since it lacks access to a large and advanced biological weapons program and the associated and necessary facilities.
In addition to the difficulty of establishing a viable biological weapons program in the Islamic State-controlled areas of Iraq and Syria, there are also some additional problems with the plot as reportedly outlined in the purported Islamic State biological warfare document. According to Foreign Policy, the document advised the attackers to "use small grenades with the virus, and throw them in closed areas like metros, soccer stadiums, or entertainment centers," and said that it is "best to do it next to the air-conditioning. It also can be used during suicide operations."
As noted above, Y. pestis is a fragile bacterium. The heat and shock of a grenade explosion would almost certainly kill most of the bacteria before it could be transmitted to a victim. Even if some of the bacteria were to survive the grenade's explosion, bubonic and septicemic plagues are not easily spread from person to person, and an attack with a small grenade device would therefore be unlikely to cause an epidemic; it would likely cause more panic than deaths.
If Islamic State attack planners could isolate a virulent strain of Y. pestis, infecting a few suicide operatives with pneumonic plague and then dispatching them to cough and sneeze on people, or attempting to release some infected fleas in a targeted area, might better serve them. But even if the group were somehow successful in infecting people, even these scenarios would not produce the type of mass casualties the Islamic State seeks since plague is readily treatable with antibiotics, making weaponized plague just another jihadist pipe dream.

U.S. Scientists See Long Fight Against Ebola
By DENISE GRADYSEPT. 12, 2014
The deadly Ebola outbreak sweeping across three countries in West Africa is likely to last 12 to 18 months more, much longer than anticipated, and could infect hundreds of thousands of people before it is brought under control, say scientists mapping its spread for the federal government.
“We hope we’re wrong,” said Bryan Lewis, an epidemiologist at the Virginia Bioinformatics Institute at Virginia Tech.
Both the time the model says it will take to control the epidemic and the number of cases it forecasts far exceed estimates by the World Health Organization, which said last month that it hoped to control the outbreak within nine months and predicted 20,000 total cases by that time. The organization is sticking by its estimates, a W.H.O. spokesman said Friday.
But researchers at various universities say that at the virus’s present rate of growth, there could easily be close to 20,000 cases in one month, not in nine. Some of the United States’ leading epidemiologists, with long experience in tracking diseases such as influenza, have been creating computer models of the Ebola epidemic at the request of the National Institutes of Health and the Defense Department.
The Centers for Disease Control and Prevention declined to comment on the projections. A spokesman, Tom Skinner, said the agency was doing its own modeling and hoped to publish the results soon. But the C.D.C. director, Dr. Thomas R. Frieden, has warned repeatedly that the epidemic is worsening, and on Sept. 2 described it as “spiraling out of control.”
While previous outbreaks have been largely confined to rural areas, the current epidemic, the largest ever, has reached densely populated, impoverished cities — including Monrovia, the capital of Liberia — gravely complicating efforts to control the spread of the disease. Alessandro Vespignani, a professor of computational sciences at Northeastern University who has been involved in the computer modeling of Ebola’s spread, said that if the case count reaches hundreds of thousands, “there will be little we can do.”
What worries public health officials most is that the epidemic has begun to grow exponentially in Liberia. In the most recent week reported, Liberia had nearly 400 new cases, almost double the number reported the week before. Another grave concern, the W.H.O. said, is “evidence of substantial underreporting of cases and deaths.” The organization reported on Friday that the number of Ebola cases as of Sept. 7 was 4,366, including 2,218 deaths.
“There has been no indication of any downturn in the epidemic in the three countries that have widespread and intense transmission,” it said, referring to Guinea, Liberia and Sierra Leone.
The scientists who produced the models cautioned that their dire predictions were based on the virus’s current uncontrolled spread and said the picture could improve if public health efforts started to work. Because conditions could change, for better or for worse, the researchers also warned that their forecasts became shakier the farther into the future they went.

Predicting Ebola’s Future Toll
Assuming current infection rates continue, a new model estimates there could be 20,000 Ebola cases by mid-October. The model’s estimate would nearly triple under deteriorating conditions and an increasing infection rate.

Dr. Lewis, the Virginia Tech epidemiologist, said that a group of scientists collaborating on Ebola modeling as part of an N.I.H.-sponsored project called Midas, short for Models of Infectious Disease Agent Study, had come to a consensus on the projected 12- to 18-month duration and very high case count.
Another Midas participant, Jeffrey L. Shaman, an associate professor of environmental health sciences at the Columbia University Mailman School of Public Health, agreed.
“Ebola has a simple trajectory because it’s growing exponentially,” Dr. Shaman said.
Lone Simonsen, a research professor of global health at George Washington University who was not involved in the modeling, said the W.H.O. estimates seemed conservative and the higher projections more reasonable.
“The final death toll may be far higher than any of those estimates unless an effective vaccine or therapy becomes available on a large scale or many more hospital beds are supplied,” she said in an email.

Dr. Vespignani said that the W.H.O. figures would be reasonable if there were an effective campaign to stop the epidemic now, but that there is not.
The modeling estimates are based on the observed growth rate of cases and on factors like how many people each patient infects. The researchers use the past data to make projections. They can test their methods by, for instance, taking the figures from June, plugging them into the model to predict the number of cases in July, and then comparing the results with what actually happened in July.
Dr. Shaman’s research team created a model that estimated the number of cases through Oct. 12, with different predictions based on whether control of the epidemic stays about the same, improves or gets worse. If control stays the same, according to the model, the case count by Oct. 12 will be 18,406. If control improves, it will be 7,861. If control worsens, it will soar to 54,895.
Before this epidemic, the largest Ebola outbreak was in Uganda from 2000 to 2001, and it involved only 425 cases. Scientists say the current epidemic surged out of control because it began near the borders of three countries where people traveled a lot, and they carried the disease to densely populated city slums. In addition, the weak health systems in these poor countries were not equipped to handle the disease, and much of the international response has been slow and disorganized.
But questions have also been raised about whether there could be something different about this strain of Ebola that makes it more contagious than previous ones.
Researchers are doubtful, but Thomas W. Geisbert, an Ebola expert at the University of Texas Medical Branch in Galveston, said it was important to keep an open mind about the possibility. During vaccine tests expected to start next month in monkeys, he said, he and his colleagues will monitor infected animals to see if they develop unusually high virus levels early in the disease that might amplify its infectiousness.
Some scientists have also suggested that as the outbreak continues and the virus spreads from person to person, it will have more opportunities to mutate and perhaps become even more dangerous or contagious. But Stuart T. Nichol, chief of the C.D.C.’s Viral Special Pathogens Branch, said that so far, researchers monitoring the mutations had seen no such changes.

The US is woefully unprepared for receiving Ebola patients on routine flights from Africa. All of NY city hospitals are preparing for such cases, but the readiness is not great. Hospitals and emergency departments are not equipped for handling of such patients. I can imagine the panic that will occur, if a case is diagnosed at any of the city hospitals. The hospital might even empty!..causing huge financial losses...and if the virus becomes airborne...the panic will be complete. We also have our southern border to think off...what with the declaration of war by Obummer.

Obama Plans Major Ebola Offensive
More Doctors, Supplies and Portable Hospitals Planned for West Africa
By Carol E. Lee and Betsy McKay

WASHINGTON—President Barack Obama plans to dramatically boost the U.S. effort to mitigate the Ebola outbreak in West Africa, including greater involvement of the U.S. military, people familiar with the proposal said.
Mr. Obama is expected to detail the plan during a visit Tuesday to the Centers for Disease Control and Prevention in Atlanta, these people said. Among the possible moves: sending additional portable hospitals, doctors and health-care experts, providing medical supplies and conducting training for health workers in Liberia and other countries.
Mr. Obama also is expected to urge Congress to approve the request he made last week for an additional $88 million to fund his proposal.
"There's a lot that we've been putting toward this, but it is not sufficient," Lisa Monaco, Mr. Obama's counterterrorism adviser, said in an interview Sunday. "So the president has directed a more scaled-up response and that's what you're going to hear more about on Tuesday."
The strategy has four components: control the outbreak at its source in West Africa; build competence in the region's public-health system, particularly in Liberia; bolster the capacity of local officials through enhanced training for health-care providers; and increase support from international organizations, such as the United Nations and the World Health Organization.
Mr. Obama plans to use a gathering of world leaders at the United Nations next week to seek commitments of funds, materials and health workers for a more robust international response.
The Ebola outbreak has infected at least 4,784 people as of Sept. 12, with 2,400 of them dying—a jump from 3,707 cases and 1,848 deaths as of Aug. 31. The true toll probably is much higher, the WHO says.
The Obama administration has grown increasingly concerned in the last two weeks, as infectious-disease and public-health experts warned that the global response is inadequate to subdue an epidemic that has spiraled out of control, and that it threatens the U.S. and other countries, not just West Africa.
Mr. Obama ordered a bolder U.S. effort about two weeks ago after CDC Director Tom Frieden briefed the White House on his findings from a trip to West Africa, senior administration officials said. Dr. Frieden said publicly on Sept. 2 that he saw dozens of patients lying on the ground in an Ebola treatment center because there weren't enough beds. "I could not possibly overstate the need for an urgent response," he said.
Mr. Obama's plan is a reaction to concern that the epidemic could significantly grow in West Africa, particularly in urban areas. Administration officials stress that the chances of an outbreak in the U.S. are low.
One rising concern among officials is the possibility that the virus could mutate in a way that would make it more dangerous.
The more the virus spreads from one human to another, the more opportunities it has to mutate, virologists say. While not all scientists agree that significant mutations that would change the way the virus is transmitted are likely, one recent study of virus samples over three weeks in Sierra Leone found many mutations.
While an administration official said a dangerous mutation of the virus is unlikely at this stage, "that is a concern that is motivating us to, and the international community more broadly, to get involved even more so now to bring this under control."
The CDC has at least 105 staff in West Africa—one of the largest deployments in CDC history—tracking down people who have been exposed to Ebola, conducting education campaigns, and other tasks. The government has spent more than $100 million on the outbreak since March, and recently committed an additional $75 million in funding, according to a U.S. Agency for International Development official. The money is used to deploy staff and deliver supplies, such as chlorine and water, as well as hospital beds.
The U.S. military has sent eight service members to the region, including doctors, a logistician and medical specialists. It also said it would send a 25-bed portable hospital unit to Liberia to help care for health workers, but it isn't planning to staff it. Many public-health and infectious disease experts have called for a greater U.S. military role, which is highly valued in humanitarian crises for its ability to command and control large operations, as well as its logistics expertise.
U.S. defense officials have ruled out sending hospital ships or the big-deck amphibious ships that frequently respond to humanitarian disasters. One official said if the virus got aboard one of those ships, it could quickly spread and would be difficult to stamp out.
These experts say that is what is needed in West Africa, because the governments of the three most affected countries—Liberia, Sierra Leone and Guinea —have been overwhelmed and their health-care systems have all but crumbled. The crisis also has become too large for aid organizations and health ministries to handle alone, they say. The current response, involving several local and international agencies and organizations, also lacks coordination.
The military could be used to direct supplies, set up tent hospitals, and tap the masses of medical personnel that are needed globally to get the sick into isolation and treatment, so they stop spreading the disease to others and improve their chances of recovery. Now, there are so few hospital beds that many are having to suffer through the disease at home, where they risk spreading it to loved ones.
And while hundreds of millions of dollars in aid have recently been pledged, under current circumstances it won't arrive in West Africa for weeks - by which time thousands more will be infected and dead.
Mr. Obama hopes to begin to turn the situation around with the rollout of his new strategy, administration officials said.
"We think these measures, this enhanced response, will help us bring this under control," an administration official said Sunday. "The military has unique capabilities in terms of logistical capacities, in terms of manpower, in terms of operating in austere environments."
The administration faces formidable challenges in carrying out any response plan. Not only is the virus now spreading fast, but health workers and epidemiologists have been physically attacked or run out of villages by angry or frightened locals. Some locals argue that Ebola is a bioweapon seeded by the West.
Joanne Liu, international president of Doctors Without Borders, called earlier this month for governments to send in their militaries. The aid organization has led treatment efforts since the beginning of the Ebola outbreak and has been warning for months that a bigger response is needed.
"Without this deployment, we will never get the epidemic under control," she said.

C.D.C.’s Worst-Case Ebola Scenario: 1.4 Million Cases in 4 Months
Yet another set of ominous projections about the Ebola epidemic in West Africa was released Tuesday, in a report from the Centers for Disease Control and Prevention that gave worst- and best-case estimates for Liberia and Sierra Leone based on computer modeling.
In the worst-case scenario, Liberia and Sierra Leone could have 21,000 cases of Ebola by Sept. 30 and 1.4 million cases by Jan. 20 if the disease keeps following its current trajectory, without effective methods to contain it. These figures take into account the fact that many cases go undetected, and estimate that there are actually 2.5 times as many as reported.
The report does not include figures for Guinea because case counts there have gone up and down in ways that cannot be reliably modeled.
In the best-case model — which assumes that the dead are buried safely and that 70 percent of patients are treated in settings that reduce the risk of transmission — the epidemic in both countries would be “almost ended” by Jan. 20, the report said. It showed the proportion of patients now in such settings as about 18 percent in Liberia and 40 percent in Sierra Leone.

That depends if it is "helped" along by means other than nature and people's will (or lack thereof), to control the flow of people entering and exiting countries. Even then, with all of the ill will in place these days, regardless of side, Ebola will run its course. It matters not. Enjoy the moment.
We all die. The second one accepts that, only then are they capable of living.

Feds Underestimating How Easy It Is to Get Ebola
A nurse from one of the best health care systems in the world has contracted Ebola. The nurse cared for Thomas Eric Duncan, the man who traveled to Dallas from Liberia with the disease, and checked herself into her hospital's emergency room Oct. 12. This story challenges the Obama administration's narrative. In a September video message, Barack Obama told the people of Liberia it was safe enough to sit on the bus next to a person infected with the disease and still not contract Ebola. Cue the CDC, which issued a travel warning for the country, telling travelers to "avoid unnecessary travel." Now, doctors are saying it may be easier to contract the disease than previously assumed. Dr. Dennis Maki, an infectious diseases specialist at the University of Wisconsin-Madison, said, "Some of the garb the health worker takes off might brush against a surface and contaminate it. New data suggest that even tiny droplets of a patient's body fluids can contain the virus." The 3,000 American soldiers fighting Ebola in Liberia are in greater danger than Obama lets on.
