Should Hospitals Be Considered a Significant Target Of Terror?

Many social scientists referred to guerrilla warfare as the “weapon of the weak” and terrorism as the “weapon of the weakest,” using violence to generate fear, and thereby to achieve their political goals, when direct military victory is not possible. Today terrorists usually prefer to avoid attacking heavily defended “hard targets” such as military installations. Instead they often look to lightly protected targets, such as civilian infrastructure, and mass transportation targets that will generate a higher number of casualties and more media attention. Therefore, we should be aware of the potential for attacks. Hospitals in particular can be added to the list lightly or under-defended civilian “soft targets.” They are important symbols of our society and an attack on one would further undermine the perception of the ability of the government to protect its citizens. Be aware that this is not a new concept; periodic intelligence reports raise concerns that terrorists have contemplated carrying out such attacks here and have plotted to do so:

  • In November 2002 the FBI issued an alert to hospitals in San Francisco, Houston, Chicago and Washington, D.C. warning of a vague, un-corroborated terrorist threat.
  • In August 2004 the FBI and DHS issued a nationwide terrorism bulletin warning that al-Qaeda may attempt to attack VA Hospitals throughout the U.S.
  • In November 2005, Police in London arrested two suspected terrorists accused of plotting a bomb attack.  One of the suspected terrorists was found to have a piece of paper with the words in Arabic, “Hospital = Target.”
  • In April 2005 the FBI and DHS investigate incidents of imposters posing as hospital accreditation surveyors, prompting the Joint Commission on Accreditation of Healthcare Organizations (JCAHO) to send a security alert to hospitals.

Consider that terrorism today is transnational and decentralized. Al-Qaeda now is a network of terrorist groups scattered all over the world, with a presence in practically every country. The core group primarily provides ideological guidance to these semi-autonomous cells. As a result now we see different people, different groups in different parts of the world, copying the “modus operandi” used by al-Qaeda linked groups of attacking vulnerable civilian targets with no warning. These kinds of attacks have become commonplace throughout the Middle East and South Asia, and have become increasingly routine in parts of Southeast Asia, Russia and Africa. Consider the scenario of an attack on hospitals, shopping malls, sports arenas, hotels, restaurants, bars, nightclubs, movie theaters, housing complexes and other “soft” targets, that remain relatively unprotected and in reality, unless there is an adjustment in our free and open society there is precious little that can be done to prevent them.

Bird Flu Research Details To Be Released

February 23, 2012 in Al Qaeda, America, Bio Terror, Emergency Medicine, Hazards, Terrorism

Despite fear that terrorists could the information to start epidemics, the World Health Organization (WHO) recently announced they would release the “full details” of experiments done last year by research teams, at Erasmus Medical Centre, Rotterdam, in the Netherlands, and at the University of Wisconsin-Madison on the virus known as H5N1, that made the deadly bird flu virus more contagious.

Scientists around the world have been divided on the subject, and there has been a moratorium on the research and its publication once news of the experiments was known. Some urged that the results be published in full; while others say the research is so dangerous that it should never even have been done, much less published. But bio-security experts fear mutated forms of the virus that the researchers created could escape or fall into the wrong hands and be used to spark a pandemic worse than the 1918/19 outbreak of Spanish flu that killed as many as 40-million people. But on the other hand, the Unites States representative to the organization, Dr. Anthony Fauci, the director of the National Institute of Allergy and Infectious Diseases, said that any theoretical risk of the virus being used by terrorists is far outweighed by the ”real and present danger” of similar flu viruses in the wild

Remember that biological warfare, also known as germ warfare, is the use of any organism (bacteria, virus or other disease-causing organism) or toxin found in nature, as a weapon of war. It is meant to incapacitate or kill an adversary. The level of damage depends primarily on the biological agent’s transmissibility, lethality and susceptibility to countermeasures.

Be aware that H5N1 is a highly contagious deadly strain of bird flu. It is considered so dangerous it could potentially lead to a global pandemic. The virus has killed about 60 per cent of those it has infected, making it one of the most lethal known forms of influenza in modern history.  Until recently it was thought the virus could be transmitted between humans only through close physical contact, but the Netherlands team, led by virologist Ron Fouchier have been able to mutate a deadly strain of bird flu in a laboratory, so that it can be transmitted through the air with the potential to infect and kill millions of people.  Consider that al-Qaeda’s arm in Yemen was said to be actively recruiting specialists in many forms of terror and they had even openly discussed deploying deadly poisons in an article titled “Tips for Our Brothers in the United States of America,” in its online English-language journal, “Inspire.”

Sprinklers For The Eisenhower Tunnel

January 18, 2012 in 2012, Emergency, Emergency Medicine, Firefighter, First Responder, Hazards, Homeland Security, Law Enforcement, Security

The current infrastructure of the United States includes approximately 400-highway tunnels in 35 states and thousands of miles of mass transportation (rail) tunnels. Concerns about fire safety in these tunnels existed long before terrorism exposed their vulnerability, though. These underground fires, occurring in road or railway tunnels, as well as accidents and other issues create extraordinary challenges for firefighters and emergency personnel. One of the most challenging scenarios for a firefighter is battling a blaze deep in the constricted bowels of an underground tunnel, where a fire can heat the tunnel to as much as 1500 degrees Fahrenheit.

Consider the catastrophic consequences of tunnel fires, not only resulting in loss of life and severe property damage, but also in a profound lack of confidence from the public regarding the use of such systems. In an effort to be proactive and safe, the Colorado Department of Transportation (CDOT) desires to install a twenty million dollar sprinkler system in the four-lane, 1.6 mile long Eisenhower-Johnson Memorial Tunnel on Interstate 70. This would undoubtedly make the tunnel safer. The CDOT has asked for Department of Homeland Security (DHS) funding to install a suppression system designed to control heat in the event of a fire, making it easier for fire fighters to enter the tunnel.

Fire safety in rail and road tunnels is challenging because of the specific features of the tunnel environment. A key factor to be aware of is that sprinkler systems are designed to confine a fire to its area of origin. According to a report by the National Fire Protection Association (NFPA), automatic sprinkler systems reduce the risk of home fire deaths and can significantly decrease fire-related property damage. Experts say that sprinklers will most likely extinguish the fire at its incipient stage before it has a chance to grow. The flow of water from fire sprinklers is also intended to drop the core temperature of a fire area. Once the temperature has dropped below what is known as the threshold temperature, fire crews can enter the area and completely extinguish it.

It is very important for one to remember that fire safety in tunnels is a challenging endeavor, mainly due to the specific features of the tunnel environment. A fire in a tunnel can spread from its original source to secondary vehicles very easily, so tunnel fires must be extinguished as quickly as they begin in order to stop it from reaching a critical heat-release rate. This can be achieved by “applying the wet stuff to the red stuff.”

Should we fear avian H5N1 influenza? – HSN

January 17, 2012 in 2012, Bio Terror, Emergency Medicine, Hazards

The only thing we have to fear is fear itself – Franklin D. Roosevelt

Why is there such widespread fear of avian H5N1 influenza virus?

Why did Paul Keim, chair of the National Science Advisory Board for Biosecurity (NSABB) say “I can’t think of another pathogenic organism that is as scary as this one”.  What lead Donald McNeil, writing about H5N1 in the New York Times, to conclude that “In its natural form, it is known to have infected only about 600 people since its discovery in 1997, but it killed more than half of them.”

McNeil’s statement is incorrect. Yet it summarizes why Paul Keim, the NSABB, and many others fear the virus.

The problem is that we cannot say with any certainty that the virus has infected only about 600 people. What we do know is that among the 600 seriously ill individuals infected with influenza H5N1 who are admitted to hospital, over half of them die.

To know the fatality rate of avian H5N1 influenza virus in humans, we need to divide the number of fatalities by the number of infections. We do not know that last number – but there are hints that it could be quite large. In a recent study of rural Thai villagers, sera from 800 individuals were collected and analyzed for antibodies against several avian influenza viruses, including H5N1, by hemagglutination-inhibition and neutralization assays. The results indicate that 73 participants (9.1%) had antibody titers against one of two different H5N1 strains. The authors conclude that ‘people in rural central Thailand may have experienced subclinical avian influenza virus infections’. A subclinical infection is one without apparent signs of illness.

If 9% of the rural Asian population has been subclinically infected with avian H5N1 influenza virus strains, it would dramatically change our view of the pathogenicity of the virus. Extensive serological studies must be done to determine the extent of human infection with avian H5N1 influenza viruses.

Until we know how many individuals are infected with avian influenza H5N1, we must refrain from making dire conclusions about the pathogenicity of the virus. Doing so has only lead us down a dangerous path of fearing that H5N1 influenza virus might be used as a weapon of bioterrorism, and restricting the publication of scientific papers on the virus.

Update. A meta-analysis reveals that about 1.3% of over 8,500 study participants had serological evidence of infection with influenza H5N1 (Palese, personal communication).
