Assessing the Biological Weapons and Bioterrorism Threat

[JJackson]

Mother Nature is the most dangerous terrorist. The microbial world is almost unlimited in its [terrorist] potential

Bioengineering pathogens is at the extremes of our abilities (man’s that is) we have recently 'created life' from scratch for the first time. This was a fairly big deal but all we did was manufacture some DNA to match that of another organism, we do not know enough to make even minor changes to the genetic sequence and be able to predict the effects. The money thrown at bio-terrorism has had two effects (well three if you include that it was diverted from some where it might have done more good) firstly it has probably increased the threat to US citizens from dangerous biological agents by vastly increasing the number of US labs licensed to work with dangerous pathogens. There has, naturally enough, been a commensurate increase in the number of lab accidents, researchers infected etc. (link to post on Texas A&M University lab failures that eventually made the CDC do something). The second, and beneficial effect, of bio-terrorism research has been the fact that a lot of it is dual use and could be of genuine benefit in what is the far greater, and very real danger, posed by zoonotic emergence - H5N1 being the poster-boy candidate. In this field, to paraphrase Ex. Sec. Rumsfeld, it is the known unknowns that we should be losing sleep over HIV/AIDS, SARS, Nipah, Ebola/Marburg etc. are all recent zoonotics. None of our (human) communicable diseases was originally a human disease from Yellow fever & Smallpox to cold & flu they have all been acquired by humans from - and since - the domestication of animals.

H5N1 an object lesson.
For the first time in history we have been given forewarning of an impending zoonotic emergence and it is a humbling (humiliating might be closer) lesson in how poor a match our technology is to this very basic virus' ability to mutate away from any solution we may try and develop. HIV is a classical zoonotic pandemic and despite the research effort over a quarter of a century this is the first year in which we may have broken even. A flu pandemic would follow the same course but due to the difference in its transmission method would reach the same point in the pandemic cycle in about three months. We have no vaccines and no likelihood of producing any in the foreseeable future, we have one antiviral (Tamiflu) that has shown some usefulness (not a cure but can reduce symptoms) but resistance is rapidly developing in seasonal flu and most epidemiological models show this becoming the norm early in a pandemic. Here is an enemy that is a truly worthy advisory only full scale nuclear war can come close to matching its potential for destruction of our cosy human existence.
Y’all have a nice day now.
