Nonintentional Pathogen Releases Certain kinds of biological assaults can be predicted with even higher confidence than bioterrorist attacks. It would be relatively easy to engineer a new flu strain combining qualities from varieties that spread like wildfire with varieties that were deadly.
For further indication of which pathogens make effective biological weapons, one could look at the agents studied by the United States when it had an offensive biological weapons research program. VEE virus has the capacity to produce epidemics.
Organisms like fungi that have not been associated with major epidemics tend to be ignored in threat analysis scenarios despite the fact that this kingdom, as a whole, includes many species with high weapon potential Casadevall and Pirofski, and the fact that fungal diseases are currently decimating certain amphibian and bat populations.
Smallpox, Ebola, and Marburg virus might be chosen because they have a reputation for causing a more horrifying illness. Staphylococcal enterotoxin is one of the most common causes of food poisoning. Pneumonic plague's person-to-person communicability and untreated case-fatality rate of at least twice that of tularemia make it more effective than tularemia as an agent to cause mass illness.
At this time this writer can identify at three major existential threats to humanity: Two types of smallpox generally are recognized.
One incident was the intentional contamination of salad bars in restaurants in Oregon by the Rajneeshee cult during late September 7 Moreover, a respirable aerosol of germs can be achieved through other high-pressure devices.
Additional attributes that make an agent even more dangerous include being communicable from person to person and having no treatment or vaccine.
In the USA, the offensive biological weapons program was terminated by President Nixon by executive orders in and 7. Victims may have certain signs on a chest X-ray. Because of the agent's incubation period, the perpetrators might be gone before anyone knew that an attack had been made.
The risk of infection is increased greatly if humans are exposed while these animals are giving birth to young. To be used for a maximum credible event, an agent must have some of the following properties:Biological warfare (BW)—also known as germ warfare—is the use of biological toxins or infectious agents such as bacteria, viruses, and fungi with the intent to kill or incapacitate humans, animals or plants as an act of war.
Variola represents a significant threat as a biological warfare agent. Variola is highly infectious and is associated with a high death rate and secondary spread.
Currently, the majority of the U.S. population has no immunity, vaccine is in short supply, and no effective treatment exists for the disease. Variola represents a significant threat as a biological warfare agent. Variola is highly infectious and is associated with a high death rate and secondary spread.
Currently, the majority of the U.S. population has no immunity, vaccine is in short supply, and no effective treatment exists for the disease. Aug 24, · In this regard, microbial threat lists are primarily populated with agents that have been investigated by the military for biological warfare use, such as Bacillus anthracis, or have caused terrible epidemics in history, such as variola major and Yersinia pestis.
Chemical/biological warfare is the term used to describe the use of chemical or biological agents as weapons to injure or kill humans, livestock, or plants. Chemical weapons are devices that use chemicals to inflict death or injury; biological weapons use pathogens or organisms that cause disease.
Biological warfare is as old as civilization, observes Block, but it was international revulsion over the widespread use of poisonous mustard gas during World War I that finally led to aDownload
