The Pneumonic plague as a result of the Bubonic plague
Intelligence Encyclopedia: Bubonic Plague
“A concern of health and defense officials is the possible deliberate introduction of plague—or the exploitation of plague—as a terrorist
weapon. Plague causing microorganisms are highly lethal, highly transmissible, and relatively easy to develop as terrorist weapons.
Bubonic plague is transmitted via fleas infected with Yersinia pestis. Pneumonic plague results from plague bacterium investing lung tissue. Pneumonic
plague exhibits an airborne form of transmission. Infection occurs from breathing aerosolized bacteria. Untreated pneumonic plague is highly
Bubonic plague is a disease that is typically passed from rodents to other animals and humans via the bite of a flea. The flea acquires the bacterium
that causes the disease as it lives on the skin of the rodent. Humans can also acquire the disease by direct contact with infected tissue.
The bacterium Pasteurella pestis is also known as Yersinia pestis, after one of its co-discoverers, Alexandre Yersin.
Prior to 1970, both United States and Soviet biological weapons programs developed techniques that enabled weapons developers to aerosolize plague
Bubonic plague is named because of the symptoms. The bacterial infection produces a painful swelling of the lymph nodes. These are called buboes.
Often the first swelling is evident in the groin. During the Middle Ages, a pandemic of bubonic plague was referred to as the Black Death, because of
the blackening of the skin due to the dried blood that accumulated under the skin's surface.
The bubonic plague has been a significant cause of misery and death throughout recorded history. The Black Death is only one of many epidemics of
plague that extended back to the beginning of recorded history. The first recorded outbreak of bubonic plague was in 542–543.
This plague destroyed the attempts of the Roman emperor of the day to re-establish a Roman empire in Europe. This is only one example of how bubonic
plague has changed the course of history.
The plague of London in 1665 killed over 17,000 people (almost twenty percent of the city's population). This outbreak was quelled by a huge fire
that destroyed most of the city.
The disease remains present to this day. In North America, the last large epidemic occurred in Los Angeles in 1925. With the advent of the antibiotic
era, bubonic plague has been controlled in the developed world. However, sporadic cases (e.g., 10 to 15 cases each year) still occur in the western
United States. In less developed countries (e.g., in Africa, Bolivia, Peru, Ecuador, Brazil) thousands of cases are reported each year.
The infrequency of bubonic plague outbreaks does not mean the disease disappears altogether. Rather, the disease normally exists in what is called an
enzootic state. That is, a few individuals of a certain community (e.g., rodents) harbor the disease. Sometimes, however, environmental conditions
cause the disease to spread through the carrier population, causing loss of life. As the rodent populations dies, the fleas that live on them need to
find other food sources. This is when the interaction with humans and non-rodent animals can occur. Between outbreaks, Yersinia pestis infects rodents
without causing much illness. Thus, the rodents become a reservoir of the infection.
Symptoms of infection in humans begin within days after contamination with the plague bacterium. The bacteria enter the bloodstream and travel to
various organs (e.g., kidney, liver, spleen, lungs) as well as to the brain. Symptoms include shivering, nausea with vomiting, headache, intolerance
to light, and a whitish-appearing tongue. Buboes then appear, followed by rupture of blood vessels. The released blood can coagulate and turn
If the infection is untreated, the death rate in humans approaches 75%. Prompt treatment most often leads to full recovery and a life-long immunity
from further infection. Prevention is possible, since a vaccine is available. Unfortunately, the vaccine is protective for only a few months. Use of
the vaccine is usually reserved for those who will be at high risk for acquiring the bacterial infection (e.g., soldiers, travelers to an outbreak
region). Antibiotics such as tetracycline or sulfonamide are used more commonly as a precaution for those who might be exposed to the bacterium. Such
use of antibiotics should be stopped once the risk of infection is gone, to avoid the development of resistance in other bacteria resident in the
The most effective way to prevent bubonic plague is the maintenance of adequate sanitary conditions. This acts to control the rodent population,
especially in urban centers.
In 1970, a World Health Organization study concluded that deliberate dissemination of 110 lbs (50 kg) of aerosolized Y pestis over a city with a
population of approximately 5 million people could potentially result in 150,000 cases of pneumonic plague. Half of these cases would require advanced
medical care and approximately 20% would be expected to perish.”

This article is about the disease in general. For information about the medieval European plague, see Black Death.
“Bubonic plague is the best known manifestation of the bacterial disease plague, caused by the Gram-negative bacterium Yersinia pestis (formerly
known as Pasteurella pestis). It belongs to the family Enterobacteriaceae. The term "bubonic plague" was often used synonymously for plague, but it
does in fact refer specifically to an infection that enters through the skin and travels through the lymphatics, as is often seen in flea-borne
infections. Bubonic plague kills about half of infected patients in 3–7 days without treatment, and may be the Black Death that swept through Europe
in the 1340s, killing tens of millions.”
Could this new plague be a mutated virus intended as a Bio-terrorism weapon ?
“Plague was used during the Second Sino-Japanese War as a bacteriological weapon by the Imperial Japanese Army. These weapons were provided by
Shirō Ishii's units and used in experiments on humans before being used on the field. For example, in 1940, the Imperial Japanese Army Air Service
bombed Ningbo with fleas carrying the bubonic plague. During the Khabarovsk War Crime Trials the accused, such as Major General Kiyashi Kawashima,
testified that, in 1941, some 40 members of Unit 731 air-dropped plague-contaminated fleas on Changde. These operations caused epidemic plague
It does make me consider the question..
Is this new death machine a“man made”
