Pneumonic plague is a severe lung infection caused by the bacterium Yersinia pestis.
It causes the disease plague, which takes three main forms: pneumonic, septicemic, and bubonic plagues.


Bubonic plague

It is one of three forms of plague, the other two being septicemic plague and bubonic plague.
The three types of plague are the result of the route of infection: bubonic plague, septicemic plague, and pneumonic plague.







Plague (disease)

It is one of three forms of plague, the other two being septicemic plague and bubonic plague.
In the bubonic form there is also swelling of lymph nodes, while in the septicemic form tissues may turn black and die, and in the pneumonic form shortness of breath, cough and chest pain may occur.






Septicemic plague
septicaemic plaguesepticemicPlague, septicemic
It is one of three forms of plague, the other two being septicemic plague and bubonic plague. Pneumonic plague can be caused in two ways: primary, which results from the inhalation of aerosolised plague bacteria, or secondary, when septicaemic plague spreads into lung tissue from the bloodstream.
It is the rarest of the three plague varieties; the other forms are bubonic and pneumonic plague.


Hemoptysis

The most apparent symptom of pneumonic plague is coughing, often with hemoptysis (coughing up blood).
Less common causes include aspergilloma, bronchiectasis, coccidioidomycosis, pulmonary embolism, pneumonic plague, and cystic fibrosis.

Black Death

Some hypothesize that the pneumonic version of the plague was mainly responsible for the Black Death that resulted in approximately 50 million deaths in the 1300s.
Some accounts, like that of Lodewijk Heyligen, whose master the Cardinal Colonna died of the plague in 1348, noted a distinct form of the disease that infected the lungs and led to respiratory problems and is identified with pneumonic plague.









Airborne disease

It may also result from breathing in airborne droplets from another person or cat infected with pneumonic plague.
They also may be used in dealing with air-borne bacterial primary infections, such as pneumonic plague.

Ziketan
An outbreak of the disease in China began in August 2009 in Ziketan Town located in Qinghai Province.
On August 2, the authorities quarantined Ziketan after a dozen people were sickened with pneumonic plague, a lung infection that can kill a human in 24 hours if left untreated.

It is recommended that those infected be isolated from others.

Sputum

With pneumonic plague, the first signs of illness are fever, headache, weakness and rapidly developing pneumonia with shortness of breath, chest pain, cough and sometimes bloody or watery sputum.

Shock (circulatory)
