How does pneumonic plague occur?
The pneumonic form may occur following an initial bubonic or septicemic plague infection. It may also result from breathing in airborne droplets from another person or animal infected with pneumonic plague. The difference between the forms of plague is the location of infection; in pneumonic plague the infection is in the lungs, in bubonic plague the lymph nodes, and in septicemic plague within the blood. Diagnosis is by testing the blood, sputum, or fluid from a lymph node.
What is the Pneumonic Plague?
Pneumonic plague is a severe lung infection caused by the bacterium Yersinia pestis. Symptoms include fever, headache, shortness of breath, chest pain, and coughing. They typically start about three to seven days after exposure. It is one of three forms of plague, the other two being septicemic plague and bubonic plague.

What is the primary cause of pneumonic plague?
Primary pneumonic plague most often results from inhalation of infectious respiratory droplets; secondary pneumonia is metastatic from bubonic plague, most often transmitted by flea bites or direct contact with infected (including domestic) animals.
What is the primary plague?
Primary Plague Pneumonia: Acute, extensive lobar infiltrates progressing to bronchopneumonia and extending to opposite lung, at times associated with cavitation.
What causes pneumoniae to be progressive?
Rapidly progressive bacterial pneumonia very similar to pneumonic plague can be caused by Streptococcus pneumoniae, Staphylococcus aureus, Francisella tularensis, Legionella pneumophila and Coxiella burnetii. Similarly, severe viral pneumonia caused by influenza A and B viruses, hantavirus, and coronavirus mimic primary and secondary pneumonic plague.

What is plague?
Plague is an uncommon infectious disease of animals and humans caused by Yersinia pestis (Y. pestis) bacteria. Y. pestis is present in wild rodents and their fleas in many areas around the world, including most of the western United States.
Types of plague
Plague can be transmitted and cause illness in one or more of these forms:
How is pneumonic plague spread? What are the symptoms?
Pneumonic plague occurs when the Y. pestis bacterium is inhaled. The disease may be spread through face-to-face contact when an infected person coughs or sneezes. Because it enters the body by being inhaled, pneumonic plague could be spread intentionally if the bacteria were put into aerosol form.
Preventive measures
If you have symptoms, consult a healthcare provider as soon as possible. If you believe you have been intentionally exposed to pneumonic plague, you should contact law enforcement officials immediately.
Treatment for pneumonic plague
Early treatment with appropriate antibiotics is essential because untreated plague — especially the pneumonic form — is almost always fatal. You should use antibiotics to prevent or treat plague only under the direction of your healthcare provider or local health department.
What is the treatment for pneumonic plague?
People in close contact with very sick pneumonic plague patients may be evaluated and possibly placed under observation. Preventive antibiotic therapy may also be given, depending on the type and timing of personal contact.
How to tell if you have the plague?
Diagnosis is made by taking samples from the patient, especially blood or part of a swollen lymph gland, and submitting them for laboratory testing. Once plague has been identified as a possible cause of the illness, appropriate treatment should begin immediately.

The time between exposure to the bacteria and the onset of infection (incubation period) may be as little as 24 hours.
What is the most common form of the plague?
Bubonic plague ( lymph node infection): The most prevalent form of plague is bubonic plague, which can proceed to septicemic plague if left untreated. Y pestis enters the body through a bite from an infected flea or a cut or break in the skin. Swollen, painful lymph nodes are referred to as "buboes."
What is the most dangerous plague?
Pneumonic plague is the most dangerous type of plague caused by Yersinia pestis (Y pestis) and occurs when the bacterium infects the lungs. The disease can spread through the air from person to person.
What is the name of the disease that is transmitted by inhaling droplets of a sneeze?
Pneumonic plague (lung infection): When an infected individual coughs or sneezes, someone who inhales the droplets can develop the infection. Pneumonic plague may be purposely transmitted (as a bioweapon) if the bacterium was put into aerosol form.
What is the plague caused by?

The literature we assessed often stated that pneumonic plague is fatal in almost all patients who start antimicrobial drugs >24 hours after symptom onset. Generally, descriptions cite either 1 article, in which 11 patients treated within 24 hours survived and 2 treated after 24 hours died ( 11 ), or a handful of isolated case reports. However, case reports and series also exist in which patients survived despite starting antimicrobial drugs >24 hours after symptom onset ( 12 – 14 ).
What is the best treatment for the pneumonic plague?
To reduce the chance of death, antibiotics must be given within 24 hours of first symptoms. Streptomycin, gentamicin, the tetracyclines, and chloramphenicol are all effective against pneumonic plague.

Even so, when released into air, the bacterium will survive for up to one hour, although this could vary depending on conditions. Pneumonic plague is one of several forms of plague. Depending on circumstances, these forms may occur separately or in combination: Pneumonic plague occurs when Y. pestis infects the lungs.
How does the pneumonic plague spread?
Pneumonic plague occurs when Y. pestis infects the lungs. This type of plague can spread from person to person through the air. Transmission can take place if someone breathes in aerosolized bacteria, which could happen in a bioterrorist attack.
What is the bacterium that causes pneumonic plague?
Facts about Pneumonic Plague. Plague is an infectious disease that affects animals and humans. It is caused by the bacterium Yersinia pestis. This bacterium is found in rodents and their fleas and occurs in many areas of the world, including the United States. Y. pestis is easily destroyed by sunlight and drying.
What is the most common form of plague?
Bubonic plague is the most common form of plague. This occurs when an infected flea bites a person or when materials contaminated with Y. pestis enter through a break in a person’s skin. Patients develop swollen, tender lymph glands (called buboes) and fever, headache, chills, and weakness.
Can bubonic plague spread from person to person?
Bubonic plague does not spread from person to person. Septicemic plague occurs when plague bacteria multiply in the blood. It can be a complication of pneumonic or bubonic plague or it can occur by itself. When it occurs alone, it is caused in the same ways as bubonic plague; however, buboes do not develop.
Does the Septicemic Plague spread?
Patients have fever, chills, prostration, abdominal pain, shock, and bleeding into skin and other organs. Septicemic plague does not spread from person to person.
Overview
Treatment
Pneumonic plague is a very aggressive infection requiring early treatment. Antibiotics must be given within 24 hours of first symptoms to reduce the risk of death. Streptomycin, gentamicin, tetracyclines and chloramphenicol are all able to kill the causative bacterium.
Antibiotic treatment for seven days will protect people who have had direct, close contact with infected patients. Wearing a close-fitting surgical mask also protects against infection.
Signs and symptoms
The most apparent symptom of pneumonic plague is coughing, often with hemoptysis (coughing up blood). 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.
The pneumonia progresses for two to four days and may cause respiratory failure and shock. Pa…
Causes
Pneumonic plague can be caused in two ways: primary, which results from the inhalation of aerosolized plague bacteria, or secondary, when septicemic plague spreads into lung tissue from the bloodstream. Pneumonic plague is not exclusively vector-borne like bubonic plague; instead, it can be spread from person to person. There have been cases of pneumonic plague resulting from the dissection or handling of contaminated animal tissue. This is one of the types of plague for…
Modern outbreaks
Since 2002, the World Health Organization (WHO) has reported seven plague outbreaks, though some may go unreported because they often happen in remote areas. Between 1998 and 2009, nearly 24,000 cases have been reported, including about 2,000 deaths, in Africa, Asia, the Americas, and Eastern Europe. Ninety-eight percent of the world's cases occur in Africa.
