There are three main types of plague: bubonic, septicemic, and pneumonic. Bubonic plague is the most common form and is characterized by the swelling of lymph nodes (buboes) in the groin, armpit, or neck. Septicemic plague occurs when the bacteria enter the bloodstream and cause widespread infection. Pneumonic plague is the most severe form and occurs when the bacteria infect the lungs.
Plague is a very serious disease and can be fatal if not treated quickly. Treatment typically involves antibiotics and supportive care.
How Plague Spreads
Plague is typically spread by fleas that have fed on infected rodents. When a flea bites an infected rodent, the bacteria Yersinia pestis is ingested by the flea. The bacteria then multiplies in the flea's gut and is eventually passed out in the flea's feces. When the flea bites another animal or human, the bacteria can be transmitted to the new host.
Plague can also be spread through contact with infected animals or humans. This can occur when a person comes into contact with the blood or other bodily fluids of an infected person or animal. Plague can also be spread through the inhalation of infected droplets. This can occur when an infected person coughs or sneezes and the droplets are inhaled by another person.
Symptoms of Plague
The symptoms of plague vary depending on the type of plague.

* Fever
* Chills
* Headache
* Weakness
* Nausea
* Vomiting
* Diarrhea
Septicemic plague occurs when the bacteria enter the bloodstream and cause widespread infection. Symptoms of septicemic plague include:
* Fever
* Chills
* Headache
* Weakness
* Nausea
* Vomiting
* Diarrhea
* Abdominal pain
* Bleeding from the nose, mouth, or rectum
Pneumonic plague is the most severe form of plague and occurs when the bacteria infect the lungs. Symptoms of pneumonic plague include:

* Headache
* Weakness
* Cough
* Shortness of breath
* Chest pain
* Nausea
* Vomiting
* Diarrhea
Treatment for Plague
Plague is a very serious disease and can be fatal if not treated quickly. Treatment typically involves antibiotics and supportive care.
Antibiotics that are effective against plague include:
* Streptomycin
* Gentamicin
* Doxycycline
* Ciprofloxacin
Supportive care may include:
* Fluids and electrolytes
* Oxygen therapy
* Mechanical ventilation
* Blood transfusions
Prevention of Plague
There are a number of things that can be done to prevent plague, including:
* Avoiding contact with infected rodents and fleas
* Wearing insect repellent when in areas where there is a risk of plague
* Taking antibiotics before and after traveling to areas where there is a risk of plague
* Getting vaccinated against plague
