Plague is an infection. Governments have studied the bacteria's use as a germ-warfare weapon. As a weapon, it would be released in the air. The types of plague are:
The plague is treated with isolation and antibiotics.
Plague is caused by specific bacteria.
Bubonic and septicemic plagues are spread by bites from infected fleas. Transmission can also occur when a person comes in contact with infected tissue or body fluids from another person or animal.
Pneumonic plague is spread by droplets in the air when an infected person coughs or sneezes. The disease is transmitted to another person when the droplets are inhaled. Transmission by droplets is the only way pneumonic plague spreads among people.

Starting antibiotics early is essential. Any delay greatly increases the risk of death. The drugs are injected in a muscle or given through a vein. Later in treatment, some drugs can be given by mouth. A patient with lung symptoms will be placed in isolation to protect others. Caregivers and visitors should wear a mask, gloves, goggles, and a gown. Cases are reported to public health officials.
Health professionals will monitor the patient for changes in status and take appropriate action. Maintaining adequate heart function, blood pressure, and oxygen supply are of prime importance.
Antibiotics may prevent infection following close contact with someone who has the disease. The drugs should be taken daily while in contact, and for seven days after the last exposure. In addition, the caregiver and patient should wear masks.
In the event of a terrorism exposure, antibiotics may be given to patients in the areas with fever or cough. A vaccine does not exist for pneumonic plague.
