| The major form of the plague that will be present on a chest x-ray will be pneumonic plague. Pneumonic plague is caused by the same bacteria that gives rise to the bubonic plague, but it is just located in a different area of the body. The bubonic plague is an infection of the [[lymphatic system]], whereas pneumonic plague is an infection of the [[respiratory system]]. Normally, the pneumonic form is developed due to an initial spread of the bubonic form. It commonly presents with coughing accompanied by [[hemoptysis]] Untreated, it possesses an extremely high fatality rate.

| ==Chest X Ray==
| |
| Pneumonic plague is rapidly progressive. Patients experience increasing [[dyspnea]], [[stridor]], and [[cyanosis]]. Rapidly progressive respiratory failure and [[sepsis]] within 2 to 4 days of onset of [[illness]] is typical of pneumonic plague.

| Chest x-rays can be variable but frequently show bilateral patchy infiltrates or consolidation, such as the 1st image below.
