Description:This image was captured during the necropsy of a rock squirrel, Spermophilus variegatus, formerly known as Citellus variegatus, which was afflicted with the pneumonic hemorrhagic plague. Note the presence of hemorrhagic blood that had been expelled from the animal’s nares, which had been the result of pulmonic hemorrhage.
Patients with pneumonic plague develops fever, headache, weakness, and a rapidly developing pneumonia with shortness of breath, chest pain, cough, and sometimes bloody or watery mucous. Pneumonic plague may develop from inhaling infectious droplets or may develop from untreated bubonic or septicemic plague after the bacteria spread to the lungs. The pneumonia may cause respiratory failure and shock. Pneumonic plague is the most serious form of the disease and is the only form of plague that can be spread from person to person (by infectious droplets).
