Above is a link to WebMD. The travel alert caught my attention and I went to WebMD for some info. This article kicked out on my search.
excerpt from the article - ...."Plague is a severe febrile illness. Pneumonic plague, the most fatal form of the infection, can develop from inhalation of plague bacilli (primary pneumonic plague) or from hematogenous spread secondary to septicemic plague. Approximately 12% of cases of bubonic and primary septicemic plague develop into secondary pneumonic plague. Conversely, septicemic plague can be secondary to primary pneumonic plague.
The incubation period for pneumonic plague is typically 2 to 4 days (range, 1 to 6 days). Presenting symptoms typically include the acute onset of malaise, high fever, chills, headache, chest discomfort, dyspnea, and cough concomitant with or followed rapidly by clinical sepsis. Hemoptysis is a classic sign that should suggest plague in the appropriate clinical context, but sputum may be watery or purulent. Gastrointestinal symptoms may be prominent with pneumonic plague; these include nausea, vomiting, diarrhea, and abdominal pain. A cervical bubo is infrequently present.
The disease is rapidly progressive, with 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. Abnormalities on chest x-ray are variable but frequently show bilateral patchy infiltrates or consolidation. The mortality for pneumonic plague is reported to be 57% and is extremely high when initiation of treatment is delayed beyond 24 hours after symptom onset...."
YIKES!!!!!!!!!!!!!
