Several factors delayed the diagnosis of
pneumonic plague, resulting in many potential exposures.
Pathology of experimental
pneumonic plague produced by fraction 1-positive and fraction 1-negative Yersinia pestis in African green monkeys (Cercopithecus aethiops).
Dubai: The UAE Ministry of Health and Prevention has warned residents against travelling to the Republic of Madagascar after the reported outbreak of
pneumonic plague in the African country.
The rodents are divided into five subgroups; those who have not contracted the disease but may get it if they get in contact with [I.sub.HS], [I.sub.HP], [I.sub.RS], [I.sub.HP], [I.sub.F], or A, referred to as susceptible rodents and denoted by [S.sub.R]; those who have the disease but have not shown any symptom and are incapable of transmitting the disease referred to as exposed and denoted by [E.sub.R]; those who are infected and capable of transmitting the disease are divided into three subgroups: those who have bubonic plague denoted by [I.sub.RB], those with septicemic plague denoted by [I.sub.RS], and those who have
pneumonic plague [I.sub.RP].
The symptoms exhibited by the patients were definitely consistent with
pneumonic plague, and the pathologists had sent a sample overnight to the CDC for confirmation.
pestis was initially passed from person to person--say, when an infected individual coughed on a healthy person--and most likely caused lung infections known as
pneumonic plague or blood infections called septicemic plague, the researchers report in the Oct.
Pneumonic plague is one of the most deadly infectious diseases and can kill people within 24 hours.
Pneumonic plague may develop as the lungs become infected and it is especially dangerous because it may easily be spread by coughing.
If the bacteria reach the lungs, the patient develops pneumonia (
pneumonic plague), which is transmissible from person to person through infected droplets spread by coughing.
It is the first case of
pneumonic plague seen in the state since 2004, said Jennifer House, a spokeswoman for the Colorado Department of Public Health and Environment.
According to scientists working at Public Health England in Porton Down, the plague was a
pneumonic plague instead of the bubonic plague with infection spreading from human to human, rather than by rat fleas.
