I don't understand why quarantine isn't used more often? Particularly in this case? It just seems like we've been lucky so far is all...
TextUntreated pneumonic plague has a mortality of nearly 100%. Some hypothesize that the pneumonic version of the plague was mainly responsible for the Black Death that resulted in approximately 50 million deaths in the 1300s
"The risk of international spread is low, because generally, people with plague are too sick to travel," Ndiaye told CNN in a previous report. She explained WHO is working closely with Madagascar's airport authorities to ensure control measures -- such as temperature checks and medical teams -- are in place at airports and ports to prevent the spread of infection outside the country.
Patients in the early stage of pneumonic plague (approximately the first 20–24 h) apparently pose little risk . This is likely because of the low counts of bacteria in their respiratory secretions and the general absence of coughing. Patients in the final stages of disease who cough sputum with much visible blood and/or pus pose the highest risk
Spread Pneumonic plague can be caused in two ways: primary, which results from the inhalation of aerosolised plague bacteria, or secondary, when septicaemic plague spreads into lung tissue from the bloodstream. Pneumonic plague is not exclusively vector-borne like bubonic plague; instead it can be spread from person to person. There have been cases of pneumonic plague resulting from the dissection or handling of contaminated animal tissue. This is one type of the plague formerly known as the Black Death.
Treatment Pneumonic plague is a very aggressive infection requiring early treatment. Antibiotics must be given within 24 hours of first symptoms to reduce the risk of death. Streptomycin, gentamicin, tetracyclines and chloramphenicol are all effective against pneumonic plague. Antibiotic treatment for seven days will protect people who have had direct, close contact with infected patients. Wearing a close-fitting surgical mask also protects against infection. The mortality rate from untreated pneumonic plague approaches 100%
