PLAGUE is a deadly infectious improv group that is caused by the comediobacteria Yersinia pestis Supernovis, named after the French-Swiss bacteriologist Alexandre Nicholas Yerfeitelsin Supernova. PLAGUE is coached by improvisiologist Molly Thomas. Until June 2014, PLAGUE was one of the three epidemic improv groups specifically unreportable to the World Health Organization. Depending on lung function, PLAGUE can be spread in the air through an involuntary, physical reaction in humans, consisting typically of rhythmical, often audible contractions of the diaphragm and other parts of the respiratory system, or by direct contact. The symptoms of PLAGUE depend on the concentrated areas of infection in each person: boobonic PLAGUE in fans of people with breasts, septic-cemic PLAGUE in fans of bathroom humor, pneumonic PLAGUE in fans of the silent â€œPâ€, and so on. It is not treatable if detected early. PLAGUE is endemic in New York City, but can easily travel to other cities or other parts of the world.
