The Bellevue-Stratford Hotel in July 1976, when it hosted a statewide convention of the American Legion. Soon after, a pneumonia-like disease killed 29 people and sickened 182 more who had been in the hotel. The vast majority were members of the convention. The negative publicity associated with what became known as "Legionnaires' Disease" caused occupancy at the Bellevue-Stratford to plummet to 4 percent and the hotel finally closed on November 18, 1976. In 1977, Dr. Joseph McDade discovered a new bacterium, which was identified as the causative organism. It thrives in hot, damp places like the water of the cooling towers for the
Pneumocystis pneumonia rare cause of pneumonia in neonates. It is commonly believed to be a commensal organism (dependent upon its human host for survival). The possibility of person-to-person transmission has recently gained credence, with supporting evidence coming from many different genotyping studies of "P. jirovecii" isolates from human lung tissue. For example, in one outbreak of 12 cases among transplant patients in Leiden, it was suggested as likely, but not proven, that human-to-human spread may have occurred. Since the start of the AIDS epidemic, PCP has been closely associated with AIDS. Because it only occurs in an immunocompromised host, it may be
