Playboy Mansion visitors hit with mystery illness - legionela

L.A. County health officials are investigating a possible respiratory infection outbreak after dozens of illnesses are reported by people who attended a recent fundraiser.
Many who have reported falling ill after the event suspect that their symptoms are related to legionellosis, or Pontiac fever. A milder form of Legionnaires' disease, legionellosis is caused by a bacterium that grows in warm water and can take root in hot tubs or parts of air-conditioning systems, according to the Centers for Disease Control and Prevention. The bacteria are not spread from person to person, according to the CDC, but are instead inhaled in water vapor.
Some of those who became ill said they suspected a fog machine that was used at the party.
DN Journal, a website that reports on Internet domain commerce, broke the story when it wrote that a Swedish attendee returned home and tested positive for the Legionella bacterium.
