Legionnaires' bug found in Playboy mansion hot tub following DomainFest after 123 fall ill

At the DomainFest evening event in February at the Playboy Mansion in Los Angeles, over 100 people fell ill, with The Guardian reporting that the possible source is bacteria in the hot tub.
Of the 439 people that attended DomainFest, the Los Angeles health inspectors have found 123 people reported pneumonia and flu-like symptoms “including fever, headache, cough, shortness of breath and aches. Sixty-nine people fell sick on the day of the party. Three tested positive for H1N1 flu.”
Tests of water samples from the water in the hot tub identified the legionella bacterium, according to the Los Angeles health department.
However The Guardian says that “Officials say the bug in the pool may not be the cause of the outbreak. In a statement the Los Angeles County department of public health said: “Though legionella bacteria was identified in a water sample taken from the Playboy Mansion, this bacteria has not been determined as the source of the respiratory outbreak.
“Other potential causes under investigation include influenza, as three individuals who attended the conference tested later positive for the flu.”
