While it's true that Legionnaire's disease hasn't received this much media attention since the landmark 1976 outbreak that left 221 ill and 34 dead, the same bacteria that recently caused a stink at the Playboy Mansion affects thousands of Americans each year.
The Centers for Disease Control and Prevention (CDC) reports that between 8,000 and 18,000 people in the U.S. are hospitalized per annum due to Legionnaire's Disease, though according to Environmental-Expert.com, this might not be an accurate portrait of the problem, as experts believe that most cases go undiagnosed.
According to the news source, the bacteria that causes the disease can be found in water (as was later discovered at Hugh Hefner's palace), but the actual transmission occurs when people breathe in contaminated vapors.
Perhaps it wouldn't have hurt to install an air purifying system or two at the Mansion. Those who wish to help prevent such outbreaks and improve their overall respiratory health have every reason to look into a medical-grade purifier from FreshAirPro, many of which are proven to remove over 99 percent of particulate matter from the air as well as a range of harmful viruses and bacteria.
