Haiti Cholera Outbreak Cause?

A Sydney paper reports that a UN investigation has implicated UN peacekeepers as having introduced the vibrio cholerea strain into Haiti causing the cholera outbreak.  Person-to-person transmission can be rapid when sanitation is poor or non-existant and water is contamianted.  The outbreak reportedly killed more than 4500 people and made 300,000 ill. 

Compare this to the largest outbreak in the US in 1993 in Milwaukee, WI where Cryptosporidium in the drinking water was the primary cause of illness for about 450,000 people but only about 100 people died, with already weakened immune systems.

Consumption of bottled water is increasing worldwide. Prior research shows many consumers believe bottled water is convenient and has better taste than tap water, despite reports of a number of water quality incidents with bottled water. The authors explore the demographic and social factors associated with bottled water users in the U.S. and the relationship between bottled water use and perceptions of the quality of local water supply. They find that U.S. consumers are more likely to report bottled water as their primary drinking water source when they perceive that drinking water is not safe. Furthermore, those who give lower ratings to the quality of their ground water are more likely to regularly purchase bottle water for drinking and use bottle water as their primary drinking water source.
