A new study by the University of Otago's department of public health, has found rates of bacterial infection were twice as likely for people living in rural / island locations on private water tank supplies than for their mainland counterparts on treated water supplies.
Campylobacterisos can be transmitted through drinking water or contaminated food, and is a
gastrointestinal tract infection that results in vomiting, diarrhoea, stomach pain, fever or nausea.
It was the most commonly reported gastrointestinal disease in New Zealand with 5000 to 6000
cases diagnosed each year, according to the National Notifiable Disease Surveillance data
base.
