Campylobacter, Salmonella, Cryptosporidium and Giardia cause diarrhoeal illnesses in thousands
of people annually in New Zealand. The incidence of these infections is significantly higher in New Zealand compared to most other developed
nations. Animal, environmental and waterborne sources are a common cause of isolated illnesses and outbreaks, and exposure to these sources
is a significant risk-factor for infection. This edition of the rural infections series focuses on these four notifiable pathogens, each of
which causes a similar set of symptoms, and discusses the investigation and management of diarrhoeal illnesses in a person with rural
occupation, residence or recent contact with animals or untreated water.
