The following background information on campylobacteriosis in New Zealand is abstracted from Gideon www.GideonOnline.com and the Gideon e-book series. [1-2] (primary references available on request)
The incidence of campylobacteriosis exceeds that of any other reportable disease in New Zealand. In fact, Campylobacteriosis accounted for 42.5% of all notified cases of infectious disease in 2010. Highest rates are reported during late spring and early summer (November to January). Rates on South Island are correlated with lower socio-economic level, proportion of persons ages 25 to 44 and density of fresh food outlets. The Far North and much of the rural North Island report relatively low disease incidence during summer, with minimal inter-seasonal variation. Highest summer incidence and inter-seasonal variation are reported in Christchurch, Dunedin, much of the South Island, Wellington and Upper Hutt. 47% of campylobacteriosis cases are acquired from food, 28% direct animal contact, 7% overseas travel, 4% person-to-person transmission and 3% water-related.
The following graph compares the yearly reported incidence of six diseases associated with diarrhea. Note that giardiasis is more common than salmonellosis, shigellosis and VTEC (verotoxin-producing Escherichia coli) infections in this country. Significantly, 2,056 patients were hospitalized for Guillain-Barre syndrome (a condition which often complicated campylobacteriosis) during 1988 to 2010. Decreasing rates of campylobacteriosis since 2007 were ascribed to efficient disease control among poultry.
In the second graph, I’ve contrasted rates of campylobacteriosis in New Zealand with those of other English-speaking countries.
