The Otago case worked as a shearer in the United States during the incubation period. No risk factor information is currently recorded for the remaining two cases.
  • Campylobacteriosis: The number of campylobacter notifications has continued to drop from 380 in May 2008 to 275 in June 2008 (Figure 1). For the 12 month period ending 30 June 2008 the national rate was 201.7 per 100 000 population compared to 358.0 for the same 12 month period last year.
  • Cryptosporidiosis: 24 cryptosporidiosis cases were notified in June 2008 compared to 47 cases notified in the same month of the previous year. For the 12 month period ending 30 June 2008 the national rate was 15.9 per 100 000 population compared to 23.5 for the same 12 month period last year.
  • Leprosy: One case of leprosy, still under investigation, was notified in June 2008. The case was from Counties Manukau DHB. No risk factor information is currently recorded.
  • Meningococcal disease: Based on the earliest date available1, 12 cases of meningococcal disease were notified during June 2008, eight (66.7%) of which were laboratory-confirmed. In comparison, seven cases were notified the previous month, May 2008, and eight cases were notified during the same month last year, June 2007. For the 12 month period ending 30 June 2008, Hawke’s Bay DHB recorded the highest incidence rate of 8.5 per 100 000 population (13 cases), followed by Tairawhiti (6.5 per 100 000, 3 cases), Capital and Coast (3.9 per 100 000, 11 cases), and Northland (3.9 per 100 000, 6 cases). The highest age-specific incidence rate was in infants aged less than one year (27.5 per 100 000 population, 17 cases), followed by those in the 1-4 years age group (14.7 per 100 000 population, 34 cases), and those in the 5-9 years age group (5.9 per 100 000 population, 17 cases).
  • Pertussis: 25 cases of pertussis were notified in June 2008 bringing the year to date total to 138. Only 2 (8.0%) were laboratory-confirmed. The highest number of cases were reported from Waikato (6) and Canterbury (4) DHBs. For the previous 12 months, Waikato DHB had the highest incidence rate of 21.0 per 100 000 population (6 cases) compared to a national rate of 6.9 per 100 000 population. The current rate by age group was highest amongst infants aged less than one year (50.2 per 100 000 population, 31 cases), followed by children in the 1-4 years age group (14.3 per 100 000 population, 33 cases), and children in the 10-14 years age group (8.5 per 100 000 population, 26 cases).
  • Rickettsial disease: Two cases of rickettsial disease, both under investigation were notified in June 2008. The cases were from Counties Manukau and Waitemata DHBs. The Counties Manukau case was originally from Fiji and the disease was detected as part of a pre-employment health check. The Waitemata case’s probable source of exposure was close contact with a cat that catches rats and mice.
  • Taeniasis: One case was notified with taeniasis in June 2008. The case was from Capital and Coast DHB and had been in Ethiopia during the incubation period.
  • VTEC/STEC: 10 cases of VTEC/STEC were notified in June 2008 compared to four notified cases in the same month of the previous year (Figure 2). The cases were reported from Waikato (3), Counties Manukau (2), Taranaki (1), MidCentral (1), Nelson Marlborough (1), Canterbury (1), and Southland (1) DHBs. Two cases were hospitalised. The cases were in the following age groups:1-4 years (4), 5-9 years (2), 60-69 years (2), 20-29 years (1), and 30-39 years (1).VTEC O157 was isolated for nine of the cases.


1The ‘earliest’ date refers to the earliest recorded date for the case (onset or hospitalisation date rather than report date, if available). ‘Earliest’ date, as opposed to ‘report date’ alone, is used throughout the analysis of meningococcal disease notification data.
