- Listeriosis: Two cases of listeriosis, of which one was perinatal, were notified in October 2008, bringing the year to date total to 23. The non-perinatal case was aged 30-39 years and was hospitalised due to a chronic underlying illness. The perinatal case was aged 15-19 years and occurred at 36 weeks of gestation. The infant survived. No source was identified.
- Meningococcal disease: Based on the earliest date available1, 10 cases of meningococcal disease were notified during October 2008, 7 (70.0%) of which were laboratory-confirmed. In comparison, 12 cases were notified the previous month, September 2008, and 9 cases were notified during the same month last year, October 2007. For the 12 month period ending 31 October 2008, Hawke’s Bay DHB recorded the highest incidence rate of 6.5 per 100 000 population (10 cases), followed by Whanganui DHB (6.3 per 100 000, 4 cases), and West Coast DHB (6.2 per 100 000 population, 2 cases).The highest age-specific incidence rate was in infants aged less than one year (30.7 per 100 000 population, 19 cases), followed by those in the 1-4 years age group (13.0 per 100 000 population, 30 cases), and those in the 5-9 years age group (4.1 per 100 000 population, 12 cases).One child aged 1-4 years died from meningococcal disease during October.No samples were taken before the child died and there was no autopsy, therefore, no strain can be identified.
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.
