Key findings of meningococcal disease surveillance in 2010

Ninety-six cases of meningococcal disease were notified in 2010, which equates to a rate of 2.4 per 100 000 population.  The rate of disease of 2.4 per 100 000 in 2010 was still significantly higher than the pre-epidemic rate of 1.5 per 100 000 (1989–1990).

In 2010, the highest District Health Board (DHB) rates were recorded in Hutt Valley  and Hawke’s Bay DHBs. No cases were reported from Whanganui, Wairarapa and South Canterbury DHBs.

The highest age-specific rates of disease continued to occur in children younger than 5 years of age in 2010.
Although age-standardised rates have decreased significantly for all ethnic groups, Māori and Pacific Peoples continue to experience higher rates of disease than the European population.

In 2010, 30.9% of confirmed cases able to be typed were due to the epidemic strain type defined as group B or non-groupable meningococci with the P1.7-2,4 PorA type.

Six deaths occurred in 2010, giving a case-fatality rate of 6.3%.

Of the 62 meningococcal isolates recovered from cases in 2010, 29% had reduced susceptibility to penicillin, but all were susceptible to ceftriaxone and rifampicin. Ciprofloxacin resistance was identified among invasive meningococci in New Zealand for the first time in 2010 in one group C isolate.
