Friday 27th April 2018


Summary of notifiable and other disease surveillance trends for 2010

In 2010, 17,277 cases of notifiable diseases were reported through EpiSurv, the National Notifiable Disease Database. This was lower than 2009, and the second lowest count in the last 14 years.

Between 2009 and 2010 there were some significant changes in the number of cases reported for individual diseases. There was a statistically significant increase in reported cases of cryptosporidiosis, giardiasis, legionellosis, rickettsial disease, tetanus and toxic shellfish poisoning. Conversely, there were statistically significant decreases in reported cases of dengue fever, gastroenteritis, hepatitis C, invasive pneumococcal disease, lead absorption, measles, meningococcal disease, mumps, non-seasonal influenza and pertussis.

In 2010, there were 606 outbreaks reported involving 6321 cases. This represented a decrease in the number of outbreaks and cases compared with 2009 figures. The most common pathogen implicated was norovirus, followed by Giardia spp. The most common settings linked to an outbreak were private homes and restaurants/caf├ęs.

The average weekly influenza consultation rate was 49.3 per 100 000 patient population in 2010, which was approximately half the 2009 rate. The peak weekly consultation rate of 151.6 per 100 000 patient population in August 2010 was lower than in 2009, but still higher than 2007 and 2008.

In 2010 Chlamydia trachomatis infection was again the most commonly diagnosed sexually transmitted infection (STI) in New Zealand, and it had over four-times the rate of the most commonly reported notifiable disease, campylobacteriosis.
