Sexually Transmitted Infections in NZ: Annual Surveillance Report 2010

Thursday 24th October 2019


Summary of sexually transmitted infections in New Zealand in 2010

In New Zealand, sexually transmitted infections (STIs) are not notifiable. Therefore, surveillance efforts are based on the voluntary provision of data from several different sources (sexual health clinics (SHCs), family planning clinics (FPCs), student and youth health clinics (SYHCs) and laboratories). Population and disease coverage varies with the data source.

This report summarises the epidemiology of STIs in 2010, and examines trends since 2006. It covers the STIs of public health importance, including chlamydia, gonorrhoea, genital herpes, genital warts, syphilis, non-specific urethritis (NSU), chancroid, granuloma inguinale (GI) and lymphogranuloma venereum (LGV).

Chlamydia was the most commonly reported STI in 2010. A national chlamydia rate (based on 15 DHBs) of 782 per 100 000 population was estimated from laboratory surveillance data. Over 70% of cases reported through laboratory surveillance data were aged between 15 and 24 years, and there were 104 cases of chlamydia in infants. For both SHCs and SYHCs, the clinic visit rate for chlamydia and the number of reported cases of chlamydia increased from 2006 to 2010. In contrast, FPCs reported a decrease in the chlamydia clinic visit rate and number of cases over the same time period.

In 2010, a national gonorrhoea rate (based on 17 DHBs) of 65 per 100 000 population was estimated from laboratory surveillance data. Over 60% of cases reported by laboratories were aged between 15 and 24 years, and there were three cases of gonorrhoea in infants. From 2006 to 2010, SHCs and SYHCs reported an increase in the clinic visit rate for gonorrhoea and the number of gonorrhoea cases, while FPCs reported a decrease in both.

The number of cases of syphilis reported by SHCs decreased from 138 cases in 2009 to 119 cases in 2010. One additional case was reported by a FPC and two cases were reported by SYHCs. 2010 was the first year in recent times to show a decline in reported syphilis cases.

From 2009 to 2010, SHCs reported a decrease in the genital herpes, genital warts and NSU clinic visit rates.

No cases of chancroid, GI and LGV were reported in 2010.
