Wednesday 24th October 2018


Key notifiable disease trends

Legionellosis: 17 cases (8 confirmed, 1 probable and 8 under investigation) of legionellosis were notified in June 2018 compared with 5 in June 2017. There was one death from legionellosis reported in a female aged 30–39 years. The majority (7/9, 77.8%) of confirmed and probable cases were aged over 40 years. Three of the confirmed and probable cases had exposure to potting mix or compost and one had exposure to a cooling tower.

Meningococcal Disease: A case of meningococcal disease that was reported in January 2018 has recently been confirmed by whole genome sequencing as being due to group X. This is the first known case of group X invasive meningococcal disease in New Zealand. The case was aged 50–59 years and no overseas travel was reported. Group X has been reported as causing epidemics of invasive meningococcal disease in the African region. For more information see Global epidemiology of invasive meningococcal disease.

Pertussis: 169 cases (92 confirmed, 66 probable, 1 suspect and 10 under investigation) of pertussis were notified in June 2018, compared with 121 cases in June 2017. While pertussis cases have been decreasing since the peak in January 2018, this is not unusual and cases may increase again. For more information see the latest Pertussis Report.

Yersiniosis: 601 cases of yersiniosis were notified from January to June 2018, compared with 405 for the same period in 2017. This increase is partly due to changes in laboratory testing practices since mid-2017, with the use of increasingly sensitive assays for enteric diseases and screening of all faecal specimens. For further information see the 2016 Annual Notifiable Disease Report Commentary.
