Tuberculosis in New Zealand: Annual Report 2010

Monday 23rd September 2019


Summary

There were 661 cases of tuberculosis (TB) notified in 2010. These notifications comprised 304 cases of TB disease (new and relapse/reactivation cases) and 357 cases of TB infection (treatment of latent infection and old disease on preventive treatment). Annual TB disease notification rates have more than halved between 1980 (15.1 per 100 000 population) and 2010 (7.0 per 100 000 population), although there has been little change in rates over the last five years.

Disease notification rates in 2010 were highest in those aged 30 to 39 years and in those of Asian ethnicity. More than half of the disease notifications were reported by the three District Health Boards (DHBs) in the Auckland region. The highest rates of TB disease were in Auckland DHB, followed by Counties Manukau and Capital and Coast DHBs.

Over three-quarters of the TB disease notifications in 2010 were culture positive, of which 250 were due to Mycobacterium tuberculosis and three were due to Mycobacterium bovis.

Of the 250 culture-positive cases due to M. tuberculosis in 2010, 55 had a non-unique molecular type. These cases were associated with 26 separate molecular types. The remaining 195 cases had a unique molecular type.

Over the last 10 years, there have been no significant changes in resistance to the five routinely tested antimicrobial drugs used to treat TB. In 2010, there were four cases of multidrug-resistant TB (MDR-TB). Notably, one of the 2010 MDR-TB cases was extensively drug-resistant (XDR-TB) and represents the first case of XDR-TB identified in New Zealand.
