Haemophilus influenzae from invasive disease

Laboratories throughout New Zealand are requested to refer all invasive isolates of H. influenzae to ESR as part of the laboratory-based surveillance of H. influenzae invasive disease. Until 2015, the antimicrobial susceptibility of these isolates was routinely tested and reported every year at ESR. Since 2015, the susceptibility of the invasive H. influenzae isolates referred to ESR is only being tested and reported every second year.

For data on antimicrobial susceptibility among H. influenzae from non-invasive disease, see the section General antimicrobial susceptibility data.
