patients nationwide. Influenza activity was also very low among those hospitalised patients in Auckland
and Counties Manukau District Health Boards.

 Influenza-like illness (ILI) and severe acute respiratory illness (SARI) surveillance
ILI surveillance: One hundred and four patients with influenza-like illness consulted sentinel general
practices in 20 DHBs. The weekly ILI incidence was 19.7 per 100 000 patient population (Figure 1),
below the seasonal threshold of ILI consultations. The ILI related influenza incidence (adjusted) was
11.9 per 100 000 patient population.

SARI surveillance: There were 2706 acute admissions to ADHB and CMDHB hospitals this week. Of
the 188 patients with suspected respiratory infections, 72 (38.3%) patients met the SARI case
definition. Five SARI cases were admitted to ICU and no SARI related deaths were reported. The
weekly SARI incidence was 5.9 per 100 000 population. The SARI related influenza incidence was 1.5
per 100 000 population.

 Respiratory pathogen surveillance
Influenza virus: During this week, 58 ILI specimens were tested, 35 were positive for influenza
viruses. In addition, 47 SARI specimens were tested, 16 were positive for influenza viruses. For details,
see Table 3 and Figures 5 and 6.

Non-influenza respiratory viruses: For cumulative totals, see Table 4 and Figures 7 and 8.

ILI counts and rates by DHB by week are available in the Appendix.

SARI surveillance: There were 2810 acute admissions to ADHB and CMDHB hospitals this week. Of
the 181 patients with suspected respiratory infections, 75 (41.4%) patients met the SARI case
definition. Four SARI cases were admitted to ICU and no SARI related deaths were reported. The
weekly SARI incidence was 6.7 per 100 000 population. The SARI related influenza incidence was 0.9
per 100 000 population.

 Respiratory pathogen surveillance

viruses. In addition, 39 SARI specimens were tested, eight were positive for influenza viruses. For
details, see Table 3 and Figures 5 and 6.
