INFLUENZA WEEKLY UPDATE
2013/19: 5?12 May 2013

The national influenza surveillance system in New Zealand is an essential public health component for assessing and implementing strategies to control influenza. This report summarises the data collected from sentinel general practice (GP) surveillance and non-sentinel surveillance for week 19 (5?12 May 2013).

Summary
 ILI through sentinel surveillance was reported from 16 out of 20 District Health Boards (DHB) with a national consultation rate of 6.1 per 100 000 (21 ILI consultations).
 A total of 149 swabs were received from sentinel (17) and non-sentinel (132) surveillance.
 7 viruses were identified: B (not typed) (3), A(H3N2) (2), A/Perth/16/2009 (H3N2) (1), and A (not sub-typed) (1).

INFLUENZA-LIKE ILLNESS SURVEILLANCE
In the past week, a total of 21 consultations for influenza-like illness were reported from 62 general practices in 16 out of 20 DHBs. This gives a weekly consultation rate of 6.1 per 100 000 patient population. Figure 1 shows the weekly national consultation rates for 2011, 2012 seasons, and 2013 so far. The current rate of influenza-like illness is below the baseline.
