First flu for two years: cases on the rise

After two years with no cases - flu is back - and hitting hard in some places. As of the eight of May there were 58 reported influenza positives cases, although the real number is likely much higher, as only people seeking hospital or GP care are tested. Dunedin is particularly hit hard with 44 cases the week before last. Around 1.28 million doses of flu vaccines have been distributed around the country. Director of the National Influenza Centre virologist Dr Sue Huang is with me now.
