Health officials are warning of a late and possibly important peak in influenza cases across New Zealand, with illness rates currently rising in the south.
Typically running from May to October, the flu season peaked earlier in recent years, around June or July following the COVID-19 pandemic. however, FluTracking data shows a steady increase in reported influenza-like illness since may, continuing into late August. while current weekly rates remain lower then the peaks observed between 2022 and 2024, the delayed surge is prompting concern among health experts.
This year’s increase is attributed to a combination of viruses, including influenza A [H1N1] and B strains, a prolonged Respiratory Syncytial Virus (RSV) season, and ongoing COVID-19 transmission. While influenza viruses can disproportionately affect young peopel, health officials caution that even healthy adults are at risk of serious illness.
Laboratory testing confirms that both influenza and RSV are contributing to the spread of respiratory illness. Fortunately, this year’s seasonal influenza vaccine is well-matched to the circulating strains and is expected to provide strong protection.
