Increasing numbers of Kiwis are being affected by a flu strain resembling one that caused an epidemic in 1996.
Latest surveillance data show a spike in general practice consultations for influenza-like illness in Auckland and South Canterbury where the A(H3N2)-like virus has been predominant, according to a media release from the National Influenza Specialist Group (NISG).
An H3N2 strain of the influenza virus caused an epidemic in 1996 that saw patients waiting in hospital corridors as hospitals couldn't cope (New Zealand Doctor, 11 February 2009).
NISG spokesperson Lance Jennings says in the press release H3N2 infections are a concern because they can be particularly severe in the elderly and in those with underlying medical conditions.
A major outbreak of H3N2 would cause a surge in hospital admissions and deaths, Dr Jennings says.
Flu vaccine covers A(H3N2)-like strain
Free vaccination covering all three flu strains endemic in New Zealand, including A(H3N2), is available to eligible people until 31 July.
Eligible groups include pregnant women, people aged 65 and over, and people with pre-existing conditions such as heart disease and diabetes.
