Kiwis hit by severe flu virus
New Zealanders have been hit in increasing numbers by the A(H3N2)-like influenza virus in recent weeks.
Latest ESR general practice sentinel surveillance data (week to June 10) shows a national consultation rate of 18.4 per
100,000 (69 ILI or influenza-like-illness consultations).
Although this level is still considered to be below normal seasonal activity, there have been noticeable ILI spikes in
Auckland (40.9 per 100,000) and South Canterbury (51.9 per 100,000) regions where the influenza strain A(H3N2) has been
predominant.
Virus expert and National Influenza Specialist Group (NISG) spokesperson, Dr Lance Jennings says the predominance of the
H3N2 virus is a concern because infections with this virus can be particularly severe for the elderly and those with an
ongoing medical condition.
“A major outbreak of H3N2 would cause a surge in hospital admissions and deaths. It’s not too late, however, for
eligible people to get a free flu vaccination which covers three strains currently in circulation in the southern
hemisphere, including H3N2,” says virus expert and National Influenza Specialist Group (NISG) spokesperson, Dr Lance
Jennings.
”Vaccination is the best way to protect yourself from influenza. We know that some people just ‘don’t get around to it’
but I would strongly urge them to act now if they want to avoid being seriously ill or ending up in hospital during
their busy winter period.
“When you start seeing other people getting the ‘flu’ it’s almost too late to protect yourself. It can take up to two
weeks to develop immunity from the time of vaccination. So people need to book in with their doctor or nurse today.”
Flu immunisation is free for New Zealanders at high risk of more severe disease and complications – pregnant women,
people aged 65 and over, and anyone with ongoing health conditions such as heart disease, strokes, diabetes, respiratory
disease (including asthma), kidney disease and most cancers. Canterbury residents also qualify for free vaccination if
they are aged between 6 months and 18 years old.
Around 940,000 New Zealanders have already had a flu vaccination this year, about the same number as at this time in
2011.
It’s estimated more than 400 people die each year in New Zealand because influenza can make other conditions, such as
breathing or heart problems, even worse.
Influenza vaccine is only free for eligible groups from a doctor or nurse until July 31. Vaccine is available to other
people for a small charge or provided free by some employers in workplace schemes. Immunisation is available, but not
free, for healthy children six months and over and adults.
“We’re also seeing other respiratory viral infections, including common colds, in the community and it’s important
people don’t confuse them with actual influenza. They may have some similar symptoms but they’re not the same thing.”
Influenza is usually characterized by a sudden onset of illness, high fever, headache, a dry cough and usually lasts
7-10 days.
Influenza immunisation cannot give you the flu because it does not contain live viruses. There can be side effects, and
these usually disappear within 1-2 days without treatment.
NISG says that as well as getting a flu vaccination there are other ways you can protect yourself and your family/whanau
from flu including:
Wash and dry your hands often
Stay away from people who are sick
Stay away from work or school if you’re unwell
Cover your coughs and sneezes.
