Worst ever flu year for NSW

0:00

New South Wales has recorded its worst year for flu, with the number of confirmed cases already surpassing the 2016 total.

A NSW Health report confirms 35,727 cases of the flu have been detected in NSW residents so far in 2017, compared to last year's 12 month record of 35,538.

With 12,724 flu cases registered already in August – traditionally the worst month for influenza – the NSW opposition is accusing the Berejiklian government of being unprepared.

“The last thing the NSW health and hospital system needs is to see hundreds of extra patients pouring into emergency departments with preventable flu symptoms," Labor health spokesman Walt Secord said in a statement on Wednesday.

Particularly vulnerable

It's certainly not common but it's more than possible to be hit with the flu twice this year as a mix of influenza strains circulates the country.

Dr Vicky Sheppeard, Director of Communicable Diseases at NSW Health, said people with flu symptoms should avoid passing on their infection to friends and family, especially to those who may be particularly vulnerable, like elderly people and pregnant women.

“Covering coughs and sneezes with a tissue, disposing of used tissues and washing hands thoroughly and often are simple precautions people can take from spreading flu,” she said.

“We are seeing high levels of both influenza A and B strains circulating in the community, which places vulnerable people at high risk of catching the influenza and developing severe complications. There have also been 150 outbreaks reported in aged care facilities since the start of the year.”

'Significant increase in cases'

General practitioner Natalie Caristo works on the frontline of the yearly influenza outbreak.

She says 2017 has been a bad year for the number of cases seen so far at the Abbotsford Medical Practice in Sydney's inner west, where she works.

"There's definitely been a significant increase in the number of cases of the flu recently. This year's been quite severe, and, particularly, we've been seeing both Influenza A and Influenza B spiking at the same time. And the type of illness that we've been seeing has been quite severe, particularly hitting the more vulnerable members of the population."

The rush of flu-infected patients at Dr Caristo's practice is part of a widespread surge in cases.

New South Wales Health Pathology's senior medical virologist, Professor Bill Rawlinson, says the potentially unprecedented spike began four weeks ago.

"They've come up very quickly. So we haven't had many cases. Then, about mid-July, all of a sudden, we saw a really big uptick in the number of cases. We're still midway through. We're really at the peak of flu at the moment.

“And what we would normally see is, over the next two to three weeks, falling numbers but continuing flu. At the moment, it does appear that the rise has been higher than in previous years."

Over 75,000 infections confirmed

In the past 10 years, the number of lab-confirmed flu cases has gone through peaks and troughs.

From little over 10,000 in 2007, it climbed to more than 90,000 last year.

The highest number of cases in a year so far was in 2015, with more than 100,000 recorded.

So far this year, just over 75,000 infections have been confirmed, easily above the numbers at the same stage that year.

Risk factors

The Royal Australian College of General Practitioners' Dr Bastian Seidel says the lab-confirmed cases are just a small part of the story.

"Every year, we are seeing 300,000 Australians who do contract the flu. 18,000 of them are going to be admitted to hospital because of complications and, unfortunately, 3,000 Australians will die from complications of influenza."

Professor Rawlinson, the virologist, says, while no-one is immune from contracting the flu, some people are more likely to have a serious reaction.

"People with diabetes, people with chronic heart or lung disease, people who've received transplants, Aboriginal and Torres Strait Islanders who are, particularly, over the age of 50, as well as elderly people – and they're defined as over 65 – those groups are really at risk of more severe illness."

Prevention

Dr Seidel, from the Royal Australian College of General Practitioners, says the focus should be on prevention.

He suggests the government should make influenza vaccinations free for every Australian.

"You're asking me whether we should be spending money to prevent influenza in the first place? Absolutely. It would be key to vaccinate everyone from the age of six months onwards – not only the ones who are at risk, because everybody is going to be at risk. You know, influenza doesn't ask any questions. It can affect everybody."

Dr Seidel also has a message for the public: It is never too late to be vaccinated.
