Experts urge RSV awareness for older adults before winter

As the chill of winter approaches, most of us are well-versed in the annual warnings about the flu and, more recently, COVID-19. 

But there’s another respiratory virus quietly making its rounds—and it’s not just a concern for little ones. 

Experts are sounding the alarm about RSV (respiratory syncytial virus), a highly contagious bug that can be just as dangerous for older adults as it is for babies.

What is RSV and why should seniors care?

RSV is a common respiratory virus that most people associate with infants and toddlers. In fact, by the age of two, nearly every child will have had RSV at least once. 

But here’s the kicker: RSV doesn’t just target the young. It can cause severe illness in older adults, especially those over 60, and those with underlying health conditions like asthma, COPD, or heart disease.

Professor Lucy Morgan, a leading Sydney respiratory physician and Chair of the Lung Foundation, warns: ‘We know older adults are familiar with influenza—but less aware of RSV and the serious health challenges this infectious respiratory virus can cause. We really want older Australians, particularly those caring for grandchildren, to become much more informed and aware of RSV. They need to know about their risk and not assume it’s just a problem in babies.’

The hidden dangers for older adults

While RSV often starts with mild symptoms—think cough, runny nose, tiredness, and congestion—it can quickly escalate in older adults. The virus can lead to pneumonia, hospitalisation, and, in some cases, long-term health complications or even loss of independence.

Here are some sobering facts about RSV in older adults: those who are hospitalised with the virus may spend twice as long in the hospital compared to children under five. 

Tragically, fatalities from RSV are nearly four times higher in older adults than in young children. 

Even after being discharged, many seniors face a slow and difficult recovery, with some never regaining their previous level of health or independence.

Associate Professor and Senior Geriatrician Michael Woodward explains: ‘The impact of RSV can be very serious for older Australians who may struggle to regain their health and strength after the virus has cleared. 

Unfortunately, some may have significant delays in regaining their former health and independence after RSV.’

Who’s most at risk?

While anyone can catch RSV, certain groups are more vulnerable:

• People aged 60 and over 
• Those with chronic lung or heart conditions (like asthma, COPD, or heart failure) 
• Individuals with weakened immune systems 
• Grandparents and carers who spend time with young children (who are often the source of infection)

Clinical Professor John Blakey, Consultant Respiratory Physician and Medical Advisor to Asthma Australia, adds: ‘Older adults with existing heart or lung disease are at higher risk of being admitted with RSV: they are 5 to 10 times more likely to end up in hospital. People with conditions like asthma and COPD therefore need to be particularly aware of RSV and how to minimise their risk.’

How does RSV spread?

RSV is highly contagious and can survive on hard surfaces for up to six hours. It spreads easily through droplets from coughs and sneezes, and by touching contaminated surfaces—think doorknobs, handrails, or even your grandchild’s favourite toy. 

Infected individuals can remain contagious for up to 10 days, making it easy for the virus to move through families and communities.

What are the symptoms?

RSV symptoms can be very similar to those of the flu or COVID-19, making it difficult to distinguish between them. Common symptoms include cough, headache, tiredness, runny nose, and nasal congestion. 

If you experience any of these symptoms, especially if you have underlying health conditions, it’s important to seek medical advice promptly.

Why is RSV on the rise?

Australia only began tracking RSV cases under the Notifiable Diseases Surveillance System in 2021, but the numbers are already concerning. 

Last year, there were over 32,000 reported RSV cases in older Australians—more than half the number of influenza cases. 

Experts believe the true number is likely much higher, as many cases go unreported or are mistaken for other respiratory illnesses.

As we head into winter, it’s more important than ever to be vigilant about all respiratory viruses—not just the flu or COVID-19. RSV is a real threat to older Australians, but with awareness and a few simple precautions, you can reduce your risk.
