What does influenza mean in older adults?

In older adults, influenza is a respiratory viral infection that can cause significant illness and worsen existing health conditions. Fever may be absent or less pronounced, while weakness, confusion, reduced appetite, or a decline in usual function can be noticeable.

Influenza commonly causes a sudden cough, sore throat, headache, chills, tiredness, and muscle aches. Older adults may recover more slowly and may be more vulnerable to dehydration, breathing problems, or complications such as pneumonia. Heart, lung, kidney, or immune conditions can make an infection harder to manage. A new change in alertness or ability to walk deserves attention even without a high temperature.

Contact a clinician promptly if influenza is suspected, especially when symptoms began recently or the person has long-term medical conditions. Rest, take fluids in small frequent amounts, and use only medicines that fit the person’s prescriptions and health history. Keep the person away from close contact while unwell, improve ventilation, and wash hands after coughing or helping with care. Monitor breathing, alertness, urine output, and ability to eat and drink.

Seek urgent medical help for trouble breathing, chest pain, blue or grey lips, fainting, severe weakness, new confusion, inability to keep fluids down, or very little urine. Urgent assessment is also needed if symptoms improve and then return with worse cough, feverishness, or breathing difficulty, because this pattern can signal a complication.

Ask whether antiviral treatment is appropriate, which regular medicines should continue, how to manage fluids and fever, and which changes should trigger same-day review. Bring a list of medical conditions and medicines, including non-prescription products.
