Influenza is more than a winter inconvenience for older adults. It is one of the illnesses most likely to send someone to the hospital and leave them weaker than they were before.
Why the risk is higher after 65
Older adults account for about 70% to 85% of flu-related deaths and 50% to 70% of flu-related hospitalizations in the United States. Even after recovery, some people never fully regain the strength they had before the illness. The weeks after influenza can also raise the risk of heart problems.
The immune system responds less vigorously with age. That is why the CDC recommends that people 65 and older receive a higher-dose or adjuvanted flu vaccine rather than a standard dose.
What actually prevents illness
- Get the recommended flu vaccine every year, ideally before flu activity rises.
- Wash hands with soap and water for at least 20 seconds, especially before meals.
- Avoid close contact with people who are sick when it is possible to do so.
- Stay home when fever, cough, or unusual fatigue appears.
- Ask the clinician promptly if symptoms start—treatment is more useful early.
In older adults, influenza may look like confusion, weakness, or a fall rather than a classic fever and cough. A sudden change is a reason to call, not to wait it out.
Support during flu season
A Care Partner can help someone get to a vaccination appointment, keep the home clean, and notice the first signs of illness. They can also help with meals, fluids, and rest if the person does become sick—so a treatable illness does not turn into a crisis at home.
The goal is not to hide from winter. The goal is to lower the chance of a preventable hospitalization and protect the independence the person has worked to keep.
