Why the Flu Is Riskier After 65
Immune defenses weaken with age, so older adults have a harder time fighting infections. The CDC reports that in recent years, roughly 70% to 85% of seasonal flu-related deaths and 50% to 70% of flu-related hospitalizations occurred in people 65 and older.
The flu can also worsen existing conditions such as heart disease, lung disease (COPD, asthma) and diabetes, and it can lead to pneumonia and dehydration. That is why “wait and see” is not the best plan for this age group.
Flu Symptoms in Older Adults
Classic flu symptoms include:
- Fever or feeling feverish, with chills
- Cough and sore throat
- Runny or stuffy nose
- Muscle or body aches and headache
- Fatigue
In older adults, the flu can also look different. Fever may be mild or absent, and the first sign may be a change in how the person acts or functions.
| What you may notice | Why it matters |
|---|---|
| No fever or only a low fever | A normal temperature does not rule out flu |
| New confusion, drowsiness or unusual behavior | Can signal a serious infection or dehydration |
| Loss of appetite or not drinking | Raises the risk of dehydration |
| Unusual weakness, falls or unsteadiness | Can be the main sign of illness in seniors |
| Worsening of a chronic condition (breathing, blood sugar, heart symptoms) | Flu can trigger flare-ups |
If a parent, spouse or neighbor “just isn’t themselves,” take it seriously, even without a fever.
When to Seek Medical Care: A Simple Guide
Call or visit a provider the same day if you are 65+ and have flu symptoms
The CDC recommends that adults 65 and older call a healthcare provider right away when flu symptoms start. Antiviral drugs work best when started within about two days of symptoms. Early treatment may make the illness milder and shorter and may help prevent complications. Being seen early also lets a provider check for other causes, such as RSV or COVID-19.
Get evaluated the same day if you have:
- Any flu-like symptoms and you are 65 or older
- Heart disease, lung disease, diabetes, kidney disease or a weakened immune system, at any age
- A fever, cough or weakness that is not improving after a couple of days
- Poor appetite, trouble drinking fluids, or signs of dehydration (dry mouth, very dark urine, dizziness when standing)
- Symptoms in an older adult who lives alone or in a care facility
Go to the ER or call 911 for emergency warning signs
The CDC lists these emergency warning signs in adults:
- Difficulty breathing or shortness of breath
- Pain or pressure in the chest or abdomen
- Sudden dizziness
- Confusion
- Severe or persistent vomiting
Also seek emergency care for bluish lips, being unable to stay awake, or symptoms that improve and then return with a worse fever or cough. That pattern can signal pneumonia or another complication.
Where to go: at a glance
| Situation | Best next step |
|---|---|
| Mild symptoms, 65+, drinking fluids, thinking clearly | Same-day visit to a walk-in clinic or your provider |
| Symptoms lasting or worsening after 2–3 days, or you have a chronic condition | Urgent care visit today |
| Trouble breathing, chest pain, confusion, sudden dizziness, persistent vomiting | ER or 911 |

How to Care for an Older Adult With the Flu at Home
If a provider says home care is appropriate:
- Fluids: Encourage frequent sips of water, broth or electrolyte drinks
- Rest: Allow extra sleep and avoid overexertion
- Medications: Take prescribed antivirals exactly as directed, and check with a provider or pharmacist before combining over-the-counter cold and flu products with other medicines
- Check in: Call or visit often if the person lives alone
- Watch for change: New confusion, trouble breathing or worsening cough means get help right away
Prevention: Flu Shots for Adults 65+
An annual flu vaccine is the best protection against flu and serious complications. The CDC and ACIP preferentially recommend higher-dose or adjuvanted flu vaccines over standard-dose vaccines for people 65 and older. If one of those is not available, a standard-dose inactivated vaccine is better than skipping the shot. Adults 50 and older should also ask about pneumococcal vaccination, since pneumonia is a serious flu-related complication.

FAQs
What are the first signs of the flu in older adults?
Common early signs are fatigue, body aches, cough, sore throat and chills. In older adults, the first sign may be unusual weakness, loss of appetite or confusion, sometimes without a fever.
Can an older adult have the flu without a fever?
Yes. A mild or absent fever is more common in older adults, so a normal temperature does not rule out the flu.
When should a senior see a doctor for the flu?
The CDC advises adults 65 and older to call a healthcare provider right away when flu symptoms begin, since antivirals work best when started early.
When is the flu an emergency in older adults?
Seek emergency care for difficulty breathing, chest or abdominal pain or pressure, sudden dizziness, confusion, or severe or persistent vomiting.
Can urgent care treat the flu in older adults?
Yes, for non-life-threatening illness. A provider can evaluate symptoms, test when appropriate, discuss antiviral treatment and advise on home care. Emergency warning signs need the ER. See our urgent care services.
How long does the flu last in older adults?
Many people feel better within one to two weeks, but cough and fatigue can linger. Symptoms that improve and then worsen, or that last longer than expected, should be evaluated.
What is the difference between a cold and the flu in seniors?
Flu usually comes on suddenly with more body aches, fatigue and fever. Colds are typically milder and centered on the nose and throat. Because the two can overlap, older adults with new respiratory symptoms should get checked.
Do I need an appointment?
No. Sahara West welcomes walk-ins during clinic hours, and you can also call ahead or book online.
Is the flu shot still worth getting if I already feel sick?
Not while you’re acutely ill. Get evaluated first, then ask your provider when to get vaccinated.
The Bottom Line
For adults 65 and older, flu symptoms deserve prompt attention. Call a provider early, know the emergency warning signs, and don’t dismiss confusion or weakness just because there’s no fever.
