When a grandchild catches the flu, everyone knows it: high fever, cough, runny nose and a kid who wants to stay in bed. With grandparents, it can play out very differently. Influenza in an older person often hides behind tiredness, a vague "he's just not himself today" or a plate left half full. That's why, this season, the most useful person isn't always the patient but the family member who lives with them and knows what a normal day looks like.
This guide from the clinic's medical team is written for the sons, daughters, grandkids and caregivers in Spring Branch and across Houston who share a home with someone over 65.
Why the flu looks different after 65
As we age, the immune system reacts more slowly. That has two practical consequences worth keeping in mind:
- Fever may be mild or missing altogether. A grandparent with influenza can read 99 °F on the thermometer and still be quite sick. Don't let the thermometer be your only guide.
- Complications set in more easily. The CDC lists people 65 and older among the groups at highest risk of serious flu complications, such as pneumonia, dehydration or a flare-up of conditions they already live with.
On top of that, plenty of older adults simply don't complain. They say "it's nothing" so nobody worries, or because they'd rather not leave the house for a visit. A family's eye makes up for that silence.
What relatives notice before the grandparent does
This table sums up changes worth taking seriously during respiratory virus season:
| What you see at home | Why it matters | What to do |
|---|---|---|
| More confused, disoriented or drowsy than usual | Can point to infection, low oxygen or dehydration | If the change is sudden, call 911 |
| Stopped eating or barely drinking | Dehydration sets in fast at that age | Offer frequent sips and bring them in if it doesn't improve that day |
| Few bathroom trips, or very dark urine | Another clue that fluids are running low | Write it down and mention it at the visit |
| A fall, unsteady walking or trouble getting up alone | Weakness from the infection raises fall risk | Don't let them walk unassisted; get care |
| Breathing faster or getting winded while talking | The infection may have reached the lungs | If they're short of breath, it's an emergency |
| Got better, then the fever returns or the cough worsens days later | Could be a complication such as pneumonia | Don't wait: bring them in, or call 911 if breathing is hard |
A simple log for the sick days
When several relatives take turns caregiving, details slip through the cracks. A sheet taped to the fridge or a shared note on everyone's phone fixes that. Write down, at least twice a day:
- Temperature, with the time you took it.
- How much they drank: glasses of water, broth, oral rehydration drinks.
- How many bathroom trips and the color of the urine.
- What they ate, even if it was just a few bites.
- Which medicines they took and when, including the everyday ones.
- Their mood and alertness: whether they recognized you, knew what day it was, talked the way they usually do.
With that log in hand, the visit moves faster and the medical team can compare real data instead of "I think yesterday was better."
Don't let everyday medicines quietly stop
Many grandparents take pills for blood pressure, blood sugar, the heart or cholesterol. When the flu hits, it's common for them to skip those pills because they aren't eating or feel lousy, or for a relative to pick up a cough syrup without checking whether it clashes with what they already take.
A few practical rules:
- Don't stop a regular medicine without asking first.
- Before giving an over-the-counter cold remedy, read the label and ask: some decongestants aren't a good fit for people with high blood pressure.
- If they have diabetes and aren't eating, ask how to handle their medicine on those days instead of guessing.
- Bring a bag with the boxes of everything they take to the visit.
If your grandparent already has their diabetes, blood pressure or cholesterol care with us, let the front desk know they have the flu so the team can look at the whole picture together.
Why an early visit makes sense
With older adults, "let's see if it passes" isn't a good plan. Flu has antiviral medicines that work best when started within the first two days of symptoms, and people 65 and older are exactly the group where the medical team weighs that option most carefully.
Our team swabs the nose for flu and COVID rapid testing, and you'll hear which virus showed up within minutes, before your grandparent leaves the exam room. The team also checks temperature and vital signs and listens to the lungs to see whether something more than a virus is going on. Knowing which virus it is helps decide on treatment and protect everyone else in the house.
To make the trip easier on your grandparent:
- Dress them in comfortable clothes with a light jacket: going from the outdoor heat into air conditioning wears them out.
- Have the person who's been caring for them come along and bring the log.
- Bring their glasses and hearing aid if they use one, so they can follow the instructions.
When not to wait: call 911
Some signs mean your grandparent needs an emergency room, not a clinic. Call 911 if you notice:
- Trouble breathing or shortness of breath even while sitting.
- Chest tightness or pain that keeps going even after they rest.
- Bluish or purple lips, face or fingernails.
- New confusion, being hard to wake, or not responding the way they normally do.
- Seizures.
- No urine all day, or weakness so severe they can't stand up.
- A chronic condition that suddenly gets worse, such as blood sugar running very high or very low.
Recovery needs watching too
In an older person, the flu isn't over when the fever breaks. Fatigue lasting longer than it would in a younger adult is normal, but keep an eye on a few things over the following weeks:
- They gradually get back to walking and eating the way they did before.
- The cough slowly fades instead of getting stronger or bringing up colored phlegm.
- The fever doesn't come back after several days without it.
If any of these goes off track, bring them back in for another look.
Prevention at home: the shot and a few habits
The flu vaccine is updated every season because the virus changes from year to year, and it matters most for people over 65 and for anyone living with an older adult. Vaccinating your grandparent helps; vaccinating the people who share their home closes one more door to infection. The injected flu shot has no live virus, so it can't give anyone the flu.
Simple habits at home help as well:
- Wash hands when coming home from errands, work or school.
- Have the sick relative wear a mask around the grandparent and, if possible, sleep in another room.
- Wipe down door handles, remotes and phones that everyone touches.
