Fever is a temporary rise in body temperature, usually because the body is fighting an infection. In older adults, fever can sometimes be less obvious or lower, but it is still an important sign that something might be wrong. It is one of the body's natural defense mechanisms.
Key facts
Yes, fever is quite common in older adults, especially when they have an infection. However, it can be easy to miss because the temperature rise might be small and other symptoms like confusion may be mistaken for dementia or aging.
Fever can affect anyone, but it is especially important in people aged 65 and older because their immune systems are often weaker, and they may have other health conditions that increase risk of complications.
The doctor will take the person’s temperature, ask about symptoms and medical history, and perform a physical examination. They will look for signs of infection and may ask about recent travel, medications, and any other health changes.
Treatment focuses on finding and addressing the underlying cause of the fever—usually an infection—and helping the body recover. In many cases, fever can be managed at home with rest and fluids, but if the cause is a bacterial infection, antibiotics may be prescribed. The goal is to reduce discomfort and prevent complications.
During a fever, the main priority is rest and recovery. Monitor your temperature and other symptoms closely. Keep a record to share with your doctor. Stay in touch with family or friends to get help with daily tasks if needed. Once the fever resolves, gradually return to normal activities as your strength allows.
While you have a fever, eat light, easy-to-digest foods like soups, broths, and toast if you have an appetite. Drink plenty of fluids to stay hydrated. Gentle stretching or short walks can be resumed when you feel better, but avoid vigorous exercise until the fever is gone and you have regained strength.
Not all fevers can be prevented, but the risk of infections can be reduced with good hygiene, staying up to date on vaccinations, and avoiding close contact with sick people. Keeping chronic conditions well-managed also helps your immune system stay strong.
Vaccines are recommended for older adults to prevent certain infections that cause fever. These include the flu vaccine, pneumonia vaccine, and shingles vaccine. Ask your doctor which vaccines are right for you.
There are no routine screening tests specifically for fever, but regular check-ups can help detect and manage underlying health conditions that increase infection risk. If you have symptoms, seek medical advice early.
With timely care, most older adults recover fully from a fever without long-term problems. Early treatment of the underlying cause, especially infections, greatly improves outcomes. It is important to act quickly if you notice changes in mental state or other warning signs. Most fevers are treatable, and your healthcare team will support you to get back to your usual health.

The doctor will work to find the cause of the fever and may start treatment quickly, especially if an infection is suspected. You may need to go to the hospital if the fever is high or if there are signs of a serious infection. The doctor will monitor vital signs and may recommend staying in for observation or treatment.
If a bacterial infection is found, your doctor will prescribe antibiotics to take as directed. For viral infections, antiviral medications may be considered in certain cases. Never take leftover antibiotics or share them with others. If the fever is very high or causing severe symptoms, the doctor may recommend medication to bring the fever down—always use as directed and ask your pharmacist about options. In hospital, you may receive intravenous fluids or other supportive treatments.
Surgery is rarely needed for fever itself. However, if an infection has caused an abscess (a collection of pus) that needs draining, a small surgical procedure may be required. This is not common for most fevers.
Having a fever can be stressful, especially if you feel confused or anxious. It is normal to feel worried. Talk to your doctor or a trusted person about your concerns. If confusion persists after the fever goes away, seek medical advice. For mental health crisis, contact a crisis support line immediately.
