Some of the more frequently-occurring infections that caregivers of seniors need to be especially careful about:

Bacterial Pneumonia

While the classic symptoms of pneumonia like cough, chills, fever, etc. are less common in seniors, conditions like delirium or confusion may be indicative.

Antibiotic treatment is the recommended course of action for bacterial pneumonia and doctors may even prescribe a pneumococcal vaccine for effective resolution in residents of nursing homes.

Elderly influenza

The combination of influenza and pneumonia is one of the leading causes of fatalities in America and senior citizens account for 90% of such deaths.

According to, often, the occurrence of flu is not easily detected in seniors because the classic symptoms may be missing.

Confirmation of influenza may require an Elisa test to be conducted. While common symptoms like fever, cough, chills, etc. manifest typically, there might be other symptoms in seniors that should not be ignored.

Caregivers of the elderly need to stay alert to unusual pain, lesions or itching that may need treatment. While shingles is easily preventable with the help of a vaccine, other skin infections are treatable. Practicing good hygiene helps to keep skin infections at bay.

Gastrointestinal infections

Seniors tend to be at a greater risk of developing gastrointestinal infections due to changes in digestive ability and gastrointestinal flora.

Seniors may get nausea, fever, and pain in the upper abdomen as well as gastritis due to Helicobacter pylori while Clostridium difficile, a common infection that causes diarrhea due to the suppression of healthy gastrointestinal flora by antibiotics. Both of these conditions are very common to residents of long-term care facilities.

A combination of drugs is used to treat H. pylori while C. difficile is treated by identifying and stopping the use of the antibiotic that caused the problem.


Keeping the elderly healthy is a continuing process and caregivers have to stay informed and alert all the time to prevent complications. Most of the infections can be prevented or effectively treated to ensure seniors have a better quality of life.
