6 Common Infections in the Elderly


At 7 Day Home Care, we emphasize the critical importance of early detection of common infections in the elderly, as timely identification and treatment can significantly improve health outcomes and prevent complications. Older adults are more susceptible to infections such as urinary tract infections, respiratory infections, and skin infections due to age-related changes in their immune system, coexisting chronic conditions, and decreased physiological reserves. Early signs of infection, often subtle or atypical, can include confusion, fatigue, or a sudden decline in functional ability, which may be mistakenly attributed to aging. By promptly recognizing these early indicators, our skilled caregivers can facilitate immediate medical intervention, thereby reducing the risk of severe illness, hospitalization, and further decline in health. Our proactive approach ensures that our elderly clients maintain their quality of life, safety, and overall well-being, highlighting the indispensable role of vigilance and early detection in geriatric care.

Knowledge and Awareness of Common Infections Can

Help Ensure Early Detection and Timely Treatment


As we age, our immune system weakens, making seniors more susceptible to various infections. Proper knowledge and awareness of common infections are crucial for the elderly and their loved ones to ensure early detection and timely treatment. This article identifies 6 common infections that affect the elderly, along with some of their signs and symptoms to be cognizant of over the long term.


1. Urinary Tract Infections (UTIs) and the Elderly

Urinary tract infections are prevalent among the elderly, affecting both men and women. According to the Centers for Disease Control and Prevention (CDC), UTIs account for approximately 8.1 million visits to healthcare providers each year in the United States, with the elderly being at higher risk.


Signs and Symptoms of UTI:

  • Frequent urge to urinate
  • Pain or burning sensation during urination
  • Cloudy or bloody urine
  • Lower abdominal pain or discomfort


2. Respiratory Infections with the Elderly

Respiratory infections, such as pneumonia and influenza, can be severe for older adults. Pneumonia is a leading cause of hospitalization and mortality among the elderly. The American Lung Association reports that adults aged 65 and older accounted for around 49,000 pneumonia-related deaths in 2018.


Signs and Symptoms of Pneumonia:

  • Persistent cough with green or yellow mucus
  • Fever and chills
  • Shortness of breath
  • Chest pain when breathing or coughing


3. Skin Infections and the Elderly

The aging process leads to changes in the skin, making it more susceptible to infections. Skin infections, like cellulitis, can arise from minor injuries or compromised skin. The World Health Organization (WHO) estimates that cellulitis affects approximately 14-17% of elderly individuals globally.


Signs and Symptoms of Skin Infections:

  • Red, swollen, and tender skin
  • Warmth around the affected area
  • Fever and chills


4. Gastrointestinal Infections

Gastrointestinal infections, particularly caused by norovirus and Clostridium difficile, are a significant concern for the elderly due to their potential for dehydration and severe complications. The CDC estimates that norovirus leads to 56,000-71,000 hospitalizations and 570-800 deaths among adults aged 65 years and older annually.


Signs and Symptoms of Norovirus:

  • Nausea and vomiting
  • Diarrhea
  • Stomach cramps
  • Low-grade fever


5. Influenza

Influenza, commonly known as the flu, poses a serious threat to the elderly. The CDC reports that the majority of influenza-related hospitalizations and deaths occur in individuals aged 65 years and older. In the 2019-2020 flu season, an estimated 52% of hospitalizations due to influenza were in this age group.


Signs and Symptoms of Influenza:

  • High fever
  • Body aches and fatigue
  • Sore throat
  • Headache


6. Sepsis

Sepsis is a life-threatening response to infection that can quickly escalate in the elderly. According to the Sepsis Alliance, sepsis affects more than 1.7 million adults in the U.S. each year, with approximately 270,000 resulting deaths. Older adults are more likely to develop sepsis and have a higher risk of mortality.


Signs and Symptoms of Sepsis:

  • Fever or low body temperature
  • Rapid heart rate
  • Confusion or disorientation
  • Shortness of breath


Recognizing the Signs of Infection in the Elderly


Early detection of infection is crucial for prompt treatment. Family members and caregivers should be vigilant in identifying signs that may indicate infection in elderly individuals under their care. Some general symptoms to look out for include:


  • Changes in behavior or mental status
  • Loss of appetite or sudden weight loss
  • Fatigue or weakness
  • Increased falls or difficulty walking
  • Worsening chronic health conditions
