Why are the elderly at a higher risk of infection?

1. A. They have strong immune systems

2. B. They are rarely hospitalized

3. C. They are always well-nourished

4. D. They may have limited mobility

The correct answer is: D. They may have limited mobility

The elderly are at a higher risk of infection primarily due to factors associated with aging, including limited mobility. As people age, they may experience physical limitations that hinder their ability to perform daily activities, including maintaining personal hygiene and getting adequate exercise. Limited mobility can lead to prolonged periods of inactivity and increased vulnerability to health issues, including infections. In addition to mobility issues, other physiological changes that occur with age, such as a decline in immune function, can also contribute to a higher susceptibility to infections. Consequently, individuals who are less active may not only find it challenging to stay healthy but also may develop complications that can predispose them to infections, such as pressure sores, which can become gateways for bacteria. Thus, recognizing the link between limited mobility and increased infection risk is crucial in caring for the elderly and implementing preventive measures to help mitigate this risk.
