An older person is at a higher risk for infection because of changes in:

Older adults experience a natural decline in immune function as part of the aging process, making them more susceptible to infections. This decline can be attributed to several factors, including a decrease in the production of immune cells, reduced response rates of antibodies, and the presence of chronic health conditions that can compromise immune integrity. As the immune system weakens, older individuals may not respond as effectively to pathogens, increasing their risk for infections.

While dietary habits, physical activity levels, and living arrangements can also impact health and wellness, the direct link between aging and weakened immune response is the primary concern when it comes to elevated infection risk. Understanding this connection is crucial for caregivers and healthcare professionals when planning care for the elderly. They should prioritize measures to bolster the immune system and reduce infection risk through vaccinations, nutrition, and appropriate health monitoring.
