Which factor can increase the risk of infection in patients?

Age and general health condition significantly influence a patient's susceptibility to infections. Older adults may have a less robust immune response due to natural aging processes, making them more vulnerable to infections. Additionally, individuals with chronic health issues or compromised immune systems—such as those with diabetes, cancer, or autoimmune diseases—are at heightened risk. This is because these conditions can impair the body's ability to fight off pathogens. Conversely, factors like proper nutrition, regular physical activity, and good hydration are known to strengthen the immune system and support overall health, thereby reducing the risk of infection. Understanding the interplay between age, health status, and infection risk is essential for effective infection prevention strategies.
