Who is most likely to be immunocompromised?

An elderly individual with chronic illness is most likely to be immunocompromised due to several factors. As people age, their immune systems naturally become less effective, which can result in a decreased ability to fight off infections and illnesses. Additionally, chronic illnesses such as diabetes, cancer, or heart disease further weaken the immune system, making this population more susceptible to infections and complications.

In contrast, a healthy adult generally has a robust immune response, which helps them fight off infections effectively. A toddler with good nutrition is typically in a developmental stage where their immune system is still learning to respond to pathogens, but good nutrition supports strong immune function. Similarly, a physically active adolescent is usually in a stage of life characterized by good overall health, higher metabolism, and physical resilience, contributing to a strong immune system. These factors enhance their ability to maintain a healthy immune response compared to an elderly individual with chronic health issues.
