Which risk factor increases the likelihood of infection in patients?

A compromised immune system is a significant risk factor that increases the likelihood of infection in patients. Individuals with weakened immune responses, due to conditions such as HIV/AIDS, cancer treatments, organ transplants, or autoimmune diseases, are less able to fend off pathogens. This vulnerability means that even common bacteria or viruses can lead to serious infections.

In contrast, proper sterilization, good hand hygiene, and the use of disposable equipment are all practices aimed at reducing the risk of infection. These measures are fundamental to infection control and help protect both patients and healthcare workers by limiting exposure to infectious agents. Thus, while these practices are essential in preventing infections, a compromised immune system heightens the need for robust infection control measures, as these patients are more susceptible to infections that might otherwise be easily handled by individuals with healthy immune systems.
