👉 Ready-to-infection, or RTI, refers to a state where a host is susceptible to infection due to compromised defenses or exposure to pathogens. This can occur through various means, such as physical trauma, immunosuppression, or environmental factors that weaken the body's natural barriers. In this vulnerable state, microorganisms like bacteria, viruses, or fungi can easily invade and cause disease. RTI is a critical concept in epidemiology and clinical practice, highlighting the importance of maintaining robust immune function and preventive measures to reduce the risk of infection in at-risk populations.
