👉 Pre-infection refers to the period immediately preceding an individual's exposure to a pathogen, during which their immune system is actively preparing to combat potential threats. This phase involves the recognition of pathogens by immune cells and the initiation of various immune responses, such as the production of antibodies and the activation of immune cells like T-cells and macrophages. Pre-infection is crucial for mounting an effective defense against infections; it allows the body to generate memory cells that can provide faster and more robust protection upon subsequent exposures to the same pathogen. However, if the immune system is compromised or fails to respond adequately during this period, the risk of infection increases significantly.
