👉 Matching infection refers to the process by which a pathogen, such as a virus or bacterium, enters and begins to replicate within a host's body, leading to an infection. This occurs when the pathogen breaches the body's defenses, often through openings like the respiratory tract, skin, or digestive system. Once inside, the pathogen can multiply rapidly, causing damage to host cells and tissues. The immune system then responds by recognizing the invader and mounting an attack, but if the infection is severe or the pathogen is particularly virulent, it can overwhelm these defenses, leading to symptoms and potential complications. This dynamic interaction between the pathogen and the host's immune system is central to understanding how infections develop and progress.
