👉 An infection, particularly when it involves a pathogen like bacteria or a virus, can be likened to peeling an onion. Just as the outer layers of an onion are removed to reveal the softer, more vulnerable inner parts, an infection begins with an initial breach in the body's defenses, often at a site of entry such as a cut or mucous membrane. Once inside, the pathogen multiplies and spreads, but the body's immune system responds by sending white blood cells to attack and neutralize the threat. This process involves a series of interactions where the pathogen is eventually overwhelmed or eliminated, much like how the layers of the onion are stripped away until only the core remains. However, if the infection persists or the immune response is weak, it can lead to more severe complications, akin to the tough outer layers of the onion remaining intact and causing ongoing issues.
