Infection refers to the invasion and multiplication of microorganisms like bacteria, viruses, or fungi within the body. It's like a hostile takeover inside you, where these invaders disrupt normal functions. Think of it as a computer virus that corrupts your system's files. Infections can range from minor annoyances like a cold to serious, life-threatening conditions. The body fights back with its immune system, but sometimes medical intervention is needed. 🦠
