Pyrogens are substances that can cause a fever when introduced into the body. They are typically produced by bacteria during their growth and are released into the environment as toxins. Pyrogens can be found in various environments, including soil, water, and even on our own skin. They can enter the body through cuts, abrasions, or even minor exposure to bacteria. Once inside the body, pyrogens stimulate the immune system to release chemicals that cause a fever. This is why we often feel hot and ill after being exposed to someone with a fever or after being around sick people.
