During an infection, what does the immune system typically try to induce to help fight the pathogens?

The immune system often induces fever as a response to infection because elevated body temperature can enhance the body's ability to fight off pathogens. Fever is typically triggered by the release of pyrogens, which are substances that induce fever and are produced as a result of an immune response to infections.

A higher body temperature can impede the growth of certain bacteria and viruses, making it more difficult for them to replicate. Additionally, fever can enhance the activity of immune cells, such as T cells and phagocytes, which are vital in recognizing and destroying invaders. The increased metabolic rate associated with fever also accelerates the immune response, allowing for a quicker reaction to pathogens.

While sweat is a mechanism for cooling down and shivering is a response to cold, they do not play direct roles in fighting infections. Inflammation is indeed another critical response of the immune system that helps fight infections, involving increased blood flow and the recruitment of immune cells to the affected area. However, fever serves a more systemic role by raising the overall body temperature to create an environment that is less conducive for pathogens and more supportive for immune function.
