Why do people get fevers?
A
It is a sign pathogens are taking over
B
pathogens cannot grow at high temperatures
C
because your body cannot fight the infection
D
None of the above
Explanation: 

Detailed explanation-1: -Some pyrogens are produced by body tissue; many pathogens also produce pyrogens. When the hypothalamus detects them, it tells the body to generate and retain more heat, thus producing a fever. Children typically get higher and quicker fevers, reflecting the effects of the pyrogens upon an inexperienced immune system.

Detailed explanation-2: -Pathophysiology of Fever Fever results when something raises the hypothalamic set point, triggering vasoconstriction and shunting of blood from the periphery to decrease heat loss; sometimes shivering, which increases heat production, is induced.

Detailed explanation-3: -Once the higher temperature is set, your body begins working to increase its temperature. You will feel cold because you are now at a lower temperature than your brain thinks you should be so your body will begin to shiver to generate heat and raise your temperature. This is the chills.
