What are the 4 common symptoms associated with infection?

1. Fever: An elevated body temperature is a common sign of infection, as the body's immune system responds to the presence of pathogens by raising its temperature in an attempt to kill or slow down the growth of the invading microorganisms.

2. Inflammation: Infection often leads to inflammation, which is characterized by redness, swelling, heat, and pain. These symptoms occur as the body sends immune cells and fluids to the site of infection to fight off the pathogens and repair damaged tissues.

3. Pus formation: In some cases of infection, pus may form. Pus is a thick, yellowish-white fluid that consists of dead white blood cells, bacteria, and cellular debris. It is a sign of the body's attempt to localize and contain the infection.

4. General malaise: Infection can also cause general symptoms such as fatigue, weakness, and loss of appetite. These symptoms occur as the body diverts energy towards fighting off the infection, leading to a decrease in overall function and well-being.
