Which of the following is a common sign of infection?

A common sign of infection is fever. This response occurs because the body's immune system raises its temperature to help fight off pathogens such as bacteria or viruses. Fever is a defense mechanism that can enhance the activity of immune cells and create an environment less favorable for the growth of pathogens. It is typically accompanied by other signs of infection, such as chills, sweating, and malaise. While increased appetite, anxiety, and drowsiness can occur in various situations, they are not specifically indicative of infection. Increased appetite is often seen in healthy individuals or those recovering from illness, while anxiety can arise from stress or other psychological conditions. Drowsiness might suggest fatigue or other health issues but does not directly signal an infection. Thus, the presence of fever stands out as a clear and significant indicator of infection.
