Infections in patients are typically characterized by a range of physical signs and symptoms that reflect the body's immune response to pathogens. Indicators such as fever, redness, and swelling are well-documented manifestations of infection.

Fever is a common response to infection as the body raises its temperature to create an environment less hospitable to harmful microorganisms. Redness, or erythema, often occurs at the site of infection due to increased blood flow as the immune system mobilizes to fight off invaders. Swelling, or edema, can also be observed as fluid accumulates in tissues due to inflammatory responses triggered by infection.

In contrast, increased energy is not an indicator of infection; rather, it is generally the opposite. When a body is fighting an infection, individuals often feel fatigued or weak due to the energy being diverted to support the immune system in combating the infection. Therefore, increased energy does not align with the physiological responses typically associated with infection.
