Which symptom might indicate an increasing infection?

Pus buildup is a significant indicator of infection. When the body responds to an infection, white blood cells rush to the site to combat the invading pathogens. This immune response can lead to the formation of pus, which is composed of dead white blood cells, bacteria, and tissue debris. The presence of pus typically indicates that the body is actively fighting an infection, and its accumulation suggests that the infection may be worsening or not adequately responding to treatment. Recognizing pus as a symptom is crucial in assessing the severity of an infection and determining the appropriate medical interventions needed.

In contrast, dry skin, cold sweat, and symptom-free states do not typically signify an active or worsening infection, making them less relevant when monitoring for signs of increasing infection severity.
