What are the signs of an infection?

The signs of an infection often include redness, warmth, swelling, pain, and sometimes fever. Each of these indicators plays a role in the body's response to infection.

Redness and warmth are typically caused by increased blood flow to the affected area as the immune system responds to pathogens. Swelling occurs due to the accumulation of fluid and immune cells at the site of infection, which helps to isolate and combat the invading microbes. Pain is commonly experienced due to inflammation and irritation of tissues. Fever is a systemic response that can help to inhibit the growth of pathogens and enhance the immune response.

Together, these signs provide a comprehensive indication of an infection, making this choice accurate and significant for identifying and assessing the presence of infections in clinical practice.
