What is a common sign of infection?

• A. Swelling
• B. Fever
• C. Pain
• D. Redness

Answer: (B)

A common sign of infection is fever. Fever occurs as a physiological response to infection, where the body raises its temperature to create an environment that is less favorable for pathogens. This response is part of the immune system's effort to fight off the infection and is usually accompanied by other symptoms such as chills, sweating, and general malaise. Fever is often one of the first indicators healthcare professionals look for when assessing a patient for potential infections, because it reflects the body's systemic response to invading pathogens. While other signs such as swelling, pain, and redness can also indicate infection, they can be associated with various conditions, making fever a more universal and recognized sign of infection across different types of illnesses.
