Which of the following is NOT a sign of an infection?

Loss of sensation is not typically considered a sign of infection. Signs of infection generally include the presence of pus, red streaks radiating from a wound, and swelling, all of which indicate that the body is responding to an inciting event, such as bacteria entering a wound. Pus is a byproduct of the immune response to pathogens, red streaks can indicate lymphangitis (the spread of infection through the lymphatic system), and swelling often occurs due to inflammation associated with infection. In contrast, loss of sensation can be an indication of nerve damage or compromise, which is not directly related to the symptoms of infection and can suggest different underlying issues. Understanding these distinctions helps in assessing wounds and identifying possible complications.
