Which of the following is also listed as a bed bug medical impact?

• A. Pain, welt, and itchiness
• B. Loss of sleep
• C. Allergic reactions
• D. Anxiety

Answer: (C)

Bed bug bites can trigger physiological responses in the body, and allergic reactions are a recognized medical impact because they involve the immune system reacting to bites. This can lead to more pronounced skin reactions and, in some cases, may require medical care. While bite sites commonly cause pain, welts, and itching, those are local symptoms of the bite itself rather than broader medical effects. Loss of sleep and anxiety are important concerns related to infestation, but they are behavioral or psychological impacts rather than direct medical reactions. So, allergic reactions best fit the category of a bed bug medical impact.
