Active infection or febrile illness is an absolute contraindication to exercise because of cardiovascular strain risk. Which scenario fits this rule?

• A. Mild dehydration.
• B. Allergic rhinitis.
• C. Active infection or febrile illness.
• D. Chronic bronchitis.

Answer: (C)

Active infection or fever places the body under systemic stress and raises cardiovascular workload. When you have a fever, heart rate and metabolic demand are already higher as the body fights the illness. Adding exercise increases cardiac strain further, which can heighten the risk of complications such as dehydration, overheating, arrhythmias, or even myocarditis in some cases. Because of these risks, exercise is avoided until the fever resolves and the infection subsides. Among the scenarios, the one that describes an active infection or febrile illness clearly fits this rule. The others—mild dehydration, allergic rhinitis, or chronic bronchitis without an acute flare—do not represent this same immediate cardiovascular risk level and are not absolute contraindications to exercise.
