Which action is included in CDC infection control measures?

• A. Quarantine of sick contacts
• B. Infecting others to test
• C. Unscreened exposure
• D. Delayed reporting

Answer: (A)

Controlling infectious spread relies on separating people who might transmit infection from those who are not yet contagious. Quarantine of sick contacts fits this goal by restricting movement of individuals who have been exposed or may be contagious, helping to prevent further transmission until their infectious status is known. This is a standard public-health practice used in clinics, hospitals, and during outbreaks to break the chain of transmission. The other options don’t fit infection-control practice: deliberately infecting others to test is unethical and unlawful; unscreened exposure increases risk rather than reducing it; delaying reporting obstructs timely public-health action that helps contain outbreaks.
