Which isolation precaution applies to measles in pediatrics?
Correct Answer:
Airborne precautions.
Explanation:
Measles spreads through airborne particles that can linger in the air and travel beyond close contact. Because of this, the appropriate isolation approach is airborne precautions. In a hospital setting, this means placing the child in a negative-pressure room and ensuring staff wear respirators (such as an N95) or higher-level protection when entering the room. Standard precautions are used for all patients, but airborne precautions specifically address the airborne transmission risk of measles. Droplet or contact precautions alone wouldn’t fully prevent spread since measles can be transmitted through the air over longer distances.
