Which precautions prevent spread of harmful germs that travel in the air at a distance, using Standard Precautions plus a respirator?

Airborne transmission involves germs that stay suspended in the air and can travel long distances, so protecting the worker requires Standard Precautions plus Airborne Precautions. This means placing the patient in a private room with negative air pressure and a closed door, limiting patient movement, and ensuring staff wear a respirator (N95 or higher) whenever entering the room or working near the patient. The respirator filters small particles that can be inhaled deep into the lungs, providing essential protection against those easily dispersed germs. Diseases that require this approach include tuberculosis, measles, and varicella. These other options don’t address how tiny particles travel through the air. Contact precautions focus on preventing transmission through direct or indirect contact with the patient or contaminated surfaces and use gloves and gowns. The chain of infection is a framework that describes how infections spread, not a specific protective measure. Body fluids precautions relate to handling potentially infectious bodily fluids and use gloves and other PPE, but they don’t specifically tackle airborne spread.
