What is the difference between standard precautions and transmission-based precautions?

Standard precautions are the baseline infection-prevention practices used with every patient to prevent exposure to blood, body fluids, and other potentially infectious materials. They form the default level of protection in all patient care, including hand hygiene, appropriate use of gloves, gowns, masks, or eye protection based on the anticipated exposure, safe handling and disposal of sharps, proper cleaning and disinfection of equipment, and respiratory hygiene. Transmission-based precautions are additional measures layered on when a patient has, or is suspected to have, an infection that requires extra protection due to how that pathogen spreads. These precautions supplement standard precautions rather than replace them. They are categorized by the route of transmission: contact precautions add gloves and gown when there's risk of touching contaminated surfaces or the patient’s skin or wound secretions; droplet precautions involve a mask (and sometimes eye protection) when pathogens spread through close respiratory contact; and airborne precautions require specialized settings and respirators (like an N95) for diseases that can be inhaled and travel through the air. So, the difference is that standard precautions are applied to all patients as the default, while transmission-based precautions are added on top for specific infections to address additional routes of spread.
