Hand hygiene is the most crucial means to prevent disease transmission in healthcare settings. It directly interrupts the primary pathway through which pathogens spread to healthcare workers, patients, and visitors. Regular hand hygiene practice is fundamental to all infection control efforts and remains the single most effective measure for reducing healthcare-associated infections across all patient populations.

Healthcare employers must provide workers with personal protective equipment including gowns, masks, face shields, eye protection, gloves, and shoe covers. The specific PPE used depends on risk assessment and the extent of exposure anticipated. For example, surgical gloves are worn during high-risk procedures like lumbar punctures. PPE selection varies based on the work area and patient contact level.

Respiratory hygiene requires covering the nose and mouth with a tissue during sneezing or coughing, followed by hand hygiene. This practice prevents respiratory droplets from contaminating the environment and spreading pathogens to others. Proper cough etiquette is a routine standard precaution observed in all healthcare settings to minimize disease transmission among patients, staff, and visitors.

Sharps must be discarded immediately in puncture-resistant containers, and recapping needles using the two-hand method is prohibited to prevent needlestick injuries. Parenteral medications must be administered using aseptic techniques to prevent contamination and infection. These practices are essential standard precautions that protect healthcare workers and patients from bloodborne pathogen exposure and medication-related infections.

Universal precautions apply when handling sputum, feces, sweat, vomit, tears, urine, or nasal secretions only if blood is visible. Body fluids without visible blood are not considered contaminated because transmission of Hepatitis B or HIV through these fluids is extremely low or non-existent. However, standard precautions for environmental cleaning and general hygiene remain important for all patient care activities.

Standard precautions vary depending on the work area and job responsibilities. Employees with sitting non-patient-oriented jobs require different precautions than nurses and laboratory technicians working directly with patients. However, everyone should observe basic safety precautions to protect themselves and colleagues. Risk assessment determines the specific measures needed for each role and healthcare setting.

Routine cleaning and disinfection of environmental surfaces and repeatedly touched areas is essential. Patient care equipment and devices must be appropriately handled, cleaned, and disinfected between uses. Used linens must be handled to prevent exposure and contamination of clothing during transport and processing. These practices reduce environmental contamination and prevent pathogen transmission in healthcare settings.
