Summary

Based on recent evidence and in line with global guidelines, WHO recommends droplet and contact precautions for COVID-19 patient care and airborne precautions during aerosol-generating procedures. This aligns with guidelines from various international bodies. However, disparities exist, with some, like the US CDC and European Centre for Disease Prevention and Control, advocating for airborne precautions in all COVID-19 care situations, allowing medical masks in respirator shortages. WHO stresses the rational use of Personal Protective Equipment (PPE), encompassing masks, with a focus on proper healthcare worker behavior, training, and the availability of necessary supplies. Emphasis is placed on frequent hand hygiene, respiratory etiquette, environmental cleaning, and maintaining physical distance from individuals with symptoms.
