The static air pressure in the surrounding adjacent areas is used to prevent the air containing pathogenic microorganisms from spreading outwards. Note. The area consisting of multiple negative pressure isolation wards and patient passages, medical staff passages and related buffer rooms is called a negative pressure isolation ward. 3.2 airborne transmission The virus is transmitted by droplet nuclei (≤5 μm) suspended in the air, which can be transmitted over long distances ( >1 m) and remain infectious for a long time. Caused by the spread. [Source. WS/T 311-2023, 3.5] 3.3 Isolation Measures that use various methods and technologies to prevent the spread of pathogens from patients, carriers and places to others.
