Airborne
A transmission route in which infectious droplet nuclei ≤5 μm travel through the air and remain suspended, capable of spreading across distances.
Airborne pathogens remain viable in the air for extended periods and distances. N95 respirators filter ≥95% of airborne particles. PAPRs are used when N95 is insufficient or ill-fitting.
