ACIPC Position Statement Release: Terminology for Pathogens that Transmit through the Air

Megan Reilly

The Australasian College for Infection Prevention and Control (ACIPC) has released a new position statement titled “Terminology for pathogens that transmit through the air”.

ACIPC’s position statement recommends terminology for pathogens that transmit through the air to be standardised as follows:

✅ Introduction of the term “infectious respiratory particles” (IRPs) to describe respiratory particles containing pathogens that travel through the air.

✅ Recognition of the spectrum of IRP particle sizes and moving away from using aerosols and droplets to define IRP size.

✅ The use of “transmission through the air” as the overarching term to describe the movement of IRPs, with subcategories of “airborne/inhalation” and “direct deposition”.

✅ The term “particulate filter respirators” (PFR) is used to replace P2/N95 respirators to provide consistency.
