Aerosolisation and airborne are two different things, says minister

Multiple research papers have been published regarding the use of aerosolisation to test how far and how long a virus can remain in the air.

This was brought up by Minister of Health Dato Seri Setia Dr Haji Mohd Isham bin Haji Jaafar during a press conference recently.

He also made a distinction between aerosolisation, which is a process of converting a material into the form of particles that are small and light enough to be carried on the air, and an airborne disease, which is any disease caused by pathogens that can be transmitted through the air by small particles.

Aerosolisation, he said, is carried out for medical research purposes, most notably among ear, nose and throat (ENT) anaesthetists. It is, thus, vital that a surgical mask is used during these studies.
