Abstract

PM2.5, a fine solid aerosols with diameter of 2.5 µm or less is ambient air [1]. There have reports of association between respiratory viruses and PM2.5 [2], but no correlation was found between PM’s diameter and the virus concentration [1]. PM2.5 in indoor environments is derived mainly from common outdoor sources [3-5]. PM2.5 with longer lifetime of the particles can be deposited in hospitals’ flooring [6,7] and any other surface materials [8,9]. A recent study at a teaching hospital, in Kuala Lumpur, Malaysia revealed that there was highest SARS-CoV-2 (COVID-19) RNA on PM2.5 in the number-of-occupant wards [1]. They demonstrated the association between the ward’s design and the SARS-CoV-2 (COVID-19)-laden PM2.5 (Figure 1 and Figure 2) [1].
