Editorial
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’ flooring6,7 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

(Note: The beds in the figure does not represent the actual number of beds in the wards, at a teaching hospital in Kuala Lumpur, Malaysia).1

.Conclusion
In conclusion, in an enclosed environment, PM2.5 with number of airborne-SARS-CoV-2 (COVID-19) can influence patients’ clinical manifestations.
