Abstract—The world has been exposed to the Coronavirus
Disease 2019 (COVID-19) since late 2019. A global pandemic
has shifted health concerns from air pollution effects to novel
coronavirus disease, similarly to those in Bangkok. Although
Bangkokians have experienced severe PM2.5 conditions since
the last quarter of 2017, the related agencies have failed to
elucidate the crisis. This has been because the fundamental air
quality management is focused on controlling emissions. The
Thai government has sluggishly determined the situations that
lead to the inability to clean up its air. How are air pollution
and disease linked? This article points to the importance of
source management. The lockdown measures revealed reduced
traffic rate and PM2.5 concentrations. Such a close relationship
has shed insights of the consequences of working from home
(WFH). The link between disease and air pollution includes (i)
WFH regulation is one specific way to prevent the transmission
of disease, (ii) this guideline decreases traffic congestion in an
urban city which is one path of diminished pollution discharge
and (iii) then noticeably followed by PM2.5 reductions. Again,
the magnitude of source control is crucial. Reducing pollutions
from traffic by means of WFH has illustrated this
accomplishment. In the midst of this crisis, moving to a new
normal role supports remaining protected from both air
pollution and the pandemic. Nevertheless, the sustainability of
transportation control in an overcrowded city like Bangkok
should be considered as a vital pathway to tackle air pollution.
