The practice of social distancing and wearing masks has been popular worldwide in
combating the contraction of COVID-19. Undeniably, although such practices help control …

In the past few years, significant efforts have been made to investigate the transmission of
COVID-19. This paper provides a review of the COVID-19 airborne transmission modeling …

Although the relative importance of airborne transmission of the SARS-CoV-2 virus is
controversial, increasing evidence suggests that understanding airflows is important for …

In this study, the motion and distribution of droplets containing coronaviruses emitted by
coughing of an infected person in front of a classroom (eg, a teacher) were investigated …

Ambient temperature and humidity strongly affect inactivation rates of enveloped viruses, but
a mechanistic, quantitative theory of these effects has been elusive. We measure the stability …

The novel coronavirus disease (COVID-19) spread pattern continues to show that
geographical barriers alone cannot contain a virus. Asymptomatic carriers play a critical role …

The ongoing Covid-19 pandemic has focused our attention on airborne droplet
transmission. In this study, we simulate the dispersion of cough droplets in a tropical outdoor …

People in cities use elevators daily. With the COVID-19 pandemic, there are more worries
about elevator safety, since elevators are often small and crowded. This study used a proven …

Coronavirus disease 2019 (COVID-19), due to infection by the severe acute respiratory
syndrome coronavirus 2 (SARS-CoV-2), is now causing a global pandemic. Aerosol …

Coughing has been confirmed as a significant vector for transmitting respiratory diseases. It
can be modelled physically as a turbulent jet to study the dispersion of expiratory droplets …
