The COVID‐19 pandemic has caused an unprecedented health crisis and economic burden
worldwide. Its etiological agent SARS‐CoV‐2, a new virus in the coronavirus family, has …

The mechanistic factors hypothesized to be key drivers for the loss of infectivity of viruses in
the aerosol phase often remain speculative. Using a next-generation bioaerosol technology …

Background Growing evidence suggests an important contribution of airborne transmission
to the overall spread of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) …

Ventilation is an important engineering measure to control the airborne infection risk of acute
respiratory diseases, eg, Corona Virus Disease 2019 (COVID-19). Occupancy-aided …

Recent epidemiological and experimental findings reconfirm that low indoor air humidity (dry
air) increases the prevalence of acute eye and airway symptoms in offices, result in lower …

The airborne microorganisms in the aerosols are one main transmission way of pathogenic
microorganisms and therefore inactivation of microorganisms in aerosols could effectively …

In response to the COrona VIrus Disease 2019 (COVID-19) pandemic, extensive research
has been conducted to explore, understand, and model the dynamics of expelled respiratory …

The airborne transmission of COVID-19 has drawn immense attention to bioaerosols. The
topic is highly relevant in the indoor hospital environment where vulnerable patients are …

Background Longitudinal studies are critical to informing evolving responses to COVID-19
but can be hampered by attrition bias, which undermines their reliability for guiding policy …

Indoor airflow patterns and the spreading of respiratory air were studied using the large-
eddy simulation (LES) computational fluid dynamics (CFD) approach. A large model room …
