With infectious diseases transmitted through aerosols, HVAC systems can have a major effect on the transmission from the primary host to secondary hosts. Decreasing exposure of secondary hosts is an important step in curtailing the spread of infectious diseases. Designers of mechanical systems should be aware that ventilation is not capable of addressing all aspects […]

Since first being reported in December 2019, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has rapidly spread worldwide. The resulting coronavirus disease of 2019 (COVID-19) was declared a pandemic by the World Health Organization (WHO) in March 2020. SARS-CoV-2 is considered to primarily be spread by droplet transmission and direct contact. Given the behaviour
Coronavirus disease 2019 (COVID-19) was first identified in China in late 2019 and is caused by newly identified severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Previous studies had reported the stability of SARS-CoV-2 in cell culture media and deposited onto surfaces under a limited set of environmental conditions. Here, we broadly investigated the effects of
The transmission modes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) remain controversial. At the emerging stage of the pandemic, many countries implemented high-level precautions, including airborne and contact precautions, to prevent the spread from patients to health care professionals (HCPs). An emerging understanding of SARS-CoV-2 epidemiology, which is primarily transmitted from person to person
