Modeling of dispersion of aerosolized airborne pathogens exhaled in indoor spaces

By / / Leave a Comment

Since the beginning of the COVID-19 pandemic, there has been a lack of data to quantify the role played by breathing-out of pathogens in the spread of SARS-Cov-2 despite sufficient indication of its culpability. This work aims to establish the role of aerosol dispersion of SARS- Cov-2 virus and similar airborne pathogens on the spread […]

COVID-19 Exposure Assessment Tool (CEAT): Exposure quantification based on ventilation, infection prevalence, group characteristics, and behavior

By / / Leave a Comment

The coronavirus disease 2019 (COVID-19) Exposure Assessment Tool (CEAT) allows users to compare respiratory relative risk to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) for various scenarios, providing understanding of how combinations of protective measures affect risk. CEAT incorporates mechanistic, stochastic, and epidemiological factors including the (i) emission rate of virus, (ii) viral aerosol degradation

Behavioral impacts on residential food provisioning, use, and waste during the COVID-19 pandemic

By / / Leave a Comment

The COVID-19 pandemic caused unprecedented disruptions to food systems, leading to both food shortages and food waste across the supply chain. These disruptions have, in turn, altered how people consume and then ultimately discard food. To better understand these impacts, their underlying drivers, and their sustainability implications, this study surveyed U.S. consumers about food purchasing,

Consumer emotions and collaborative consumption: The effect of COVID-19 on the adoption of use-oriented product-service systems

By / / Leave a Comment

The COVID-19 pandemic is expected to widely change how consumers evaluate market offerings. In this research, we identified consumers’ emotions on the adoption of use-oriented Product-Service-Systems (PSS) and the effect of COVID-19 on such emotions using pre- and amid-COVID-19 samples. The results indicate that positive emotions are generally more associated with the process of adopting

Social distancing remains key during vaccinations

By / / Leave a Comment

A global effort to develop vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) began early in 2020. In mid-December, the U.S. Food and Drug Administration approved emergency use authorization for two vaccines that successfully concluded their phase 3 trials, and vaccine distribution in the United States began shortly afterwards. As vaccinations progress, the public

UV-C irradiation is highly effective in inactivating and inhibiting SARS-CoV-2 replication

By / / Leave a Comment

The COVID-19 pandemic caused by SARS-CoV-2 virus has had an enormous, as yet barely understood, impact on health and economic outlook at the global level. The identification of effective microbicide approaches is of paramount importance in order to limit further viral spread, as the virus can be transmitted via aerosol and can survive for hours

Viable SARS-CoV-2 in the air of a hospital room with COVID-19 patients

By / / Leave a Comment

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), genus Betacoronavirus, subgenus Sarbecovirus, family Coronaviridae, is a positive-polarity single-stranded RNA virus that probably originated in bats and is the causative agent of coronavirus disease of 2019 (COVID-19). The dynamics of the COVID-19 pandemic have proven to be complex. Many challenges remain pertaining to a better understanding of

Indoor Air Changes and Potential Implications for SARS-CoV-2 Transmission

By / / Leave a Comment

Buildings have been associated with spread of infectious diseases, such as outbreaks of measles, influenza, and Legionella. With SARS-CoV-2, the majority of outbreaks involving 3 or more people have been linked with time spent indoors, and evidence confirms that far-field airborne transmission (defined as within-room but beyond 6 feet) of SARS-CoV-2 is occurring. Controlling concentrations

Aerosol-generating procedures and infective risk to healthcare workers from SARS-CoV-2: the limits of the evidence

By / / Leave a Comment

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
