SARS-CoV-2 Infection Among Health Care Workers Despite the Use of Surgical Masks and Physical Distancing—the Role of Airborne Transmission

This report reports for the first time SARS-CoV-2 nosocomial infections despite using surgical masks and physical distancing, and may provide possible evidence for airborne transmission of Sars-Cov-2.

Brought to Light: How Ultraviolet Disinfection Can Prevent the Nosocomial Transmission of COVID-19 and Other Infectious Diseases

This review considers how pathogens are transmitted in healthcare facilities, the mechanism of UV microbial inactivation and the documented activity of UV against clinical pathogens, including severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) as well as multidrug resistant organisms (MDROs) that are commonly transmitted in Healthcare facilities.

Short-range exposure to airborne virus transmission and current guidelines

Detailed experiments and accurate computationally-intensive numerical simulations of droplet-laden turbulent puffs emitted during sneezes are used to produce original virus exposure maps, which can be a useful instrument for health scientists and practitioners to calibrate new guidelines to prevent short-range airborne disease transmission.

What’s in the Pipeline? Evidence on the Transmission of SARS-CoV-2 via Building Wastewater Plumbing Systems

An examination of the processes which underlie this mode of transmission, and the existing epidemiological evidence, as well as existing mitigation strategies are presented; significant gaps in the state of the knowledge are also identified.

A Predictive Modelling Framework for COVID-19 Transmission to Inform the Management of Mass Events

The approach ties together three main components: reliable modelling of the number of infectious cases at the time of the event, evaluation of the efficiency of pre-event screening and risk mitigation protocols, and modelling the transmission dynamics during the event.

Epidemic disease and the state: Is there a tradeoff between public health and liberty?

Evidence is presented that the existence of a tradeoff between public health and freedom can obtain in the short run but that, in the long run, the negative relationship is reversed and the trade-off disappears.



Transmission of SARS-CoV-2: implications for infection prevention precautions

M Modes of transmission of virus causing COVID-19: implications for IPC precaution recommendations and how to proceed with precautionary measures are investigated.

Aerosol Generating Procedures and Risk of Transmission of Acute Respiratory Infections to Healthcare Workers: A Systematic Review

It is suggested that some procedures potentially capable of generating aerosols have been associated with increased risk of SARS transmission to HCWs or were a risk factor for transmission, with the most consistent association across multiple studies identified with tracheal intubation.

High SARS-CoV-2 Attack Rate Following Exposure at a Choir Practice - Skagit County, Washington, March 2020.

Data demonstrate the high transmissibility of SARS-CoV-2 and the possibility of superemitters contributing to broad transmission in certain unique activities and circumstances and recommend that persons avoid face-to-face contact with others, not gather in groups, avoid crowded places, maintain physical distancing of at least 6 feet to reduce transmission, and wear cloth face coverings in public settings where other social distancing measures are difficult to maintain.

Influenza Aerosols in UK Hospitals during the H1N1 (2009) Pandemic – The Risk of Aerosol Generation during Medical Procedures

Although the probability of detecting positive H1N1 (2009) positive aerosols when performing various AGPs on intensive care patients above the baseline rate did not reach significance, there was a trend towards hierarchy of AGPs, placing bronchoscopy and respiratory and airway suctioning above baseline (background) values.

Coronavirus Disease 2019 (COVID-2019) Infection Among Health Care Workers and Implications for Prevention Measures in a Tertiary Hospital in Wuhan, China

In this study, most infections among health care workers occurred during the early stage of the COVID-19 outbreak and in low-contagion areas; routine screening may be helpful in identifying asymptomatic carriers.

Close contact behaviour in indoor environment and transmission of respiratory infection.

This review synthesises the existing understanding of the mechanisms of close contact transmission and proposes the existence of three sub-routes of transmission: short-range airborne, large droplets, and immediate body-surface contact.
