Looking beyond COVID-19 vaccine phase 3 trials

Jerome H. Kim et al.

Summary: Following the announcement of COVID-19 vaccine efficacy in clinical trials, a comprehensive strategy is needed for global vaccination, including manufacturing, support, supply coordination, equitable distribution, and logistics. Additionally, addressing scientific questions to improve vaccine efficacy is crucial for ending the pandemic effectively and efficiently.

On airborne virus transmission in elevators and confined spaces

Talib Dbouk et al.

Summary: This study investigates the impact of air ventilation systems on airborne virus transmission in confined spaces using an elevator as a prototype. It shows that the position of inlets and outlets significantly influences flow circulation and droplet dispersion, and that air purifiers alone cannot eliminate airborne transmission. The practical conclusion is that the design and placement of air purifiers and ventilation systems play a crucial role in reducing droplet dispersion and airborne virus transmission within confined spaces.

Numerical study of virus transmission through droplets from sneezing in a cafeteria

Liangyu Wu et al.

Summary: The numerical simulation shows that dining face to face in a cafeteria is highly susceptible to direct infection by others' respiratory droplets, with sneezing from a standing person resulting in longer survival time of droplets in the air. Closing off the horizontal supplying air conditioner does not prevent droplet spread. It is recommended that cafeterias only accept take-away orders and sanitize all surfaces.

Airborne transmission of virus-laden aerosols inside a music classroom: Effects of portable purifiers and aerosol injection rates

Sai Ranjeet Narayanan et al.

Summary: This study investigated the effects of placing portable air purifiers in a classroom and different aerosol injection rates on aerosol concentrations. The results showed that proper placement of purifiers significantly reduced airborne aerosol numbers, while the injection rate had a linear correlation with aerosol suspension and deposition rates.

Simulation-based study of COVID-19 outbreak associated with air-conditioning in a restaurant

Han Liu et al.

Summary: The study utilized advanced numerical methods to investigate indoor airflow and aerosol transport in a restaurant setting, revealing a direct link between regions of high aerosol exposure index and infection patterns. It further pinpointed the influence of environmental parameters on infection risks, highlighting the need for more effective preventive measures.

Effect of individually controlled personalized ventilation on cross-contamination due to respiratory activities

Elvire Katramiz et al.

Summary: The study found that infected individuals using lower PV flow rates in tandem seating and higher flow rates in face-to-face seating can achieve minimal exposure levels in an office setting. Additionally, the average inhaled intake fraction was 31% lower for face-to-face seating during coughing and 86% lower during breathing compared to tandem seating.

Computer simulation of the SARS-CoV-2 contamination risk in a large dental clinic

Jonathan Komperda et al.

Summary: This study conducted a large-scale numerical simulation of a real-world dentistry clinic with aerosol-generating procedures, analyzing the dispersion of evaporating droplets emitted during ultrasonic dental scaling. Results indicated concerns about aerosols' long residence times and travel distances exceeding social distancing guidelines, expanding contamination beyond the immediate patient treatment areas.

Simulation of aerosol transmission on a Boeing 737 airplane with intervention measures for COVID-19 mitigation

Khaled Talaat et al.

Summary: Identifying economically viable intervention measures to reduce COVID-19 transmission on aircraft is crucial, especially with the emergence of new SARS-CoV2 variants. Using computational simulations, it was found that employing sneeze shields on full capacity flights can significantly reduce aerosol transmission compared to reduced capacity flights without shields.

Breathing, virus transmission, and social distancing-An experimental visualization study

Venugopal Arumuru et al.

Summary: With the outbreak of COVID-19, public awareness has increased about the droplet mode of virus transmission, leading to preventive measures such as wearing masks and social distancing. Recent reports suggest the virus may also transmit through aerosolized particles, with breathing being a potential source of transmission. Experimental visualization of droplet transport through breathing has been conducted to evaluate the efficacy of various protective measures, with commercial five-layered masks found to be the most effective.
