Extended short-range airborne transmission of respiratory infections

Wenzhao Chen et al.

Summary: The debate and scientific inquiries about airborne transmission of respiratory infections continue. This study considers long-range airborne transmission as an extended short-range airborne route and proposes the concept of effective short-range distance. The data show that factors like ventilation rate, room volume per person, and the ratio of infected to susceptible individuals impact the effective short-range distance.

Aerosol transmission of SARS-CoV-2 due to the chimney effect in two high-rise housing drainage stacks

Qun Wang et al.

Summary: Studies have shown that stack aerosols generated within vertical drainage stacks in high-rise buildings may lead to outbreaks of COVID-19 and the spread of SARS-CoV-2, mainly through the chimney effect of drainage pipes. By injecting tracer gas into the drainage stacks and monitoring its distribution in different areas, researchers were able to confirm that the spread of the virus was in line with the distribution of infected cases, providing direct evidence for long-range aerosol transmission through drainage pipes.

Predominant airborne transmission and insignificant fomite transmission of SARS-CoV-2 in a two-bus COVID-19 outbreak originating from the same pre-symptomatic index case

Pan Cheng et al.

Summary: This study in Hunan province, China, revealed the leading role of airborne SARS-CoV-2 transmission in a poorly ventilated indoor environment, emphasizing the need for more targeted interventions in such settings. The research also showed that the quanta generation rate of the index case differed between the two buses and transmission occurred on the same day in the afternoon.

How human thermal plume influences near-human transport of respiratory droplets and airborne particles: a review

Shiyi Sun et al.

Summary: The human thermal plume plays a crucial role in facilitating the airborne transmission of COVID-19 in enclosed spaces by elevating small droplets and airborne particles into the breathing zone. Analyzing key variables in the formation of the thermal plume can help to better understand the transmission dynamics in public spaces.

COVID-19 spread in a classroom equipped with partition-A CFD approach

Mahshid Mirzaie et al.

Summary: This study investigated the motion and distribution of droplets containing coronaviruses emitted by coughing of an infected person in front of a classroom using CFD. Results showed that seat partitions can prevent infection to a certain extent. Increasing ventilation airflow speeds can accelerate droplets in the airflow direction, reducing trapping time by solid barriers.

Dilution-based evaluation of airborne infection risk-Thorough expansion of Wells-Riley model

Sheng Zhang et al.

Summary: The study introduces a dilution-based evaluation method for airborne infection risk, which is proven to be a comprehensive extension of the Wells-Riley model for evaluating airborne infection risk with spatial and temporal resolutions, compared to the well-recognized models. Experiments in a mock hospital ward demonstrate the effectiveness of the proposed method in assessing airborne infection risk both spatially and temporally.

Revisiting physical distancing threshold in indoor environment using infection-risk-based modeling

Fan Liu et al.

Summary: The study found that the universal 2-meter physical distancing rule based on droplet physics is not always applicable in realistic indoor settings and could potentially increase disease transmission risks. In thermally stratified environments, the infection risk may exhibit multiple peaks beyond 2 meters. Therefore, it is suggested to combine various strategies such as wearing masks, reducing exposure time, and controlling indoor thermal stratification in disease prevention.

Y Evidence for lack of transmission by close contact and surface touch in a restaurant outbreak of COVID-19

Nan Zhang et al.

Summary: The study examined a COVID-19 outbreak in a restaurant in Guangzhou and found that the main transmission route was through long-range airborne transmission. There was no significant correlation between infection risk via fomite and close contact routes among non-family members, ruling out fomite and close contact transmission in the outbreak.

CFD Simulation of the Airborne Transmission of COVID-19 Vectors Emitted during Respiratory Mechanisms: Revisiting the Concept of Safe Distance

Mariam et al.

Summary: The study investigated the airborne transmission of COVID-19 virus in an indoor office setting using computational fluid dynamics simulations. It found that respiratory events such as coughing and sneezing, as well as normal and loud talking, can spread particles to receptors in the room. The research highlights the limitations of the safe distance approach and suggests the use of air curtains for better particle removal in indoor spaces.

Summary: This research used discrete phase modeling to simulate the diffusion characteristics of droplets at different temperatures and exhalation positions, identifying low-risk and high-risk areas in buses. The study found that sitting in the last row away from the door is the safest option, while seats near the door and in the middle are higher risk areas.
