Exhaled Breath Aerosol Shedding of Highly Transmissible Versus Prior Severe Acute Respiratory Syndrome Coronavirus 2 Variants

Jianyu Lai et al.

Summary: This study measured the infectivity and rate of SARS-CoV-2 shedding into exhaled breath aerosol (EBA) by individuals infected with Delta and Omicron variants. The results showed that these variants shed more viral RNA copies into EBAs compared to ancestral strains and variants not associated with increased transmissibility. Vaccinated and boosted individuals infected with SARS-CoV-2 can also shed infectious viral aerosols. These findings highlight the dominant role of infectious aerosols in the transmission of SARS-CoV-2.

Unanswered questions on the airborne transmission of COVID-19

Zhaolin Gu et al.

Summary: Policies and measures to control pandemics often fail, as the environmental drivers of transmission and infection are not well understood. This review explores the effects of atmospheric particulate properties, vortex zones, and air pollution on virus survivability and transmission. Factors such as particle size, chemical constituents, electrostatic charges, and moisture content of airborne particles have notable effects on virus transmission. Additionally, vortex zones and human thermal plumes greatly influence the aerodynamics of airborne particles, impacting virus transport. Understanding these factors may explain the positive correlations between COVID-19 infection and mortality with air pollution.

Expiratory Aerosol pH: The Overlooked Driver of Airborne Virus Inactivation

Beiping Luo et al.

Summary: Respiratory viruses, such as influenza virus and SARS-CoV-2, can be transmitted by the airborne route. While air filtration and ventilation can reduce virus concentration, they fail to consider the impact of aerosol acidity on virus persistence. This study finds that exhaled particles in indoor air become mildly acidic, rapidly inactivating influenza virus but requiring days for SARS-CoV-2. Manipulating aerosol pH can significantly affect virus transmission and mitigation strategies.

Exposure to PM has been linked to new cases and severity of SARS-CoV-2 infection. PM can cause oxidative stress and inflammation in the respiratory system, and it plays a role in the expression of ACE-2 in respiratory cells.

Summary: This review discusses the importance of hand washing with soap and water for preventing the spread of SARS-CoV-2, including mechanisms of decontamination, contributions of soap components to cleansing and pathogen inactivation, importance of adherence to recommended contact times, potential effects of water temperature, differences between antimicrobial and basic soaps, comparisons with alcohol-based hand sanitizers, and advantages and limitations of different hand drying methods.

Droplets and aerosols: An artificial dichotomy in respiratory virus transmission

Yannis Drossinos et al.

Summary: The categorization of droplet and airborne transmission based on a cut-off droplet diameter may not adequately characterize the infectivity of droplets. The authors propose replacing droplet and aerosol transmission with a unique airborne transmission mode to better distinguish it from contact transmission.

Risk for Fomite-Mediated Transmission of SARS-CoV-2 in Child Daycares, Schools, Nursing Homes, and Offices

Alicia N. M. Kraay et al.

Summary: Fomites may serve as a significant source of transmission risk, especially in schools and child daycares. Combining surface cleaning, decontamination, and mask wearing can help mitigate this risk.

SARS-CoV-2 and Health Care Worker Protection in Low-Risk Settings: a Review of Modes of Transmission and a Novel Airborne Model Involving Inhalable Particles

X. Sophie Zhang et al.

Summary: This review examines the evidence on the mode of transmission of the novel coronavirus and appropriate personal protective equipment for healthcare workers in low-risk settings, proposing a broader definition of airborne transmission and emphasizing the importance of the nose as the main viral receptor site. Further studies, especially clinical trials, are needed to complete the picture.
