Variability in expiratory trajectory angles during consonant production by one human subject and from a physical mouth model: Application to respiratory droplet emission.

Indoor Air 2021 Jul 23. Epub 2021 Jul 23.

Department of Mechanical and Aeronautical Engineering, Clarkson University, Potsdam, New York, USA.

The COVID-19 pandemic has highlighted the need to improve understanding of droplet transport during expiratory emissions. While historical emphasis has been placed on violent events such as coughing and sneezing, the recognition of asymptomatic and presymptomatic spread has identified the need to consider other modalities, such as speaking. Accurate prediction of infection risk produced by speaking requires knowledge of both the droplet size distributions that are produced, as well as the expiratory flow fields that transport the droplets into the surroundings.

Role of Threat and Coping Appraisal in Protection Motivation for Adoption of Preventive Behavior During COVID-19 Pandemic.

Front Public Health 2021;9:678566. Epub 2021 Jul 5.

World Health Organization RNTCP Technical Support Network, Swasthya Bhawan, Kolkata, India.

With more than 100 million cases and over 2 million deaths globally, the COVID-19 pandemic continues to remain a major threat. Identifying the behavioral factors influencing preventive behaviors for COVID-19 are crucial in devising public health policies to promote essential strategies to combat the pandemic in an efficient manner. The current study was therefore conducted to estimate the prevalence of COVID-19 preventive behaviors and measure their association with behavioral constructs like threat perception, response efficacy, and self-efficacy, as per socio-demographic background.

Bioaerosols from mouth-breathing: Under-recognized transmissible mode in COVID-19?

Can Commun Dis Rep 2021 Jun 9;47(56):276-278. Epub 2021 Jun 9.

Department of Oral Medicine & Radiology, SRM Kattankulathur Dental College & Hospitals, SRM Institute of Science and Technology, Chennai, India.

The whole world has been affected by the coronavirus disease 2019 (COVID-19) pandemic, and many researchers are racing to understand the disease course and to undertake risk analyses to formulate effective treatment strategies. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is highly transmissible through coughing and sneezing, and through breathing and talking which may account for viral transmission from asymptomatic carriers. Bioaerosols produced during mouth-breathing, an expiratory process in habitual mouth breathers, should be considered in addition to nasal bioparticles as a potential transmissible mode in COVID-19.

The spread of macroscopic droplets from a simulated cough with and without the use of masks or barriers.

PLoS One 2021 5;16(5):e0250275. Epub 2021 May 5.

The Blake High School, Minneapolis, Minnesota, United States of America.

One of the main challenges during the COVID-19 pandemic is the lack of safety measures and guidelines to reduce the risk of viral spread among people during gatherings. This study was conducted to evaluate the distance of oral and nasal droplet spread in a model that simulates coughing and sneezing in a public setting, specifically a school setting, to guide faculty and staff members with safety measures and guidelines to reduce droplet spread. Several models were prepared to observe and visualize the spread of fluid simulating respiratory droplets in places such as the classroom and the cafeteria, in which a student would be more susceptible to contract a virus since individuals cannot wear masks while eating.

al-Farabi Kazakh National University, Almaty, Republic of Kazakhstan.

The spread of the novel coronavirus disease (COVID-19) continues to show that geographic barriers alone cannot contain the virus. Asymptomatic carriers play a critical role in the nature of this virus, which is rapidly escalating into a global pandemic. Asymptomatic carriers can inadvertently transmit the virus through the air stream. Read More

Spirometry during the SARS-CoV-2 pandemic. Guidelines and practical advice from the expert panel of Respiratory Physiopathology Assembly of Polish Respiratory Society.

Adv Respir Med 2020 ;88(6):640-650

2nd Department of Respiratory Medicine, Institute of Tuberculosis and Lung Diseases, Warsaw, Poland.

At the end of 2019, in Wuhan, the Hubei Province's capital city in China, the first cases of COVID-19 disease caused by the novel coronavirus, SARS-CoV-2, were described. The rapid spread of the infection through the world resulted in the World Health Organization announcing the COVID-19 a global pandemic in March 2020. The main routes of transmission of the novel coronavirus SARS-CoV-2, according to current evidence, are via droplets inhalation, direct contact with contaminated surfaces, and transmission via the mucous membranes of the mouth, nose, and eyes, and probably through airborne particles from the respiratory tract, generated during coughing and sneezing of infected individuals.

Department of Chemistry, University of Kentucky, Lexington, Kentucky, USA.

The fast spread of coronavirus disease 2019 (COVID-19) constitutes a worldwide challenge to the public health, educational and trade systems, affecting the overall well-being of human societies. The high transmission and mortality rates of this virus, and the unavailability of a vaccine or treatment, resulted in the decision of multiple governments to enact measures of social distancing. Such measures can reduce the exposure to bioaerosols, which can result in pathogen deposition in the respiratory tract of the host causing disease and an immunological response. Read More

School of Mechanical and Manufacturing Engineering, UNSW Sydney, Kensington, NSW 2052 Australia.

Abstract: Respiratory activities such as sneezing generate pathogen laden droplets that can deposit in the respiratory tract of a susceptible host to initiate infection. The extent of spread of these droplets determines the safe distance between a patient and health care worker. Here, we have presented a method to visualize the droplets expelled by a sneeze using light-sheet illumination. Read More
