COVID-19 pandemic illuminates the importance of airborne transmission of respiratory viruses

SARS-CoV-2, the virus behind today's global coronavirus pandemic, spreads primarily by inhalation of virus-laden aerosols at both short and long ranges - and a comprehensive new assessment of respiratory viruses finds that many others probably do as well.

Predictability of single symptom screening for pediatric SARS-CoV-2 infections

A new study on the preprint server medRxiv* discusses the predictive value of single symptom-based screening to confirm pediatric SARS-CoV-2 cases.

A systematic review of in vitro studies evaluating the efficacy of mouth rinses on SARS-CoV-2

A new study aims to evaluate the current body of published in vitro research related to the efficacy of mouthwashes in preventing SARS-CoV-2 transmission.

Millions of Africans are at risk of contracting COVID-19 due to lack of public health tools

Millions of people across the African continent are at risk of contracting COVID-19 because of a lack of the most basic public health tools to protect themselves - including the essentials of soap and water.

Direct evidence in hamsters shows SARS-CoV-2 is airborne

Evidence suggests that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can be transmitted without contact by respiratory droplets and aerosols bearing the virus when coughing, sneezing, speaking, and breathing. The virus has been cultured from aerosols collected nearby COVID-19 patients, and such aerosols can linger in still air for hours.

How SARS-CoV-2 vaccination symptoms differ from early COVID-19 symptoms

A new study published on the preprint server medRxiv* presents an analysis of the differences between recorded vaccination side effects vs. early COVID-19 symptoms. The researchers focused on four vaccines, namely, Pfizer-BioNTech (PB) mRNA (BNT162b2) vaccine, based on messenger ribonucleic acid encoding the viral spike protein; the Moderna mRNA (mRNA-1273) vaccine; the Oxford-AstraZeneca (O-AZ) adenovirus-vectored vaccine; and the Janssen adenovirus-vectored Ad26.COV2.S).

Human coronaviruses need organic materials to transfer efficiently between surfaces

This study, published in the journal Viruses, indicated that human coronaviruses do not transfer effectively from contaminated hands to contact surfaces without the presence of any organic material.

New substance derived from Saussurea controversa exhibits osteoprotective properties

Metabolic bone diseases, including osteoporosis, when bones lose their mass and become so fragile that they could be damaged while sneezing or under little stress, are called the silent epidemic of the 21st century.

Iodine derivative kills SARS-CoV-2 within 90 sec

A recent study estimated the virucidal efficacy of EID for oral/nasal decontamination of known or suspected cases of COVID-19.

Study may lead to electrical stimulation implants that restore intraoral functions

Even the mundane act of swallowing requires a well-coordinated dance of more than 30 muscles of the mouth. The loss of function of even one of these, due to disease or injury, can be extremely debilitating. For these people, nerve stimulation offers a ray of hope to regain some of their lost oral function.

Researchers explain how air turbulence create potentially virus-laden droplets

Computer simulations have been used with great success in recent months to visualize the spread of the COVID-19 virus in a variety of situations.

Researchers identify the best masks for blocking respiratory droplets

During the COVID-19 pandemic, cloth face masks became a way to help protect yourself and others from the virus. And for some people, they became a fashion statement, with many fabric choices available.

FDA approves antihistamine nasal spray for over-the-counter use

The U.S. Food and Drug Administration today approved a nasal antihistamine for nonprescription use through a process called a partial prescription to nonprescription switch.

Researchers identify specific cells and proteins that control the sneeze reflex

A tickle in the nose can help trigger a sneeze, expelling irritants and disease-causing pathogens. But the cellular pathways that control the sneeze reflex go far beyond the sinuses and have been poorly understood.

Long-range airborne transmission of SARS-CoV-2

In an early release copy of a short commentary paper recently published in the Canadian Medical Association Journal by Addleman et al. (June 8th, 2021), the impact of, and possible solutions to, the short- and long-range airborne transmission of SARS-CoV-2 are explored.

HEPA air purifier can significantly reduce airborne COVID-19 particles

As COVID-19 restrictions ease nationwide and more people host indoor gatherings, investing in a high efficiency particulate air (HEPA) purifier might not be a bad idea, says a University of Cincinnati College of Medicine researcher.

Normal breathing without mask can transport saliva droplets to more than 7 feet

The World Health Organization and the Centers for Disease Control recommend keeping a certain distance between people to prevent the spread of COVID-19. These social distancing recommendations are estimated from a variety of studies, but further research about the precise mechanism of virus transport from one person to another is still needed.

Surgical masks effectively reduce outgoing airborne particles, despite leakage at edges

A new study from the University of California, Davis and the Icahn School of Medicine at Mount Sinai confirms that surgical masks effectively reduce outgoing airborne particles from talking or coughing, even after allowing for leakage around the edges of the mask. The results are published June 8 in Scientific Reports.

Masks and physical distancing could reduce SARS-CoV-2 spread to 1% among essential food plant workers, says study

The food supply is an essential service. Yet, workers in this industry are at high risk of acquiring infection with the novel coronavirus in their workplace unless proper mitigation measures are put in place. A new study, released as a preprint on the medRxiv* server, shows that the risk of infection may be reduced to less than 1% with proper precautions.

New testing technology can accurately differentiate between viral and bacterial infections

When patients complain of coughing, runny nose, sneezing and fever, doctors are often stumped because they have no fundamental tool to identify the source of the respiratory symptoms and guide appropriate treatments.
