OSHA guidance on cloth face coverings.

Helpful guidance in varying types of masks and materials based on scientific research.

May 2020 from the European Journal of Pediatrics. Both authors are professors of pediatrics and pediatricians. Esposito is an expert in infectious diseases. Principi is an expert in communicable diseases.
"Conclusion: On the basis of clinical findings, we think that the universal use of facial masks seems necessary when people have to go out in their everyday lives. In addition to the availability of masks of different sizes capable of adapting perfectly to the face, it is necessary that the use of masks in children is preceded by a strong parental work and school lessons on this issue and other hygiene topics with the main aim to obtain child cooperation."

From the International Journal of Environmental Research and Public Health.
This article is not specific to COVID-19 and assesses children's comfort and breathing abilities in 3 different brands of face masks as a potential protection from air pollution. However, it is one of the few research articles that pertains to children wearing masks.
“Twenty-four primary school children wore each facemask during a standardised walking and running activity. After each activity, the children were asked to rate facemask wearability in terms of parameters, such as perceived comfort, hotness, breathability and fit. At the end of the trial, the children compared and identified their preferred facemask. The main complaint about the facemasks was the children’s faces being too hot….The results show children’s perceptions of facemasks are highly affected by the facemask’s design, hotness and perceived breathability. By making children’s facemasks more appealing, breathable, cooler and improving their fit, wearability may be improved.”

Published in 2008 and evaluates the protective effect of masks. This study "assessed transmission reduction potential provided by personal respirators, surgical masks and home-made masks when worn during a variety of activities by healthy volunteers and a simulated patient."
The authors concluded: "Any type of general mask use is likely to decrease viral exposure and infection risk on a population level, in spite of imperfect fit and imperfect adherence, personal respirators providing most protection. Masks worn by patients may not offer as great a degree of protection against aerosol transmission."

Published in 2009 and evaluates how well masks would protect the person wearing it from infection.
"Adherence to mask use was associated with a significantly reduced risk of ILI (influenza-like illness)-associated infection. We concluded that household use of masks is associated with low adherence and is ineffective in controlling seasonal ILI. If adherence were greater, mask use might reduce transmission during a severe influenza pandemic."

Published in 2013 and specifically studies the use of homemade masks to control the spread of infection disease.
“Our findings suggest that a homemade mask should only be considered as a last resort to prevent droplet transmission from infected individuals, but it would be better than no protection.”

"We identified seasonal human coronaviruses, influenza viruses and rhinoviruses in exhaled breath and coughs of children and adults with acute respiratory illness. Surgical face masks significantly reduced detection of influenza virus RNA in respiratory droplets and coronavirus RNA in aerosols, with a trend toward reduced detection of coronavirus RNA in respiratory droplets. Our results indicate that surgical face masks could prevent transmission of human coronaviruses and influenza viruses from symptomatic individuals."

"Our aim was to provide visual evidence of speech-generated droplets and to qualitatively describe the effect of a damp cloth cover over the mouth to curb the emission of droplets."

This article focuses on pre-symptomatic and asymptomatic spread, which is something that masks can help prevent. A summary of this article is available at

"The purpose of this article is to demonstrate the science behind the wisdom of the recommendation to wear cloth face coverings or other appropriate masks when social distancing is not possible during a pandemic like COVID-19 where the disease is spread through respiratory droplets."
