Facemasks are recommended for diseases transmitted through droplets and respirators for respiratory aerosols, yet recommendations and terminology vary between guidelines. The concepts of droplet and airborne transmission that are entrenched in clinical practice have recently been shown to be more complex than previously thought. Several randomised clinical trials of facemasks have been conducted in community and healthcare settings, using widely varying interventions, including mixed… 
Facemasks and similar barriers to prevent respiratory illness such as COVID-19: A rapid systematic review
TLDR
It is concluded that wearing facemasks can be very slightly protective against primary infection from casual community contact, and modestly protective against household infections when both infected and uninfected members wear facemask.
Community use of face masks and similar barriers to prevent respiratory illness such as COVID-19: a rapid scoping review
TLDR
It is important to balance evidence from RCTs and observational studies when their conclusions widely differ and both are at risk of significant bias, and to recommend improvements to this evidence base.
Selection and Use of Respiratory Protection by Healthcare Workers to Protect from Infectious Diseases in Hospital Settings.
TLDR
HCWs should be aware of infection control policies and training should be provided on the correct use of respiratory protective devices, however, HCWs require adequate training on storage, use, and cleaning of PAPRs.
Effectiveness of Mask-Wearing on Respiratory Illness Transmission in Community Settings: A Rapid Review.
TLDR
Masking in community settings decreases transmission of influenza-like illness and laboratory-confirmed respiratory infection andMask-wearing combined with enhanced hand hygiene reduces transmission of flu virus transmission in community setting.
Medical mask or N95 respirator: When and how to use?
TLDR
Although the main transmission route for COVID-19 is droplets, during aerosol generating procedures airborne transmission may occur, and personal protective equipments and especially masks were among the hottest topics during this pandemic.
A technical review of face mask wearing in preventing respiratory COVID-19 transmission
COVID-19 in Dental Practice: Transmission Risk, Infection Control Challenge, and Clinical Implications
TLDR
Dental care providers are at high risk due to the nature of their profession, which necessitates close proximity to the patient's oropharyngeal region and the use of droplet and aerosol-generating procedures, and should be aware of the recently updated knowledge about COVID-19 modes of transmission and recommended infection control measures in dental settings.
Prevalence and Acceptance of Face Mask Practice among Individuals Visiting Hospital during COVID-19 Pandemic: An Observational Study
TLDR
Extensive use of facemasks coupled with environmental hygiene measures is a public health strategy which can help to mitigate the COVID-19 epidemic impact, however, a targeted comprehensive strategy to improve compliance to proper facemask practice among the high-risk population is needed to achieve maximal protective benefit.

Facemasks and Hand Hygiene to Prevent Influenza Transmission in Households
TLDR
A cluster randomized trial to test whether improved hand hygiene or surgical facemasks reduce the transmission of interpandemic influenza in households found that healthy family members started using these measures within 36 hours of symptom onset in an infected family member.
Facemasks, Hand Hygiene, and Influenza among Young Adults: A Randomized Intervention Trial
TLDR
Face masks and hand hygiene combined may reduce the rate of ILI and confirmed influenza in community settings and these non-pharmaceutical measures should be recommended in crowded settings at the start of an influenza pandemic.
Mask use, hand hygiene, and seasonal influenza-like illness among young adults: a randomized intervention trial.
TLDR
It is suggested that face masks and hand hygiene may reduce respiratory illnesses in shared living settings and mitigate the impact of the influenza A(H1N1) pandemic.
Professional and Home-Made Face Masks Reduce Exposure to Respiratory Infections among the General Population
TLDR
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.
Face masks to prevent transmission of influenza virus: a systematic review
TLDR
There is some evidence to support the wearing of masks or respirators during illness to protect others, and public health emphasis on mask wearing during illness may help to reduce influenza virus transmission.
The role of facemasks and hand hygiene in the prevention of influenza transmission in households: results from a cluster randomised trial; Berlin, Germany, 2009-2011
TLDR
Results suggest that household transmission of influenza can be reduced by the use of NPI, such as facemasks and intensified hand hygiene, when implemented early and used diligently.
A randomized clinical trial of three options for N95 respirators and medical masks in health workers.
TLDR
Continuous use of N95 respirators was more efficacious against CRI than intermittent use ofN95 or medical masks and resulted in significantly lower rates of bacterial colonization, a novel finding that points to more research on the clinical significance of bacterial infection in symptomatic HCWs.
Surgical Mask to Prevent Influenza Transmission in Households: A Cluster Randomized Trial
TLDR
This study evaluated the effectiveness of facemask use by index cases for limiting influenza transmission by large droplets produced during coughing in households in France during the 2008–2009 influenza season and found no evidence of effectiveness.
