Simple protective behavioural changes, namely physical distancing, face-mask use & eye protection, are associated with a significant risk reduction in coronavirus transmission.

SARS-CoV-2 viral particles can travel large distances, detected at up to 4 meters, and remaining in air up to 3 hours after aerosolisation, although with uncertain infective viability.

Meta Analysis Comparative Study
Effectiveness of N95 respirators versus surgical masks against influenza: A systematic review and meta-analysis.
Previous meta-analyses concluded that there was insufficient evidence to determine the effect of N95 respirators. We aimed to assess the effectiveness of N95 respirators versus surgical masks for prevention of influenza by collecting randomized controlled trials (RCTs). ⋯ The use of N95 respirators compared with surgical masks is not associated with a lower risk of laboratory-confirmed influenza. It suggests that N95 respirators should not be recommended for general public and nonhigh-risk medical staff those are not in close contact with influenza patients or suspected patients.

Meta Analysis Comparative StudyMedical masks vs N95 respirators for preventing COVID-19 in healthcare workers: A systematic review and meta-analysis of randomized trials.
Respiratory protective devices are critical in protecting against infection in healthcare workers at high risk of novel 2019 coronavirus disease (COVID-19); however, recommendations are conflicting and epidemiological data on their relative effectiveness against COVID-19 are limited. ⋯ Low certainty evidence suggests that medical masks and N95 respirators offer similar protection against viral respiratory infection including coronavirus in healthcare workers during non-aerosol-generating care. Preservation of N95 respirators for high-risk, aerosol-generating procedures in this pandemic should be considered when in short supply.
