   This video demonstrates how well fit-tested respirators work as source control vs no masks vs loose fitting medical masks.
   No complicated modelling required.
   We can achieve higher levels of risk reduction by having our healthcare workers wear these when looking after vulnerable patients, particularly at times where staff are at higher risk of infection (recently symptomatic, close contact of someone unwell at home, or high community prevalence)
