Abstract

COVID-19 is a disease which is sweeping the globe, often with devastating consequences. The more we understand, the more it appears that infection has a very wide clinical spectrum from totally asymptomatic to life threatening. Without widespread community testing it is impossible to ascertain true infection rates and develop strategies which reduce or prevent transmission without the need for on-going draconian measures such as complete national lockdown. These measures are mandatory at the time of writing, however widespread adoption of face masks has been shown to help prevent transmission of other respiratory pathogens, and also infections acquired by healthcare staff. Combining mass testing with a combination of social distancing and face mask use might offer a way forward until a mass COVID-19 vaccination programme can be established.
