Facemasks for Public Use

Bulletin 39 | Nicola Oliver

The use of face masks by the general public for personal and wider protection has been

recommended in many countries, to the extent that in some, fines are imposed for non-compliance.

This bulletin reviews the current evidence-base for mask wearing by the public in an effort to keep R below 1.

Most of the evidence points in the same direction: mask wearing reduces person-to-person

transmission and could form part of a strategy that reduces the risk of transmission from

asymptomatic carriers and potentially reducing viral load on the uninfected.
