Results: Whilst using FRSMs, HCWs working on red wards faced an approximately 31-fold
(and at least 5-fold) increased risk of direct, ward-based infection. Conversely, after changing
to FFP3 respirators, this risk was significantly reduced (52-100% protection).
Conclusions: FFP3 respirators may therefore provide more effective protection than FRSMs
for healthcare workers caring for patients with COVID-19, whether or not AGPs are
undertaken. #bettermasks#P3

Face #mask rules: compulsory coverings in shops, fines and who is exempt from wearing one

2/6 What counts as a face covering - and what are the options?
From home-made versions crafted out of hoover bags and panty liners (yes, really) to bandanas that transform even the most genteel Home Counties shopper to roadside bandit
3/6 Surgical Masks: The most common design that everyone clambered to buy from Amazon in the early days of lockdown. Effective to a point, protecting the wearer against large droplets although not so much with airborne particles due to the loose fit.
