The World Health Organisation (WHO) advises governments around the world to apply a “risk-based approach” and consider different factors – such as feasibility and the risk of exposure – before deciding whether to adopt the use of face masks or not.
There’s a difference between masks which are used in a clinical setting for doctors, nurses, care home workers and face coverings – the kind of DIY cloth mask that someone might put together at home.
In relation to face coverings, they can provide an incremental mitigation of the risk of transmission to other people.
- People who use public transport or visit shops should consider covering their mouth and nose based on advice from SAGE
- Face coverings are not a replacement for social distancing and regular handwashing which remain the most important actions, says Chief Medical Officer
- Public urged not to buy medical grade masks so they can be saved for frontline health and care workers, and instead make their own face coverings at home
The public is advised to consider wearing face coverings in enclosed public spaces where you may be more likely to come into contact with people you do not normally meet, the government announced today.
After careful consideration of the latest scientific evidence from the Scientific Advisory Group for Emergencies (SAGE), the government confirmed face coverings can help reduce the risk of transmission in some circumstances.
Face coverings can help us protect each other and reduce the spread of the disease if you are suffering from coronavirus but not showing symptoms. People with coronavirus symptoms, as well as members of their household, should continue to follow the advice to self-isolate.
They may be beneficial in places where it is hard to follow maintain social distancing measures. This applies when using public transport, such as trains, buses and metro systems,….
Please note in the UK 2m social distancing is currently recommended
Making A Facial Covering
Facial coverings not medical masks are currently advised in the UK. The WHO information is provided to give some guidance that may apply to facial coverings
Using A Mask
- Before putting on a mask, clean hands with alcohol-based hand rub or soap and water.
- Cover mouth and nose with mask and make sure there are no gaps between your face and the mask.
- Avoid touching the mask while using it; if you do, clean your hands with alcohol-based hand rub or soap and water.
- Replace the mask with a new one as soon as it is damp and do not re-use single-use masks.
- To remove the mask: remove it from behind (do not touch the front of mask); discard immediately in a closed bin; clean hands with alcohol-based hand rub or soap and water.
