• I've taken to wearing a mask in the last year, I always get sick after a long haul flight...

    I was under the impression that unless it’s a full on respirator, a mask would do nothing to stop the wearer catching things but rather stopped them spreading things?

  • Respirator with own independent air supply as aero air is recirculated air with a bit drawn in from the engines. But as you say it is to stop spreading disease as that is why doctors (medical staff) in operating theaters wear them.

    Might help if everyone is wearing masks...
