Is there any guidelines currently on reducing the risk for pregnant healthcare staff? I've looked on the NHS and RCOG but it's a bit vague - talks about "reducing risk after 28 weeks" but is that indicating that roles should actually be altered? I work in an area where I'm required to do aerosol generating procedures on multiple patients in a day, and whilst I'm not 28 weeks yet I would like to know if I should be asking my employer to review / allow me to stop this aspect of my job when I get there, or if I have no grounds for asking them to modify?
