Perspex screens may increase Covid-19 transmission risk if wrongly positioned

Sage experts said there may be benefits to using screens or barriers in certain situations 

Perspex screens in workplaces may actually increase the risk of virus transmission if they are placed in positions that block airflow or cause poor circulation, scientists advising the UK Government have warned.

In an undated document released on Friday by the Scientific Advisory Group for Emergencies (Sage), the experts said there is very little overall evidence on the effectiveness of these barriers at reducing infection transmission through droplets.
