But there are higher risk settings, where transmission is possible in a shorter time interval, where health staff are dealing directly with known or suspected cases in particular settings and may need personal protective equipment. 

Figures from the Health Protection Surveillance Centre based on 6,444 cases of the virus up until midnight Tuesday 7 April show more than 1,700 healthcare workers in Ireland have contracted Covid-19.

This means healthcare workers account for 27.4% of all cases of the coronavirus diagnosed in here so far.
