Dr. Colm Henry:

There was a blanket exercise in testing all patients - in the order, I think, of 30,000-odd - in nursing home facilities. That was carried out in April. To go back to what the test actually does, it provides information at a point in time. It tells one something about a particular time on a particular day; it does not tell one anything about the following day. What we will do in the next four weeks is serial testing of all healthcare workers, including all the disciplines the Deputy mentioned, in nursing home settings. This is to inform us in a deeper manner about the mode of transmission and the behaviour of this virus among healthcare workers, who have the power to transmit the virus while asymptomatic. That has potentially been an important source of transmission in a very vulnerable healthcare setting.
