Dr. Tony Holohan:

I will respond to the latter question first and then Dr. Glynn might come back on the question about long Covid in a moment.

There is a weekly survey ongoing. We are looking, as we speak, at the question of the periodicity of that and whether we need to keep that going weekly at this point in time. It is just another feature of all the measures we have in place that we might need to look at. We look at many features of the response, the public attitude to the disease, the level of worries, the views on restrictions and whether people feel that further or fewer restrictions are needed. Those are general questions we have asked all the way through the pandemic. Then, from time to time, we ask more specific and focused questions that might be relevant to a particular set of measures at a point in time. That is where we have been looking more closely at antigen tests and these behaviours. I will give the Senator the precise data because I did not have them in front of me when I spoke to this subject earlier. For the most recent week for which we have data, which was the survey done on Monday of this week, 31 January, 30% of adults said they had taken an antigen test in the past week. Some 14% of the population told us they had symptoms consistent with Covid in the previous week. Of those 14% who took an antigen test and received a negative result, 8% went on to arrange a PCR test and only 22% reported that they self-isolated, which is very low. Therefore, of those people who had symptoms, who then got an antigen test and received a negative result, only one in five of them, in effect, self-isolated. That number has dropped. The number reporting that they had self-isolated was a good deal higher a number of weeks ago. We have tracked that as one important measure. That is what I was referring to briefly earlier. I am happy to give Senator Conway a copy of the full set of questions. We can arrange to make that available to the committee and Senator Conway if that would be of interest.
