I gather that whatever number of reported and confirmed cases there are, there is an X number of other likely cases. At one stage there was a suggestion that there could be as many as four times the number of cases as those that had been confirmed. Do we have a sense of what the X number is now? In other words, how many cases of Covid-19 have there been that we do not know about but that we can make assumptions on or that the evidence would point towards?
