I will ask a brief follow-up question about testing. There has been a lot of discussion, particularly on social media, about PCR testing. Some international doctors are claiming that the number of cycles used in a PCR test means that a person can be shown to be positive if he or she had the virus some time ago but are no longer symptomatic. Equally, I have spoken to Irish doctors who have said that they are more concerned with false negatives than false positives. Would Dr. Henry comment on that?
