Dr. Tony Holohan:

With the prevalence of the disease, as it stands in this country at the moment, we have about 0.1%. We have looked at a number of different publications. The recently publication by the Infectious Disease Society of America was referred to, which talks about these tests not being reliable in a prevalence of less than 5%. That is what our data is telling us. We cannot rely on the test at this low level of prevalence so I am just not clear what one would be testing, and testing one flight in that situation, where the probability, on a flight of 150 people, of anybody being infected is very, very low.
