My Lords, the PCR test is very sensitive. Most people who take the test are presenting a symptom, so a very high proportion of those positives are people who have the disease when they take it. Of course, there are many who have the disease and do not take a test at all, so there is more disease in the population than accounted for in the positive tests. There is a very small proportion of people who might have shreds of the virus from a previous infection who then test positive, but it is thought that that proportion is very small.
