For some time, Dr No has been bothered by the fact that some people with covid continue to have positive PCR tests long after they can be considered ill and infectious. These people, the long distance shedders, will, because of the way cases are defined and counted, appear as cases, even when clearly they are not cases. They will themselves suffer the loneliness of imposed but pointless self-isolation, but they will also inflate the apparent size of any covid wave, and in so doing aggravate alarm and panic, despite the fact that aggravation is unfounded, because they are not cases, nor are they infectious. In short, every covid wave is inflated, and the question for today is: by how much does the way we count covid cases inflate our estimate of the number of true cases?
