Two days ago, we saw in the Herald, from the not really widely respected, bacteriologist/ virologist/ political activist:
Professor Hugh Pennington, emeritus professor of bacteriology at Aberdeen University, gave evidence to Holyrood’s health and sport committee – criticising leaders for “not putting enough emphasis on testing”.
Then, today, we read:
Earlier this month, South Korea’s health chiefs reported the puzzling – and potentially troubling – cases of 91 patients who appeared to have recovered from the infection only to test positive again later. It is unclear exactly why this happened but a ‘relapse’ rather than a re-infection has been suggested. There is evidence the virus may lie dormant at undetectable levels in human cells before potentially ‘re-activating’. Another explanation are false negatives. Conventional coronavirus tests can give the wrong result 20 to 30 per cent of the time, and are especially prone to error when a person is asymptomatic.
Those models of the testing, testing, testing, school of thought, Germany and South Korea, are beginning to see worrying signs of relying on them as the basis for further steps.
Imperfect no doubt, but is the Scottish Government’s wider strategy of prioritising the testing of key-workers, distancing and a strict lock-down followed by very careful adjustments, turning out to be not-so-daft after all?
