What’s the population of Iceland?
There is talk of an aim to test 25000 a day here but currently only doing about a third of that, a lack of tests seems to be the major hold up.
300,000 or so. The most significant point though is that half weren’t showing symptoms. There could be potentially thousands of doctors and nurses still working, carrying the virus without symptoms and infecting patients and conversely thousands of others isolating at home because they’ve got a cough etc who could go back to work if they tested negative. If you don’t test you can’t fight the disease effectively.
