Link? How did they manage to do massive testing, when testing is just now becoming widely available?
Also, thats a very genetically homogenous population.
They were offering tests to anyone who wanted one, even if no symptoms. I think they had tested between 2,000 and 3,000 people. Population is only about 300,000 so the percentage is very large compared to USA tests. They have a better cross section of population compared to the USA where very sick people make up the majority of the population tested.
