Financial Times on novel and successful approach to coronavirus containment in small Italian city

Here's the lede from the story by Donato Paolo Mancini and Clive Cookson in the Financial Times on March 17, 2020: 

An infection control experiment that was rolled out in a small Italian community at the start of Europe’s coronavirus crisis has stopped all new infections in the town that was at the centre of the country’s outbreak. Through testing and retesting of all 3,300 inhabitants of the town of Vò, near Venice, regardless of whether they were exhibiting symptoms, and rigorous quarantining of their contacts once infection was confirmed, health authorities have been able to completely stop the spread of the illness there. 

Andrea Crisanti, an infections expert at Imperial College London who is taking part in the Vò project while on sabbatical at the University of Padua, urged countries that have been limiting virus testing, which includes the UK and US, to learn lessons and ramp up the numbers of people being screened. “In the UK, there are a whole lot of infections that are completely ignored,” Prof Crisanti told the Financial Times. “We were able to contain the outbreak here because we identified and eliminated the ‘submerged’ infections and isolated them,” he said of the Vò approach. “That is what makes the difference.”

In other words, broad testing was effective in that context. This seems like the sort of experiment that would be hard to do in a larger population cluster, if only because it would be more costly and harder to control the movement of people to and from the place.
