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.
