Good news - one small Italian town, Vo Euganeo, has completely stopped its outbreak by rigorously testing everyone in the community including those who were asymptomatic. To do that they disregarded a directive from their government to only test those who had symptoms.

Even China didn’t do that, or Singapore. They only tested those with fever or respiratory disease symptoms.

Vo Euganeo is in Veneto which has had consistently lower case numbers than the other provinces and has had the most rigorous approach to case finding.

With their first test they found that 3 percent tested positive (that would be about 90 out of 3300). After 2 weeks lockdown they tested again and only 0.3% tested positive (that would be 9 cases approx) and they have had no new cases for days.

“the lesson we learned is that isolating all positive cases, whether they were sick or not, we were able to reduce transmission by 90 percent and we found that all those who were still positive were all without symptoms” The hard lessons of Italy's devastating coronavirus outbreak.

Talking about what they did on Italian TV:

"No war was won only by creating hospitals, the weapons to win are quarantine, containment and active surveillance." Starting from the hospital in Padua where “following the Chinese example, we immediately checked all the staff and patients to prevent anyone who entered from infecting anyone else or becoming infected. It is our merit, even if we have disregarded the ministerial directives that did not allow to carry out tests on asymptomatic drugs ”. Then they used the same strategy in Vò Euganeo: "We took swabs from everyone from the first moment, discovering that 3% of the population was positive, but that more than half had no symptoms". The isolation of asymptomatics meant that two weeks later: “the number of positives has gone from 3% to 0.3% or a reduction of 90%. If we had these numbers all over Italy, we would have a party ”. Veneto's strategy now is to extend the samples as much as possible: “Our goal is to go from 1500 to 5000 tests in a week. If we don't identify cases one by one, we won't eliminate the disease . " Coronavirus, virologist Crisanti: “New hospitals? War is not won only in this way. To eliminate the disease, asymptomatic diseases must also be identified "

This is in Italian, but you can switch on subtitles then go to auto translate to see the subtitles in English. It doesn’t say much just that 90% reduction figure but may be of interest.
