Italy Update 6 April
1,941 new, active cases (currently positive) on 30,000 tests administered.
636 deaths. Still in decline, but slow.
1,022 recovered
Total number of those hospitalized declined again, and those in critical care (ICU) declined slightly for third day in a row. Increase of nearly 2,000 who are under home quarantine without symptoms or with only mild symptoms.
Newspapers are reporting that three different studies estimate that 5-6 million people in Italy (on Italian out of 10) is or has been infected with the virus. This is said to be critical to determine the conditions for when and how to restart the economy with a gradual easing of the lockdown. If these estimates are correct, they are seen to be too low to present any herd immunity and too high to relax current lockdown efforts. According to news reports, the estimates are consistent with studies conducted by Chinese universities that estimated one out of 10 people were infected in Hubei province (and some of the studies estimate 1 in 4).
One thing to consider in looking at the numbers in this thread, like the ones below, are the stark differences in positive results and tests administered in different regions. Italy's lockdown is national, but the healthcare systems are administered within these regions. Note the very different different rates of testing ("tamponi" - gray column at right) vs the total cases (orange column). The Veneto region was not overwhelmed by the COVID-19 cases as was the Lombardy region.
