The data released Friday confirms anecdotal evidence that eldercare facilities have become the major source of new infections in Italy, as elsewhere, given the vulnerability of residents and the lack of protective equipment for staff.
The next largest source of contagion from April 1-23 was among family members -- nearly 25 per cent -- collateral damage from Italy's seven-week stay-at-home order, the first and most extensive in the West.
Nearly 11 per cent of infections were traced to hospitals, 4.2 per cent at work and 2 per cent in religious communities.
Also, the average number of people who will get COVID-19 from a single infected person -- the so-called R0 -- is now under 1 nationwide for the first time, according to the report.
It started out between 2-3 in hard-hit parts of the north, where the epicenter of Europe's pandemic erupted on Feb. 21.
Stefano Merler of the Bruno Kessler Foundation, who analysed the data, says even though Italy's lockdown had brought the R0 down to an average of 0.2-0.7 nationwide, "we're still not in a situation of security."
Virologists say Italy couldn't consider re-opening until the R0 is well under 1, while adding that it won't reach 0 until there is a vaccine. (AP) INDIND
