While waiting to understand how much the reopening of schools can affect the progress of the epidemic, one of the most effective weapons to stop the spread of the virus remains contact tracing.
“ASL virus hunters employed in contact tracing – we read – succeeded in initiating at-risk contact tracing in 100 percent of cases. And this with 1.4 tracking workers per 10 thousand inhabitants, a team above the minimum reference standard that is one. “However,” the disadvantage is that for 207 tested positives out of 546 during the week, it was not possible to trace the origin of the infection”.
“And it is a big problem – explains Antonio Miglietta, infectious doctor, head of the epidemiology service of ASL Roma 2 – because that means leaving contagious people in circulation who don’t know they are. But it is not our fault, but of those who do not respect the rules. . How do you trace the contacts of those who expose everyone to risk because they never wear a mask and don’t respect any of the basic rules? ”.
