The reopening of schools for a few days before Easter it was just a “symbolic item.” But that could cost us dearly. As he explains Fabrizio Pregliasco, Researcher of General and Applied Hygiene at the University of Milan, although “from the didactic point of view for students, obviously nothing changes, from the point of view of health, however, it adds more risks to an already delicate epidemiological situation “.
Vaccino, Galli: “Still defenseless of the English variant, there have been cases of reinfection”
Based on what scientific evidence do you think it is safe to bring students back to class?
“It was a response to a need, since distance education creates objective problems for families. But from a scientific point of view to date we believe that school is an element of risk ”.
Recently, a study was published in the Lancet Regional Health – Europe in which some researchers claim otherwise, however.
“Actually, that study has inherent characteristics of weakness with respect to how it was constructed. The observation period essentially stops at the beginning of the second wave, therefore it is too early to draw conclusions. Also, consider several schools where, in some cases, tampons have not been manufactured. And this adds uncertainty to the main problem that exists today, namely the difficulty of tracking and the inability to trace the chain of contagion. We believe that many times we are not able to connect the school as an element of the beginning of an outbreak ”.
So schools reopen even though we know there is always the risk of contagion.
“We already know the role of the school in the spread of the epidemic and it can also be related to the fact that, despite following all the protocols, we are unable to adequately control the mobility and sociability that is created around us. Instead of reopening, these days could allow for a more systematic reprogramming and implementation of security protocols.
So will grandparents pay the costs again?
“Unfortunately, it will be difficult to determine how many infections this reopening will cause. And it is a terrible doubt. We remember that we are in a period of great spread of the virus, we are probably witnessing a plateau phase, although unfortunately we cannot adequately quantify all cases, so we certainly lose a part. In recent weeks, a 3-4 percent reduction in infections has been seen, but debt for pain and mortality remains very high. For this reason, from a scientific point of view, a blockade should, unfortunately, still continue.
But if scientific evidence often takes a backseat, how can the epidemic be kept at bay once and for all?
“The fundamental effort in this period is to keep the spread of the virus as low as possible and ensure that it can be implemented in the short term. But a vaccination campaign is urgently needed to reduce the already heavy impact of infections. ‘
Given the lack of anticovide doses, the road still seems to be uphill.
Surely the slowness in the implementation of the vaccination campaign, as the WHO has highlighted, can facilitate the appearance of variants and make the curve go less, especially in the most complex cases. In the situation in which we find ourselves, the school is also an element of possible risk situations. So it still needs a squeeze and special attention before reopening. And then, it is necessary to invoke a personal responsibility, regardless of the provisions. Given that at this time any human contact should be considered a potential risk of contagion, we must drink it and use it with common sense.
