in a Pandemic the places are not all the same: the news says so and I Dpcm. In practice, there are environments more dangerous than others, the so-called “super diffuser” places. They are slaughterhouses, private parties or funeral but also prisons or, for some, transportation and they have a statistical impact on the spread of the coronavirus more than others. It is clear that places cannot be blamed for this, the four walls themselves do not have particular responsibilities, but unfortunately some behaviors or intrinsic characteristics of the activities they host make them less safe.

The most emblematic case is undoubtedly that of slaughterhouses. Around the world, especially in the United States and Germany, but also in Italy and even recently, there have been hundreds of closures since the beginning of the emergency. COVID-19 of the factories where the carcasses are processed for food use: for no apparent reason, in fact, they had become an outbreak. After months of trying to refine the protocols and toughen the rules, with someone who also got rid of the meat, considering it a vehicle of contagion, an Italian study conducted in Puglia by the newly elected virologist Pier Luigi Lopalco, however, clarified the problem. . The cause is attributable to the cold of the cells and the humidity, which lower the immune defenses of the operators. Intrinsic characteristics that must be opposed with common sense, respecting distances and wearing a mask but which, by not being able to stop completely under pain of blocking supplies, make a place like slaughterhouses a “super diffuser”.
The same occurs, for example, with churches, particularly those in America, where the presence of very numerous choirs (singing inevitably involves the emission of dangerous droplets) has led them to become vast basins of contagion. So much so that even the closure of La Scala in Milan a few days ago was caused by an internal outburst that had the singers as the main protagonists. But also, unfortunately, to bring some examples even closer to this side of the Atlantic, in prisons. That Italians do not guarantee adequate living spaces for prisoners is certainly not new, and much less during a pandemic in which, to avoid contagion, it is necessary above all to stay spaced. In addition, it is often impossible to have environments in which to isolate positive or new guests who have just arrived from the outside. And the same is true of stadiums that, even outdoors, are home to a high density of people who speak loudly, shout or sing. Imagine yourself in a closed environment such as discos, with the multiplier effect caused by the fact that many times in these contexts the mask is lowered, which can happen.
The absence of masks, for example, is one of the main factors to take into account when talking about restaurants or other administration activities (or dinners organized at home). Therefore, beyond the irony, the fact of closing them at 18 is not due to a link between time and the spread of the virus. As for the fact that at lunch more than at dinner, meals are usually more composed, formal, often functional. The same combination of behaviors and characteristics of the environment that has led, for example, to demonstrate that the infection is particularly ‘easy’ only when it comes to a certain type of gyms, those that have group classes. For example, in South Korea, a high intensity Zumba lesson in confined spaces sparked a chain of infections in the city of Cheonan with 112 confirmed cases of Covid. The same could be said of transport, however, where the key is the ventilation of the vehicles, or of the classrooms: the difference is the behavior. Strongly recommending adherence to the guidelines cannot be enough. On the other hand, if Japan has cut the transmission rates of the virus by keeping parks and public stadiums open, it is because both in the first and in the second it is mandatory to remain silent.
