The Sars Cov variant 2 identified in Great Britain, Denmark, Australia, the Netherlands and now also in Italy, is creating alarm about the possible effects on the population. The risk of meetings or even contacts without the necessary distancing measures could drive the epidemic out of control. If the possibility of contagion is so high, what can happen? Is the danger of getting infected in public places greater? Are there more effective containment measures? We asked various experts.

Variant of the English virus, Ricciardi: «London has been silent for 3 months. Faster contagion, blocking needed “
What are the dangers of the mutated virus?
“In a preliminary study, for the first time, increased infectivity of Sars Cov 2 is shown – underlines Roberto Luzzati, professor of infectious diseases at the University of Trieste – We already know that viruses replicate very quickly. In this case, it is the first time that a genetic mutation involves the variation of the peak protein. And that is why the alarm that caused the suspension of flights is justified ”. At the moment, explains Mauro Pistello, professor of Microbiology and Clinical Microbiology at the University of Pisa “there is no evidence that this mutation is more pathogenic or that it is not protected by current vaccines”. Furthermore, “it is not the first time that a mutation has been found that increases contagion,” recalls Roberto Cauda, director of Infectious Diseases at the Gemelli Polyclinic in Rome, who together with the group led by Massimo Ciccozzi from the Bio-medical Campus in June in evidence a mutation found later in the United States. “It made us believe that compared to central Wuhan it leads to higher transmissibility. Now we will have to understand more about this other variant. The virus has mutated and a higher transmission speed has been calculated ”.
Is it more dangerous to go to public places?
The new mutation of the virus is certainly even more dangerous if distances are not respected. Care must be taken to avoid meetings both outdoors and indoors, in bars, restaurants, public transport, warns Massimo Andreoni, director of the infectious disease clinic at the Tor Vergata Polyclinic in Rome. We must be even more on guard because, if for example this mutation were prevalent in asymptomatic people or in subjects who transmit the virus the most, Sars Cov 2 would have a greater chance of being transmitted in public places – Pistello specifies – Surely in this period of great crowding. the dangers are much greater.
How is it possible to defend yourself?
“At present, the measures to be adopted are the same as we are following, that is, distancing, masks and hand hygiene,” says Claudio Mastroianni, director of the infectious diseases clinic at the Umberto I Polyclinic in Rome. “Closing flights is a good measure because it makes less people circulate,” adds Sergio Abrignani, professor of immunology and general pathology at Milan State University. We must, however, remove the soil under the feet of this virus, which means Let’s say get vaccinated as soon as possible. But in the meantime, let’s act as if we were locked up. We avoid going out if it is not strictly necessary. “In case of traveling for work reasons, the experts repeat, if it is not possible to use the car, it is good to use transport Public only if there are not many people. It is good to leave home earlier than usual to be able to choose the less crowded bus. At the bar, remember to always wear a mask while speaking. When drinking coffee, it is advisable to stay away from other customers. « All viruses tend to change – explains Abrignani – but the more guests we give them, the more Sars Cov 2 will replicate and the more mutations it will produce. And in the end there will be a greater chance of generating the virus. wild card that for him is the variant that escapes the vaccine. Given the situation, this is not the time to worry about Christmas dinner.
