The Delta variant of Covid (former Indian variant) will soon become dominant also in Italy. Word of Giorgio Palù, virologist, member of the Scientific Technical Committee and president of the AIFA board of directors, who in a long interview with Corriere della Sera explained why this mutation, which is spreading rapidly to other countries, such as Kingdom United, Russia, Australia e United States, it could soon be responsible for most of the infections in Italy too. Where, however, its presence, according to the latest data released by the ISS, already appears to be quadrupled in one month, going from 4.2% in May to 16.8% in June. However, according to the expert, one should not be afraid although it is more contagious. “The evolutionary process of a pandemic virus consists in adapting more and more to the host species and not in becoming more virulent, on pain of its own extinction. We will soon understand if we are dealing with a strain that gives rise to less serious manifestations having as target the upper respiratory tract, nose and pharynx, “he added.
Palù also added that this variant seems to strike more children e teenagers: “This is due to the fact that although they have fewer receptors for the virus in the cells of the upper respiratory tract, nose and throat, they are more easily infected as the variant has acquired a higher affinity for the receptors themselves,” he explained. The disease due to the Delta variant, first identified in India a few months ago, also presents different symptoms compared to that caused by other viral strains, certainly milder. “We do not know if this described less aggression is linked to the fact that in England, where it is more studied because it is more widespread, many of the Delta virus positives had already received the first dose of vaccine, acquiring some protection. There vaccination it is a significant shield against severe forms and hospitalizations “, added Palù, according to whom” the vaccine protects with great effectiveness “and for this” we need to accelerate the immunization campaign in all age groups, from 12 years upwards , making the utmost effort to cover those approximately 2.5 million over 60 who have not yet been vaccinated, the most exposed “. white area, there is no pressure on hospitals and the incidence of contagion remains low. Added to this are also natural elements: “Sunstroke, open air, wind. The virus subjected to these natural fighting actions has a short life because it is hindered from spreading via aerosol “, concluded Palù.
