Variante Delta: scoperti i primi 9 casi in Italia<\/strong><\/p>\n

\"\"<\/p>\n

In Italia, sono stati accertati<\/strong> gi\u00e0 i primi 9 casi di sottovariante Delta<\/strong>, notizia che anche con il vaccino, la situazione si sta facendo davvero molto dura.<\/p>\n

Attualmente in Italia, il numero di vaccinati sono il 71,4%<\/strong> ad aver ricevuto entrambi le dosi, e 85,7%<\/strong>, ad aver ricevuto almeno una delle due dosi.<\/p>\n

Il Covid, sembrava far meno paura, ma purtroppo, ora che questa variante \u00e8 arrivata, c’\u00e8 da rimettere tutto quanto in discussione.<\/strong><\/p>\n

La\u00a0nuova sottovariante Delta<\/strong>, denominata dagli scienziati AY.4.2 e indicata con la sigla B.1.617.2.4.2, \u00e8 arrivata anche nel nostro bel paese.<\/p>\n

Sottovariante Delta<\/h2>\n

Attualmente, sono stati\u00a0identificati 9 casi tra settembre e ottobre. Lo hanno svelato le sequenze genetiche contenute nella banca dati internazionale Gisaid<\/strong>, analizzate dagli esperti del Ceinge-Biotecnologie avanzate di Napoli.<\/strong><\/p>\n

In tutto sono state depositate 1.860 sequenze di questa variante.\u00a0La maggior parte arriva dalla Gran Bretagna <\/strong>e le altre da una decina di Paesi europei<\/strong>, tra cui l\u2019Italia. La variante Delta \u00e8 arrivata recentemente, e per i ricercatori \u00e8 ancora un incognita.<\/p>\n

Secondo gli esperti potrebbe essere pi\u00f9 contagiosa<\/strong>\u00a0fino al 10%. Il picco di casi \u00e8 stato rilevato in Gran Bretagna.<\/p>\n

La variante AY.4.2 si contraddistingue per via di due mutazioni\u00a0<\/strong>presenti nella proteina Spike, che il virus usa per aggredire le cellule.<\/p>\n

Una mutazione, conosciuta perch\u00e9 presente nella variante Delta si chiama A222V, l\u2019altra Y145H.<\/p>\n

L\u2019ipotesi, \u00e8 che alcuni ricercatori britannici, come Jeffrey Barrett<\/strong> del Welcome Sanger Institute di Cambridge e Francois Balloux dell\u2019University College di Londra,\u00a0questa variante sarebbe pi\u00f9 aggressiva<\/strong>\u00a0della Delta dal 10 al 15%.<\/p>\n

Massimo Zollo, fa sapere che i dati ancora non sono sufficienti per avere delle certezze:<\/strong><\/p>\n

\u201cQuello che invece \u00e8 chiaro fin da adesso \u00e8 che le possibili azioni per contrastare eventuali varianti in grado di sfuggire ai vaccini sono almeno due: la prima potrebbe portare a farmaci in grado di bloccare l\u2019ingresso del virus nelle cellule; la seconda punta a generare nuovi antivirali che blocchino la replicazione del virus nelle cellule<\/em>\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
