\nVarianta Omicron a virusului care provoac\u0103 COVID-19 a dob\u00e2ndit probabil cel pu\u0163in una dintre muta\u0163iile sale prin preluarea unui fragment de material genetic de la un alt virus – posibil unul care provoac\u0103 r\u0103ceala comun\u0103, potrivit celui mai recent studiu.<\/p>\n
\nAceast\u0103 secven\u0163\u0103 genetic\u0103 nu apare \u00een nicio versiune anterioar\u0103 a coronavirusului, numit SARS-CoV-2, dar este omniprezent\u0103 \u00een multe alte virusuri, inclusiv \u00een cele care provoac\u0103 r\u0103ceala comun\u0103, precum \u015fi \u00een genomul uman, au precizat cercet\u0103torii.<\/p>\n
\nPrin preluarea acestui fragment special, Omicron ar putea s\u0103 par\u0103 “mai uman”, ceea ce l-ar ajuta s\u0103 se sustrag\u0103 de la atacul sistemului imunitar, a declarat Venky Soundarararajan, de la compania de studiere a datelor nference, care a condus studiul.<\/p>\n
\nAcest lucru ar putea \u00eensemna c\u0103 virusul se transmite mai u\u015for, dar provoac\u0103 forme mai u\u015foare de boal\u0103 sau simptomatice. Acest\u0103 presupunere va primii un r\u0103spuns cel mai probabil \u00een c\u00e2teva s\u0103pt\u0103m\u00e2ni c\u00e2nd analizele complete ale noii tulpini vor fi gata, relateaz\u0103 Reuters.<\/p>\n
\nCelulele din pl\u0103m\u00e2ni \u015fi din sistemul gastro-intestinal pot g\u0103zdui simultan coronavirusul SARS-CoV-2 \u015fi r\u0103ceal\u0103 comun\u0103, potrivit unor studii anterioare. O astfel de coinfec\u0163ie preg\u0103te\u015fte terenul pentru “recombinare viral\u0103”, un proces \u00een care dou\u0103 virusuri diferite din aceea\u015fi celul\u0103 gazd\u0103 interac\u0163ioneaz\u0103 \u00een timp ce se \u00eenmultuesc, gener\u00e2nd un virus ce are materialul genetic de la ambii “p\u0103rin\u0163i”.<\/p>\n
\nAceast\u0103 nou\u0103 muta\u0163ie ar fi putut s\u0103 apar\u0103 pentru prima dat\u0103 la o persoan\u0103 infectat\u0103 cu ambii agen\u0163i patogeni, atunci c\u00e2nd o versiune a SARS-CoV-2 a preluat secven\u0163a genetic\u0103 de la cel\u0103lalt virus, potrivit studiului.<\/p>\n
\nAceea\u015fi secven\u0163\u0103 genetic\u0103 apare de mai multe ori \u00eentr-unul dintre virusurile care provoac\u0103 r\u0103celi la oameni – cunoscut sub numele de HCoV-229E – \u015fi \u00een virusul imunodeficien\u0163ei umane (HIV) care provoac\u0103 SIDA, a spus Soundararajan.<\/p>\n
\nAfrica de Sud, unde Omicron a fost identificat pentru prima dat\u0103, are cea mai mare rat\u0103 de infectare cu HIV din lume, care sl\u0103be\u015fte sistemul imunitar \u015fi cre\u015fte vulnerabilitatea unei persoane la infec\u0163iile cu virusuri \u015fi al\u0163i agen\u0163i patogeni.<\/p>\n
\nNoile descoperiri subliniaz\u0103 c\u00e2t de important este ca oamenii s\u0103 se vaccineze.<\/p>\n
\n“Trebuie s\u0103 v\u0103 vaccina\u0163i pentru a reduce \u015fansele ca alte persoane, care sunt imunocompromise, s\u0103 \u00eent\u00e2lneasc\u0103 virusul SARS-CoV-2”, a spus Soundararajan.<\/p>\n","protected":false},"excerpt":{"rendered":"
