\nStudiul, care a analizat infec\u0163iile cu coronavirus \u00een peste 8.500 de gospod\u0103rii daneze \u00eentre decembrie \u015fi ianuarie, a constatat c\u0103 persoanele infectate cu subvarianta BA.2 au avut cu aproximativ 33% mai multe \u015fanse de a infecta alte persoane, \u00een compara\u0163ie cu cele infectate cu BA.1.<\/p>\n
\nLa nivel mondial, subvarianta “original\u0103” BA.1 reprezint\u0103 peste 98% din cazurile de Omicron, dar BA.2 a devenit rapid tulpina dominant\u0103 \u00een Danemarca, detron\u00e2nd BA.1 \u00een a doua s\u0103pt\u0103m\u00e2n\u0103 din ianuarie.<\/p>\n
\n“Am ajuns la concluzia c\u0103 Omicron BA.2 este \u00een mod inerent substan\u0163ial mai transmisibil\u0103 dec\u00e2t BA.1 \u015fi c\u0103 aceasta posed\u0103, de asemenea, propriet\u0103\u0163i imuno-evazive care reduc \u015fi mai mult efectul protector al vaccin\u0103rii \u00eempotriva infec\u0163iei”, au declarat cercet\u0103torii.<\/p>\n
\nStudiul, care nu a fost \u00eenc\u0103 revizuit de de al\u0163i cercet\u0103tori, a fost realizat de cercet\u0103tori de la Statens Serum Institut (SSI), Universitatea din Copenhaga, Statistics Denmark \u015fi Universitatea Tehnic\u0103 din Danemarca.<\/p>\n
\n“Dac\u0103 a\u0163i fost expus la Omicron BA.2 \u00een gospod\u0103ria dumneavoastr\u0103, ave\u0163i 39% probabilitate de a fi infectat \u00een termen de \u015fapte zile. Dac\u0103, \u00een schimb, a\u0163i fi fost expus la BA.1, probabilitatea este de 29%”, a declarat pentru Reuters autorul principal al studiului, Frederik Plesner.<\/p>\n
\nAcest lucru sugereaz\u0103 c\u0103 BA.2 este cu aproximativ 33% mai infec\u0163ios dec\u00e2t BA.1, a ad\u0103ugat el.<\/p>\n
\nCazuri de BA.2 au fost \u00eenregistrate \u015fi \u00een Statele Unite, Marea Britanie, Suedia \u015fi Norvegia, dar \u00eentr-o m\u0103sur\u0103 mult mai mic\u0103 dec\u00e2t \u00een Danemarca, unde reprezint\u0103 aproximativ 82% din cazuri.<\/p>\n
\nDe asemenea, studiul a ar\u0103tat c\u0103 BA.2 prezint\u0103 “propriet\u0103\u0163i mai mari de evitare a imunit\u0103\u0163ii” ale subvariantei.<\/p>\n
\nDar vaccinurile au jucat \u00een continuare un rol important, a subliniat studiul, deoarece at\u00e2t persoanele vaccinate cu rapel, c\u00e2t \u015fi cele complet vaccinate au avut mai pu\u0163ine \u015fanse de a se infecta \u015fi de a transmite oricare dintre cele dou\u0103 subvariante, \u00een compara\u0163ie cu cele nevaccinate.<\/p>\n
\nAnaliza preliminar\u0103 efectuat\u0103 de SSI a ar\u0103tat c\u0103 nu exist\u0103 nicio diferen\u0163\u0103 \u00een ceea ce prive\u015fte riscul de spitalizare pentru BA.2 \u00een compara\u0163ie cu BA.1.<\/p>\n
\nStudiul confirm\u0103, de asemenea, analiza preliminar\u0103 din Anglia, care a ar\u0103tat c\u0103 BA.2 pare s\u0103 aib\u0103 un avantaj substan\u0163ial de cre\u015ftere fa\u0163\u0103 de tipul BA.1, potrivit Agen\u0163iei britanice de securitate sanitar\u0103.<\/p>\n","protected":false},"excerpt":{"rendered":"
