\nSubvarianta BA.2 a Omicron, extrem de contagioas\u0103, a devenit dominant\u0103 la nivel mondial, provoc\u00e2nd valuri \u00een multe \u0163\u0103ri din Europa \u015fi Asia \u015fi st\u00e2rnind \u00eengrijorare \u00een Statele Unite.<\/p>\n
\nBA.2 reprezint\u0103 acum aproape 86% din toate cazurile, potrivit Organiza\u0163iei Mondiale a S\u0103n\u0103t\u0103\u0163ii. Este mai contagioas\u0103 dec\u00e2t celelalte subvariante ale Omicron, BA.1 \u015fi BA.1.1, \u00eens\u0103 dovezile de p\u00e2n\u0103 acum sugereaz\u0103 c\u0103 nu ar provoca boli grave, scrie Reuters.<\/p>\n
\nCa \u015fi \u00een cazul celorlalte variante Omicron, vaccinurile sunt mai pu\u0163in eficiente \u00eempotriva BA.2 dec\u00e2t \u00eempotriva variantelor anterioare, cum ar fi Alpha sau tulpina original\u0103 de coronavirus, iar protec\u0163ia scade \u00een timp.<\/p>\n
\nCu toate acestea, conform datelor Agen\u0163iei de Securitate Sanitar\u0103 din Marea Britanie, protec\u0163ia este restabilit\u0103 de o doz\u0103 booster, \u00een special pentru prevenirea spitaliz\u0103rii \u015fi a decesului.<\/p>\n
\nR\u0103sp\u00e2ndirea BA.2 a fost pus\u0103 pe seama recentelor cre\u015fteri ale cazurilor \u00een China, precum \u015fi a infec\u0163iilor record din \u0163\u0103ri europene precum Germania \u015fi Regatul Unit. Cu toate acestea, unele \u0163\u0103ri europene \u00eenregistreaz\u0103 acum o cre\u015ftere mai lent\u0103 a num\u0103rului de cazuri noi sau chiar un declin.<\/p>\n
\nBA.2 a fost numit\u0103 \u201evarianta invizibil\u0103”, deoarece este mai greu de urm\u0103rit.<\/p>\n
\nO preocupare cheie cu privire la aceast\u0103 subvariant\u0103 este reinfectarea persoanelor care au avut deja BA.1, \u00een special pentru c\u0103 o serie de \u0163\u0103ri p\u0103reau s\u0103 se confrunte cu \u201ev\u00e2rfuri duble” ale ratelor de infectare surprinz\u0103tor de apropiate. \u00cens\u0103 datele din Marea Britanie \u015fi Danemarca au ar\u0103tat c\u0103, \u00een timp ce Omicron poate reinfecta persoanele care au avut alte variante, cum ar fi Delta, p\u00e2n\u0103 acum au fost descoperite doar c\u00e2teva cazuri de reinfectare cu BA.2 la persoane care au avut BA.1.<\/p>\n
\nOamenii de \u015ftiin\u0163\u0103 spun c\u0103 o posibil\u0103 explica\u0163ie pentru r\u0103sp\u00e2ndirea recent\u0103 a num\u0103rului de cazuri de BA.2 ar putea consta \u00een ridicarea simultan\u0103 a restric\u0163iilor \u00een mai multe \u0163\u0103ri.<\/p>\n
\n\u201eBA.2 a fost varianta care a circulat c\u00e2nd to\u0163i ace\u015fti oameni au \u00eencetat s\u0103 mai poarte m\u0103\u015fti”, a declarat Dr. Andrew Pekosz, virusolog la Johns Hopkins Bloomberg School of Public Health din Baltimore.<\/p>\n
\nIndiferent de cauza r\u0103sp\u00e2ndirii repide a BA.2, oamenii de \u015ftiin\u0163\u0103 sunt de p\u0103rere c\u0103 este un memento pentru faptul c\u0103 virusul continu\u0103 s\u0103 provoace daune, \u00een special \u00een r\u00e2ndul celor nevaccina\u0163i, subvaccina\u0163i \u015fi vulnerabili.<\/p>\n
