\nUn studiu britanic arat\u0103 c\u0103 num\u0103rul persoanelor care au anticorpi Covid-19 a sc\u0103zut semnificativ \u00een cursul verii, ceea ce sugereaz\u0103 c\u0103 vindecarea de coronavirus s-ar putea s\u0103 nu ofere imunitate pe termen lung, conform publica\u0163iei The Wall Street Journal.<\/p>\n
\nStudiul a fost efectuat de Colegiul Imperial Londra \u015fi de Institutul de sondaje Ipsos Mori, cu finan\u0163area Guvernului Marii Britanii, pe un e\u015fantion de 365.000 de adul\u0163i din Anglia. Conform rezultatelor, propor\u0163ia persoanelor care au anticorpi Covid-19 a sc\u0103zut cu 26,5% \u00een perioada 20 iunie-28 septembrie. V\u00e2rful infect\u0103rilor cu SARS-CoV-2 fusese atins cu 12 s\u0103pt\u0103m\u00e2ni \u00eenainte de 20 iunie.<\/p>\n
\nRezultatele sugereaz\u0103 \u015fi c\u0103 persoanele infectate care nu au avut simptome vizibile sunt predispuse la pierderea anticorpilor detectabili \u00eenaintea celor care au manifestat simptome. Rezultatele studiului nu au fost analizate \u00eenc\u0103 de al\u0163i exper\u0163i.<\/p>\n
\nMedicii nu \u015ftiu \u00eenc\u0103 dac\u0103 anticorpii confer\u0103 vreo imunitate \u00eempotriva reinfect\u0103rii cu noul coronavirus. Dar chiar dac\u0103 apare imunitate, acest studiu sugereaz\u0103, dac\u0103 rezultatele vor fi confirmate, c\u0103 perspectiva atingerii imunit\u0103\u0163ii comunitare va fi greu de atins.<\/p>\n
\nImunitatea comunitar\u0103 se produce atunci c\u00e2nd suficiente persoane dintr-o popula\u0163ie dezvolt\u0103 o reac\u0163ie imun\u0103, fie prin infectarea anterioar\u0103, fie prin vaccinare, astfel \u00eenc\u00e2t virusul s\u0103 nu se mai r\u0103sp\u00e2ndeasc\u0103 rapid, iar cei care nu sunt imuni s\u0103 fie proteja\u0163i.<\/p>\n
\nConform studiului, persoanele cu v\u00e2rste cuprinse \u00eentre 18 \u015fi 24 de ani pierd anticorpii \u00eentr-un ritm mai lent dec\u00e2t cei de peste 75 de ani. Cel mai mic declin al anticorpilor, de 14,9%, a fost \u00eenregistrat \u00een r\u00e2ndul persoanelor cu v\u00e2rste \u00eentre 18 \u015fi 24 de ani, iar cel mai accentuat, 29%, \u00een r\u00e2ndul celor peste 75 de ani.<\/p>\n","protected":false},"excerpt":{"rendered":"
