\n\u00cent\u00e2rzierea vaccin\u0103rii ar putea duce la apari\u0163ia altor variante de coronavirus. Oamenii de \u015ftiin\u0163\u0103 spun c\u0103 lumea a atins un punct precar \u00een pandemia Covid-19, \u00een care s-a creat un mediu propice pentru apari\u0163ia mai multor noi variante de coronavirus.<\/p>\n
\n\u201eDac\u0103 toat\u0103 lumea are imunitate, atunci virusul nu se poate adapta\u201d, a spus Emma Hodcroft, specialist epidemiologie molecular\u0103 a Universit\u0103\u0163ii din Berna.<\/p>\n
\nNoile variante ar putea reduce, de asemenea, eficacitatea vaccinurilor \u015fi tratamentelor Covid-19 \u015fi ar putea duce la reinfec\u0163ii \u00een r\u00e2ndul persoanelor care s-au recuperat deja dup\u0103 Covid-19, potrivit The Wall Street Journal.<\/p>\n
\nOamenii de \u015ftiin\u0163\u0103 spun c\u0103 solu\u0163ia minimiz\u0103rii acestor probleme const\u0103 \u00een distan\u0163area social\u0103 \u015fi alte m\u0103suri de reducere a contagiunii, precum \u015fi \u00een intensificarea eforturilor de vaccinare, care sunt \u00eencetinite.<\/p>\n
\nC\u00e2nd un virus infecteaz\u0103 pe cineva, acesta creeaz\u0103 multe variante ale sale. De fiecare dat\u0103 c\u00e2nd se \u00eent\u00e2mpl\u0103, erorile pot fi introduse \u00een codul s\u0103u genetic. Unele dintre aceste erori sau muta\u0163ii nu au niciun efect asupra comportamentului virusului. Altele, cum ar fi unele dintre cele v\u0103zute \u00een variantele \u00eengrijor\u0103toare ap\u0103rute \u00een Marea Britanie, Africa de Sud \u015fi Brazilia, pot spori capacitatea virusului de a rezista \u00een fa\u0163a ap\u0103r\u0103rii noastre imune.<\/p>\n
\nCercet\u0103rile efectuate de Dr. Lessells \u015fi colegii s\u0103i au ar\u0103tat c\u0103 varianta B.1.351 s-a r\u0103sp\u00e2ndit ini\u0163ial cel mai rapid \u00een provincia sud-african\u0103 Eastern Cape, unde mul\u0163i reziden\u0163i au contractat deja virusul \u015fi s-au recuperat. El \u015fi colegii s\u0103i au ar\u0103tat, de asemenea, \u00eentr-o serie de experimente de laborator c\u0103 anticorpii de la indivizii infecta\u0163i anterior au fost mai pu\u0163in eficien\u0163i \u00eempotriva B.1.351 dec\u00e2t variantele anterioare ale coronavirusului.<\/p>\n
\nUnii cercet\u0103tori spun c\u0103 num\u0103rul mare de muta\u0163ii observate \u00een varianta B.1.351, mai multe de 20, sugereaz\u0103 c\u0103 muta\u0163iile au ap\u0103rut la un singur pacient \u00eenainte de a se r\u0103sp\u00e2ndi la al\u0163ii.<\/p>\n
\nLa nivel mondial, SARS-CoV-2 a infectat peste 110 milioane de oameni \u015fi a ucis peste 2,4 milioane.<\/p>\n","protected":false},"excerpt":{"rendered":"
