Omicron nereden geldi?<\/strong><\/p>\n\n\n\n

\u0130lk Omicron vakas\u0131 G\u00fcney Afrika’da tespit edildi. Omicron, Delta varyant\u0131ndan ba\u011f\u0131ms\u0131z olarak 2020’nin ortalar\u0131nda ortaya \u00e7\u0131kan ba\u015fka bir t\u00fcrden evrimle\u015fmi\u015f gibi g\u00f6r\u00fcn\u00fcyor.
