Virus lidsk\u00e9 imunodeficience (HIV), virus zp\u016fsobuj\u00edc\u00ed AIDS, se vyv\u00edj\u00ed zp\u016fsobem, kter\u00fd m\u016f\u017ee b\u00fdt pro lidstvo p\u0159\u00ednosn\u00fd.

Pomalej\u0161\u00ed replikace<\/h2>\n\n

V\u00fdzkumn\u00edci tak\u00e9 zjistili, \u017ee se HIV v Botswan\u011b replikuje pomaleji ne\u017e v Ji\u017en\u00ed Africe.
