L'histoire nous apprend que cette ville prometteuse a chang\u00e9 avec les constructions de chemins de fer et les travailleurs du sexe - deux moyens de transport que le virus VIH a trouv\u00e9 pour se propager.<\/p>\n<p>A l'origine, il existe deux types de virus VIH : Le VIH-1 de groupe M et le VIH-1 de groupe O. Le VIH-1 de groupe M est celui qui s'est r\u00e9pandu dans le monde \u00e0 partir de Kinshasa. Le VIH-1 de groupe O, quant \u00e0 lui, est n\u00e9 \u00e0 proximit\u00e9 mais ne s'est jamais propag\u00e9, restant en Afrique de l'Ouest jusqu'\u00e0 aujourd'hui.<\/p>\n<p><a href=\"https:\/\/mindthegraph.com\/\"><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter wp-image-5937 size-full\" src=\"https:\/\/blog.mindthegraph.com\/wp-content\/uploads\/2016\/06\/output_vx7nah.gif\" alt=\"virus du VIH\" width=\"945\" height=\"708\" \/><\/a><\/p>\n<p>M.
