A hist\u00f3ria nos diz que esta cidade promissora mudou com as constru\u00e7\u00f5es ferrovi\u00e1rias e os trabalhadores do sexo - duas formas de transporte que o v\u00edrus HIV encontrou para se espalhar.<\/p>\n<p>Originalmente, existem dois tipos do v\u00edrus HIV: HIV-1 grupo M e HIV-1 grupo O. O HIV-1 grupo M foi o que se espalhou de Kinshasa para o mundo.
