Molecular epidemiology of HIV-1 non-M variants. Shown is a representation of the worldwide distribution of HIV-1 non-M variants according to the number of reported cases published. Three maps are presented for the HIV-O, HIV-N, and HIV-P variants. Only Europe and Africa are represented for the distribution of the variants N and P, as no infection was reported outside these regions. ∗, Togo is the most likely place of contamination of the HIV-N case reported by Delaugerre et al. (28), but no case was reported from this country.
