a Rate represents infection with HIV-1 only and dual infection

(HIV-1 and HIV-2), therefore, addition of rates from tables 1 and 2 is not advised.

b Data are best available but are not necessarily reliable due to small (<100) or unknown sample size.

c Data combined.

d Rate represents infection with HIV1 and/or HIV2.

Notes:

Multi entries for a given country represent different geographic areas or risk group. (See table 3 for details.)
