Bloodborne HIV: Don't Get Stuck!

[return to the first circumcision page]

National surveys in 27 countries report the percentages of intact and circ’d men who are HIV-positive. Intact men are LESS LIKELY to be HIV-positive in 15 of 27 countries (see Table below), and the median (middle) ratio of the percentages of HIV-infected intact vs circ’d men is 0.89 — intact men are 11% less likely to be HIV-positive.

In nine countries only very small numbers of surveyed men were intact, so the ratios are less reliable (see countries in bold and italics in the Table below). Considering only the 18 countries in which at least 5% of surveyed men are intact, intact men are less likely to be HIV-positive in six countries. In these 18 countries, ratios of HIV in intact vs. circ’d men range from 0.23 in Cameroon to 4.4 in Kenya, and the median (middle) ratio is 1.3 — intact men are 30% more likely to be HIV-positive (see Table).

Survey data are available for 13 of the 14 countries where the US and partners target men for circ’ing (see starred countries in the Table). In 3 of these 13 countries, intact men have less HIV than circ’d men, and the median (middle) ratio is 1.4.

The wide range of ratios of HIV prevalence in intact vs. circ’d men leaves us with a puzzle: why do intact men have less HIV in some communities, but more in others?
