9.6 HIV PREVALENCE BY BACKGROUND CHARACTERISTICS
Findings are presented in Table 9.3 by background characteristics of respondents. While confidence
in the estimates is high, nevertheless differentials across sub-groups of the population cannot be
established.

Note: Figures in parentheses are based on 25-49 unweighted cases. An asterisk indicates that a figure is
based on fewer than 25 unweighted cases and has been suppressed.
Among women age 15-49, HIV-positive cases were found only among women age 25 to 34. A
larger sample size would likely have found a few HIV-positive cases among women of other ages as well.
The VPAIS found infection occurring among men age 20 to 39, a broader age range than was found
among women. However, as with women, a larger sample size would likely have found a few HIVpositive
cases among other age groups as well.
This is the first time in Vietnam that testing of HIV has incorporated the ability to know the
prevalence of both partners among cohabiting couples. The VPAIS identified 443 couples for which HIV
test results are available for both partners. In 99.3 percent of couples, both partners were HIV negative.
Among 0.4 percent of couples, both partners were HIV positive, and 0.2 percent were discordant, that is,
one partner was HIV positive and the other was not.
Although survey estimates do not allow drawing conclusions with regard to differentials in HIV
prevalence, the VPAIS does provide, for the first time, a robust estimate of HIV prevalence among the
general population of both sexes of reproductive age in Hai Phong province.
