	N	Prevalence
By Continuous Date Questions (n = 605)b
Point Prevalence at 6 months prior	66	10.9%
Minimum Cumulative Prevalence over past 12 months	167	27.6%
Maximum Cumulative Prevalence over past 12 months	173	28.6%
By Categorical Questions (n = 636)c
Point Prevalence at 6 months prior	67	10.5%
Minimum Cumulative Prevalence over past 12 months	108	17.0%
Maximum Cumulative Prevalence over past 12 months	188	29.6%

^aPoint prevalence is the number of women having more than one ongoing sexual partnership six months before the survey date, divided by the total number of sexually active women who provided dates of partnerships. Cumulative prevalence is the proportion of participants who had overlapping sexual partnerships during the 12 months prior to the survey date. A minimum cumulative prevalence was estimated using discrete partnership dates and a maximum cumulative prevalence was obtained by allowing the end of one sexual partnership and the beginning of the next partnership to occur on the same day or during the same time period.

^b45 women did not provide valid continuous date information within 12 months for any sexual partnerships.

^c14 women did not provide categorical date information within 12 months for any sexual partnership.
