Table 3 The prevalence of sexually transmitted infections (STIs) among women aged 15–49 in Swaziland (n = 655)

STIs	Positive (n)	Crude Prevalence (%)	Survey weighted prevalence % (95% CI)	Population burden^a	95% CI
Overall	114	17.4	19.4 (14.9–24.8)	72990	51111–94871
TV	51	4.7	8.4 (5.4–12.8)	30132	16633–43631

HIV	276	42.1	42.7 (35.7–46.2)	153276	127336–179216
Hr-HPV (n = 644)	273	42.1	46.2 (42.8–49.5)	174046	153294–194797
Multiple STIs^b	20	3.1	4.0 (2.3–6.0)	13995	7092–20898
^cTriple STIs (n = 644)^d	38	5.9	6.3 (4.4–8.9)	23310	14193–32427

^aPopulation burden estimates extrapolated (using sample statistics) based on the 2007–2030 population projections aligned to the 2014 population estimates
^bMultiple STIs – having two or more of the screened 5 STIs
^cTriple infection: at least one other STI including HIV and hr-HPV infection
^dA total of 11 women had insufficient specimen for hr-HPV testing therefore for the analysis for Triple STIs done on N = 644
