Trends and predictors of HIV positivity and time since last test at voluntary counselling and testing encounters among adults in Kilifi, Kenya, 2006-2017. Wellcome Open Res 2021; 4:127.

Abstract
Background: Little is known about HIV retesting uptake among key populations (KP) and general populations (GP) in Kenya. We assessed trends and predictors of first-time testing (FTT), late retesting (previous test more than one year ago for GP or three months for KP), and test positivity at three voluntary counselling and testing (VCT) centres in coastal Kenya. Methods: Routine VCT data covering 2006-2017 was collected from three VCT centres in Kilifi County. We analysed HIV testing history and test results from encounters among adults 18-39 years, categorized as GP men, GP women, men who have sex with men (MSM), and female sex workers (FSW). Results: Based on 24,728 test encounters (32% FTT), we observed declines in HIV positivity (proportion of encounters where the result was positive) among GP men, GP women, first-time testers and MSM but not among FSW. The proportion of encounters for FTT and late retesting decreased for both GP and KP but remained much higher in KP than GP. HIV positivity was higher at FTT and late retesting encounters; at FSW and MSM encounters; and at encounters with clients reporting lower educational attainment and sexually transmitted infection (STI) symptoms. HIV positivity was lower in GP men, never married clients and those less than 35 years of age. FTT was associated with town, risk group, age 18-24 years, never-married status, low educational attainment, and STI symptoms. Late retesting was less common among encounters with GP individuals who were never married, had Muslim or no religious affiliation, had lower educational attainment, or reported STI symptoms. Conclusions: HIV positive test results were most common at encounters with first-time testers and late re-testers. While the proportion of encounters at which late retesting was reported decreased steadily over the period reviewed, efforts are needed to increase retesting among the most at-risk populations.

Abstract
Background: Little is known about HIV retesting uptake among key populations (KP) and general populations (GP) in Kenya. We assessed trends and predictors of new HIV diagnosis, first-time testing (FTT), and late retesting (previous test more than one year ago for GP or three months for KP). Methods: Data was collected routinely at three voluntary counselling and testing (VCT) centres in Kilifi County between 2006 and 2017. We analysed test encounters among adults 18-39 years, categorized as GP men, GP women, men who have sex with men (MSM), and female sex workers (FSW). Results: Based on 25,670 test encounters (32% FTT), we observed significant declines in HIV positivity (proportion of encounters with a new HIV diagnosis) among GP men, GP women, and first-time testers, but not among MSM and FSW. FTT and late retesting decreased for both GP and KP, but remained much higher in KP than GP. In 2017, less than 20% of KP were testing quarterly as recommended. HIV positivity was higher at FTT and late retesting encounters (relative to on-time retesting); at FSW and MSM encounters; and at encounters with clients reporting lower educational attainment, sexually transmitted infection (STI) symptoms, or no religious affiliation. HIV positivity was lower in GP men and younger clients. FTT was associated with town, risk group, age 18-24 years, never-married status, low educational attainment, and STI symptoms. Late retesting was less common among encounters with GP individuals who were never married, had Muslim or no religious affiliation, had lower educational attainment, or reported STI symptoms. Conclusions: New HIV diagnoses were most common among first-time testers and late re-testers. While late retesting decreased steadily over the period reviewed, achievement of the county's 90% HIV diagnosis target will require redoubled efforts to increase retesting among the most at risk populations.
