Abstract Background Home-based HIV testing and counselling (HB-HTC) is frequently used to increase awareness of HIV status in sub-Saharan Africa. Whereas acceptance of HB-HTC is usually high, testing coverage may remain low due to household members being absent during the home visits. This study assessed whether two consecutive visits, one during the week, one on the weekend, increase coverage. Methods The study was a predefined nested-study of the CASCADE-trial protocol and conducted in 62 randomly selected villages and 17 urban areas in Butha-Buthe district, Lesotho. HB-HTC teams visited each village/urban area twice: first during a weekday, followed by a weekend visit to catch-up for household members absent during the week. Primary outcome was HTC coverage after first and second visit. Coverage was defined as all individuals who knew their HIV status out of all household members (present and absent). Results HB-HTC teams visited 6665 households with 18,286 household members. At first visit, 69.2 and 75.4% of household members were encountered in rural and urban households respectively (p < 0.001) and acceptance for testing was 88.5% in rural and 79.5% in urban areas (p < 0.001), resulting in a coverage of 61.8 and 61.5%, respectively. After catch-up visit, the HTC coverage increased to 71.9% in rural and 69.4% in urban areas. The number of first time testers was higher at the second visit (47% versus 35%, p < 0.001). Direct cost per person tested and per person tested HIV positive were lower during weekdays (10.50 and 335 USD) than during weekends (20 and 1056 USD). Conclusions A catch-up visit on weekends increased the proportion of persons knowing their HIV status from 62 to 71% and reached more first-time testers. However, cost per person tested during catch-up visits was nearly twice the cost during first visit. Trial registration NCT02692027 (prospectively registered on February 21, 2016).

AbstractBackgroundKnowledge of HIV status (KOS) among people living with HIV (PLHIV) is essential for an effective national HIV response. This study estimates progress and gaps in reaching the UNAIDS 2020 target of 90% KOS, and the efficiency of HIV testing services (HTS) in sub-Saharan Africa (SSA), where two thirds of all PLHIV live.MethodsWe used data from 183 population-based surveys (N=2.7 million participants) and national HTS programs (N=315 country-years) from 40 countries as inputs into a mathematical model to examine trends in KOS among PLHIV, median time from HIV infection to diagnosis, HIV testing positivity, and proportion of new diagnoses among all positive tests, adjusting for retesting.FindingsAcross SSA, KOS steadily increased from 6% (95% credible interval [95%CrI]: 5% to 7%) in 2000 to 84% (95%CrI: 82% to 86%) in 2020. Twelve countries and one region, Southern Africa, reached the 90% target. In 2020, KOS was lower among men (79%) than women (87%) across SSA. PLHIV aged 15-24 years were the least likely to know their status (65%), but the largest gap in terms of absolute numbers was among men aged 35-49 years, with over 700,000 left undiagnosed. As KOS increased from 2000 to 2020, the median time to diagnosis decreased from 10 to 3 years, HIV testing positivity declined from 9% to 3%, and the proportion of first-time diagnoses among all positive tests dropped from 89% to 42%.InterpretationOn the path towards the next UNAIDS target of 95% diagnostic coverage by 2030, and in a context of declining positivity and yield of first-time diagnoses, we need to focus on addressing disparities in KOS. Increasing KOS and treatment coverage among older men could be critical to reduce HIV incidence among women in SSA, and by extension, reducing mother-to-child transmission.

Abstract BACKGROUND HIV testing coverage remains below the targeted 90% despite efforts and resources invested. Home-based HIV testing is a key approach endorsed by the World Health Organization (WHO), especially to reach individuals who might not seek testing otherwise. Although acceptance of test-ing during such campaigns is high, coverage remains low due to absent household members. This cluster-randomized trial aims to assess increase in testing coverage using oral HIV self-testing (HIVST) among individuals who are absent or decline testing during home-based HIV testing. METHODS The HOSENG (HOme-based SElf-testiNG) trial is a cluster-randomized, parallel group, superiority trial in two districts of Lesotho, Southern Africa. Clusters are stratified by district, village size, and village access to the nearest health facility. Cluster eligibility criteria include: village is in catchment area of one of the study facilities, village authority provides consent, and village has a registered, capable and consenting village health worker (VHW). In intervention clusters, HIV self-tests are provided for eligible household members who are absent or decline HIV testing in presence of the campaign team. In control clusters, standard of care for absent and refusing individuals applies, i.e. referral to health facility. The primary outcome is HIV testing coverage among individuals 12 years and older within 120 days after enrolment. Secondary objectives include HIV testing coverage among other age groups, and uptake of the different testing modalities. Statistical analyses will be conducted and reported in line with CONSORT guidelines. HOSENG trial is linked to VIBRA (Village-Based Refill of ART) trial. Together, they constitute the GET ON (GETting tOwards Ninety) research project. DISCUSSION The HOSENG trial tests if oral HIVST may be an add-on during door-to-door testing campaigns towards achieving optimal testing coverage. The provision of oral self-test kits, followed up by VHWs, requires little additional human resources, finances and logistics. If cost-effective, this approach will inform home-based HIV testing policies not only in Lesotho, but in similar high-prevalence settings. TRIAL REGISTRATION This trial has been registered at clinicaltrials.gov (NCT03598686) on July 25, 2018. More information under www.getonproject.wordpress.com.

Recurrent skin and soft tissue infections (SSTI) caused by Community-Associated Methicillin-Resistant Staphylococcus aureus (CA-MRSA) or Methicillin-Sensitive Staphylococcus aureus (CA-MSSA) present treatment challenges. This community-based trial examined the effectiveness of an evidence-based intervention (CDC Guidelines, topical decolonization, surface decontamination) to reduce SSTI recurrence, mitigate household contamination/transmission, and improve patient-reported outcomes. Participants (n = 186) were individuals with confirmed MRSA(+)/MSSA(+) SSTIs and their household members. During home visits; Community Health Workers/Promotoras provided hygiene instructions; a five-day supply of nasal mupirocin; chlorhexidine for body cleansing; and household disinfecting wipes (Experimental; EXP) or Usual Care Control (UC CON) pamphlets. Primary outcome was six-month SSTI recurrence from electronic health records (EHR). Home visits (months 0; 3) and telephone assessments (months 0; 1; 6) collected self-report data. Index patients and participating household members provided surveillance culture swabs. Secondary outcomes included household surface contamination; household member colonization and transmission; quality of life; and satisfaction with care. There were no significant differences in SSTI recurrence between EXP and UC in the intent-to-treat cohort (n = 186) or the enrolled cohort (n = 119). EXP participants showed reduced but non-significant colonization rates. EXP and UC did not differ in household member transmission, contaminated surfaces, or patient-reported outcomes. This intervention did not reduce clinician-reported MRSA/MSSA SSTI recurrence. Taken together with other recent studies that employed more intensive decolonization protocols, it is possible that a promotora-delivered intervention instructing treatment for a longer or repetitive duration may be effective and should be examined by future studies.

Background Direct measures of HIV incidence are needed to assess the population-level impact of prevention programs but are scarcely available in the subnational epidemic hotspots of sub-Saharan Africa. We created a sentinel HIV incidence cohort within a community-based program that provided home-based HIV testing to all residents of Namibia’s Zambezi region, where approximately 24% of the adult population was estimated to be living with HIV. Objective The aim of this study was to estimate HIV incidence, detect correlates of HIV acquisition, and assess the feasibility of the sentinel, community-based approach to HIV incidence surveillance in a subnational epidemic hotspot. Methods Following the program’s initial home-based testing (December 2014-July 2015), we purposefully selected 10 clusters of 60 to 70 households each and invited residents who were HIV negative and aged ≥15 years to participate in the cohort. Consenting participants completed behavioral interviews and a second HIV test approximately 1 year later (March-September 2016). We used Poisson models to calculate HIV incidence rates between baseline and follow-up and multivariable Cox proportional hazard models to assess the correlates of seroconversion. Results Among 1742 HIV-negative participants, 1624 (93.23%) completed follow-up. We observed 26 seroconversions in 1954 person-years (PY) of follow-up, equating to an overall incidence rate of 1.33 per 100 PY (95% CI 0.91-1.95). Among women, the incidence was 1.55 per 100 PY (95% CI 1.12-2.17) and significantly higher among those aged 15 to 24 years and residing in rural areas (adjusted hazard ratio [aHR] 4.26, 95% CI 1.39-13.13; P=.01), residing in the Ngweze suburb of Katima Mulilo city (aHR 2.34, 95% CI 1.25-4.40; P=.01), who had no prior HIV testing in the year before cohort enrollment (aHR 3.38, 95% CI 1.04-10.95; P=.05), and who had engaged in transactional sex (aHR 17.64, 95% CI 2.88-108.14; P=.02). Among men, HIV incidence was 1.05 per 100 PY (95% CI 0.54-2.31) and significantly higher among those aged 40 to 44 years (aHR 13.04, 95% CI 5.98-28.41; P<.001) and had sought HIV testing outside the study between baseline and follow-up (aHR 8.28, 95% CI 1.39-49.38; P=.02). No seroconversions occurred among persons with HIV-positive partners on antiretroviral treatment. Conclusions Nearly three decades into Namibia’s generalized HIV epidemic, these are the first estimates of HIV incidence for its highest prevalence region. By creating a sentinel incidence cohort from the infrastructure of an existing community-based testing program, we were able to characterize current transmission patterns, corroborate known risk factors for HIV acquisition, and provide insight into the efficacy of prevention interventions in a subnational epidemic hotspot. This study demonstrates an efficient and scalable framework for longitudinal HIV incidence surveillance that can be implemented in diverse sentinel sites and populations.

Abstract Background Tanzania has met only 50.1% of the 90% target for diagnosing HIV in children. Context-specific strategies are necessary to find the hidden children for HIV testing. This study assesses the association between caregiver sex and HIV status of orphans and vulnerable children (OVC). Methods Data originate from the community-based, USAID-funded Kizazi Kipya Project, which works towards increasing OVC’s and their caregivers’ uptake of HIV/AIDS and other social services in Tanzania. Included in this study are 39,578 OVC ages 0–19 years who the project served during January-March 2017 in 18 regions of Tanzania and who voluntarily reported their HIV status. Data analysis involved multi-level logistic regression, with OVC HIV status as the outcome and caregiver’s sex the main independent variable. Results Three-quarters (74.3%) of the OVC included in the study had female caregivers, and their overall HIV prevalence was 7.1%. The prevalence was significantly higher (p<0.001) among OVC with male caregivers (7.8%) than among OVC with female caregivers (6.8%), and indeed, multivariate analysis showed that OVC with male caregivers were significantly 40% more likely to be HIV-positive than those with female caregivers (OR=1.40, 95% CI 1.08–1.83). This effect was the strongest among 0–4 year-olds (OR=4.02, 95% CI 1.61–10.03), declined to 1.72 among 5–9 year-olds (OR=1.72, 95% CI 1.02–2.93), and lost significance for children over age 9 years. This effect was adjusted for OVC sex and nutritional status; caregiver marital status, education level, and HIV status; family’s place of residence, size, wealth quintile, and health insurance ownership; and co-residence of multiple OVC. Conclusion OVC in Tanzania with male caregivers have a 40% higher likelihood of being HIVpositive than those with female caregivers. HIV risk assessment activities should target OVC with male caregivers, as well as OVC who have malnutrition, HIV-positive caregivers, or caregivers who do not disclose their HIV status to community volunteers. Further, younger HIV-positive OVC are more likely to live in rural areas, while older HIV-positive OVC are more likely to live in urban areas. These factors should be integrated in HIV risk assessment algorithms to enhance HIV testing yields and pediatric case-finding in the OVC population in Tanzania.

Background HIV prevalence in Mozambique (12.6%) is one of the highest in the world, yet ~40% of people living with HIV (PLHIV) do not know their HIV status. Strategies to increase HIV testing uptake and diagnosis among PLHIV are urgently needed. Home-based HIV testing services (HBHTS) have been evaluated primarily as a 1-time campaign strategy. Little is known about the potential of repeating HBHTS to diagnose HIV infection among persons who have never been tested (NTs), nor about factors/reasons associated with never testing in a generalized epidemic setting. Methods During 2014–2017, counselors visited all households annually in the Chókwè Health and Demographic Surveillance System (CHDSS) and offered HBHTS. Cross-sectional surveys were administered to randomly selected 10% or 20% samples of CHDSS households with participants aged 15–59 years before HBHTS were conducted during the visit. Descriptive statistics and logistic regression were used to assess the proportion of NTs, factors/reasons associated with never having been tested, HBHTS acceptance, and HIV-positive diagnosis among NTs. Results The proportion of NTs decreased from 25% (95% confidence interval [CI]:23%–26%) during 2014 to 12% (95% CI:11% –13%), 7% (95% CI:6%–8%), and 7% (95% CI:6%–8%) during 2015, 2016, and 2017, respectively. Adolescent boys and girls and adult men were more likely than adult women to be NTs. In each of the four years, the majority of NTs (87%–90%) accepted HBHTS. HIV-positive yield among NTs subsequently accepting HBHTS was highest (13%, 95% CI:10%–15%) during 2014 and gradually reduced to 11% (95% CI:8%–15%), 9% (95% CI:6%–12%), and 2% (95% CI:0%–4%) during 2015, 2016, and 2017, respectively. Conclusions Repeated HBHTS was helpful in increasing HIV testing coverage and identifying PLHIV in Chókwè. In high HIV-prevalence settings with low testing coverage, repeated HBHTS can be considered to increase HIV testing uptake and diagnosis among NTs.

Abstract Background Globally only 79% of adults living with HIV (human immunodeficiency virus) know their status and men in sub-Saharan Africa are considered a particularly hard-to-reach population for HIV testing. Home-based HIV couple testing during the antenatal period is a safe and effective method that has been used to test male partners of pregnant women. The goal of this qualitative study was to identify elements that made couple testing successful and describe important characteristics of this home-based intervention from couples’ perspectives. Methods Couples who received scheduled home-based couple testing during pregnancy in Kisumu, Kenya, were purposively sampled based on HIV status from January to May 2015. An interviewer administered all of the in-depth interviews and two coders were directly involved in the data analysis and reconciled codes several times in the process. Results Twenty-one couples were enrolled: 9 concordant HIV-negative couples, 8 HIV discordant couples, 3 HIV concordant HIV-positive couples, and 1 whose concordance status was unknown. Median age at the time of home-based couple testing was 24 and 28 years for women and men, respectively. Median relationship duration was 3 years and couples had a median of two pregnancies. The major themes that emerged were that home-based couple testing 1) removed the female burden of requesting couple testing, 2) overcame logistical barriers associated with clinic-based testing, 3) encouraged participants to overcome their fear of testing and disclosure, 4) provided privacy in the home, and 5) provided quality time with the health advisors. Importantly, some women appreciated individual testing at the clinic before couple testing and some couples preferred skilled, anonymous health advisors delivering the intervention rather than known community health workers. Conclusions The results of this qualitative study suggest that home-based couple testing during pregnancy overcame many of the barriers that limit men’s access to and uptake of clinic-based testing. It encouraged participants to overcome their fear of testing and disclosure through a setting that afforded privacy and quality time with skilled health advisors. These qualitative results may help design effective partner and couple HIV testing programs in the antenatal setting and alongside or within other assisted partner notification services.

BACKGROUNDRecurrent skin and soft tissue infections (SSTI) caused by Community-Associated Methicillin-Resistant (CA-MRSA) or Methicillin-Sensitive Staphylococcus aureus (CA-MSSA) present treatment challenges.OBJECTIVESCan an evidence-based intervention (CDC Guidelines, topical decolonization, surface decontamination) reduce SSTI recurrence, mitigate household contamination and transmission, and improve patient-reported outcomes?DESIGNRandomized trialSETTINGCommunity settingsPARTICIPANTSParticipants (n=186) with confirmed MRSA(+)/MSSA(+) SSTIs and household members.INTERVENTIONCommunity Health Workers/Promotoras conducted home visits and provided participants with instructions, a five-day supply of mupirocin for nasal application, chlorhexidine for body cleansing, and disinfecting wipes for household cleaning (EXP) versus Usual Care (UC).MEASUREMENTSPrimary outcome was six-month SSTI recurrence recorded in electronic health records (EHR). Home visits (months 0/3) and telephone assessments (months 0/1/6) collected self-report data. Surveillance culture swabs (nares, axilla, groin) were obtained from index patients and participating household members. Secondary outcomes included household surface contamination, household member colonization and transmission, quality of life and satisfaction with care.RESULTSAmong patients with SSTIs (n=421), 44.2% were MRSA(+)/MSSA(+); an intent-to-treat analyses (n=186) demonstrated no significant differences in SSTI recurrence (OR: 1.4, 95% CI: 0.51-3.5). Among the enrolled cohort (n=119), there were no significant SSTI recurrence effects (OR=1.14, 95% CI=0.35-3.6). EXP participants showed reduced but non-significant colonization rates. There were no differential reductions in household member transmission or in reductions in proportions of households with ≥1 contaminated surface. Mupirocin resistance did not increase. No significant improvements for patient-reported outcomes were seen.LIMITATIONSA lower-than-predicted six-month recurrence rate may have limited the ability to detect effects.CONCLUSIONThis intervention did not reduce clinician-reported MRSA/MSSA SSTI recurrence. No differences were observed for household members decolonization or household surfaces decontamination.
