Partner notification and treatment for sexually transmitted infections among pregnant women in Gaborone, Botswana

Spectrum of sexual partner types among adults screened for sexually transmitted infections in the Eastern Cape, South Africa

In South Africa, Chlamydia trachomatis prevalence is 14.7% in women and 6.6% in men, while Neisseria gonorrhoeae rates are 6.0% and 3.4%. Partner management, including identifying and screening for STIs, is essential for STI control efforts but challenging due to relationship dynamics, fear of disclosure and stigma. This study aims to understand how adults in the Eastern Cape report partner types when seeking STI care, enhancing partner notification strategies and reducing transmission. From February-August 2023, a cross-sectional evaluation of a Neisseria gonorrhoeae lateral flow assay was conducted among asymptomatic adults aged 18-49 years at four primary healthcare facilities in Buffalo City, Eastern Cape. Participants completed surveys classifying partners into LUSTRUM team's 8 partner types and 5 type-classifications. Data were analyzed using StataSE 17, examining associations between partner types and variables like gender, location, number of sexual partners, and STI test results. A total of 500 men and 400 women (median ages 31 and 32) were recruited. The most reported partner types were main/serious/long-term partners (41%) and girlfriend/boyfriend (29%) or LUSTRUM's 4: established (67%) and occasional partners (28%). Participants reporting main/long-term partners, steady, or boyfriend/girlfriend showed variability in partner numbers. Male adults more commonly reported casual partner types like friends with benefits (21% vs. 9%) and fuck buddy/booty call (9% vs. 3%), with significant associations for super casual/hook-up/meet/one-night stand (p = 0.02). Regional differences in partner types and a significant association between new partners and NG Xpert positivity (p = 0.01) were observed. This study confirms the diverse spectrum of sexual partner types. Findings reveal that men and women may have different relationships, and regional variations suggest context-specific approaches are needed. Identifying partner types can enhance communication and treatment strategies and address significant gaps in partner notification and STI care.

The effect of STI screening during pregnancy on vertical transmission of HIV and adverse pregnancy outcomes in South Africa: a modelling study

INTRODUCTION

Sexually transmitted infections (STIs) in pregnancy are associated with an increased risk of vertical HIV transmission and adverse pregnancy and birth outcomes. In South Africa, syndromic management is the standard of care for STI management. We assessed the potential impact of point-of-care (POC) screening for curable STIs (Chlamydia trachomatis [CT], Trichomonas vaginalis [TV] and Neisseria gonorrhoeae [NG]) during pregnancy on vertical HIV transmission and adverse pregnancy and birth outcomes.

METHOD

We developed a static mathematical model to estimate the impact of syndromic management compared to POC screening of STIs in pregnant women attending antenatal clinics in South Africa over one calendar year (2022). Our model assumptions regarding the effect of CT, NG and TV on adverse pregnancy/birth outcomes and vertical HIV transmission were informed by two separate meta-analyses that we conducted. Local studies informed estimates of STI prevalence, POC screening uptake and treatment, and sensitivity of syndromic management.

RESULTS

In the absence of POC screening for curable STIs, 25.5% of pregnant women without HIV and 34.6% of pregnant women living with HIV were estimated to have undiagnosed and untreated STIs. In the POC scenario, 92% (95% CI: 85-100%) of STIs were diagnosed and treated during pregnancy, reducing antenatal maternal HIV incidence by 10.0% (95% CI: 1.0-20.1%). Overall, vertical HIV transmission was anticipated to reduce by 8.6% (5.2-13.8%), with reductions of 20.9% (15.2-27.0%) at birth and 2.5% (-0.9% to 9.0%) postnatally, in the POC screening scenario compared to current syndromic management. POC screening of curable STIs is further estimated to reduce the incidence of stillbirth by 10.1% (1.3-18.7%), preterm delivery by 6.3% (3.4-9.7%), infants born small for gestational age by 2.7% (0.7-4.9%) and low birth weight by 9.1% (0.9-18%).

CONCLUSIONS

POC STI screening and treatment may modestly reduce maternal HIV incidence, vertical HIV transmission, and the risk of adverse pregnancy and birth outcomes, and would substantially reduce the burden of curable STIs in pregnancy. The study provides evidence to move beyond the syndromic management of STIs in South Africa, particularly in antenatal care.

Global perspectives on the burden of sexually transmitted diseases: A narrative review

Sexually transmitted diseases (STDs) pose a significant global health challenge with far-reaching social, economic, and public health implications. These infections have haunted humanity from ancient times to today, transcending geographical boundaries and cultural contexts. This article explores the multifaceted landscape of STDs, delving into their epidemiology, pathophysiology, clinical manifestations, and global response strategies. The global prevalence of STDs is staggering, with millions of new cases reported annually. Prominent among these infections is HIV/AIDS, which remains a major global health crisis, affecting over 38 million people worldwide. Additionally, bacterial STDs like chlamydia, gonorrhea, and syphilis continue to pose significant health risks, with millions of new cases reported yearly. Beyond the physical manifestations, STDs have profound social and economic implications. They can result in severe reproductive health issues, stigma, discrimination, and psychological distress, burdening healthcare systems and affecting individuals' quality of life. The global response to STDs has been multifaceted, with international organizations and governments implementing various prevention and control strategies, including sexual education programs and scaling up access to testing and treatment. However, challenges persist, including disparities in healthcare access, sociocultural factors influencing transmission, and evolving pathogens with increasing resistance to treatment. Through case studies and real-world examples, we illuminate the human stories behind the statistics, highlighting the lived experiences of individuals grappling with STDs and the complex interplay of factors shaping their journeys. Ultimately, this review calls for continued research, innovative strategies, and sustained global commitment to mitigating the burden of STDs and promoting sexual health and well-being for all.

Use of Expedited Partner Therapy for Pregnant Women Treated for Sexually Transmitted Infections in Gaborone, Botswana

BACKGROUND

Partner notification and treatment for sexually transmitted infections are critical to prevent reinfection and reduce transmission. However, partner treatment rates are low globally. Expedited partner therapy (EPT), in which the patient delivers treatment directly to their partner, may result in more partners treated. We assessed partner notification and treatment outcomes among pregnant women in Gaborone, Botswana, including EPT intent, uptake, and effectiveness.

METHODS

The Maduo study was a cluster-controlled trial evaluating the effect of antenatal Chlamydia trachomatis and Neisseria gonorrhoeae infection screening in pregnant women. The intervention arm received screening at first antenatal care (ANC), third-trimester, and postnatal care visits. The standard-of-care arm received screening postnatally. Participants screening positive were given options for partner treatment: contact slips, in-clinic treatment, or EPT. Self-reported partner notification and treatment outcomes were assessed at test-of-cure visit.

RESULTS

Of 51 women who screened positive for C. trachomatis / N. gonorrhoeae at first ANC and returned for test of cure, 100% reported notifying their partner and 48 (94.1%) reported their partner received treatment. At third trimester 100% (n = 5), reported partners were treated. Before testing, EPT intent was lower than EPT uptake at all time points (first ANC: 17.9% vs. 80.4%; third-trimester: 57.1% vs. 71.4%; postnatal care: 0% vs. 80.0%). Partner treatment success was 100% among EPT users compared with 70% among nonusers ( P = 0.006).

CONCLUSIONS

Partner notification and treatment success was high in this population. Despite low pretest intent to use EPT, uptake was high and associated with greater partner treatment success. Our findings suggest that EPT may be a successful partner treatment strategy to pursue in low- and middle-income countries.

Trichomoniasis and retesting in Durham County, North Carolina, United States, 2021 - 2022

BACKGROUND

The Centers for Disease Control and Prevention recommends universal retesting within 3 months after treatment of Trichomonas vaginalis infection given high rates of persistent infection or reinfection, or if this is not possible, within 12 months following treatment. Data is lacking on how often this is actually done.

METHODS

We analyzed the demographic and clinical characteristics, rate of return for the recommended retesting, concordance between wet prep and nucleic acid amplification testing, and percent positivity for T. vaginalis on repeat vaginal specimens at a local public health department in Durham, North Carolina, United States.

RESULTS

Of 193 females treated for trichomoniasis between March 1, 2021 - May 31, 2022, 83% were Black or African American and 44% between the ages of 20 and 29 years. Of these individuals, 32% had retesting performed within 3 months and 50% within 365 days after treatment. Females between the ages of 20 and 29 years were more likely to return for retesting than those between the ages of 30 and 39 years. Of those who returned for retesting, 10% were positive on repeat testing.

CONCLUSION

In this study, 50% of females diagnosed with trichomoniasis completed retesting within 365 days. Improved scheduling of clients at the time of trichomoniasis treatment and improved identification in our electronic health record of individuals diagnosed with trichomoniasis within the prior year would likely improve retesting rates. Given the high prevalence of trichomoniasis, expanded screening of asymptomatic females in settings where this is feasible may be warranted.

Resurgence of congenital syphilis: new strategies against an old foe

Congenital syphilis is a major global cause of fetal loss, stillbirth, neonatal death, and congenital infection. In 2020, the global rate of congenital syphilis was 425 cases per 100 000 livebirths-substantially higher than WHO's elimination target of 50 cases per 100 000 livebirths. Case rates are rising in many high-income countries, but remain low compared with those in low-income and middle-income settings. This Review aims to summarise the current epidemiology and knowledge on transmission and treatment of syphilis in pregnancy, and proposes measures to reduce the rising incidence seen worldwide. We also describe emerging diagnostic and treatment tools to prevent vertical transmission and improve management of congenital syphilis. Finally, we outline a programme of public health priorities, which include research, clinical, and preventive strategies.

Approach to Managing Sex Partners of People with Sexually Transmitted Infections

Partner management of sexually transmitted infection (STIs) is essential to identify and treat new cases, prevent reinfection in the index case, interrupt chains of transmission, reduce STI-related morbidity, and target STI screening and treatment interventions. The responsibility for partner notification and treatment falls on the health care provider. Approaches to partner management include patient referral, provider referral, contractual referral, and expedited partner therapy (EPT), with EPT and enhanced partner referral outperforming other methods. This article provides an overview of clinical recommendations regarding partner management, with particular emphasis on EPT, and an update on new and emerging evidence in the field.

Sexually transmitted infections in pregnant women from sub-Saharan Africa

Background

Sexually transmitted infections (STIs) are a major health problem in most countries of the world, particularly in developing countries where the resources and technology to diagnose and treat them are limited. Currently, there is limited data on STIs and risk factors for these infections in pregnant women living with human immunodeficiency virus (HIV), especially in sub-Saharan Africa (SSA). This review provides data on the prevalence and risk factors for STIs in pregnant women living with HIV from SSA. This review also describes the association between STIs and HIV on pregnancy and birth outcomes as well as highlights the importance of laboratory-based diagnosis of STIs.

Method

An electronic search of online databases was used to find and collect relevant research articles connected to the prevalence, adverse pregnancy and birth outcomes, health complications and risk factors associated with STIs and HIV in pregnant women from SSA. The search was limited to articles published in English. Relevant studies were identified by searching literature from January 2001 to date. The search yielded 4709 results.

Results

In SSA, STIs are highly prevalent in pregnant women and are widely known to be linked with an increased risk of poor maternal and neonatal outcomes. These infections are often asymptomatic and highly prevalent in pregnant women. The screening of STIs in pregnant women living with HIV can reduce the risk of mother-to-child transmission (MTCT) and screening and treatment for STIs can also prevent adverse perinatal outcomes. It is important to recognise regional and national STI epidemics in order to promote STI prevention and control interventions considering the test and treat approach as opposed to syndromic management.

Conclusion

This review highlights the need to use diagnostic screening methods instead of syndromic STI management in SSA. Moreover, more research into effective prevention and treatment measures for STIs in pregnant women is urgently required.

Gonorrhoea: a systematic review of prevalence reporting globally

BACKGROUND

The World Health Organization (WHO) recommends periodic gonorrhoea prevalence assessments in the general population or proxies thereof (including pregnant women, women attending family planning clinics, military recruits, and men undergoing employment physicals for example) and in population groups at increased risk, including men-who-have-sex-with-men (MSM) and sex workers.

METHOD

We evaluated reported prevalence data, including estimates from proxy general population samples to reflect the WHO recommendations. We describe the outcomes from the general population country-by-country and extend previous reviews to include MSM, sex workers, and extragenital infections.

RESULT AND CONCLUSION

In our systematic search, 2015 titles were reviewed (January 2010-April 2019) and 174 full-text publications were included. National, population-based prevalence data were identified in only four countries (the United States of America, the United Kingdom, Peru, New Caledonia) and local population-based estimates were reported in areas within five countries (China, South Africa, Brazil, Benin, and Malawi). The remaining studies identified only reported test positivity from non-probability, proxy general population samples. Due to the diversity of the reviewed studies, detailed comparison across studies was not possible. In MSM, data were identified from 64 studies in 25 countries. Rectal infection rates were generally higher than urogenital or pharyngeal infection rates, where extragenital testing was conducted. Data on sex workers were identified from 41 studies in 23 countries; rates in female sex workers were high. Current prevalence monitoring was shown to be highly suboptimal worldwide. Serial prevalence monitoring of critical epidemiological variables, and guidelines to optimize prevalence study conduct and reporting beyond antenatal settings are recommended.

A review on Trichomonas vaginalis infections in women from Africa

Background

Trichomoniasis is the most common sexually transmitted infection (STI) with an estimated annual incidence of 276.4 million cases globally and about 30 million cases in sub-Saharan Africa. Trichomoniasis has been found to be associated with various health complications including pelvic inflammatory disease (PID), significant pregnancy complications, cervical cancer, prostatitis, infertility and the acquisition of human immunodeficiency virus (HIV).

Aim

Despite being a highly prevalent infection in the African continent, there is no review article published that solely focusses on Trichomonas vaginalis (T. vaginalis) infections in women from Africa. This review aims to fill this gap in the literature.

Method

An electronic search of online databases was used to identify and extract relevant research articles related to the epidemiology, health complications and treatment associated with T. vaginalis in women from Africa.

Results

Within the African continent, South Africa has reported the highest prevalence rate for this infection. A combination of sociodemographic, behavioural and biological factors has been shown to be associated with infection. Trichomonas vaginalis infection is associated with the acquisition of HIV, cervical cancer and PIDs in various female populations across the continent. Emerging patterns of resistance to metronidazole have been reported in women from South Africa. Currently, there is no effective vaccine against this pathogen despite efforts at vaccine development.

Conclusion

Based on the high prevalence and health consequences associated with T. vaginalis, there is a need for improved screening programmes that will lead to early diagnosis, detection of asymptomatic infections and effective treatment regimens.

Experiences and preferences with sexually transmitted infection care and partner notification in Gaborone, Botswana

Partner notification and treatment are essential to sexually transmitted infection (STI) management. However, in low- and middle-income countries, half of partners do not receive treatment. A mixed methods study was conducted to explore experiences and preferences around partner notification and treatment in patients seeking STI care in Gaborone, Botswana. Thirty participants were administered a quantitative survey, followed by a semi-structured interview on partner notification, treatment, and expedited partner therapy (EPT). Among the 30 participants, 77% were female with a median age of 28 years (IQR = 24-36), 87% notified their partner, and 45% of partners requiring treatment received treatment. Partners who received a contact slip were more likely to have been treated than those who did not (75% vs. 25%). Contact slips were identified as facilitators of notification and treatment, while asymptomatic partners and limited clinic resources were identified as barriers to treatment. Few participants expressed a preference for EPT and concerns included preference for medical supervision, a belief their partner would refuse, and an inability to explain the treatment. Despite successful notification, partner treatment was modest within this population. Information for partners, provider counseling, and improved access to services may increase partner treatment. Education on STIs and treatment options may improve EPT acceptability.

Partner notification and treatment for sexually transmitted infections among pregnant women in Cape Town, South Africa

Curable sexually transmitted infections (STIs) including Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and Trichomonas vaginalis (TV) are associated with adverse pregnancy outcomes. Partner notification is an important component of STI control as it has been shown to prevent re-infection and reduce infectious burden. Between October 2017 and February 2019, we conducted a cohort study of women attending antenatal care in Cape Town, South Africa. Self-collected vulvovaginal swabs were tested for CT, NG, and TV using Xpert® assays at first antenatal visit, during the third trimester, and postpartum. At the visit following a positive diagnosis, women were asked if they notified their partner and if their partner was treated. Among 242 participants, 97% reported being willing to notify partners if they tested positive and 78% thought their partner would be willing to treat the STI. Of the 73 women who were diagnosed with one or more STIs and reported having a sex partner, 93% reported notifying their partner and 63% reported their partner was treated. Younger maternal age was associated with partner notification and treatment (OR = 3.82; 95%CI = 1.34-10.90). Acceptability of partner notification was high in pregnant women, but partner treatment was low. Future interventions to improve partner notification and treatment are needed.

Contact tracing of syphilis-seropositive pregnant women and syphilis-infection among their male partners in Bao'an district, Shenzhen, China

Background

Untreated male partners are a critical source of maternal re-infection. Contact tracing is a good way to identify infection among partners and reduce risk of mother-to-child transmission related to maternal re-infection. This study aimed to analyze the current situation and related factors of contact tracing of syphilis-seropositive pregnant women and syphilis-infection among their male partners.

Method

Data of syphilis-seropositive pregnant women and their male partners attending clinic for syphilis-screening were obtained from the Shenzhen Program for Prevention of Congenital Syphilis. Contact tracing rate of syphilis-seropositive pregnant women and syphilis prevalence among male partners were counted, and related factors were also analyzed using a random-effects logistic regression model.

Result

Of the 1299 syphilis-seropositive pregnant women, 74.1% (963/1299) had their male partners receiving syphilis-screening and 19.1% (184/963) of male partners were syphilis-infected. For pregnant women, being divorced (adjusted odds ratio [AOR] =0.39; 95%CI: 0.17–0.87), seeking for emergency services at their first antenatal clinics visits (AOR = 0.58; 95%CI: 0.44–0.77), reporting willingness to notify partner(AOR = 7.65; 95%CI: 4.69–12.49), multi-partners (AOR = 1.38; 95%CI:1.03–1.86) and having a history of drug abuse (AOR = 0.37; 95%CI: 0.14–1.00)were independently associated with successful contact tracing. For male partners, of minority ethnicity (AOR = 4.15; 95%CI: 1.66–10.34), age at first sex>20(AOR = 0.57; 95%CI: 0.37–0.87), reporting multi-partners (AOR = 1.60; 95%CI: 1.04–2.46), having a history of drug abuse (AOR = 4.07; 95%CI: 1.31–12.64) were independently associated with syphilis-infection. In addition, pregnant women with TRUST titer ≥1:8 (AOR = 2.81; 95%CI: 1.87–4.21), having a history of adverse pregnancy outcomes (AOR = 1.70; 95%CI: 1.14–2.53), reporting multi-partners (AOR = 0.43; 95%CI: 0.29–0.64) and reporting the current partner as the source of syphilis (AOR = 5.05; 95%CI: 2.82–9.03) were independently associated with partners’ syphilis-infection.

Conclusion

Contact tracing is feasible and effective in identifying syphilis-infected partners among syphilis-seropositive pregnant women. Contact tracing is associated with many factors such as women’s marital status, services at their first antenatal clinics visit and willingness of partner notification. Partners’ ethnicity, age at first sex, multi-partners and history of drug abuse as well as women’s levels of TRUST titer were associated with partners’ syphilis-infection.

High Willingness to Participate in Partner Notification among Women Attending Reproductive Health and STI Clinics in Shenzhen, China: A Cross-Sectional Study

Genital Chlamydia trachomatis (CT) is one of the most common sexually transmitted infections (STI) worldwide. We explored the factors associated with willingness to participate in partner notification (PN) among women attending reproductive health and STI clinics in Shenzhen, China. An anonymous questionnaire was used to collect the sociodemographic characteristics, STI histories, and willingness to participate in routine CT screening and partner notification. In total, 87.31% (n = 10,780) of participants were willing to notify their sex partner(s) if they were diagnosed with a CT infection. Willingness to complete PN was significantly associated with: being married, residing in Shenzhen ≥1 year, having completed junior college or higher, not currently reporting STI-related symptoms, willing to have routine CT screening, and having a correct understanding of the health sequelae of CT infection. Nearly all women surveyed at reproductive health and STI clinics in Shenzhen reported willingness to complete PN. Promoting PN in these settings could help detect a large number of additional CT cases. Our findings provide evidence and implications for public health interventions on PN and suggest that targeted interventions are urgently needed for particular subpopulations including those not currently married, with shorter residency, lower education, and less awareness about the dangers of CT infection.

[Compliance with the partner notification of HIV/STI patients in the counties of Lleida]

OBJECTIVE

The partner notification is one of the main activities of epidemiological surveillance in Public Health. The primary objective was to estimate the compliance of the partner notification by health professionals who reported sexually transmitted diseases (HIV, Gonorrhoea, Syphilis and Chlamydia) during 2017 in Lleida's regions.

METHODS

We carried out a descriptive epidemiological study of prevalence about the compliance of partner notification. Data collection was done by epidemiological surveys of these notifiable diseases and additional information was recovered through medical record and interview with professionals. The factors associated with the lack of partner notification were studied through the odds ratio (OR) and its 95% confidence interval (CI). ORs were adjusted (ORa) with multivariate logistic regression models.

RESULTS

We studied 203 STD cases with an average age of 30.6 years (SD=11.1); 32.5% were women. There was 46.3% without partner notification. The main cause of this absence was the lack of patient cooperation (23.4%). The variables associated with the lack of partner notification were the male sex (aOR-3.5; CI95%=1.6-7.5), gonococcal infection (aOR-4.9; CI95%=1.2-19.8), chlamydia infection (aOR-3.9; CI95%=0.9-16.1) and homosexual/bisexual sexual orientation (aOR-2.2; CI95%=0.9-5.4).

CONCLUSIONS

Compliance of partner notification is low and it is related to male sex, sexual orientation (homosexual/bisexual/transsexual) and type of infection (Gonorrhoea and Chlamydia). Reducing the social stigma associated with sexual orientation and improving the information of health professionals could favour the contact studies.

Acceptability and efficacy of partner notification for curable sexually transmitted infections in sub-Saharan Africa: A systematic review

Comprehensive case management of sexually transmitted infections (STIs) includes partner notification. We reviewed the recent literature evaluating the acceptability and efficacy of partner notification strategies (i.e. direct patient referral, provider referral, or expedited partner treatment) for curable STIs in sub-Saharan Africa. We conducted a systematic search following PRISMA guidelines: published January 2008 to June 2017 in the English language, study in sub-Saharan Africa, and discussion of any curable STI with an outcome on partner notification. We searched six electronic databases, conference abstracts, online clinical trial registries, and article bibliographies. The results showed that out of the 74 identified articles, 55 did not meet inclusion criteria. Of the 11 studies evaluating direct patient referral, the proportion of index cases ( n = 4163) who successfully notified sex partner(s) was 53% (range 23-95%). Among those who notified ( n = 1727), 25% (range 0-77%) had partner(s) that sought evaluation (95% CI 0.51-0.54; 95% CI 0.23-0.27). Both provider referral and expedited partner treatment had higher proportions of partner(s) who sought treatment ( n = 208, 69% and n = 44, 84%, respectively). Direct patient referral is the most commonly used and evaluated partner notification strategy for STIs in sub-Saharan Africa with mixed success. We recommend future research to investigate other strategies such as expedited partner treatment.

Lack of Virological Suppression Among Young HIV-Positive Adults in Botswana

BACKGROUND

HIV-1 RNA load is the best biological predictor of HIV transmission and treatment response. The rate of virologic suppression among key subpopulations can guide HIV prevention programs.

METHODS

The Botswana Combination Prevention Project performed a population-based household survey among adults in 30 communities in Botswana. Data collected included knowledge of HIV-positive status, antiretroviral therapy (ART) coverage, and virologic suppression (HIV-1 RNA ≤400 copies per milliliter). Individuals aged 16-29 years were considered young adults.

RESULTS

Among 552 young people living with HIV enrolled with RNA load data and ART status available, 51% (n = 279) had undetectable HIV-1 RNA, including 54% of young women and 32% of young men [sex prevalence ratio (PR): 0.53; 95% confidence interval (CI): 0.43 to 0.80; P < 0.001]. Compared with older adults (30-64 years old), young HIV-infected adults were significantly less likely to have undetectable HIV-1 RNA (PR: 0.65; 95% CI: 0.59 to 0.70; P < 0.0001), including both men (PR: 0.43; 95% CI: 0.34 to 0.56; P < 0.0001) and women (PR: 0.67; 95% CI: 0.62 to 0.74; P < 0.0001). Among a subset of people living with HIV receiving ART, young adults also were less likely to have undetectable HIV-1 RNA load than older adults (PR: 0.93; 95% CI: 0.90 to 0.95; P = <0.0001). Analysis of the care continuum revealed that inferior HIV diagnosis and suboptimal linkage to care are the primary reasons for low virologic suppression among young adults.

CONCLUSIONS

Young adults in Botswana are significantly less likely to have undetectable HIV-1 RNA load compared with older adults. In the era of broad scale-up of ART, interventions able to diagnose young adults living with HIV and link them to effective therapy are urgently needed.
