J Int AIDS Soc 2025 28 Suppl 1 e26469 INTRODUCTION: Sexual violence (SV) affects millions globally and has a well-documented bidirectional association with HIV. Post-exposure prophylaxis (PEP) is a critical, yet often underutilized, HIV prevention tool in post-SV care. Despite its potential impact to reduce HIV transmission, SV care remains an overlooked service delivery point for HIV prevention. The U.S. Centers for Disease Control and Prevention (CDC), as part of the President's Emergency Plan for AIDS Relief (PEPFAR), supports PEP provision within broader post-violence care (PVC) services. Understanding PEP utilization is crucial for optimizing service delivery and HIV prevention efforts. METHODS: Using Monitoring Evaluation and Reporting data from fiscal years 2018-2023, we conducted a descriptive analysis of clients who received PVC and SV services through CDC-supported programming in 14 sub-Saharan African countries. RESULTS: From 2018 to 2023, the annual number of clients receiving any PVC, and specifically SV, services increased by 233% (in 2018, n = 206,764; in 2023, n = 689,349) and 163% (in 2018, n = 42,848; in 2023, n = 112,838), respectively. Fewer than half of SV clients completed PEP (38% in 2018, n = 16,103; 31% in 2023, n = 35,118). Across all years combined, most SV clients (female: 185,414; male: 59,618) were aged 15-19 years. The age band and sex with the lowest proportion of clients completing PEP were males aged 15-19 (4%, n = 2296). CONCLUSIONS: The findings underscore a critical gap between the scaling of SV services and the completion of PEP within violence response programmes. Innovative implementation science approaches may help to identify and address barriers inhibiting effective PEP delivery and uptake within PVC service delivery programmes. Enhancing PEP uptake and completion can support mitigating the bidirectional relationship between violence and HIV acquisition, particularly among vulnerable populations like adolescents and young adults. Low PEP coverage also reflects missed opportunities, particularly among adolescent girls and young women, who experience disproportionate rates of HIV acquisition. |
| Efforts to link HIV-positive and high-risk blood donors to HIV testing, and treatment services, Mozambique, 2019-2020
Kanagasabai U , Sousa L , Chevalier MS , Gutreuter S , Ibraimo D , Salimo S , Naueia E , Daniel L , Khan S , Ujamma D , Behel S , Malimane I , Drammeh B . Sci Rep 2025 15 (1) 20730 Mozambique's National Blood Transfusion Services (NBTS) is tasked with providing safe and available blood but also conducting systematic screening of at-risk potential donors, notifying seropositive blood donors, and linking them to HIV care and treatment services. Potential blood donors who were deferred from donating following a behavioral risk screening and all blood donors who screened seropositive for HIV were notified and offered linkage to HIV testing, care, and treatment services by community-based organizations. A prospective study among HIV-positive blood donors and deferred donors was conducted from May 2019 to July 2020 at Maputo Central Hospital Blood Bank and the National Reference Blood Center. The associations between testing, initiating care and treatment services among HIV-positive blood donors and prospective deferred donors were estimated using fully Bayesian multivariable logistic models and odds ratios. Among 885 prospective blood donors enrolled, 173 (20%) were deferred due to self-reported high-risk behaviors identified through a screening questionnaire, and 712 (80%) passed the behavioral-risk screening tool, donated, and the blood donation tested positive for HIV. There were more than 2.5 times as many male donors as female donors with a positive HIV test, and among the deferred donors, more than 84% were males. 36% (256/712) of seropositive donors and 35% (61/173) of deferred donors were referred to HIV testing services. 62% (158/256) of seropositive donors and 4.9% (3/61) of deferred donors who were successfully referred were linked to care and treatment services, and 96% (152/158) of these seropositive donors and 100% (3/3) of deferred as high-risk donors initiated antiretroviral therapy (ART). Of the three service organizations used, one outperformed the other two in linking seropositive donors to ART treatment. The NBTS can serve as a critical entry point for identifying HIV-positive persons. Improved implementation of risk behavior screening tools is needed and could contribute to early identification and initiation of ART for potential donors. Innovative strategies and solutions by community-based organizations can be used to improve blood donor notification and linkage to HIV testing and treatment services. |

Laterra A , Miedema SS , Li M , Mndzebele P , Nzuza-Motsa N , Charania SN , Ong K , Cain M , Kanagasabai U , Mkhonta T , Chiang L , Annor FB , Adler MR . J Int AIDS Soc 2025 28 Suppl 1 e26486 INTRODUCTION: In Eswatini, HIV incidence among adolescent girls and young women (AGYW), aged 15-24 years, is 10 times that of their male peers. Despite the World Health Organization's 2014 recommendation for post-exposure prophylaxis (PEP) to be available for all HIV exposures, it has been underutilized among youth. PEP is an effective prevention method, and a better understanding of the characteristics, risk factors and behaviours that are associated with PEP awareness, as a precursor to effective use, is needed. METHODS: Using data from the 2022 Eswatini Violence Against Children and Youth Survey, we used logistic regression models to explore the relationships between PEP awareness and a set of hypothesized explanatory variables among AGYW aged 13-24 years who had ever had sex (N = 2648). Explanatory variables included socio-demographic characteristics, sexual risk factors and sexual health behaviours. RESULTS: A slight majority (57.3%) of AGYW who had ever had sex were aware of PEP as an HIV prevention method. PEP awareness increased with age (aOR 1.1, 95% CI 1.0, 1.1) and was higher among AGYW who had a sexual partner whose age was 5 or more years older in the past 12 months (aOR 1.4, 95% CI 1.1, 1.9), those who had ever taken part in an HIV prevention programme (aOR 1.6, 95% CI 1.2, 2.3) and those who had ever heard of pre-exposure prophylaxis (aOR 8.1, 95% CI 6.4, 10.2). Participants who were ever married or partnered (aOR 0.7, 95% CI 0.5, 1.0) and those who engaged in inconsistent condom use with non-spouse/main partner or multiple partners in the past 12 months (aOR 0.8, 95% CI 0.6, 1.00) had lower odds of knowing about PEP in the adjusted model. CONCLUSIONS: We identified sub-optimal PEP awareness among Swazi AGYW who had ever had sex. Our findings suggest that engagement in HIV prevention programmes increased PEP awareness and that knowing about pre-exposure prophylaxis (PrEP) was associated with PEP awareness. Future efforts could include tailored PEP awareness activities and campaigns to resonate with AGYW at elevated risk of HIV and integration of PEP education into routine sexual and reproductive service delivery and school-based HIV curriculum. |
| Strengthening post-exposure prophylaxis uptake among survivors of sexual violence through immediate access at police stations in Nigeria's Federal Capital Territory
Adewumi B , Cain M , Kanagasabai U , Dahal S , Collins-Kalu D , Ayuba AM , Adamu V , Efuntoye T , Ayeni C , Omuh H , Nwafor C , Ajuwon AR , Oluwaniyi O , Dakum P , Oki-Emesim R , Daggash F , Fagbamigbe O . J Int AIDS Soc 2025 28 Suppl 1 e26460 INTRODUCTION: Data on sexual violence (SV) prevalence in Nigeria is limited; however, 2014 data indicate that 24.8% of females aged 18-24 years experienced SV in childhood and only 3.5% received any form of services. Initiation of post-exposure prophylaxis (PEP) to prevent HIV acquisition following SV is most effective when started immediately and is not recommended after 72 hours. Police stations are often entry points for survivors; however, lengthy processes may result in delays and missed PEP opportunities. Using an ongoing phased approach, we introduced PEP into selected police stations in Nigeria's Federal Capital Territory in order to explore expanding access to time-sensitive HIV prevention within non-health services. METHODS: Our intervention phase consisted of the provision of training of police officers and the provision of PEP starter packs coupled with linkage to referral facilities. During two time periods (pre-intervention: January-March 2023) and (during intervention: July-September 2023), we evaluated routinely reported programme data from 27 U.S. Centers for Disease Control and Prevention-supported health facilities for changes in the provision of SV services and PEP initiation. We used geospatial mapping to assess the proximity of participating health facilities to police stations and to see changes in both SV and PEP service provision. The statistical significance of the difference in PEP uptake proportion during the two periods was determined using the Wilcoxon signed rank test at a 0.05 level of significance. RESULTS: Of the total 27 health facilities, 24 were within a 5-km radius of a participating police station. Total SV service provision increased from 114 cases to 218 cases, representing a 91.2% increase and with most of this increase seen among females. PEP initiation increased by 289.3% at the two time points, with 56 initiations pre-intervention to 218 PEP initiations during the intervention. CONCLUSIONS: Our findings showed promise in increasing immediate access to PEP in non-health services and highlighted the feasibility of police stations and health facilities collaboration to address urgent health needs. There was an overall increase in PEP initiations by referral and non-referral facilities which could be the result of demand creation and increased access at police stations. |

Kanagasabai U , Thorsen V , Zhu L , Annor FB , Chiang L , McOwen J , Augusto A , Manuel P , Kambona C , Coomer R , Kamagate F , Ramphalla P , Denhard L , Cain M , Hegle J , de Barros RB , Saenz S , Kamami M , Patel P . Child Abuse Negl 2023 106541 BACKGROUND: Adverse childhood experiences (ACEs) have been shown to have negative, lasting effects on health including increasing the likelihood of engaging in sexual risk behaviors. OBJECTIVE: This study aimed to identify associations between exposures to ACEs and sexual risk behaviors and HIV service utilization among young people. PARTICIPANTS AND SETTING: A sample of 8023 sexually active young people (19-24 year olds) from five sub-Saharan African countries participated Violence Against Children and Youth Surveys (VACS). METHODS: Descriptive analysis of demographic variables, individual ACEs, cumulative ACEs, sexual risk behaviors, HIV testing, antiretroviral treatment (ART) and Antenatal Care (ANC) attendance were completed. Bivariate and multivariable logistic regression analyses were conducted to assess the associations between both individual and cumulative ACEs, sexual HIV risk behaviors, and service utilization while controlling for important covariates such as demographic, having ever been pregnant, had an STI, and used contraception. RESULTS: Exposure to three or more ACEs was higher among males (26.1 %) compared to females (21.3 %); p = 0.003. The most prominent sexual risk behavior for females was having sexual partners who were at least 5 years older (45.7 % compared to males 3.7 %; p < 0.0001) whereas in males it was no or infrequent condom use (45.3 % compared to females 30.1 %; p < 0.0001). Males and females exposed to childhood sexual violence had seven and four times the odds of engaging in transactional sex (aOR = 7.34, 95 % CI: [3.5-15.0]) and (aOR =3.75, 95 % CI: [2.3-6.2], respectively. Females exposed to three or more ACEs were four times more likely to engage in transactional sex (aOR = 4.85, 95 %, CI: [1.6-14.4]) compared to those who did not experience any ACEs. Males exposed to three or more ACEs were two times more likely to engage in early sexual debut (aOR = 2.2, 95 % CI: [1.3-3.4]),]) compared to those who did not experience any ACEs. Females who had witnessed IPV or violence in the community had significantly higher odds of getting tested for HIV (aOR = 2.16, 95 % CI: [1.63-2.87]) and (aOR = 1.36, 95 % CI: [1.03-1.81]), respectively. CONCLUSIONS: This study demonstrated that experiencing ACEs during childhood is associated with higher HIV risk behaviors in sub-Saharan Africa (SSA) with unique differences between males and females. |
| Service-seeking behaviors among male victims of violence in five African countries: The effects of positive and adverse childhood experiences
Denhard L , Brown C , Kanagasabai U , Thorsen V , Kambona C , Kamagate F , Ramphalla P , Benevides R , Kamami M , McOwen J , Augusto A , Manuel P , Coomer R , Matthews S , Patel P , Annor FB . Child Abuse Negl 2023 106452 BACKGROUND: Violence against boys and men is widely under-reported. Boys and men face unique and gendered barriers to accessing services following experiences of violence. PARTICIPANTS AND SETTING: The study is a secondary data analysis of five nationally representative population-based Violence Against Children and Youth Surveys (VACS) conducted in Kenya (2019), Côte d'Ivoire (2018), Lesotho (2018), Mozambique (2019), and Namibia (2019). Analysis was limited to males between 18 and 24 years who experienced lifetime physical or sexual violence. OBJECTIVE AND METHODS: We analyzed the association between positive and adverse childhood experiences (PCEs and ACEs), and seeking post-violence services among males using bivariate chi-squared tests and multivariable logistic regression. RESULTS: 8.02 % (5.55-10.50 %) of male victims between the ages of 18 and 24 sought services for any lifetime physical or sexual violence. Witnessing interparental violence and experiencing death of one or both parents were each associated with increased odds of having sought post-violence services (aOR 2.43; 95 % CI: 1.25-4.79; aOR 2.27; 95 % CI: 1.14-4.50), controlling for education, violence frequency, and violence type. High parental monitoring was associated with increased odds of service seeking (aOR 1.79; 95 % CI: 1.02-3.16), while strong father-child relationship was associated with lower odds (aOR 0.45; 95 % CI: 0.23-0.89). CONCLUSION: These findings contribute to limited research on service-seeking behaviors among men and boys. While some parent-youth relationship factors were associated with higher odds of service-seeking, the outcome remained rare. Age and gender-related barriers should be addressed where post-violence care services are offered. |
| Reaching youth through faith leaders: Evaluation of the Faith Matters! Initiative
Kanagasabai U , Aholou T , Chevalier MS , Tobias JL , Okuku J , Shiraishi RW , Sheneberger R , Pande YC , Chifuwe C , Mamane LE , Njika G , Obongo C , Thorsen VC . AIDS Educ Prev 2023 35 82-99 Faith leaders can be uniquely positioned to guide and support young people on health issues, particularly HIV/AIDS and sexual violence. Faith Matters!, a 2-day training workshop for faith leaders, was delivered in September 2021 in Zambia. Sixty-six faith leaders completed a questionnaire at baseline, 64 at posttraining, and 59 at 3-month follow-up. Participants' knowledge, beliefs, and comfort communicating about HIV/AIDS and sexual violence were assessed. More faith leaders accurately identified common places where sexual violence occurs at the 3-month point compared to baseline: at church (2 vs. 22, p = .000), the fields (16 vs. 29, p = .004), parties (22 vs. 36, p = .001), and clubs (24 vs. 35, p = .034). More faith leaders stated that they engaged in conversations that supported people living with HIV (48 at baseline vs. 53, p = .049 at 3-month follow-up). These findings can inform future HIV/AIDS initiatives focusing on increasing the capacity among communities of faith. |
| Understanding gender-based violence service delivery in CDC-supported health facilities: 15 Sub-Saharan African Countries, 2017-2021

AIDS Educ Prev 2023 35 39-51 Gender-based violence (GBV) is a complex issue deeply rooted in social structures, making its eradication challenging. GBV increases the risk of HIV transmission and is a barrier to HIV testing, care, and treatment. Quality clinical services for GBV, which includes the provision of HIV postexposure prophylaxis (PEP), vary, and service delivery data are lacking. We describe GBV clinical service delivery in 15 countries supported by the President's Emergency Plan for AIDS Relief (PEPFAR) through the U.S. Centers for Disease Control and Prevention. Through a descriptive statistical analysis of PEPFAR Monitoring, Evaluation, and Reporting (MER) data, we found a 252% increase in individuals receiving GBV clinical services, from 158,691 in 2017 to 558,251 in 2021. PEP completion was lowest (15%) among 15-19-year-olds. Understanding GBV service delivery is important for policy makers, program managers, and providers to guide interventions to improve the quality of service delivery and contribute to HIV epidemic control. |
| From policy to practice: uptake of pre-exposure prophylaxis among adolescent girls and young women in United States President's Emergency Plan for AIDS Relief-supported countries, 2017-2020
Patel P , Sato K , Bhandari N , Kanagasabai U , Schelar E , Cooney C , Eakle R , Klucking S , Toiv N , Saul J . AIDS 2022 36 S15-s26 BACKGROUND: The US President's Emergency Plan for AIDS Relief's (PEPFAR) first implemented pre-exposure prophylaxis (PrEP) for HIV prevention through the Determined, Resilient, Empowered, AIDS-Free, Mentored and Safe (DREAMS) partnership in 2016. PrEP is a critical intervention to achieve the main objective of DREAMS, reducing new HIV infections among 15-14 year old adolescent girls and young women (AGYW) in 15 high HIV burdened countries. METHODS: We describe uptake of PrEP among AGYW in PEPFAR. Most PrEP programs screened persons who tested HIV-negative for eligibility and offered PrEP as part of combination prevention with follow-up, including repeat HIV testing and counseling, at 3-month intervals. Platforms providing comprehensive services for AGYW were also leveraged. We examined two PEPFAR monitoring indicators, using the FY20Q4 Monitoring, Evaluation, Reporting (MER) indicator dataset to assess progress in PrEP uptake, and descriptive narratives to understand successes and challenges from fiscal year 2017 to 2020. To assess coverage, we calculated the PrEP to Need ratio (PnR) using a published methodology. RESULTS: From FY2017 to FY2020, 576570 total clients initiated PrEP and the number of PEPFAR countries offering PrEP doubled from 12 to 24. Of 360073 (62% of total) initiations among women, 52% were among AGYW with steady increases from year to year. Among all AGYW, 20-24-year-old women represented a significantly higher proportion of PrEP initiators than adolescents (15-19years) (64 versus 36%, P < 0.05). Of all 186985 PrEP initiations among AGYW, 99% were in DREAMS countries. Barriers, such as low demand and adherence, were addressed through outreach efforts, including mobile sites, use of technology to educate and support AGYW, media campaigns, and engaging peers in program implementation. We saw a 2.5-fold increase in PrEP uptake among AGYW from 2018 to 2019; by 2020, all DREAMS countries were implementing PrEP. However, PrEP coverage among AGYW in DREAMS countries remains low (PnR range: 0-4.1); only two have a PnR greater than 1 where there were more PrEP users than new HIV diagnoses. CONCLUSION: PrEP uptake among AGYW has grown since 2016; however, challenges remain. Tools to improve adherence are needed to improve PrEP persistence among AGYW. National policies to facilitate greater PrEP uptake among adolescents would be beneficial. A greater need for PrEP in DREAMS countries is evident and if realized, will contribute to epidemic control. |
| Baseline assessment findings of the Africa Society for Blood Transfusion Step-Wise Accreditation Programme in 10 sub-Saharan African countries, 2016-2018
Kanagasabai U , Qualls M , Shiraishi RW , Eno L , Zungu I , Bust L , Drammeh B , Selenic D . Vox Sang 2022 117 (6) 839-846 BACKGROUND AND OBJECTIVES: The accreditation of blood services promotes continuous quality improvement in blood and transfusion services. The Africa Society for Blood Transfusion (AfSBT) conducted 20 baseline assessments of National Blood Transfusion Services (NBTS) or blood banks as part of the Step-Wise Accreditation Programme (SWAP) in 10 sub-Saharan African (SSA) countries from 2016 to 2018. This paper aims to elucidate the process and findings of the baseline assessments. MATERIALS AND METHODS: This is a descriptive study of 20 baseline assessments of NBTS. Eleven sections of the AfSBT assessment were reviewed, and 48 out of 68 standards and 356 out of 466 criteria were assessed. Each standard was assigned a value of 1 if it was fully achieved, 0.5 if partially achieved and 0 if not achieved. We defined average section scores >75% as having 'met AfSBT Standards', 25% as not meeting standards, 26%-50% as needs major improvement, and 51%-75% as needs some improvement and >75% as meets standards. RESULTS: The AfSBT SWAP standards were met in 4 out of the 11 sections: donor management, blood collection, component production and compatibility testing. Three sections were determined to need some improvement (quality system; handling, transport and storage and testing of donated blood), and three sections were determined to need major improvement (haemovigilance, blood administration and national blood service accreditation). One section (receipt, ordering, and issuing of blood) did not meet standards. CONCLUSION: Despite improvements in the quality of blood services in SSA over the past two decades, governments may consider the importance of prioritizing investments in NBTS, ensuring these institutions meet international accreditation standards that are aligned with safe blood transfusion services. |
| The impact of water sanitation and hygiene (WASH) improvements on hand hygiene at two Liberian hospitals during the recovery phase of an Ebola epidemic
Kanagasabai U , Enriquez K , Gelting R , Malpiedi P , Zayzay C , Kendor J , Fahnbulleh S , Cooper C , Gibson W , Brown R , Nador N , Williams DE , Chiriboga D , Niescierenko M . Int J Environ Res Public Health 2021 18 (7) Fourteen years of civil war left Liberia with crumbling infrastructure and one of the weakest health systems in the world. The 2014–2015 Ebola virus disease (EVD) outbreak exposed the vulnerabilities of the Liberian health system. Findings from the EVD outbreak highlighted the lack of infection prevention and control (IPC) practices, exacerbated by a lack of essential services such as water, sanitation, and hygiene (WASH) in healthcare facilities. The objective of this intervention was to improve IPC practice through comprehensive WASH renovations conducted at two hospitals in Liberia, prioritized by the Ministry of Health (MOH). The completion of renovations was tracked along with the impact of improvements on hand hygiene (HH) practice audits of healthcare workers pre-and post-intervention. An occurrence of overall HH practice was defined as the healthcare worker practicing compliant HH before and after the care for a single patient encounter. Liberia Government Hospital Bomi (LGH Bomi) and St. Timothy Government Hospital (St. Timothy) achieved World Health Organization (WHO) minimum global standards for environmental health in healthcare facilities as well as Liberian national standards. Healthcare worker (HCW) overall hand hygiene compliance improved from 36% (2016) to 89% (2018) at LGH Bomi hospital and from 86% (2016) to 88% (2018) at St. Timothy hospital. Improved WASH services and IPC practices in resource-limited healthcare settings are possible if significant holistic WASH infrastructure investments are made in these settings. |
| Improving injection safety practices of Cambodian healthcare workers through training
Kanagasabai U , Singh A , Shiraishi RW , Ly V , Hy C , Sanith S , Srun S , Sansam S , SopHeap ST , Liu Y , Jones G , Ijeoma UC , Bock N , Benech I , Selenic D , Drammah B , Gadde R , Mili FD . PLoS One 2020 15 (10) e0241176 BACKGROUND: This study evaluated the impact of a safe injection safety training on healthcare worker (HCW) practice and knowledge following an HIV outbreak in Roka commune, Cambodia. METHODS: Surveys were conducted at baseline (September 2016) and seven months after a training intervention (March 2018) using the World Health Organization standardized injection practices assessment tool. HCWs were sampled at 15 purposively government health facilities in two provinces. HCWs were observed during injection practices and interviewed by trained experts from Becton-Dickinson and the Ministry of Health Cambodia. The Rao-Scott chi square test was used test for differences between baseline and follow-up. RESULTS: We completed 115 observations of practice at baseline and 206 at post-training follow-up. The proportion of patients whose identification was confirmed by HCWs prior to procedure being performed increased from 40.4% to 98% (p <0.0001). The proportion of HCWs who practiced correct hand hygiene increased from 22.0% to 80.6% (p = 0.056) [therapeutic observations] and 17.2% to 63.4% (p = 0.0012) [diagnostic observations]. Immediate disposal of sharps by HCWs decreased from 96.5% to 92.5% (p = 0.0030). CONCLUSIONS: We found significant improvements in the practice of patient identity confirmation and hand hygiene but not in the immediate disposal of sharps in the post-training intervention. However, findings are not representative of all HCWs in the country. Further pre-service and in-service training and monitoring are necessary to ensure sustained behavior change. |
| Evaluation of the WHO global database on blood safety
Kanagasabai U , Selenic D , Chevalier MS , Drammeh B , Qualls M , Shiraishi RW , Bock N , Benech I , Mili FD . Vox Sang 2020 116 (2) 197-206 OBJECTIVE: While the Global Database on Blood Safety (GDBS) helps to monitor the status of adequate and safe blood availability, its presence alone does not serve as a solution to existing challenges. The objective of this evaluation was to determine the GDBS usefulness in improving the availability of adequate safe blood and its ability to function as a surveillance system. METHODS: The GDBS was evaluated using methods set out by the Centers for Disease Control and Prevention (CDC) Guidelines for assessing surveillance systems. Six recommended tasks were used to evaluate if the GDBS met the requirements of a surveillance system in a public health context. RESULTS: The majority of stakeholders engaged with GDBS found it was unique and useful. The GDBS answered all six questions essential for determining a blood safety surveillance system's usefulness. The GDBS fully met the needs to six of the eleven attributes used for evaluating the usefulness of a surveillance system. CONCLUSION: The GDBS is a unique global activity that provides vital data on safety of blood transfusion services across countries and regions. However, aspects of the GDBS such as timeliness of reporting and improvement of WHO Member States national blood information systems could enhance its effectiveness and potential to serve as a global surveillance system for blood safety. |
| Trends and gaps in national blood transfusion services - 14 sub-Saharan African countries, 2014-2016
Kanagasabai U , Chevalier MS , Drammeh B , Mili FD , Qualls ML , Bock N , Benech I , Nelson LJ , Alemnji G , Watts DH , Kimani D , Selenic D . MMWR Morb Mortal Wkly Rep 2018 67 (50) 1392-1396 Ensuring availability of safe blood products through recruitment of voluntary, nonremunerated, blood donors (VNRDs) and prevention of transfusion-transmissible infections (TTIs), including human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV), and syphilis, is important for public health (1,2). During 2004-2016, the U.S. President's Emergency Plan for AIDS Relief (PEPFAR) provided approximately $468 million in financial support and technical assistance* to 14 sub-Saharan African countries(dagger) with high HIV prevalence to strengthen national blood transfusion services (NBTSs)( section sign) and improve blood safety and availability. CDC analyzed these countries' 2014-2016 blood safety surveillance data to update previous reports (1,2) and summarize achievements and programmatic gaps as some NBTSs begin to transition funding and technical support from PEPFAR to local ministries of health (MOHs) (2,3). Despite a 60% increase in blood supply since 2004 and steady declines in HIV prevalence (to <1% among blood donors in seven of the 14 countries), HIV prevalence among blood donors still remains higher than that recommended by the World Health Organization (WHO) (4). PEPFAR support has contributed to significant reductions in HIV prevalence among blood donors in the majority of PEPFAR-supported countries, and linking donors who screen HIV-positive to confirmatory testing and indicated treatment, as well as further reducing TTIs, remains a public health priority (5). |
