Transmission Of Syphilis Research Articles

INCIDÊNCIA DE SÍFILIS NA POPULAÇÃO CARCERÁRIA MASCULINA ENTRE OS ANOS DE 2000 À 2024: UM ESTUDO DE REVISÃO INTEGRATIVA DA LITERATURA

This study analyzed the incidence of syphilis among the male prison population in Brazil from 2000 to 2024. It emphasizes that syphilis, caused by Treponema pallidum, is a Sexually Transmitted Infection (STI) with high prevalence in this vulnerable group, primarily due to poor hygiene conditions and limited access to healthcare services. An integrative literature review was conducted, including eight articles that met the inclusion criteria of studies published between 2000 and 2024 specifically addressing syphilis in the male prison population. Articles focusing on other STIs without direct relevance and studies with inadequate methodologies were excluded. The search was performed in the databases PubMed, BVS, MedLine, and Scielo, using descriptors such as “syphilis,” “prison population,” and “Sexually Transmitted Infections (STIs).” The findings indicate a high incidence of syphilis, exacerbated by risk practices such as unprotected sex and the sharing of syringes, along with the absence of adequate health policies. The study highlights the urgent need for effective interventions, including systematic screening and health education, to control the spread of the disease and improve the quality of life for inmates. These measures are essential not only for the health of prisoners but also for preventing the transmission of syphilis to the broader population.

Analysis of 2019 Ohio Disease Intervention Specialist (DIS) Records for Syphilis Cases Using Clustering Algorithms.

Developments in natural language processing (NLP) and unsupervised machine learning methodologies (e.g., clustering) have given researchers new tools to analyze both structured and unstructured health data. We applied these methods to 2019 Ohio disease intervention specialist (DIS) syphilis records, to determine whether these methods can uncover novel patterns of co-occurrence of individual characteristics, risk factors, and clinical characteristics of syphilis that are not yet reported in the literature. The 2019 DIS syphilis records (n=1,996) contain both structured data (categorical and numerical variables) and unstructured notes. In the structured data, we examined case demographics, syphilis risk factors, and clinical characteristics of syphilis. For the unstructured text, we applied TF-IDF (term frequency multiplied by inverse document frequency) weights, a common way to convert text into numerical representations. We performed agglomerative clustering with cosine similarity using the CLUTO software. The cluster analysis yielded six clusters of syphilis cases based on patterns in the structured and unstructured data. The average internal similarities were much higher than the average external similarities, indicating that the clusters were well-formed. The factors underlying three of the clusters related to patterns of missing data. The factors underlying the other three clusters were sexual behaviors and partnerships. Notably, one of the three consisted of individuals who reported oral sex with male or anonymous partners while intoxicated, and one was comprised mainly of males who have sex with females. Our analysis resulted in clusters that were well-formed mathematically, but did not reveal novel epidemiological information about syphilis risk factors or transmission that were not already known.

Syphilis testing, incidence, and reinfection among gay and bisexual men in Australia over a decade spanning HIV PrEP implementation: an analysis of surveillance data from 2012 to 2022

Gay and bisexual men (GBM) remain overrepresented among syphilis diagnoses in Australia and globally. The extent to which changes in sexual networks associated with HIV pre-exposure prophylaxis (PrEP) and treatment as prevention (TasP) may have influenced syphilis transmission among GBM at the population-level is poorly understood. We describe trends in syphilis testing and incidence among GBM in Australia over eleven years spanning widespread uptake of HIV PrEP and TasP. We analysed linked clinical data from GBM aged 16 years or older across a sentinel surveillance network in Australia from January 1, 2012, to December 31, 2022. Individuals with at least two clinic visits and with at least two syphilis tests during the observations period were included in testing and incidence analyses, respectively. Annual rates of testing and infectious syphilis incidence from 2012 to 2022 were disaggregated by HIV status and PrEP use (record of PrEP prescription; retrospectively categorised as ever or never-PrEP user). Cox regression explored associations between demographics, PrEP use and history of bacterial sexually transmissible infections (STIs) and infectious syphilis diagnosis. Among 129,278 GBM (mean age, 34.6 years [SD, 12.2]) included in testing rate analyses, 7.4% were living with HIV at entry and 31.1% were prescribed PrEP at least once during the study period. Overall syphilis testing rate was 114.0/100 person-years (py) and highest among GBM with HIV (168.4/100 py). Syphilis testing increased from 72.8/100 py to 151.8/100 py; driven largely by increases among ever-PrEP users. Among 94,710 GBM included in incidence analyses, there were 14,710 syphilis infections diagnosed over 451,560 person-years (incidence rate=3.3/100 py). Syphilis incidence was highest among GBM with HIV (6.5/100 py), followed by ever-PrEP users (3.5/100 py) and never-PrEP users (1.4/100 py). From 2012 to 2022, syphilis incidence increased among ever-PrEP users from 1.3/100 py to 5.1/100 py, and fluctuated between 5.4/100 py and 6.6/100 py among GBM with HIV. In multivariable Cox regression, previous syphilis diagnosis (adjusted hazard ratio [aHR]=1.98, 95% CI=1.83-2.14), living with HIV (aHR=1.83, 95% CI=1.12-1.25) and recent (past 12m) prescription of PrEP (aHR=1.78, 95% CI=1.61-1.97) were associated with syphilis diagnosis. Syphilis trends between GBM with HIV and GBM with evidence of PrEP use have converged over the past decade in Australia. Our findings recommend targeting emergent syphilis control strategies (e.g. doxycycline post-exposure prophylaxis) to GBM with prior syphilis diagnoses, using HIV PrEP or who are living with HIV.

Patient perspective on the elimination mother-to-child transmission of HIV, syphilis, and hepatitis B in Bali, Indonesia: a qualitative study

BackgroundThis study aimed to explore the facilitators and barriers to the elimination of human immunodeficiency virus (HIV), syphilis, and hepatitis B transmission based on the perspectives of mothers living with HIV, syphilis, and hepatitis B.MethodsThis study employed a descriptive, qualitative design. Semi-structured interviews were conducted with mothers living with HIV, syphilis, and/or hepatitis B virus. A total of 25 participants were included in the study. This study used a triangulation method conducted by members to enhance the validity and dependability of the findings. The study was conducted at referral hospitals and community health centers between September 2022 and February 2023. Data analysis utilized deductive content analysis and categorized themes based on a socio-ecological framework.ResultsThe findings revealed facilitators and barriers across five levels of the socio-ecological framework and 21 subcategories. The findings included the following: (1) At the policy level, facilitators were mandatory testing programs, and barriers were separating testing services from antenatal care facilities. (2) At the community level, facilitators included the involvement of non-governmental organizations (NGOs) and cross-sector support. Barriers included challenges faced by non-residents and fear of stigma and discrimination. (3) At the healthcare system level, facilitators included tracking and follow-up by midwives, positive relationships with healthcare providers, and satisfaction with healthcare services. Barriers included prolonged waiting times, insufficient information from healthcare providers, and administrative limitations. (4) At the interpersonal level, facilitators included partner and family support, open communication, and absence of stigma. Barriers included the reluctance of sexual partners to undergo screening. (5) At the individual level, facilitators included the desire for a healthy baby, adequate knowledge, self-acceptance, and commitment to a healthy lifestyle; barriers included the lack of administrative discipline.ConclusionMothers living with HIV, syphilis, or hepatitis B require tailored healthcare approaches. Healthcare professionals must understand and meet the needs of mothers within a comprehensive care continuum. The findings of this study advocate for the development and implementation of integrated care models that are responsive to the specific challenges and preferences of affected mothers, aiming to improve health outcomes for both mothers and their children.

Syphilis Positivity Among Men Who Have Sex With Men With Direct, Indirect, and No Linkage to Female Sex Partners: Exploring the Potential for Sex Network Bridging in Baltimore City, MD.

Syphilis epidemics among women and men who have sex with men (MSM) may be connected, but these connections are poorly understood. Using egocentric network data from a US urban MSM cohort, we examined sociodemographics, behaviors, and syphilis positivity among MSM with (1) direct (MSM who report sex with women, MSMW); (2) indirect (MSM who only report male partners, some of whom are MSMW, MSMO/W); and (3) no (MSM who only report male partners and whose partners only have sex with men, MSMO/O) connection to women. Sexually active MSM aged 18 to 45 years were administered behavioral and network interviews (recall period: 3 months) and syphilis/HIV testing. Syphilis positivity was defined as rapid plasma reagin titer ≥1:8. Modified Poisson regression was used to test for differences across groups. Among 385 MSM, 14.5% were MSMW and 22.3% were MSMO/W. MSMW and MSMO/W were significantly more likely than MSMO/O to report sex behaviors associated with increased syphilis acquisition/transmission risk, including ≥2 sex partners (MSMW: adjusted prevalence ratio [aPR], 1.28 [0.98-1.68]; MSMO/W: aPR, 1.35 [1.09-1.69]) and concurrent sex partners (MSMW: aPR, 1.50 [1.17-1.92]; MSMO/W: aPR, 1.39 [1.11-1.74]), and for MSMW only, transactional sex (aPR, 2.07 [1.11-3.88]). Syphilis positivity was 16.4% and was lower among MSMW (9.4%) and MSMO/W (14.1%) than MSMO/O (18.5%), but differences were not significant. There may be considerable connectivity between MSM and female sex partners that could facilitate syphilis transmission, and behaviors that increase acquisition/transmission risk among MSMW and MSMO/W may be distinct from MSMO/O. Future work should focus on examining the context and temporal patterns of sex partnerships among MSMW and MSMO/W.

Syfillis cases in Southeast Asia in 2015 amounted to 3 million. The areas that have the highest rates of syphilis transmission are Sub-Saharan Africa, the United States and Southeast Asia. Studies conducted in Africa show that there are 30% positive antenatal syphilis cases and 50% result in infant death in congenital syphilis. This research is a type of quantitative research with an analytical observational research design with a cross sectional study approach. The population in this study were all prospective brides and grooms in Keritang District, the working area of the Kotabaru Community Health Center in 2023, as of January, as many as 36 people who had bridal injections (catin) at the Community Health Center. The sampling technique used in the research was accidental sampling. Data was collected using a questionnaire and data processing using the SPSS program. Data analysis in this study was univariate and bivariate analysis using the chi-square test formula with a confidence level of 95% (0.05). The results of the study revealed that the level of knowledge of the prospective bride and groom (catin), the attitude of the prospective bride and groom (catin) and the support of health workers had a value of each variable less than 0.05 or a significance value of p<0.05, which indicated that there was a significant relationship of these three variables in prospective brides (catin) regarding syphilis in the working area of the Kotabaru health center, Keritang District, Inhil Regency, Riau in 2023.

Congenital Syphilis: A Re-Emerging but Preventable Infection.

Congenital syphilis presents a significant global burden, contributing to fetal loss, stillbirth, neonatal mortality, and congenital infection. Despite the target established in 2007 by the World Health Organization (WHO) of fewer than 50 cases per 100,000 live births, the global incidence is on the rise, particularly in low- and middle-income regions. Recent data indicate a rate of 473 cases per 100,000 live births, resulting in 661,000 total cases of congenital syphilis, including 355,000 adverse birth outcomes such as early fetal deaths, stillbirths, neonatal deaths, preterm or low-birth-weight births, and infants with clinical congenital syphilis. Alarmingly, only 6% of these adverse outcomes occurred in mothers who were enrolled, screened, and treated. Unlike many neonatal infections, congenital syphilis is preventable through effective antenatal screening and treatment of infected pregnant women. However, despite available screening tools, affordable treatment options, and the integration of prevention programs into antenatal care in various countries, congenital syphilis remains a pressing public health concern worldwide. This review aims to summarize the current epidemiology, transmission, and treatment of syphilis in pregnancy, as well as to explore global efforts to reduce vertical transmission and address the reasons for falling short of the WHO elimination target.

Analysis of Maternal and Congenital Syphilis Rates at a New Jersey University Hospital.

Syphilis and congenital syphilis (CS) cases have been rising in the U.S. and internationally since the 2000s. Social factors have been shown to increase the risk of CS transmission. The COVID-19 pandemic may have contributed to increased syphilis transmission. We aimed to quantify the rise in congenital syphilis (CS) rates at a large urban hospital and the impact of the COVID-19 pandemic on CS rates. We completed a retrospective chart review of 61 pregnant women with a positive test or previous diagnosis of syphilis at an urban academic hospital between 1 January 2016 and 1 June 2022. Maternal syphilis and CS rates increased over the 5 years (p < 0.001), particularly pre- and post-COVID-19 (p < 0.001). Of the mothers studied, 34.6% received adequate prenatal care, 62.7% received adequate screening, and 81.3% received adequate treatment. Stillbirth was noted in 6.6% of pregnancies. Of liveborn infants, 97.6% received appropriate treatment, and 45.1% received adequate follow-up. CS development was significantly associated with homelessness (p = 0.028) and past opioid use (p = 0.031). We concluded that maternal syphilis and CS rates have increased at our hospital, particularly during the COVID-19 pandemic. Access to prenatal care and timely maternal treatment are target areas for improvement.

Epidemiological analysis of the current prevalence of hepatitis B virus infection among pregnant and postpartum women in China from 2021 to 2023

Objective: To analyze hepatitis B serologic tests and the current prevalence of hepatitis B virus (HBV) infection among pregnant and postpartum women in China from 2021 to 2023. Methods: Data on managing the prevention of mother-to-child transmission of HIV, syphilis, and hepatitis were retrieved from the National Information System. A positive serum HBsAg test was used to define HBV infection. The χ(2) test was used to compare the coverage rate of the hepatitis B serologic test across different years, in early-stage pregnancy, and the current HBV infection in pregnant and postpartum women. A two-sided P value of <0.05 was considered a statistically significant difference. Results: The coverage rate for hepatitis B serological detection in pregnant (including intrapartum) and postpartum women and early-stage pregnancy rose from 99.68% (10 463 059/10 496 883) and 82.96% (8 707 765/10 496 883) to 99.94% (8 678 777/8 684 387, P < 0.001) and 88.87% (7 717 857/8 684 387, P < 0.001) in China between 2021 and 2023. The current prevalence rate of HBV infection decreased from 4.98% (521 479/10 463 059) in 2021 to 4.56% (396 148/8 678 777) in 2023 among pregnant and postpartum women (P < 0.001). The current prevalence rate of HBV infection ranged from 1.53% to 10.39% among pregnant and postpartum women in various provinces of China in 2023. Conclusion: The coverage rate for hepatitis B serologic tests in China increased significantly between 2021 and 2023 in pregnant and postpartum women. Therefore, the current prevalence rate of HBV infection has decreased significantly in pregnant and postpartum women, but a regional difference still exists.

Assessing Syphilis transmission among MSM population incorporating low and high-risk infection: a modeling study

Assessing Syphilis transmission among MSM population incorporating low and high-risk infection: a modeling study

Syphilis and Beyond: A Comprehensive Analysis of Associated Infections and Comorbidities in a Five-Year Retrospective Study in the United Arab Emirates (2018-2022)

Objectives This study explores the clinical characteristics, associated infections, and management outcomes of syphilis within a specific population over the years 2018 to 2022. With a focus on the frequency, clinical manifestations, and co-infections of syphilis, the research addresses a critical gap in understanding the nuanced dynamics of this sexually transmitted infection and its impact on public health. Methods The study employs a retrospective analysis of data collected from 2018 to 2022, utilizing three key serological tests (Syphilis AB, RPR/VDRL, and TPHA) to characterize syphilis infections within the population. Clinical manifestations and associated infections, including HIV, HBV, HCV, Chlamydia, Gonorrhea, and HPV, are systematically assessed. Treatment rates and re-infection patterns are also analyzed, providing a comprehensive overview of syphilis epidemiology within the studied timeframe. Results The frequency of syphilis, particularly indicated by the Syphilis AB test, exhibited a marked increase in 2020, reaching 96%, suggesting a heightened frequency within the population. RPR/VDRL test results demonstrated consistent frequency, emphasizing the persistent presence of active syphilis infections. Clinical manifestations, such as chancre, skin rashes, alopecia syphilitica, and lymphadenopathy, displayed dynamic patterns over the study years. Co-infection rates varied, with fluctuations observed in HIV, Chlamydia, Gonorrhea, and HPV, while HBV and HCV showed infrequent but stable frequency. The management of syphilis cases demonstrated commendable treatment rates, but an increase in re-infection rates in 2021 highlights the need for continued vigilance. Conclusion This study provides a comprehensive evaluation of syphilis epidemiology, clinical characteristics, and associated infections within the studied population. The results offer valuable insights into the dynamic nature of syphilis and its co-infections, informing public health initiatives and interventions. The findings contribute to our understanding of the epidemiological landscape and underscore the importance of sustained efforts in both prevention and treatment to curb the transmission of syphilis and its associated infections. The study, however, calls for continued vigilance and research to address the evolving trends and challenges in syphilis management within the specified population.

Gaps in the prevention of mother-to-child transmission of syphilis: a review of reported cases, South Africa, January 2020-June 2022.

Congenital syphilis (CS) is preventable through timely antenatal care (ANC), syphilis screening and treatment among pregnant women. Robust CS surveillance can identify gaps in this prevention cascade. We reviewed CS cases reported to the South African notifiable medical conditions surveillance system (NMCSS) from January 2020 to June 2022. CS cases are reported using a case notification form (CNF) containing limited infant demographic and clinical characteristics. During January 2020-June 2022, healthcare workers supplemented CNFs with a case investigation form (CIF) containing maternal and infant testing and treatment information. We describe CS cases with/without a matching CIF and gaps in the CS prevention cascade among those with clinical information. During January 2020-June 2022, 938 CS cases were reported to the NMCSS with a median age of 1 day (interquartile range: 0-5). Nine percent were diagnosed based on clinical signs and symptoms only. During January 2020-June 2022, 667 CIFs were reported with 51% (343) successfully matched to a CNF. Only 57% of mothers of infants with a matching CIF had an ANC booking visit (entry into ANC). Overall, 87% of mothers were tested for syphilis increasing to 98% among mothers with an ANC booking visit. Median time between first syphilis test and delivery was 16 days overall increasing to 82 days among mothers with an ANC booking visit. Only 37% of CS cases had accompanying clinical information to support evaluation of the prevention cascade. Mothers with an ANC booking visit had increased syphilis screening and time before delivery to allow for adequate treatment.

Impact of screening and doxycycline prevention on the syphilis epidemic among men who have sex with men in British Columbia: a mathematical modelling study

Men who have sex with men (MSM) in British Columbia (BC) are disproportionately affected by infectious syphilis and HIV. In this study, we developed a co-interaction model and evaluated the impact and effectiveness of possible interventions among different MSM subgroups on the syphilis epidemic. We designed a deterministic compartmental model, which stratified MSM by HIV status and HIV pre-exposure prophylaxis (HIV-PrEP) usage into (1) HIV-negative/unaware MSM (HIV-PrEP not recommended, noton HIV-PrEP), (2) HIV-negative/unaware MSM with HIV-PrEP recommended (not on HIV-PrEP), (3)HIV-negative/unaware MSM actively on HIV-PrEP, and (4) MSM diagnosed with HIV. We estimated the effect of scaling up syphilis testing frequency from Status Quo to six-, four-, and three-months, increasing the percentage of MSM using doxycycline prevention (Doxy-P) to 25%, 50%, and 100% of the target level, and a combination of both among subgroups (2)-(4). We also assessed the impact of these interventions on the syphilis incidence rates from 2020 to 2034 in comparison to the Status Quo scenario where no intervention was introduced. Under the Status Quo scenario, with the expansion of the HIV-PrEP program to improve syphilis testing, the syphilis incidence rate was estimated to peak at 16.1 [Credible Interval (CI):14.2-17.9] per 1,000 person-years (PYs) in 2023 and decrease to 6.7 (CI:3.8-10.9) per 1,000 PYs by 2034. The syphilis incidence rate in 2034 was estimated at 0.7 (0.3-1.3) per 1,000 PYs if MSM diagnosed with HIV could be tested every four months, and at 1.5 (0.7-3.0) per 1,000 PYs if HIV-negative/unaware MSM actively on HIV-PrEP could be tested every three months. By achieving 100% of the target coverage of Doxy-P, the syphilis incidence rate was estimated at 1.4 (0.5-3.4) if focusing on MSM diagnosed with HIV, and 2.6 (1.2-5.1) per 1,000 PYs if focusing on HIV-negative/unaware MSM actively on HIV-PrEP. Under the combined interventions, the syphilis incidence rate could be as low as 0.0 (0.0-0.1) and 0.8 (0.3-1.8) per 1,000 PYs, respectively. The HIV-PrEP program in BC plays a crucial role in increasing syphilis testing frequency among high-risk MSM and reducing syphilis transmission among this group. In addition, introducing Doxy-P can be an effective complementary strategy to minimize syphilis incidence, especially among MSM diagnosed with HIV. This work was funded by the Canadian Institutes of Health Research.

Seroprevalence of Syphilis among Pregnant Women Attending Antenatal Care in Yaqshiid District, Mogadishu, Somalia

Background: The prevalence of syphilis among pregnant women in Somalia has been poorly studied, despite its significant impact on maternal and fetal health. In Somalia, the last syphilis study was conducted approximately 30 years ago, leaving a critical knowledge gap regarding the current epidemic of syphilis among pregnant women. Materials and methods: From January 2023 to April 2023, a hospital-based cross-sectional study was conducted on maternal and child health. A total of 300 pregnant women were included in the study, and the seroprevalence of syphilis was determined using the Venereal Disease Research Laboratory. This one-step quick diagnostic test cassette was used as the preliminary screening tool, and Positive results were confirmed using the full chemiluminescence immunoassay (CLIA) analyzer MAGLUMI. A structured questionnaire was used to collect demographic characteristics and knowledge regarding syphilis transmission and mother-to-child transmission. SPSS Version 27.0 was used to analyze the gathered data. Statistical significance was set at p &lt; 0.05. Results: Overall, 5.3% (16/300) of pregnant women had syphilis seroprevalence. Seroprevalence rates were higher in women aged 24-34 (50.0%). There were significant relationships between syphilis infection and education (p &lt; 0.000), occupation (p &lt; 0.000), and residence (p = 0.002). Furthermore, a significant majority of pregnant women (78%) were unaware of syphilis transmission routes and its correlation to HIV risk (81.7%). Stillbirths constituted 23.3% of pregnancy-related problems, whereas 17% of pregnant women had a prior record of blood transfusions. Conclusions: The study found an alarming syphilis seroprevalence in pregnant women, especially in certain demographic groups. The lack of knowledge of syphilis transmission and its effects highlights the necessity for targeted education. Improved prenatal care, health awareness, and effective prevention should lessen the effects of syphilis on mother and newborn health.

Development and validation of an individualised nomogram to predict mother-to-child transmission in pregnant women with syphilis in China: a retrospective cohort study

Challenges to integrating programs for the elimination of mother-to-child transmission of HIV, syphilis, and hepatitis B into antenatal care: Experiences from Indonesia.

The WHO's Asia-Pacific framework for triple elimination recommends that countries evaluate their programs for the elimination of mother-to-child transmission of HIV, syphilis, and hepatitis B (EMTCT), including identifying gaps to improve program planning and the implementation of elimination strategies in antenatal care (ANC) services. In 2022, the Indonesian Ministry of Health reported that only 39% of pregnant women were tested for HIV, 14% for syphilis, and 28% for hepatitis B, respectively. We conducted a qualitative study involving a focus group discussion (FGD) and in-depth interviews with 25 key stakeholders in Bali and West Nusa Tenggara Provinces to identify specific challenges to testing for HIV, syphilis, and hepatitis B in ANC settings. Thematic analysis was used to identify the themes generated from the data. Health system bottlenecks experienced by stakeholders included supply chain management issues involving stock forecasting and stock monitoring, stock-outs of rapid test reagents which were particularly most frequent and for longer durations for syphilis and hepatitis B, high staff turnover, lack of staff training on how to perform the test, the complexity and time needed to record the data on women's characteristics, risk behaviours, and testing in both paper format and into the computer-based surveillance systems, discrepancies in program coverage data from different divisions of the district health office involved in the reporting system, high levels of stigma that prevented women from being followed up, challenges in notifying partners, and inadequate reporting and referral of women from private providers to public ones for testing. Interventions addressing the above challenges are worthy of consideration to improve the health system function and integrate EMTCT into the ANC settings.

Incorporating an intersectional gender approach to improve access to maternal and child health screening services

BackgroundIn the Americas, the Pan American Health Organization (PAHO) has promoted initiatives that aim at the elimination of mother-to-child transmitted diseases for over two decades. Although Guatemala has assumed the commitment to improve access and coverage of reproductive and perinatal services, the goals have not yet been reached. Often, the implementation of these efforts is hampered by complexities rooted in social, cultural, and environmental intersections. The objective of this work is to share our experience applying gender intersectionality as a methodological and analytical tool in a participatory research project that aims to improve access to maternal and child health screening services. The study shows the novel strategy that incorporates intersectionality contributing to evidence on how it can be applied to strengthen public health efforts around the implementation of the EMTCT Plus (Elimination of mother-to-child transmission of HIV, Syphilis, Hepatitis B, and Chagas disease) framework, in the mostly rural municipality of Comapa, in Guatemala.MethodsWe applied a participatory methodology, integrating theoretical and methodological frameworks to have an intersectional understanding of health services delivered by both, midwives, and the public health institution, for the prevention, diagnosis, treatment, and follow-up of HIV, Syphilis, Hepatitis B, and Chagas. The data was collected by conducting interviews, focus groups, workshops, and reviewing laboratory databases, guided by five strategies from a cultural appropriateness framework.ResultsThe intersectional analysis shed light on the synergies and gaps of the current efforts and protocols implemented by both the midwives and the Ministry of Health. The services offered for the four diseases were often delivered independently from each other, and a comprehensive educational and communication material strategy was absent. However, our findings will be used to inform consistent, locally relevant, and culturally appropriate educational content for the local population, also following the national policy guidelines.ConclusionsUsing intersectionality as a method and as an analytical tool allowed us to understand the (1) interrelation of diverse social, cultural, and environmental determinants which influence the delivery of health services, as well as (2) the dynamics between the traditional and institutional health systems. (3) Community engagement and the participation of different stakeholders in a consultative process have been fundamental for the conceptual and methodological tenets of this research. (4) Finally, giving a more prominent role to midwives can strengthen sustainability and cultural appropriateness, which is complementary to the delivery of institutional health services.

Provider-Reported Barriers in Sexual Health Care Services for Women With Upstream Barriers: The Case of Syphilis and Congenital Syphilis in Southern Colorado, 2022.

Syphilis and congenital syphilis rates have increased sharply in Colorado in the past 5 years. Congenital syphilis is passed during pregnancy in utero and can cause lifelong physical, developmental, and neurologic problems for the child, or can lead to miscarriage, stillbirth, or early infant death. Congenital syphilis is easily prevented if the mother receives timely testing, treatment, and prenatal care. Providers can play a key role in preventing congenital syphilis for women with social vulnerabilities, who have a higher likelihood of syphilis and/or congenital syphilis infection. We surveyed 23 and interviewed 4 health care providers in southern Colorado in 2022 to record their experiences in providing sexual health care services. We asked providers with direct care experience about perceived barriers in effectively treating syphilis. The most significant barriers reported in the survey were the cost of treatment (26%) and the loss to follow-up (22%). Interviews revealed further challenges, including discretionary testing procedures, delays in screening results, treatment referral issues, and stigma around substance use and sexual activity. Elevated syphilis and congenital syphilis rates pose significant public health challenges. Coordinated interventions are necessary to effectively reduce the transmission of syphilis and congenital syphilis among women with upstream barriers. Potential care solutions include expanding rapid, point-of care testing and treatment options, supporting bicillin delivery or web-based inventory systems, offering anti-stigma training for providers, offering mental and behavioral health resources at providers' clinics, and expanding partnerships with syringe access programs.

Oman eliminates mother-to-child transmission of HIV and syphilis.

Oman eliminates mother-to-child transmission of HIV and syphilis.

The prevalence of gestational syphilis in Malawi between 2014 and 2022: spatiotemporal modeling of population-level factors.

Mother-to-child transmission of syphilis remains high especially in the WHO AFRO region with a prevalence of 1.62%, resulting in a congenital syphilis rate of 1,119 per 100,000 live births. Elimination efforts can be supported by an understanding of the spatial and temporal changes in disease over time, which can identify priority areas for targeted interventions aimed at reducing transmission. We collated routine surveillance data from health facilities and covariate data from demographic and health surveys conducted in Malawi between 2014 and 2022. We fitted a Bayesian hierarchical mixed model with spatial and temporally structured random effects to model the district-level monthly counts of maternal syphilis notifications as a function of individual- and district-level predictors. We then generated district-level spatiotemporally explicit risk profiles to estimate the effect of individual- and district-level covariates on maternal syphilis notifications and to identify hotspot areas. Overall, the national prevalence of maternal syphilis increased from 0.28% (95% CI: 0.27-0.29%) in 2014 to peaking in 2021 at 1.92% (95% CI: 1.89-1.96%). Between 2020 and 2022, there was a decline in prevalence, with the most significant decline seen in Zomba District (1.40, 95% CI: 1.12-1.66%). In regression models, a one percentage point increase in district-level antenatal HIV prevalence was associated with increased maternal syphilis (prevalence ratio [PR]: 1.15, 95% credible interval [CrI]: 1.10-1.21). There was also an increased prevalence of maternal syphilis associated with an increased district-level mean number of sex partners (PR: 1.05, 95% CrI: 0.80-1.37). The number of districts with a high prevalence of maternal syphilis also increased between 2014 and 2022, especially in the southern region, where most had a high probability (approaching 100%) of having high maternal syphilis (defined as relative risk >1 compared to the standard population of women aged 15-49 years) in 2022. Maternal syphilis prevalence in Malawi shows an increasing upward trend, with an estimated six times relative increase between 2014 and 2022 (0.28% to 1.73%) and strong associations with higher district-level HIV prevalence. Controlling syphilis depends on reaching vulnerable populations at the sub-national level, which may be disproportionately affected. Our findings support the move to integrate the elimination of mother-to-child transmission (EMTCT) of syphilis programs with existing prevention of mother-to-child transmission (PMTCT) of HIV programs.
