RESUMEN

BACKGROUND: Screening for tuberculosis (TB) and providing TB preventive treatment (TPT) along with antiretroviral therapy is key components of human immune deficiency virus (HIV) care. The uptake of TPT during the coronavirus disease 2019 (COVID-19) period has not been adequately assessed in Addis Ababa City Administration. This study aimed at assessing TPT uptake status among People living with HIV (PLHIV) newly initiated on antiretroviral therapy during the COVID-19 period at all public hospitals of Addis Ababa City Administration, Ethiopia. METHODS: A retrospective data review was conducted from April-July 2022. Routine District Health Information System 2 database was reviewed for the period from April 2020-March 2022. Proportion and mean with standard deviation were computed. Logistic regression analysis was conducted to assess factors associated with TPT completion. A p-value of < 0.05 was considered statistically significant. RESULTS: A total of 1,069 PLHIV, aged 18 years and above were newly initiated on antiretroviral therapy, and of these 1,059 (99.1%) underwent screening for TB symptoms. Nine hundred twelve (86.1%) were negative for TB symptoms. Overall, 78.8% (719) of cases who were negative for TB symptoms were initiated on TPT, and of these 70.5% and 22.8% were completed and discontinued TPT, respectively. Of 719 cases who were initiated on TPT, 334 (46.5%) and 385 (53.5%) were initiated on isoniazid plus rifapentine weekly for three months and Isoniazid preventive therapy daily for six months, respectively. PLHIV who were initiated on isoniazid plus rifapentine weekly for three months were more likely to complete TPT (adjusted odds ratio [AOR],1.68; 95% confidence interval [CI], 1.01, 2.79) compared to those who were initiated on Isoniazid preventive therapy daily for six months. CONCLUSION: While the proportion of PLHIV screened for TB was high, TPT uptake was low and far below the national target of achieving 90% TPT coverage. Overall a considerable proportion of cases discontinued TPT in this study. Further strengthening of the programmatic management of latent TB infection among PLHIV is needed. Therefore, efforts should be made by the Addis Ababa City Administration Health Bureau authorities and program managers to strengthen the initiation and completion of TPT among PLHIV in public hospitals.

RESUMEN

BACKGROUND: Tuberculosis (TB) remains a pressing public health issue, posing a significant threat to individuals' well-being and lives. This study delves into the TB incidence in Chinese mainland during 2014-2021, aiming to gain deeper insights into their epidemiological characteristics and explore macro-level factors to enhance control and prevention. METHODS: TB incidence data in Chinese mainland from 2014 to 2021 were sourced from the National Notifiable Disease Reporting System (NNDRS). A two-stage distributed lag nonlinear model (DLNM) was constructed to evaluate the lag and non-linearity of daily average temperature (℃, Atemp), average relative humidity (%, ARH), average wind speed (m/s, AWS), sunshine duration (h, SD) and precipitation (mm, PRE) on the TB incidence. A spatial panel data model was used to assess the impact of demographic, medical and health resource, and economic factors on TB incidence. RESULTS: A total of 6,587,439 TB cases were reported in Chinese mainland during 2014-2021, with an average annual incidence rate of 59.17/100,000. The TB incidence decreased from 67.05/100,000 in 2014 to 46.40/100,000 in 2021, notably declining from 2018 to 2021 (APC = -8.87%, 95% CI: -11.97, -6.85%). TB incidence rates were higher among males, farmers, and individuals aged 65 years and older. Spatiotemporal analysis revealed a significant cluster in Xinjiang, Qinghai, and Xizang from March 2017 to June 2019 (RR = 3.94, P < 0.001). From 2014 to 2021, the proportion of etiologically confirmed cases increased from 31.31% to 56.98%, and the time interval from TB onset to diagnosis shortened from 26 days (IQR: 10-56 days) to 19 days (IQR: 7-44 days). Specific meteorological conditions, including low temperature (< 16.69℃), high relative humidity (> 71.73%), low sunshine duration (< 6.18 h) increased the risk of TB incidence, while extreme low wind speed (< 2.79 m/s) decreased the risk. The spatial Durbin model showed positive associations between TB incidence rates and sex ratio (ß = 1.98), number of beds in medical and health institutions per 10,000 population (ß = 0.90), and total health expenses (ß = 0.55). There were negative associations between TB incidence rates and population (ß = -1.14), population density (ß = -0.19), urbanization rate (ß = -0.62), number of medical and health institutions (ß = -0.23), and number of health technicians per 10,000 population (ß = -0.70). CONCLUSIONS: Significant progress has been made in TB control and prevention in China, but challenges persist among some populations and areas. Varied relationships were observed between TB incidence and factors from meteorological, demographic, medical and health resource, and economic aspects. These findings underscore the importance of ongoing efforts to strengthen TB control and implement digital/intelligent surveillance for early risk detection and comprehensive interventions.

RESUMEN

OBJECTIVES: This qualitative study aimed to explore opportunities to strengthen tuberculosis (TB) health service delivery from the perspectives of health workers providing TB care in Shigatse prefecture of Tibet Autonomous Region, China. DESIGN: Qualitative research, semi-structured in-depth interviews. SETTING: The TB care ecosystem in Shigatse, including primary and community care. PARTICIPANTS: Participants: 37 semi-structured interviews were conducted with village doctors (14), township doctors and nurses (14), county hospital doctors (7) and Shigatse Centre for Disease Control staff (2). RESULTS: The three main themes reported include (1) the importance of training primary and community health workers to identify people with symptoms of TB, ensure TB is diagnosed and link people with TB to further care; (2) the need to engage community health workers to ensure retention in care and adherence to TB medications; and (3) the opportunity for innovative technologies to support coordinated care, retention in care and adherence to medication in Shigatse. CONCLUSIONS: The quality of TB care could be improved across the care cascade in Tibet and other high-burden, remote settings by strengthening primary care through ongoing training, greater support and inclusion of community health workers and by leveraging technology to create a circle of care. Future formative and implementation research should include the perspectives of health workers at all levels to improve care organisation and delivery.

RESUMEN

Tuberculosis (TB) a disease caused by Mycobacterium tuberculosis (Mtb) poses a significant threat to human life, and current BCG vaccinations only provide sporadic protection, therefore there is a need for developing efficient vaccines. Numerous immunoinformatic methods have been utilized previously, here for the first time a deep learning framework based on Deconvolutional Neural Networks (DCNN) and Bidirectional Long Short-Term Memory (DCNN-BiLSTM) was used to predict Mtb Multiepitope vaccine (MtbMEV) subunits against six Mtb H37Rv proteins. The trained model was used to design MEV within a few minutes against TB better than other machine learning models with 99.5% accuracy. The MEV has good antigenicity, and physiochemical properties, and is thermostable, soluble, and hydrophilic. The vaccine's BLAST search ruled out the possibility of autoimmune reactions. The secondary structure analysis revealed 87% coil, 10% beta, and 2% alpha helix, while the tertiary structure was highly upgraded after refinement. Molecular docking with TLR3 and TLR4 receptors showed good binding, indicating high immune reactions. Immune response simulation confirmed the generation of innate and adaptive responses. In-silico cloning revealed the vaccine is highly expressed in E. coli. The results can be further experimentally verified using various analyses to establish a candidate vaccine for future clinical trials.

RESUMEN

Brazil was heavily affected by COVID-19 both with death toll and economically, with absence of a centralized Federal Government response. Tuberculosis (TB) notifications decreased in 2020 but partial recovery was observed in 2021. We have previously shown a sharp (93%) reduction in TB preventive treatment notifications among five Brazilian cities with more than 1,000 notifications in 2021. We hypothesized TB preventive treatment would also recover. We updated the previous analysis by adding other cities that hold more than a 1,000 notifications until 2022. Data aggregated by 2-week periods were extracted from the Information System for Notifying People Undergoing Treatment for LTBI (IL-TB). Biweekly percentage change (BPC) of notifications until October 2022 and outcomes until July 2022 (in the two weeks of TB preventive treatment initiation) were analyzed using Joinpoint software. A total of 39,701 notifications in 11 cities were included, 66% from São Paulo and Rio de Janeiro, Brazil. We found a significant increase of TB preventive treatment notifications in the beginning of 2021 (BPC range 1.4-49.6), with sustained progression in seven out of the 11 cities. Overall, median completion rates were 65%. In most cities, a gradual and steady decrease of treatment completion rates was found, except for Rio de Janeiro and Manaus (Amazonas State, Brazil), where a BPC of 1.5 and 1.2, respectively, was followed by a sustained increase. Notifications and completion proportions of TB preventive treatment were heterogeneous, which partly reflects the heterogeneity in local response to the pandemic. We found that notifications were recovered, and that the sharp 2021 decrease was no longer observed, which suggests delays in notification. In conclusion, the sharp reductions in TB preventive treatment completion rates in most cities might have been caused by delays in reporting; however, the sustained and progressive decrease are a concern.

RESUMEN

BACKGROUND: Tuberculosis (TB) remains a public health concern in Kenya despite the massive global efforts towards ending TB. The impediments to TB prevention and care efforts include poor health systems, resource limitations and other sociopolitical contexts that inform policy and implementation. Notably, TB cases are much higher in men than women. Therefore, the political economy analysis (PEA) study provides in-depth contexts and understanding of the gender gaps to access and successful treatment for TB infection. DESIGN: PEA adopts a qualitative, in-depth approach through key informant interviews (KII) and documentary analysis. SETTING AND PARTICIPANTS: The KIIs were distributed among government entities, academia, non-state actors and community TB groups from Kenya. RESULTS: The themes identified were mapped onto the applied PEA analysis framework domains. The contextual and institutional issues included gender concerns related to the disconnect between TB policies and gender inclusion aspects, such as low prioritisation for TB programmes, limited use of evidence to inform decisions and poor health system structures. The broad barriers influencing the social contexts for TB programmes were social stigma and cultural norms such as traditional interventions that negatively impact health-seeking behaviours. The themes around the economic situation were poverty and unemployment, food insecurity and malnutrition. The political context centred around the systemic and governance gaps in the health system from the national and devolved health functions. CONCLUSION: Broad contextual factors identified from the PEA widen the disparity in targeted gender efforts toward men. Following the development of effective TB policies and strategies, it is essential to have well-planned gendered responsive interventions with a clear implementation plan and monitoring system to enhance access to TB prevention and care.

RESUMEN

The large COVID-19 outbreaks in prisons in the Washington (USA) State Department of Corrections (WADOC) system during 2020 highlighted the need for a new public health approach to prevent and control COVID-19 transmission in the system's 12 facilities. WADOC and the Washington State Department of Health (WADOH) responded by strengthening partnerships through dedicated corrections-focused public health staff, improving cross-agency outbreak response coordination, implementing and developing corrections-specific public health guidance, and establishing collaborative data systems. The preexisting partnerships and trust between WADOC and WADOH, strengthened during the COVID-19 response, laid the foundation for a collaborative response during late 2021 to the largest tuberculosis outbreak in Washington State in the past 20 years. We describe challenges of a multiagency collaboration during 2 outbreak responses, as well as approaches to address those challenges, and share lessons learned for future communicable disease outbreak responses in correctional settings.

RESUMEN

As a chronic infectious disease, tuberculosis (TB) is closely related to immune regulation and immune effect. Immunotherapy which can improve the curative effect of tuberculosis and control the spread of tuberculosis, is one of the important means for the comprehensive treatment of tuberculosis. From October 2022 to September 2023, research on the immunotherapy of tuberculosis at home and abroad continues to increase, providing new opportunities for the treatment of multidrug-resistant and extensively drug-resistant tuberculosis. Host-targeted therapy and therapeutic vaccines are new directions for research into TB adjuvant therapy.

RESUMEN

There are limitations to traditional treatment approaches in addressing the needs of individuals with dual comorbidity of TB and SUD. The concept of harm reduction as a distinct approach to addressing substance use, focusing on minimising the negative consequences associated with it rather than advocating for complete abstinence. Different harm reduction strategies, such as opioid substitution therapy, needle and syringe programmes, testing for viral infections etc. have been effectively employed for SUDs in past. Similarly, TB risk minimization approaches like improving housing and nutrition and focused testing strategies are considered as harm reduction strategies for TB management. The relationship between tuberculosis (TB) and substance use disorders (SUDs) involves a complex interplay of biopsychosocial factors. It is crucial to prioritise integrated and closely monitored care in order to address the treatment challenges and potential drug interactions that may arise. In light of the acknowledged challenges like limited awareness, infrastructure, drug resistance, and stigma, it is imperative to explore potential avenues for the implementation of harm reduction strategies targeting individuals with comorbid TB and SUD in India. Potential strategies for addressing the issue includes a range of measures, such as augmenting investments in healthcare, integrating policies, tackling social determinants, and establishing shared platforms for psychosocial rehabilitation.

RESUMEN

Tuberculosis continues to be the leading cause of death worldwide. India shares twenty five percent of total tuberculosis population. Programmatic approach to fight against tuberculosis started in this country in the form of National Tuberculosis Program (NTP). In due course of time India adopted many strategic changes in its fight against tuberculosis. The current program named National tuberculosis elimination program (NTEP) has been set up to eliminate TB by 2025. There are some challenges which India need to overcome to achieve its target five years ahead of the sustainable development goals. Insufficient budget, inadequate diagnostic facilities, under-reporting, low success rate, high dropout rate, social stigma are some of the major challenges in the path to achieve a TB elimination status. Besides that, all the backlogs demand for swift performance in identification, notification, and treatment of TB cases. India has all the potential to eliminate tuberculosis. Strengthening of health system, mainstreaming of private sectors, enhancing diagnostic facilities, inclusion of latest diagnostic techniques, addressing social hindrances, and advocacy for higher budget are some of the program strengthening measures, if followed properly, can take India towards a TB free status.

RESUMEN

INTRODUCTION: The overall incidence of tuberculosis (TB) in France is low; thus, BCG vaccination is no longer mandatory. In French Guiana - a French overseas territory - BCG vaccination is strongly recommended because the incidence of TB is high in the context of mass immigration from endemic countries with low BCG vaccination rates. Thus, it is important to assess Bacillus Calmette-Guérin (BCG) vaccination coverage and its predictors. METHODS: We used data from the 2014 French Guiana Yellow Fever survey, which was conducted by the Observatoire Régional de la Santé de Guyane. Demographic and immunization data from eligible children and their families were collected using a questionnaire. Children who had an immunization card and who were no older than 7 years of age at the time of the survey were eligible. The Coverage for BCG and other mandatory vaccines were estimated; the delay in BCG vaccination was also computed. Univariate and multivariate analyses identified predictors associated with BCG immunization and BCG delayed immunization (after 2 months of age). RESULTS AND CONCLUSION: Overall, 469 children were eligible for this study. The total BCG coverage was 79.5 %, and the proportion of children vaccinated with delay was 50.7 %. The multivariate analysis indicated that BCVA was significantly greater among children younger than 3 years of age, whose household head was employed and whose education level was greater. None of the predictors were associated with the delay of BCG vaccination.

RESUMEN

INTRODUCTION: The purpose of this study is to assess the levels of knowledge, attitude, and practice (KAP) related to TB, and to analyze the differences among various demographic groups. METHODOLOGY: A total of 621 students enrolled in Qingdao High School, coming from high TB burden settings. The cross-sectional study was conducted from May to July of 2022. Participants completed an online questionnaire. Differences in knowledge and practice based on participant characteristics were analyzed using the Wilcoxon rank test and Kruskal-Wallis rank test. Group differences were assessed using a rank-based analysis of variance. RESULTS: The mean percentage of correct answers for TB knowledge and practice was 82.09% and 83.25%, respectively. Grade Three students showed higher knowledge and practice scores than Grade One or Grade Two students (t = -3.9935, p = 0.0002, t = 3.4537, p = 0.0018. 8.58 vs 7.94, 8.58 vs 8.23. t = 3.4562, p = 0.0018, t = -2.8688, p = 0.0128. 1.78 vs 1.61, 1.78 vs 1.64). A significant majority (78.42%) of students expressed fear of being affected by TB. 49.28% of the students would support and help TB patients. 88.08% of participants had heard of TB, with 72.94% learning about it at school, mainly through visual aids like posters. Information was predominantly obtained from online sources (websites, microblogs, WeChat, etc.). CONCLUSIONS: It is recommended to develop a TB curriculum for lower-grade students to enhance awareness of TB prevention through various means, including the internet and social media.

RESUMEN

The study reveals main methodological approaches in monitoring and evaluating role of socially significant infectious diseases in reducing quality of public health in the Russian Federation. The article proposes at population level the grouping of main risk factors affecting quality of public health, exemplified by epidemiology of tuberculosis. The purpose of the study is to develop methodology of exploration of impact of socially significant infections on decreasing of quality of public health exemplified by epidemiology of tuberculosis as infectious disease that is well studied in medical social aspects and having fully functioning TB control and high level monitoring system. The informational analytical methodology was applied conjointly with critical analysis of national and foreign publications, normative legal acts, selected through scientific search systems PubMed, Medline, www.base-search.net, www.refseek.com, E-library, CiberLeninka, "Garant" and "ConsultantPlus". The depth of search was limited by 15 years and more. The data from the federal statistical observation form No. 8 "Information about diseases with active tuberculosis" for 2021 was also evaluated. For the first time, the grouping of main risk factors of socially significant infections , affecting decrease of quality of public health at population level are proposed. The mentioned factors are grouped as epidemiological; social economic (including economic damage caused directly by tuberculosis); demographic; behavioral; biomedical (presence of diseases not associated with tuberculosis, but reducing immunity); climatic geographical, etc. The further analysis and listing of specific indicators of each group of factors is required in order to monitor and quickly assess impact of socially significant infectious diseases on public health in the Russian Federation and its Subjects. The analysis of scientific literature demonstrated that, despite breadth of studying tuberculosis risk factors, they are non-systematized and fragmented. The methodological approaches to studying impact of socially significant infectious diseases on public health in foreign countries and in the Russian Federation, are practically absent. The compilation and actualization of listing of indicative indicators for each group of factors with the choice of statistical methods of their calculation, evaluation and interpretation will permit to develop methodological approaches to monitoring and assessing role of tuberculosis (hereinafter - HIV infection, parenteral viral hepatitis, etc.) in altering quality of public health in the Russian Federation with development of rapidly updated database of selected indicators at the level of each Subject of the Russian Federation.

RESUMEN

Diagnostic delay for TB infected individuals and the lack of TB vaccines for adults are the main challenges to achieve the goals of WHO by 2050. In order to evaluate the impacts of diagnostic delay and vaccination for adults on prevalence of TB, we propose an age-structured model with latent age and infection age, and we incorporate Mycobacterium TB in the environment and vaccination into the model. Diagnostic delay is indicated by the age of infection before receiving treatment. The threshold dynamics are established in terms of the basic reproduction number R 0 . When R 0 < 1 , the disease-free equilibrium is globally asymptotically stable, which means that TB epidemic will die out; When R 0 = 1 , the disease-free equilibrium is globally attractive; there exists a unique endemic equilibrium and the endemic equilibrium is globally attractive when R 0 > 1 . We estimate that the basic reproduction number R 0 = 0.5320 (95% CI (0.3060, 0.7556)) in Jiangsu Province, which means that TB epidemic will die out. However, we find that the annual number of new TB cases by 2050 is 1,151 (95%CI: (138, 8,014)), which means that it is challenging to achieve the goal of WHO by 2050. To this end, we evaluate the possibility of achieving the goals of WHO if we start vaccinating adults and reduce diagnostic delay in 2025. Our results demonstrate that when the diagnostic delay is reduced from longer than four months to four months, or 20% adults are vaccinated, the goal of WHO in 2050 can be achieved, and 73,137 (95%CI: (23,906, 234,086)) and 54,828 (95%CI: (15,811, 206,468)) individuals will be prevented from being infected from 2025 to 2050, respectively. The modeling approaches and simulation results used in this work can help policymakers design control measures to reduce the prevalence of TB.

RESUMEN

Tuberculosis remains a large health threat, despite the availability of the tuberculosis vaccine, BCG. As BCG efficacy gradually decreases from adolescence, BCG-Prime and antigen-booster may be an efficient strategy to confer vaccine efficacy. Mycobacterial DNA-binding protein 1 (MDP1, namely Rv2986c, hupB or HU) is a major Mycobacterium tuberculosis protein that induces vaccine-efficacy by co-administration with CpG DNA. To produce MDP1 for booster-vaccine use, we have created recombinant MDP1 produced in both Escherichia coli (eMDP1) and Mycolicibacterium smegmatis (mMDP1), an avirulent rapid-growing mycobacteria. We tested their immunogenicity by checking interferon (IFN)-gamma production by stimulated peripheral blood cells derived from BCG-vaccinated individuals. Similar to native M. tuberculosis MDP1, we observed that most lysin resides in the C-terminal half of mMDP1 are highly methylated. In contrast, eMDP1 had less post-translational modifications and IFN-gamma stimulation. mMDP1 stimulated the highest amount of IFN-gamma production among the examined native M. tuberculosis proteins including immunodominant MPT32 and Antigen 85 complex. MDP1-mediated IFN-gamma production was more strongly enhanced when combined with a new type of CpG DNA G9.1 than any other tested CpG DNAs. Taken together, these results suggest that the combination of mMDP1 and G9.1 possess high potential use for human booster vaccine against tuberculosis.

RESUMEN

Real-time evaluation (RTE) supports populations (e.g., persons experiencing homelessness (PEH) to engage in evaluation of health interventions who may otherwise be overlooked. The aim of this RTE was to explore the understanding of TB amongst PEH, identify barriers/facilitators to attending screening for PEH alongside suggestions for improving TB-screening events targeting PEH, who have high and complex health needs. This RTE composed of free-text structured one-to-one interviews performed immediately after screening at a single tuberculosis (TB) screening event. Handwritten forms were transcribed for thematic analysis, with codes ascribed to answers that were developed into core themes. All RTE participants (n=15) learned about the screening event on the day it was held. Key concerns amongst screening attendees included: stigma around drug use, not understanding the purpose of TB screening, lack of trusted individuals/services present, too many partner organizations involved, and language barriers. Facilitators to screening included a positive welcome to the event, a satisfactory explanation of screening tests, and sharing of results. A need for improved event promotion alongside communication of the purpose of TB screening amongst PEH was also identified. A lack of trust identified by some participants suggests the range of services present should be reconsidered for future screening events.

RESUMEN

OBJECTIVES: This study aimed to evaluate the risk of tuberculosis associated with the use of Janus kinase (JAK) inhibitors or biological disease-modifying antirheumatic drugs (bDMARDs) in patients diagnosed with rheumatoid arthritis (RA) in South Korea. METHODS: In this nationwide matched-cohort study, we retrospectively identified adult patients with new-onset RA from the National Health Insurance Service database who were prescribed bDMARDs or JAK inhibitors and recently underwent latent tuberculosis infection (LTBI) screening during 2012‒2021, and followed them up until the end of 2022 for the development of active tuberculosis. HRs were estimated using Cox proportional hazards regression in a propensity score-matched cohort. RESULTS: Among 16 760 matched patients with RA (3352 JAK inhibitor users and 13 408 bDMARD users), 18.8% received tuberculosis preventive therapy for LTBI. Overall, JAK inhibitor users had a significantly lower risk of tuberculosis than bDMARD users (HR (95% CI)=0.37 (0.22 to 0.62)). Among the patients treated for LTBI, patients with low treatment adherence had a significantly higher risk than those without LTBI (HR (95% CI)=2.78 (1.74 to 4.44)). Patients without LTBI and using JAK inhibitors had a significantly lower risk of tuberculosis across all ages and sexes compared with bDMARD users. CONCLUSION: Patients with RA using JAK inhibitors have a significantly lower risk of active tuberculosis than bDMARD users in South Korea; however, patients with RA having LTBI are equally at risk regardless of the treatment received (JAK inhibitor vs bDMARD). Therefore, vigilant tuberculosis monitoring, especially in patients with low adherence to tuberculosis preventive therapy, is essential.

RESUMEN

This study aims to analyze the feasibility of building an evaluative model for the management of the Tuberculosis Prevention and Control Program in the State of Roraima, located on the border between Brazil and Venezuela. This is an evaluability assessment, a type of study used as a pre-evaluation of the development and implementation stages of a program, as well as throughout its execution. The study was developed in stages comprising the: (i) definition of the intervention to be analyzed and its objectives and goals; (ii) construction of the intervention logical model; (iii) screening of parties interested in the evaluation; (iv) definition of the evaluative questions; and (v) design of the evaluation matrix. Four priority components were defined for the evaluation: management of the organization and implementation of tuberculosis (TB) prevention and control policy; epidemiological surveillance management; care network management; and management of expected/achieved results. In this model, and based on theoretical references, we defined the necessary resources, activities, outputs, outcomes, and the expected impact for each of the policy management components. The management of the TB control program is feasible for evaluation based on the design of its components, the definition of structure and process indicators, and relevant results for the analysis of the management of TB prevention and control actions, as well as its influence on compliance with the agreed indicators and targets aiming at eradicating the disease by 2035.
