Human immunodeficiency virus-associated tuberculosis care in Botswana: evidence from a real-world setting.

BACKGROUND: Tuberculosis (TB) is among the world's top public health challenges and the leading killer of people with HIV, yet is a treatable disease. This study aimed to assess, in a real-world setting, the implementation of antiretroviral therapy (ART) and Cotrimoxazole preventive therapy (CPT) policy, specific interventions proven to benefit patients in HIV-associated TB care. METHODS: This retrospective cohort study was conducted in Botswana in the Serowe/Palapye district, a largely urban district with a high burden of HIV-associated TB with a high case fatality, at Segkoma and Palapye hospitals and their feeder clinics. Between 1 January 2013 and 31 December 2013, confirmed HIV-positive patients aged ≥15 years with a confirmed TB diagnosis and medical record available were included in the analysis. The Kaplan-Meier method was used to compare time to death for the group of patients on ART and the group of patients not on ART during TB treatment. Cox proportional hazard regression was undertaken to identify predictors of mortality. RESULTS: Of the 300 patients included in the study, 217 (72%) were ART experienced at TB diagnosis. Of these, 86 (40%) had TB within 3 months following ART initiation. Of the 83 (28%) patients who were ART-naïve at TB diagnosis, 40 (48%) were commenced on ART during TB treatment, with 24 (60%) patients commencing within 4 weeks following TB treatment initiation. The overall ART uptake was 84%, while cotrimoxazole preventive therapy uptake was 100%. There were 45 deaths (15%), ART-experienced patients during TB treatment accounted for 30 deaths (30/257; 14%), while those who were not ART-experienced during TB treatment accounted for 15 deaths (15/43; 35%). There was a significant difference in survival time between patients with no ART use during TB treatment and those with ART use during TB treatment (log rank p < 0.001). Patients with no ART use during TB treatment were more likely to die within the first 2 months. CONCLUSION: The implementation of CPT policy is a substantial success. Strengthening the implementation of ART policy could improve survival among HIV-associated TB patients.

Socio-Demographic Factors Influencing Malaria Vaccine Acceptance for Under-Five Children in a Malaria-Endemic Region: A Community-Based Study in the Democratic Republic of Congo.

Two novel vaccines against malaria are proposed as a complementary control tool to prevent and reduce Plasmodium falciparum related disease and death in under-five children from moderate to high malaria transmission regions. The Democratic Republic of Congo (DRC) has committed to eradicate malaria by 2030, and significant efforts have been deployed to strengthen control and elimination measures. We aimed to understand factors influencing the malaria vaccine acceptability among the general population in eastern DRC. We conducted a survey among adult Congolese in Bukavu in March 2022. The questionnaire was adapted from the Behavioral and Social Drivers of vaccine uptake (BeSD) framework and was administered online and physically. Multivariate logistic regressions were built, and estimates were represented as adjusted odds ratios (aOR) and corresponding 95% confidence intervals (95%CI). Out of 1612 adults (median age: 39 years, 46.15% female) surveyed, only 7.26% were aware of the malaria vaccine. However, 46.53% expressed willingness to vaccinate themselves, and 52.60% were open to vaccinating their under-five children. Adjusting for confounding factors, non-student/non-healthcare worker professions (aOR = 0.58, 95%CI [0.42-0.78]) and middle-income status (aOR = 1.87, 95%CI [1.25-2.80]) were significantly associated with self-vaccination acceptance. Age played a role in under-five child vaccination acceptability, with 25 to over 64 years showing increased acceptability compared to the 18-24 age group. Additionally, non-student/non-healthcare worker professions (aOR = 1.88, 95%CI [1.37-2.59]), medium education levels (aOR = 2.64, 95%CI [1.29-5.79]), and residing in semi-rural areas (aOR = 1.63, 95%CI [1.27-2.10]) were predictors of under-five child vaccination acceptance. The acceptability of the malaria vaccine for self and for under-five children was suboptimal for effective malaria control in this community in the DRC. Our study constitutes a call for the Expanded Program on Immunization to closely work with various stakeholders to strengthen risk communication for community engagement prior to and during the introduction of this novel and lifesaving tool, malaria vaccination.

COVID-19 Vaccine Hesitancy and Associated Oral Cholera Vaccine Hesitancy in a Cholera-Endemic Country: A Community-Based Cross-Sectional Study in the Democratic Republic of Congo.

COVID-19 vaccine hesitancy and its enablers shape community uptake of non-covid vaccines such as the oral cholera vaccine (OCV) in the post-COVID-19 era. This study assessed the impact of COVID-19 vaccine hesitancy and its drivers on OCV hesitancy in a cholera-endemic region of the Democratic Republic of Congo. We conducted a community-based survey in Bukavu. The survey included demographics, intention to take OCV and COVID-19 vaccines, reasons for COVID-19 hesitancy, and thoughts and feelings about COVID-19 vaccines. Poisson regression analyses were performed. Of the 1708 respondents, 84.66% and 77.57% were hesitant to OCV alone and to both OCV and COVID-19, respectively. Hesitancy to COVID-19 vaccines rose OCV hesitancy by 12% (crude prevalence ratio, [cPR] = 1.12, 95%CI [1.03-1.21]). Independent predictors of OCV hesitancy were living in a semi-urban area (adjusted prevalence ratio [aPR] = 1.10, 95%CI [1.03-1.12]), religious refusal of vaccines (aPR = 1.06, 95%CI [1.02-1.12]), concerns about vaccine safety (aPR = 1.05, 95%CI [1.01-1.11]) and adverse effects (aPR = 1.06, 95%CI [1.01-1.12]), as well as poor vaccine literacy (aPR = 1.07, 95%CI [1.01-1.14]). Interestingly, the belief in COVID-19 vaccine effectiveness reduced OCV hesitancy by 24% (aPR = 0.76, 95%CI [0.62-0.93]). COVID-19 vaccine hesitancy and its drivers exhibited a significant domino effect on OCV uptake. Addressing vaccine hesitancy through community-based health literacy and trust-building interventions would likely improve the introduction of novel non-COVID-19 vaccines in the post-COVID-19 era.

Health transformation toward universal healthcare coverage amidst conflict: examining the impact of international cooperation in Niger.

Background: Approximately 70% of Sub-Saharan African countries have experienced armed conflicts with significant battle-related fatalities in the past two decades. Niger has witnessed a substantial rise in conflict-affected populations in recent years. In response, international cooperation has aimed to support health transformation in Niger's conflict zones and other conflict-affected areas in Sub-Saharan Africa. This study seeks to review the available evidence on health interventions facilitated by international cooperation in conflict zones, with a focus on Niger. Methods: We conducted a systematic literature review (SLR) adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The search was conducted from 2000 to 4 September 2022 using MeSH terms and keywords to identify relevant studies and reports in Sub-Saharan Africa and specifically in Niger. Databases such as PubMed (Medline), Google Scholar, Google, and gray literature were utilized. The findings were presented both narratively and through tables and a conceptual framework. Results: Overall, 24 records (10 studies and 14 reports) that highlighted the significant role of international cooperation in promoting health transformation in conflict zones across Sub-Saharan Africa, including Niger, were identified. Major multilateral donors identified were the World Health Organization (WHO), United Nations Children's Fund (UNICEF), United Nations Fund for Population Activities (UNFPA), World Bank, United States Agency for International Development (USAID), European Union, European Commission Humanitarian Aid (ECHO), Global Fund, and Global Alliance for Vaccines and Immunization (GAVI). Most supports targeted maternal, newborn, child, adolescent, and youth health, nutrition, and psycho-social services. Furthermore, interventions were in the form of public health initiatives, mobile clinic implementation, data management, human resource capacity building, health information systems, health logistics, and research funding in conflict zones. Conclusion: This literature review underscores the significant engagement of international cooperation in strengthening and transforming health services in conflict-affected areas across Sub-Saharan Africa, with a particular focus on Niger. However, to optimize the effectiveness of healthcare activities from short- and long-term perspectives, international partners and the Ministry of Public Health need to re-evaluate and reshape their approach to health intervention in conflict zones.

Rabies mortality and morbidity associated with animal bites in Africa: a case for integrated rabies disease surveillance, prevention and control: a scoping review.

OBJECTIVE: The objective of this scoping review was to map the current situation and available evidence and gaps on rabies morbidity, mortality, integrated rabies surveillance programmes, and existing prevention and control strategies in Africa. METHODS: We conducted a systematic scoping review following the Joanna Briggs methodology and Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews checklist. Medline, Embase, CINAHL (EBSCOHost), Scopus, Web of Science and rabies web conferences were used to search for peer-reviewed publications between January 1946 and May 2020. Two researchers reviewed the studies and extracted data based on author (year) and region, study design and data collection duration, participants/comparators, interventions, control conditions/exposures and outcomes (rabies mortality and morbidity) and key findings/gaps/challenges. The results were reported narratively using Arksey and O'Malley's methodological framework. RESULTS: Electronic search yielded 2775 records, of which 43 studies were included. A total of 543 714 bite victims were censored through the included studies. Most of the victims were less than 15 years of age. The studies included rabies morbidity (21) and mortality (15) fluctuating in space and time across Africa depending on countries' rabies prevention and control practices (16). Others were surveillance (nine studies); surveillance and prevention (five studies); management and control (seven studies); and surveillance, prevention and control (six studies). We found challenges in rabies reporting, existing dog vaccination programmes and post-exposure prophylaxis availability or compliance. CONCLUSION: This study found challenges for dog rabies control and elimination in Africa and the need for a policy to drive the goal of zero dog-transmitted rabies to humans by 2030.This is an open-access article distributed in accordance with the Creative Commons Attribution Non Commercial (CC BY-NC 4.0) license, which permits others to distribute, remix, adapt, build on this work non-commercially, and license their derivative works on different terms, provided the original work is properly cited, appropriate credit is given, any changes made indicated and the use is non-commercial (see http://creativecommons.org/licenses/by-nc/4.0/).
