Population movements have turned Chagas disease (CD) into a global public health problem. Despite the successful implementation of subregional initiatives to control vectorial and transfusional Trypanosoma cruzi transmission in Latin American settings where t...he disease is endemic, congenital CD (cCD) remains a significant challenge. In countries where the disease is not endemic, vertical transmission plays a key role in CD expansion and is the main focus of its control. Although several health organizations provide general protocols for cCD control, its management in each geopolitical region depends on local authorities, which has resulted in a multitude of approaches. The aims of this review are to (i) describe the current global situation in CD management, with emphasis on congenital infection, and (ii) summarize the spectrum of available strategies, both official and unofficial, for cCD prevention and control in countries of endemicity and nonendemicity. From an economic point of view, the early detection and treatment of cCD are cost-effective. However, in countries where the disease is not endemic, national health policies for cCD control are nonexistent, and official regional protocols are scarce and restricted to Europe. Countries of endemicity have more protocols in place, but the implementation of diagnostic methods is hampered by economic constraints. Moreover, most protocols in both countries where the disease is endemic and those where it is not endemic have yet to incorporate recently developed technologies. The wide methodological diversity in cCD diagnostic algorithms reflects the lack of a consensus. This review may represent a first step toward the development of a common strategy, which will require the collaboration of health organizations, governments, and experts in the field.

The 2018 NDHS is a national sample survey that provides up-to-date information on demographic and health indicators. The sample was selected using a stratified, two-stage cluster design, with enumeration areas (EAs) as the sampling units for the first stage. The second stage was a complete listing o...f households carried out in each of the 1,400 selected EAs. The target groups were women age 15-49 and men age 15-59
in randomly selected households across Nigeria. A representative sample of approximately 42,000 households was selected for the survey. One-third of the households (14,000) were selected for malaria, anaemia, and genotype testing of children age 6-59 months. Also, in the subsample of households selected
for the men’s survey, one eligible woman in each household was randomly selected for additional questions regarding domestic violence. Specifically, information was collected on fertility levels, marriage, fertility preferences, awareness and use of family planning methods, child feeding practices, nutritional status of women and children, adult and childhood mortality, awareness and attitudes regarding
HIV/AIDS, and female genital mutilation. The survey also assessed the nutritional status (according to weight and height measurements) of women and children in these households. In addition to presenting national estimates, the report provides estimates of key indicators for both rural and urban areas, the country’s six geopolitical zones and 36 states, and the Federal Capital Territory (FCT).

Africa’s health sector is facing an unprecedented financing crisis, driven by a sharp decline of 70% in Official Development Assistance (ODA) from 2021 to 2025 and deep-rooted structural vulnerabilities. This collapse is placing immense pressure on Africa’s already fragile health systems as ODA ...is seen as the backbone of critical health programs: pandemic preparedness, maternal and child health services, disease control programs are all at
risk, threatening Sustainable Development Goal 3 and Universal Health Coverage. Compounding this is Africa’s spiraling debt, with countries expected to service USD 81 billion by 2025—surpassing anticipated external financing inflows—further eroding fiscal space for health investments. Level of domestic resources is low. TThe Abuja Declaration of 2001, a pivotal commitment made by African Union (AU) member states, aimed to reverse this trend by pledging to allocate at least 15% of national budgets to the health sector. However, more than two decades later, only three countries—Rwanda, Botswana, and Cabo Verde—have
consistently met or exceeded this target (WHO, 2023). In contrast, over 30 AU member states remain well below the 10% benchmark, with some allocating as little as 5–7% of their national budgets to health.
In addition, only 16 (29%) of African countries currently have updated versions of National Health Development Plan (NHDP) supported by a National Health Financing Plan (NHFP). These two documents play a critical role in driving internal resource mobilisation. At the same time, public health emergencies are surging, rising 41%—from 152 in 2022 to
213 in 2024—exposing severe under-resourcing of health infrastructure and workforce. Recurring outbreaks (Mpox, Ebola, cholera, measles, Marburg…) alongside effects of climate change and humanitarian crises in Eastern DRC, the Sahel, and Sudan, are overwhelming systems stretched by chronic underfunding. The situation is worsened by Africa’s heavy dependency with over 90% of vaccines, medicines, and diagnostics being externally sourced—leaving countries vulnerable to global supply chain shocks. Health worker shortages persist, with only 2.3 professionals
per 1,000 people (below the WHO’s recommended 4.45), and fewer than 30% of systems are digitized, undermining disease surveillance and early warning. Without decisive action, Africa CDC projects the continent could reverse two decades of health progress, face 2 to 4 million additional preventable deaths annually, and a heightened risk of a pandemic emerging from within. Furthermore, 39 million more
Africans could be pushed into poverty by 2030 due to intertwined health and economic shocks. This is not just a sectoral crisis—it is an existential threat to Africa’s political, social, and economic resilience, and global stability. In response, African leaders, under Africa CDC’s stewardship, are advancing a comprehensive three-pillar strategy centered on domestic resource mobilization, innovative financing, and blended finance.

The objective of the study was the validation and implementation of GeneXpert MTB/RIF for routine use in the rapid detection of tuberculosis and sensitivity to rifampicin in clinical samples; for this, 1592 respiratory samples were collected and analyzed in the laboratory of Instituto Nacional de In...vestigación en Salud Pública Guayaquil. The analysis of the results of GeneXpert in comparison with smear microscopy showed an initial sensitivity of 99.8% and specificity of 93.2%; The analysis of discrepancies using the results of the culture as a reference method showed that the GeneXpert results considered false negatives turned out to be true negatives, the same happens with the false positives that correspond to true positives. Recalculated the sensitivity and specificity of the GeneXpert was 99.8% and 100% correspondingly. The comparison with the drugs susceptibility test showed a sensitivity of 91.4% and a specificity of 95.5% for the GeneXpert MTB/RIF system. It is concluded that the implementation of the GeneXpert system allows solution to certain problems associated with the application of conventional diagnostic methodologies, decreasing the waiting times, and increasing the sensitivity and specificity in the diagnosis of drug-resistant tuberculosis, thus generating a valuable opportunity for early diagnosis.
