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.

Trypanosoma cruzi is the etiological agent of Chagas disease (CD), considered one of the most important parasitic infections in Latin America. Between 25 and 90 million humans are at infection risk via at least one of multiple infection mechanisms. Under natural conditions, the principal transmissio...n modes are transplacental or via one of more than 140 hematophagous triatomine bugs (Reduviidae: Triatominae). Triatomines acquire the parasite from mammal reservoirs due to their obligate blood-feeding (albeit triatomines can also feed on non-reservoir vertebrates such as birds and reptiles). The disease burden for CD in the Latin America and Caribbean region, based on disability-adjusted life-years (DALYs), is at least five times greater than that of malaria, and is approximately one-fifth that of HIV/AIDS. In recent decades, CD has extended to other continents outside natural reservoir or vector distributions due to human migration, with a minimum estimated 10 million individuals infected worldwide.

Chagas disease caused by Trypanosoma cruzi is a public health issue in Latin America. This highly diverse parasite is divided into at least seven discrete typing units (DTUs) TcI-TcVI and Tcbat. Some DTUs have been associated with geographical distribution in epidemiological scenarios and clinical m...anifestations, but these aspects remain poorly understood. Many studies have focused on studying the parasite and its vectors/hosts, using a wide variety of genetic markers and methods. Here, we performed a systematic review of the literature for the last 20 years to present an update of DTUs distribution in the Americas, collecting ecoepidemiological information. We found that the DTUs are widespread across the continent and that there is a whole gamma of genetic markers used for the identification and genotyping of the parasite. The data obtained in this descriptor could improve the molecular epidemiology studies of Chagas disease in endemic regions.

Schistosomiasis is a neglected tropical disease of global medical and veterinary importance. As efforts to eliminate schistosomiasis as a public health problem and interrupt transmission gather momentum, the potential zoonotic risk posed by livestock Schistosoma species via viable hybridisation in s...ub-Saharan Africa have been largely overlooked. We aimed to investigate the prevalence, distribution, and multi-host, multiparasite transmission cycle of Haematobium group schistosomiasis in Senegal, West Africa.

Arsenical monotherapies were previously very successful for treating human African trypanosomiasis (HAT).
Melarsoprol resistance emerged as early as the 1970s and was widespread by the late 1990s.
Melarsoprol resistance represents the only example of widespread drug resistance in HAT patients wher...e the genetic mechanism has been established.
The current goal of elimination of HAT as a public health problem by 2020 may be undermined by the emergence and spread of resistance to current or new drugs.
Insights into potential resistance mechanisms for current and new drugs will facilitate predictions of the likelihood of resistance and will also facilitate rational approaches to minimizing, monitoring, and tackling the future emergence of resistance.

Despite the existence of criminal law, which is an important aspect of anti-FGM policies and programmes, there is not much research on the effects of cross-border practices that invalidate the law as a deterrent. Much remains unknown about the practice of cross-border FGM, specifically about gaps in... existing policy and legislation for managing cross-border FGM, as well as whether the existing interventions in the cross-border areas are sufficiently targeted to facilitate changes in social norms

The Event-based Surveillance Framework is intended to be used by authorities and agencies responsible for
surveillance and response. This framework serves as an outline to guide stakeholders interested in implementing
event-based surveillance (EBS) using a multisectoral, One Health approach. To ...that end, the document is arranged
in interlinked chapters and annexes that can be modified and adapted, as needed, by users.
This is a revised version of the original “Framework for Event-based Surveillance” that was published in 2018. This
framework does not replace any other available EBS materials, but rather builds on existing relevant or related
documents and serves as a practical guide for the implementation of EBS in Africa. This framework is aligned with
the third edition of the WHO Joint External Evaluation for the following indicators: strengthened early warning
surveillance systems that are able to detect events of significance for public health and health security (Indicator
D2.1); improved communication and collaboration across sectors and between National, intermediate and local
public health response levels of authority regarding surveillance of events of public health significance (Indicator
D2.2); and improved national and intermediate-level capacity to analyse data (Indicator D2.3). As countries begin
to implement and demonstrate EBS functionality they will ensure an increase in JEE scores and progress towards
meeting the requirements outlined in the IHR3F
Additionally, in African Union Member States that have adopted the Integrated Disease Surveillance and
Response (IDSR) strategy, this document is a complement to and can enhance the implementation of IDSR,
especially for the 3rd edition (2019) that includes components related to EBS.

Esta é uma versão revisada da “Estrutura para Vigilância Baseada em Eventos” original, publicada em
2018. Essa estrutura não substitui nenhum outro material disponível do EBS, mas se baseia em
documentos relevantes ou relacionados existentes e serve como um guia prático para a
implementação do EBS na África. Essa estrutura está alinhada com a terceira edição da Avaliação
Externa Conjunta da OMS para os seguintes indicadores: sistemas de vigilância de alerta precoce
fortalecidos que são capazes de detectar eventos importantes para a saúde pública e a segurança da
saúde (Indicador D2.1); melhor comunicação e colaboração entre os setores e entre os níveis de
autoridade de resposta à saúde pública nacional, intermediário e local em relação à vigilância de
eventos importantes para a saúde pública (Indicador D2.2); e melhor capacidade nacional e
intermediária de analisar dados ( Indicador D2.3). À medida que os países começarem a implementar
e demonstrar a funcionalidade do EBS, eles garantirão um aumento nas pontuações do JEE e
progredirão no cumprimento dos requisitos descritos no IHR 3F.

The Africa Centres for Disease Control and Prevention (Africa CDC) Biosafety and Biosecurity Initiative was launched by the Africa CDC in April 2019 with the aim of strengthening the African Union (AU) Member States’ biosafety and biosecurity systems and enabling them to comply with national and i...nternational requirements for biosafety and biosecurity including the International Health Regulations (IHR) (2005), the Biological Weapons Convention (BWC), and United Nations Security Council Resolution (UNSCR) 1540 and the multi-country Global Health Security Agenda (GHSA). The World Health Organization (WHO) Joint External Evaluation (JEE) and the Global Health Security Index report confirmed the known capacity gaps in biosafety and biosecurity among Africa Union Member (AU).
The regional consultations by Africa CDC conducted between 2019-2021 highlighted the deficiency or limited availability of standardized and regionally recognized training programs in the continent, limiting biosafety and biosecurity capacity building efforts in the region. In response, Africa CDC working with AU Member States developed a home grown, implementable and accessible professional training and certification program that is both recognized and endorsed by AU Member States. The Regional Training and Certification Program for Biosafety and Biosecurity Professionals, for African Biosafety and Biosecurity Professionals (RTCP-BBP) has four (4) areas of specialization, namely
Selection, Installation, Maintenance and Certification of Biological Safety Cabinets
Biorisk Management
Design and Maintenance of Facilities Handling High Risk Pathogens (Biocontainment Engineering)
Biological Waste management

Annual and medium-term budget preparation processes are the platforms through which specific plans are transformed into actual resource allocation decisions. The aim of this Process Guide is to support key stakeholders involved in these processes (such as the Cabinet, Ministries of Finance and Healt...h, the Parliament, citizens, media, and civil society organizations) to reorient budgetary arrangements in order to facilitate the ability of national governments to respond to the COVID-19 pandemic by delivering, therapeutics, diagnostics, and vaccine services to their populations. Reorienting budgetary arrangements positions governments to sustain the capacity to mitigate and respond to COVID-19 while concurrently delivering other essential health services and working towards Universal Health Coverage (UHC). The reorientation process is an opportunity to better align budgetary arrangements to sustain systemic capacity to prevent emerging health threats over the short, medium, and long terms.

The greatest risk to persons engaging in international medical emergency response is poor preparation.
The In Control handbook hopes to provide a remedy.
At the time of writing, we are living through the Coronavirus (COVID-19) pandemic, a health emergency that disregards physical borders, brin...gs into focus social inequalities and affects people on every continent. This shared challenge requires unprecedented measures and the collaboration of the brightest minds to support global health protection through this crisis and beyond. Healthcare infrastructures have to be strengthened, public health capacities and processes upgraded, medical countermeasures and vaccinations found and psychosocial side-effects treated.
Solidarity is the normative order of the day and the human species has to collaborate to face this invisible threat. Hiding and living in fear is not an option in this interconnected world. We have both a responsibility and an opportunity to make substantial contributions to a safer, healthier and more sustainable future for us all.
The existence of this handbook is an impressive example of solidarity. Over 50 authors from more than 15 institutes and organisations have come together voluntarily within a very short time to make their expertise available and enable cross-sectoral thinking. Knowledge is bundled, resources are combined, information gaps are filled. The In Control handbook is not a theoretical treatise of possible dangers, but a collection of subject-matter expertise, written by experts and practitioners who have shaped health topics over the past 20 years in the most diverse corners of the world.
The Centre for International Health Protection at the Robert Koch Institute (RKI) is collaborating with its partners and investing heavily in the build-up of operational know-how and capacity to support health crisis response abroad. This is done by preparing and enabling professionals to deploy safely across the world to assist those in need. In Control addresses the multi-faceted challenges of an international deployment. Readers will find not only technical medical information, but also insights into, for example, the fragility of our environment, the cultural differences that influence risk communication or the dilemmas arising from social distancing. Legal principles are highlighted, along with ethical guidance to ensure that our actions and decisions correspond to the highest moral standards.

Health facilities in the Region of the Americas frequently suffer the effects of health emergencies and disasters, which jeopardize their ability to provide services to the population. The STAR-H methodology helps staff responsible for health emergency and disaster risk management to identify and as...sess risks as part of strategic planning to improve facility preparedness. It is intended to help them develop, with a multi-hazard approach, a response framework with operating procedures to deal with hazards of any type, scale, or frequency; determine roles and responsibilities; facilitate the effective use of resources; undertake strategic planning exercises, and improve the preparedness of facilities to effectively respond to and recover from impacts. This methodology is designed for use in health facilities of any size and capacity, and makes it possible to generate historical reports and national or subnational risk profiles. This information can be used to develop an effective health emergency and disaster risk management program.
