Integrating the multiple dimensions of the problem into a coherent approach adapted to field realities and needs represents an immense challenge, but the payoff is more effective and sustainable experiences, with higher social awareness..., increased case detection and follow-up, improved adherence to care, and integrated participation of various actors from multiple action levels. Information, Education, and Communication (IEC) initiatives have great potential for impact in the implementation of multidimensional programs of prevention and control successfully customised to the diverse and complex contexts where Chagas disease persists.

Mosquitoes, flies, bugs and other vectors transmit viruses, parasites and bacteria that infect millions of people globally. They cause many diseases, including malaria, dengue, leishmaniases, Chagas diseas...e and Zika virus disease.
The World Health Organization (WHO) has developed a new strategy to strengthen vector control worldwide. Member States welcomed this integrated approach at the 2017 World Health Assembly and adopted a resolution to support the strategy.

Volume 2016 | Article ID 5310718 | https://doi.org/10.1155/2016/5310718. Buruli ulcer (BU) is a necrotizing cutaneous infection caused by Mycobacterium ulcerans. Early diagnosis is crucial to prevent morbid effects and misuse of drugs. We review developments in laboratory diagnosis of BU, discuss li...mitations of available diagnostic methods, and give a perspective on the potential of using aptamers as point-of-care.

This manual is addressed to health care providers dealing with Mycobacterium ulcerans disease (Buruli ulcer). The manual aims to achieve a better understanding of the disease, its clinical presentat...ion and its surgical management. The manual is aimed particularly at district health care providers. A comprehensive protocol, adapted to each form and stage of the disease, is presented together with comments on the levels of resources and capabilities necessary
to shorten the length of treatment, to prevent complications and to minimize undesired sequelae and thus to obtain the best possible outcome for each patient. Some sections include advice relevant to surgeons (e.g. relating to bone infection). However, the level to which particular comments are intended to apply should be clear from the context.

It is Zika virus (ZIKV) that most often causes these neurological effects it appears to be the only arbovirus than can cause congenital malformations such as microcephaly. In any case, more scientific tests are needed to establish the causal relationship between the virus and this malformation (7-10...).
This document is a practical tool designed to help health workers improve clinical diagnosis and provide timely care for patients infected
with the dengue, chikungunya, or Zika virus. It is intended mainly for
health workers in primary care facilities where laboratory diagnosis of
arboviruses is not always available. However, this guide may also be
very useful in hospitals that provide second- and third-level care, as it
describes the clinical manifestations of each of the three most important
arboviral diseases currently found in the Region, the elements for
differential diagnosis, and their clinical behavior.

.Chronic manifestations of Chagas disease present as disabling and life-threatening condi-tions affecting mainly the cardiovascular and gastrointestinal systems. Although meaningful... research has outlined the different molecular mechanisms underlying Trypanosoma cruzi’s infection and the host-parasite interactions that follow, prompt diagnosis and treatment remain a challenge, particu-larly in developing countries and also in those where the disease is considered non-endemic. This review intends to present an up-to-date review of the parasite’s life cycle, genetic diversity, virulence factors, and infective mechanisms, as well as the epidemiology, clinical presentation, diagnosis, and treatment options of the main chronic complications of Chagas disease.

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 cr...uzi transmission in Latin American settings where the 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.

Chagas disease (CD) is caused by the parasite Trypanosoma cruzi, and it is endemic in Central, South America, Mexico and the South of the United States. It is an important cause of early mo...rtality and morbidity, and it is associated with poverty and stigma. A third of the cases evolve into chronic cardiomyopathy and gastrointestinal disease. This review proposes strategies to address challenges faced by non-endemic countries

This chapter focuses on the strategic and operational challenges in the clinical drug development of a novel antitrypanosomal agent for Chagas disease. The various elements that contribute to a robust assessment of treatment effect including dose selection, choice of patient population, trial methodology, endpoint measures, and regulatory perspectives are discussed. The learnings herein should serve as resource to help researchers and other stakeholders optimize their clinical development plans and speed delivery of new medicines to patients with Chagas disease.

La enfermedad de Chagas, también conocida como tripanosomiasis americana, es causada por el parásito Trypanosoma cruzi. La forma más común de contraer la infección es a través del contacto con las heces de un insecto triatominio (conocido con los nombres de chinche besucona, benchuca, vinchuca..., chipo o barbeiro), el cual se alimenta de la sangre de seres humanos y animales.
