Chagas disease is named after the Brazilian physician Carlos Chagas, who discovered the disease in 1909. It is caused by the parasite Trypanosoma cruzi, which is transmitted to animals and people by insect vectors and is found only in the Americas (mainly, in rural areas of Latin America where pover...ty is widespread). Chagas disease (T. cruzi infection) is also referred to as American trypanosomiasis

The increasing amounts of official development assistance (ODA) for health have been aimed primarily at fighting HIV/AIDS, malaria and tuberculosis. Neglected tropical diseases (NTD), one of the most serious public health burdens among the most deprived communities, have only recently drawn the atte...ntion of major donors. While frequently stated, the low share
of funding for NTD control projects has not been calculated empirically. Our analysis of ODA commitments for infectious disease control for the years 2003 to 2007 confirms that Development Assistance Committee (DAC)-countries and multilateral donors have largely ignored funding NTD control projects. On average, only 0.6% of total annual health ODA was dedicated
to the fight against NTDs while the average share of control projects for HIV/AIDS was 36.3%, for malaria 3.6%, and for tuberculosis 2.2%. This allocation of health ODA does not reflect the diseases’ respective health burdens.

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 presentation 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.

This document focuses on making recommendations for the diagnosis and treatment of Chagas disease, an infection caused by Trypanosoma cruzi, the protozoan agent of a systemic parasitic disease. Methodology: These clinical practice guidelines were prepared following the WHO handbook for guideline dev...elopment (5). A multidisciplinary development group was formed, comprised of thematic experts, epidemiologists, methodologists, and users. Since there were no existing guidelines that could be adapted, the guidelines were developed from scratch.

Haiti faces a double burden of disease. Infectious diseases continue to be an issue, while non-communicable diseases have become a significant burden of disease. More attention must also be focused on the increase in worrying public health issues such as road... injuries, exposure to forces of nature and HIV/AIDS in specific age groups. To address the burden of disease, sustained actions are needed to promote better health in Haiti and countries with similar challenges.

Demographic and epidemiological transitions are changing the age structure of the population and the most common diseases. Non-communicable respiratory diseases are an increasing problem at both ends of the age range in low-income and middle-income countries. In children, who represent a large propo...rtion of the total population, the increasing problem of asthma is a strain on health services. Improved survival of the older population is increasing the proportion of morbidity and mortality attributable to chronic lung diseases. Health services in low-resource countries are poorly adapted to treating chronic diseases. Designed to respond episodically to acute disease, almost all historical investment has focused on infectious diseases. Crucial to the successful management of chronic diseases is an infrastructure designed to support pro-active management, providing not only an accurate diagnosis, but also a secure supply of cost effective drugs at an affordable price. The absence of such an infrastructure in many countries and the market failure that makes drugs generally more expensive in low-resource regions means that many people with chronic non-communicable lung diseases are not given effective treatment. This has damaging economic consequences. The common causes of poor lung health in lowincome countries are not the same as those in richer countries, and there is a need to study why they are so common and how best to manage them.

This report is primarily intended for the community of policymakers and researchers concerned about the rising risks of domestic, regional, and global infectious disease epidemics, and the collective failure to take the coordinated actions required to reduce such risks. These risks include the expec...ted health, economic, and societal costs that are borne by countries, regions, and even all nations in the case of pandemics (which are worldwide epidemics). These risks also include the consequences of increasing antimicrobial resistance (AMR) and its spread within regions and globally. A necessary first step is to monitor whether a broad range of stakeholders are acting to prevent outbreaks from becoming epidemics, whether their capacities to respond to epidemics are robust, and whether preparedness to respond to pandemics and limit the resulting economic and health damage is improving. Analyzing the adequacy of these efforts is vitally important for the decisions of policymakers to invest in the public health and disaster-risk management capacities. Early and effective control of disease outbreaks prevents substantial health and economic costs whether or not the disease can spread globally and become a pandemic.

The past two decades have witnessed changes in how humans live. Travel and trade, rapid urbanization, limited access to health care as well as environmental degradation and other trends all create the conditions for epidemics to thrive and grow. At the same time, the science and knowledge around inf...ectious hazards are constantly evolving, demanding better response to health emergencies.
This introductory level online course aims to equip frontline responders with the latest know-how to manage outbreaks of known and emerging epidemic-prone diseases in the 21st century. This course focuses on 13 infectious hazards, offering the most relevant scientific, technical and operational knowledge through video presentations and self-tests.
The course will take approximately 6 hours to finish.

.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 mech...anisms 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.

The Fifty-first World Health Assembly adopted resolution WHA51.11 in 1998, which targets the
global elimination of trachoma as a public health problem by 2020 (1). The strategy recommended
to achieve that goal is encapsulated by the acronym “SAFE”, which represents: Surgery for
individuals wi...th trachomatous trichiasis (TT; the late blinding stage of trachoma); and Antibiotics,
Facial cleanliness and Environmental improvement (2). The A, F and E interventions are delivered to
entire districts in which active (inflammatory) trachoma is common in order to treat ocular infection
with Chlamydia trachomatis, the causative organism of trachoma, and sustainably reduce its
transmission.

This threat assessment addresses the implications of the ongoing Marburg virus disease (MVD) outbreak in
Rwanda for the European Union/European Economic Area (EU/EEA). MVD is a severe disease in humans and,
although uncommon, it has the potential to cause epidemics with significant case fatality. ...All recorded MVD
outbreaks to date have originated in Africa. MVD is not an airborne disease and is considered not to be
contagious before symptoms appear. Direct contact with the blood and other body fluids of infected people
and animals or indirect contact with contaminated surfaces and materials like clothing, bedding and medical
equipment is required for transmission. The risk of infection is minimised when proper infection prevention and
control precautions are strictly followed. There is no approved treatment or vaccine for MVD; however, several
pharmaceuticals and candidate MVD vaccines are under investigation.
