In recent years, conditions in the Region of the Americas have been highly favorable for the introduction and spread of arthropod-borne viral infections (arboviral diseases). Although dengue has been circulating for over 400 years, the number of cases reported since the year 2000 represents an unprecedented increase, with four serotypes in circulation. Since that year, 19.6 million cases of dengue have been reported to PAHO/WHO, including more than 800,000 severe cases and over 10,000 deaths. In 2015 and 2016 alone, more than 4.8 million cases were reported, 17,000 of them severe, resulting in 2,000 deaths. Despite a 23% reduction in the dengue case-fatality rate in the last six years (from 0.069% to 0.053%), the continued risk of severe disease and even death poses a serious public health problem in the Americas. Today, arboviruses present an extremely complex and unstable epidemiological situation, given the simultaneous epidemic circulation of three arboviral diseases and the risk that others could become epidemics, for example, Mayaro fever. Countries are aware that this complex situation can only be addressed with a comprehensive and multidisciplinary approach. The development of IMS-arbovirus is part of a history of technical cooperation between PAHO/WHO and the countries and territories of the Americas. It is based on the lessons learned during the development and implementation of national IMS-dengue programs in recent years. This history of cooperation is not new. It dates back to October 1947, with the adoption of Resolution CD1.R1 during the first Directing Council of PAHO. This resolution stated that the solution to the problem of urban yellow fever would be the eradication of Ae. aegypti in the entire hemisphere. The success of that campaign was demonstrated in 1962, with the eradication of this vector in 18 countries in the Region and several Caribbean islands.

The IMS-Arbovirus is a model that provides a methodological framework for arboviral disease prevention and control. It divides the compendium of actions to be taken into the following components, which are not listed in their order of importance: management, epidemiology (with emphasis on health surveillance), laboratory, patient care (clinical), integrated vector management (IVM), and environment (with emphasis on water, sanitation, and hygiene). It also proposes common crosscutting themes for each component: operations research and health communication and promotion for behavioral change. Each component and crosscutting theme is overseen and executed by personnel trained for this purpose. The Integrated Management Strategy for Arbovirus Disease Prevention and Control in the Americas contains a group of indicators selected by the countries, and a trained professional regularly conducts an informal evaluation of the strategy. This evaluation may be based on what the coordinator for each component or the participants in the process report, often based only on their own experiences. Generically, this methodology attempts to organize ideas and the methodologies that should be followed for best performance in an evaluation.

Integrated vector management (IVM) is a rational decision-making process for optimal use of resources for vector control. The aim of the IVM approach is to contribute to achievement of the global targets set for vector-borne disease control, by making vector control more efficient, cost-effective, ecologically sound and sustainable. Use of IVM helps vector control programs to find and use more local evidence, to integrate interventions where appropriate and to collaborate within the health sector and with other sectors, as well as with households and communities. By reorientating to IVM, vector control programs will be better able to meet the growing challenges in the control of malaria, dengue and other vector-borne diseases in the face of dwindling public sector human and financial resources. This handbook presents an operational framework to guide managers and those implementing vector-borne disease control programs in designing more efficient, cost-effective systems. As a national IVM policy and an intersectoral steering committee are essential for establishing IVM as a national strategy, the handbook begins with the policy and institutional framework for IVM. Policy analysis is a means for identifying options for policy reform and suggesting instruments for implementing policy. IVM transforms the conventional system of vector control by making it more evidence-based, integrated and participative. This may require changes in roles, responsibilities and organizational links. The transition to IVM involves both reorientation of vector-borne disease control programs and embedding IVM within local health systems. Intersectoral partnerships and collaboration at both national and local levels will result in cost savings and benefits to other health services. Other relevant sectors, such as agriculture, environment, mining, industry, public works, local government and housing, should incorporate IVM and vector control into their own activities to prevent vector proliferation and disease transmission. Planning and implementing IVM involve assessing the epidemiological and vector situation at country level, analyzing the local determinants of disease, identifying and selecting vector control methods, assessing requirements and resources and designing locally appropriate implementation strategies. Solid evidence on the cost-effectiveness of interventions and their underlying parameters and a comprehensive vector surveillance system are essential for locally appropriate decision-making. Capacity-building, in particular human resource development, is a major challenge, because the IVM strategy requires skilled staff and adequate infrastructure at central and local levels. The handbook outlines the core functions and essential competence required for IVM at central and local levels, complementing a separate set of documents containing the Core structure for training curricula on integrated vector management and associated training materials. Like any new approach, IVM must be actively advocated and communicated in order to become established. The handbook lays out the elements and processes of IVM to enable policy-makers, donors and implementing partners to use it for vector-borne disease control. During the period of transition and consolidation of an IVM strategy, regular feedback is required on performance and impact in order to ensure continued support. The general public must also be made aware of the strategy and participate in its implementation. The communication tools for reaching the public are the media and various types of educational interventions to increase their knowledge and skills, which should lead to behavioral change and empowerment. The final section presents a comprehensive framework for monitoring and evaluation of IVM, covering aspects discussed in the previous sections. Indicators and methods for measuring process, outcomes and impact are proposed.

Vector-borne infectious diseases, such as malaria, dengue fever, yellow fever, and plague, cause a significant fraction of the global infectious disease burden; indeed, nearly half of the world's population is infected with at least one type of vector-borne pathogen (CIESIN, 2007; WHO, 2004a). Vector-borne plant and animal diseases, including several newly recognized pathogens, reduce agricultural productivity and disrupt ecosystems throughout the world. These diseases profoundly restrict socioeconomic status and development in countries with the highest rates of infection, many of which are located in the tropics and subtropics. Although this workshop summary provides an account of the individual presentations, it also reflects an important aspect of the Forum philosophy. The workshop functions as a dialogue among representatives from different sectors and allows them to present their beliefs about which areas may merit further attention. These proceedings summarize only the statements of participants in the workshop and are not intended to be an exhaustive exploration of the subject matter or a representation of consensus evaluation. Vector-Borne Diseases : Understanding the Environmental, Human Health, and Ecological Connections, Workshop Summary (Forum on Microbial Threats) summarizes this workshop.

This toolkit for integrated vector management (IVM) is designed to help national and regional programme managers coordinate across sectors to design and run large IVM programmes. It is an extension of earlier guidance and teaching material published by the World Health Organization (WHO): Handbook for integrated vector management Monitoring and evaluation indicators for integrated vector management Guidance on policy-making for integrated vector management and Core structure for training curricula on integrated vector management. The toolkit provides the technical detail required to plan implement monitor and evaluate an IVM approach. IVM can be used when the aim is to control or eliminate vector-borne diseases and can also contribute to insecticide resistance management. This toolkit provides information on where vector-borne diseases are endemic and what interventions should be used presenting case studies on IVM as well as relevant guidance documents for reference. The diseases that are the focus of this toolkit are malaria lymphatic filariasis dengue leishmaniasis onchocerciasis human African trypanosomiasis and schistosomiasis. It also includes information on other viral diseases (Rift Valley fever West Nile fever Chikungunya yellow fever) and trachoma. If other vector-borne diseases appear in a country or area vector control with an IVM approach should be adopted as per national priorities. Malaria as one of the most important vector-borne diseases in sub-Saharan Africa is the main focus of this document. Programmes targeting other vector-borne diseases can learn from the experiences gained from malaria vector control and presented here.

"The presence, or absence, of neglected tropical diseases (NTDs) can be seen as a proxy for poverty and for the success of interventions aimed at reducing poverty. Today, coverage of the public-health interventions recommended by the World Health Organization (WHO) against NTDs may be interpreted as a proxy for universal health coverage and shared prosperity - in short, a proxy for coverage against neglect. As the world's focus shifts from development to sustainable development, from poverty eradication to shared prosperity, and from disease-specific goals to universal health coverage, control of NTDs will assume an important role towards the target of achieving universal health coverage, including individual financial risk protection. Success in overcoming NTDs is a "litmus test" for universal health coverage against NTDs in endemic countries. The first WHO report on NTDs (2010) set the scene by presenting the evidence for how these interventions had produced results. The second report (2013) assessed the progress made in deploying them and detailed the obstacles to their implementation. This third report analyses for the first time the investments needed to achieve the scale up of implementation required to achieve the targets of the WHO Roadmap on NTDs and universal coverage against NTDs. INVESTING TO OVERCOME THE GLOBAL IMPACT OF NEGLECTED TROPICAL DISEASES presents an investment strategy for NTDs and analyses the specific investment case for prevention, control, elimination and eradication of 12 of the 17 NTDs. Such an analysis is justified following the adoption by the Sixty-sixth World Health Assembly in 2013 of resolution WHA6612 on neglected tropical diseases, which called for sufficient and predictable funding to achieve the Roadmap's targets and sustain control efforts. The report cautions, however, that it is wise investment and not investment alone that will yield success. The report registers progress and challenges and signals those that lie ahead. Climate change is expected to increase the spread of several vector-borne NTDs, notably dengue, transmission of which is directly influenced by temperature, rainfall, relative humidity and climate variability primarily through their effects on the vector. Investments in vector-borne diseases will avoid the potentially catastrophic expenditures associated with their control. The presence of NTDs will thereby signal an early warning system for climate-sensitive diseases. The ultimate goal is to deliver enhanced and equitable interventions to the most marginalized populations in the context of a changing public-health and investment landscape to ensure that all peoples affected by NTDs have an opportunity to lead healthier and wealthier lives."--Publisher's description.

Zoonotic diseases represent one of the leading causes of illness and death from infectious disease. Defined by the World Health Organization, zoonoses are "those diseases and infections that are naturally transmitted between vertebrate animals and man with or without an arthropod intermediate." Worldwide, zoonotic diseases have a negative impact on commerce, travel, and economies. In most developing countries, zoonotic diseases are among those diseases that contribute significantly to an already overly burdened public health system. In industrialized nations, zoonotic diseases are of particular concern for at-risk groups such as the elderly, children, childbearing women, and immunocompromised individuals. The Emergence of Zoonotic Diseases: Understanding the Impact on Animal and Human Health, covers a range of topics, which include: an evaluation of the relative importance of zoonotic diseases against the overall backdrop of emerging infections; research findings related to the current state of our understanding of zoonotic diseases; surveillance and response strategies to detect, prevent, and mitigate the impact of zoonotic diseases on human health; and information about ongoing programs and actions being taken to identify the most important needs in this vital area.

Histoplasmosis is a disease caused by the fungus Histoplasma capsulatum. This disease is highly endemic in some regions of North America, Central America, and South America and is also reported in certain countries of Asia and Africa. It often affects people with impaired immunity, including people living with HIV, among whom the most frequent clinical presentation is disseminated histoplasmosis. The symptoms of disseminated histoplasmosis are non-specific and may be indistinguishable from those of other infectious diseases, especially disseminated tuberculosis (TB), thus complicating diagnosis and treatment. Histoplasmosis is one of the most frequent opportunistic infections caused by fungal pathogens among people living with HIV in the Americas and may be responsible for 5-15% of AIDS-related deaths every year in this Region. These guidelines aim to provide recommendations for the diagnosis, treatment, and management of disseminated histoplasmosis in persons living with HIV. Although the burden of disease is concentrated in the Americas, the recommendations presented within these guidelines are applicable globally. These guidelines were produced in accordance with the World Health Organization (WHO) handbook for guideline development. The Guideline Development Group elaborated the final recommendations based on a systematic review of scientific literature and critical evaluation of the evidence available using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach. These guidelines are intended for health-care providers, HIV program managers, policy-makers, national treatment advisory boards, researchers, and other professionals involved in caring for people who either have or may be at risk of developing disseminated histoplasmosis.
