A chronological map of the presence of Zika only in those countries for which there is evidence of indigenous transmission by mosquitos, excluding the many countries that have notified imported Zika infections.
There are indigenous communities at high risk in every country of the region. At stake are the lives of 45 million people who belong to more than 800 indigenous peoples. Of these, some 100 are spread across several countries, around 200 maintain voluntary isolation or are in initial contact, and nea...rly 500 are at risk of disappearing due to their reduced numbers. Due to their lower immune resistance, their lack of access to hospital care and the increasing penetration of extractive activities in their territories, indigenous communities in voluntary isolation or in initial contact are cause for particular concern.
Far from hospitals and the news cameras, indigenous people in Latin American become ill and die without access to the means needed to protect themselves. They face the pandemic in conditions of social exclusion, racism and discrimination, which highlights historical inequalities and extreme precariousness in basic and health services.

The 2020 Report analyzes global health spending for 190 countries from 2000 to 2018 and provides insights as to the health spending trajectory from the MDG era to the SDG era prior to the crisis of 2020. The report shows that global spending on health continually rose between 2000 and 2018 and reach...ed US$ 8.3 trillion or 10% of global GDP. The data also show that out-of-pocket spending has remained high in low and lower-middle income countries, representing greater than 40% of total health spending in 2018. We also report and summarize the data on expenditures for PHC, as well as by disease and intervention, including for immunization. The report also analyzes the available data on budget allocation in response to the COVID-19 crisis. In addition, we combine World Bank/IMF projections of the macroeconomic and fiscal impact of the crisis with an analysis of the historical determinants of health spending patterns and UHC indicators, and based on this, we draw out the likely implications of 2020 for future health spending, highlighting key policy and monitoring concerns.

Left unabated, climate change will have catastrophic effects on the health of present and future generations. Such effects are already seen in Europe, through more frequent and severe extreme weather events, alterations to water and food systems, and changes in the environmental suitability for infe...ctious diseases. As one of the largest current and historical contributors to greenhouse gases and the largest provider of financing for climate change mitigation and adaptation, Europe’s response is crucial, for both human health and the planet. To ensure that health and
wellbeing are protected in this response it is essential to build the capacity to understand, monitor, and quantify health impacts of climate change and the health co-benefits of accelerated action.

This report of the EFSA and ECDC presents the results of zoonoses monitoring activities carried out in 2020 in 27 EU Member States (MS) and nine non-MS. Key statistics on zoonoses and zoonotic agents in humans, food, animals and feed are provided and interpreted historically.
Carbon dioxide emissions are the primary driver of global climate change. It’s widely recognised that to avoid the worst impacts of climate change, the world needs to urgently reduce emissions. But, how this responsibility is shared between regions, countries, and individuals has been an endless p...oint of contention in international discussions.
This debate arises from the various ways in which emissions are compared: as annual emissions by country; emissions per person; historical contributions; and whether they adjust for traded goods and services. These metrics can tell very different stories.
We teamed up with the YouTube channel, Kurzgesagt, to produce a video which explored these different metrics in detail: ‘Who is responsible for climate change? – Who needs to fix it?’. All of the data and research featured in this video is contained in this article: below we look in detail at the many ways emissions are broken down.

Dengue is a mosquito-borne viral disease that occurs mainly in the tropics and subtropics but has a high potential to spread to new areas. Dengue infections are climate sensitive, so it is important to better understand how changing climate factors affect the potential for geographic spread and futu...re dengue epidemics. Vectorial capacity (VC) describes a vector's propensity to transmit dengue taking into account human, virus, and vector interactions. VC is highly temperature dependent, but most dengue models only take mean temperature values into account. Recent evidence shows that diurnal temperature range (DTR) plays an important role in influencing the behavior of the primary dengue vector Aedes aegypti. In this study, we used relative VC to estimate dengue epidemic potential (DEP) based on the temperature and DTR dependence of the parameters of A. aegypti. We found a strong temperature dependence of DEP; it peaked at a mean temperature of 29.3°C when DTR was 0°C and at 20°C when DTR was 20°C. Increasing average temperatures up to 29°C led to an increased DEP, but temperatures above 29°C reduced DEP. In tropical areas where the mean temperatures are close to 29°C, a small DTR increased DEP while a large DTR reduced it. In cold to temperate or extremely hot climates where the mean temperatures are far from 29°C, increasing DTR was associated with increasing DEP. Incorporating these findings using historical and predicted temperature and DTR over a two hundred year period (1901-2099), we found an increasing trend of global DEP in temperate regions. Small increases in DEP were observed over the last 100 years and large increases are expected by the end of this century in temperate Northern Hemisphere regions using climate change projections. These findings illustrate the importance of including DTR when mapping DEP based on VC.

Epidemiology
Chagas disease (American trypanosomiasis) is caused by the protozoan parasite Trypanosoma cruzi, and transmitted to humans by infected triatomine bugs, and less commonly by transfusion, organ transplant, from mother to infant, and in rare instances, by ingestion of contaminated food or... drink.1-4 The hematophagous triatomine vectors defecate during or immediately after feeding on a person. The parasite is present in large numbers in the feces of infected bugs, and enters the human body through the bite wound, or through the intact conjunctiva or other mucous membrane.
Vector-borne transmission occurs only in the Americas, where an estimated 8 to 10 million people have Chagas disease.5 Historically, transmission occurred largely in rural areas in Latin America, where houses built of mud brick are vulnerable to colonization by the triatomine vectors.4 In such areas, Chagas disease usually is acquired in childhood. In the last several decades, successful vector control programs have substantially decreased transmission rates in much of Latin America, and large-scale migration has brought infected individuals to cities both within and outside of Latin America.

Gambiense human African trypanosomiasis is a deadly infectious disease affecting West and Central Africa, South Sudan and Uganda, and transmitted between humans by tsetse flies. The disease has caused several major epidemics, the latest one in the 1990s. Thanks to recent innovations such as rapid di...agnostic tests for population screening, a single-dose oral treatment and a highly efficient vector control strategy, interruption of transmission of the causative parasite is now within reach. If indeed gHAT has an exclusively human reservoir, this could even result in eradication of the disease. Even if there were an animal reservoir, on the basis of epidemiological data, it plays a limited role. Maintaining adequate postelimination surveillance in known historic foci, using the newly developed tools, should be sufficient to prevent any future resurgence.

Rabies is a fatal viral zoonosis and serious public health problem.1 All mammals are believed to be susceptible to the disease, and for the purposes of this document, use of the term animal refers to mammals. The disease is an acute, progressive encephalitis caused by viruses in the genus Lyssavirus....
2 Rabies virus is the most important lyssavirus globally. In the
United States, multiple rabies virus variants are maintained in wild mammalian reservoir populations such as raccoons, skunks, foxes, and bats. Although the United States has been declared free from transmission of canine rabies virus variants, there is always a risk of reintroduction of these variants.The rabies virus is usually transmitted from animal to animal through bites. The incubation period is
highly variable. In domestic animals, it is generally 3 to 12 weeks, but can range from several days to months, exceeding 6 months.8 Rabies is communicable during the period of salivary shedding of rabies virus. Experimental and historic evidence documents that dogs, cats, and ferrets shed the virus for a few days prior to the onset of clinical signs and during illness. Clinical signs of rabies are variable and include inappetance, dysphagia, cranial nerve deficits, abnormal behavior, ataxia, paralysis, altered vocalization, and seizures. Progression to death is rapid. There are currently no known effective rabies antiviral drugs.

Chagas disease is currently endemic and also predicted to be at increased transmission risk under future climate change scenarios. Similarly, an expansion of areas in the United States at increased risk for Chagas disease transmission is also expected over the next several decades under climate chan...ge scenarios. Of particular interest is the predicted northern shift of triatomine species to central regions of the United States with historically unsuitable climates for T. cruzi vectors. The weight of evidence regarding the influences climate change may pose on T. cruzi vector species distributions demonstrates the sensitivity of Chagas disease transmission to future climate variability. In order to advance forecasts for the impact climate change may have on Chagas disease transmission in the Americas, it is imperative to
further develop, utilize, and perhaps combine predictive species distribution modeling approaches that integrate accurate, long term data on climate variables, vector species distributions, Chagas disease incidence, as well as other socio-ecological variables.

Battling neglected tropical diseases (NTDs) is not easy for a number of reasons. The microbial world is mobile and the targets keep changing. This book reflects on a 15-year battle--one that is still continuing--against five tropical diseases that have been long neglected yet take a heavy toll in de...ath and human suffering today. It introduces some of the protagonists involved--patients in remote villages, health workers, community leaders, district and health ministry officials, researchers, donors and agency staff under the leadership of the World Health Organization (WHO). Its goal is to situate NTDs historically, culturally, and scientifically, and to illustrate the efforts taken over the years to end suffering and bring hope to the thousands of people who have been afflicted by these deadly diseases. Helping the WHO in this endeavour goes beyond fighting pathogens. It involves vigilance over a dangerous world and dedication to public health and well-being in a number of respects--from supporting human rights to creating a better environment for all.

El presente informe incluye análisis de consultas informales en cinco de las regiones de la OMS: la Región de África, la Región de las Américas (donde se realizaron consultas separadas para el Caribe y América del Norte, y para América Latina), la Región de Asia Sudoriental, la Región de Eu...ropa y la Región del Mediterráneo Oriental, junto con tres foros en la Región del Pacífico Occidental. Se analizan las similitudes generales, los matices regionales y las prioridades planteadas en las seis regiones de la OMS para la participación significativa de las personas con experiencias vividas.
El presente informe es la segunda publicación de la serie «De la intención a la acción», un conjunto de recursos destinados a mejorar la limitada base de evidencia sobre el impacto de la participación significativa y abordar la falta de enfoques normalizados sobre cómo hacer operativa esta participación. La serie «De la intención a la acción» pretende llevar esto a cabo proporcionando una plataforma desde la que las personas con experiencias vividas, y los defensores de organizaciones e instituciones, puedan compartir soluciones, retos y prácticas prometedoras relacionadas con esta agenda transversal. La serie «De la intención a la acción» también tiene como objetivo proporcionar poderosas historias, inspiración y evidencia para la 4.ª Reunión de Alto Nivel de las Naciones Unidas sobre las ENT que se celebrará en 2025 y la consecución de los Objetivos de Desarrollo Sostenible (ODS) de las Naciones Unidas para 2030.

Human African trypanosomiasis (HAT), also called sleeping sickness, is a parasitic infection that almost invariably progresses to death, unless treatment is provided. HAT caused devastating epidemics during the 20th century. Thanks to sustained and coordinated efforts during the past 15 years the nu...mber of reported cases has fallen to a historic low. Fewer than 3,000 cases were reported in 2015, and the disease is targeted for elimination by the World Health Organization. Despite recent success, HAT still poses a heavy burden on the rural communities where this highly focal disease occurs, most notably in Central Africa. Since patients are also reported from non-endemic countries outside Africa, HAT should be considered in differential diagnosis for all travellers, tourists, migrants and expatriates who have visited or lived in endemic areas. In the absence of a vaccine, disease control relies on case detection and treatment, and vector control. Available drugs are sub-optimal, but ongoing clinical trials give hope for safer and simpler treatments.

Development finance institutions owned by European governments and the World Bank Group are spending hundreds of millions of dollars on expensive for-profit hospitals in the Global South that block patients from getting care, or bankrupt them, with some even imprisoning patients who cannot afford th...eir bills. At the height of the COVID-19 pandemic, some of these same hospitals denied entry to patients suffering from the virus or sold intensive care beds at eyewatering prices to the highest bidder. These development institutions have woefully inadequate safeguards, invest via a complex web of tax-avoiding financial intermediaries, and offer little to zero evidence on the impacts their investments are having. Oxfam is calling on rich-country governments and the World Bank Group to immediately halt their spending on for-profit private healthcare, and for an urgent independent investigation to be conducted into all active and historic investments.

Prior research has considered donor funding for developing world health by recipient and donor country but not by disease. Examining funding by disease is critical since diseases may be in competition with one another for priority and donors may be making allocation decisions in ways that do not cor...respond to developing world need. In this study I calculate donor funding for 20 historically high-burden communicable diseases for the years 1996 to 2003 and examine factors that may explain variance in priority levels among diseases. I consider funding for developing world health from 42 major donors, classifying grants according to the communicable disease targeted. Data show that funding does not correspond closely with burden. Acute respiratory infections comprise more than a quarter of the burden among these diseases but receive less than 3% of direct aid. Malaria also stands out as a high-burden neglected disease.

WHO convened the fifth stakeholders meeting on the elimination of HAT due to infection with Trypanosoma brucei gambiense (g-HAT) and Trypanosoma brucei rhodesiense (r-HAT) in Geneva, Switzerland, on 7–9 June 2023. The meeting was held again in person after the coronavirus disease (COVID-19) pandem...ic and jointly for both forms of the disease. The previous meetings on g-HAT held in 2014, 2016 and 2018, as well as on r-HAT in 2015, 2017 and 2019, and jointly for g-HAT and r-HAT in 2021 (8) reinforced the partnership and commitment for HAT elimination and structured the mechanisms of collaboration within the WHO network for HAT elimination. The network includes NSSCPs, groups developing new tools, international and nongovernmental organizations involved in disease control, and donors.
Fewer than 1000 cases of HAT annually have been reported over the past 5 years, which is a historic achievement. The area at risk has been substantially reduced. The elimination of HAT as a public health problem at the global level has been achieved.
The new road map for neglected tropical diseases (NTDs) 2021−2030 (“the road map”) with the target to interrupt the transmission of g-HAT requires the strengthened and sustained efforts of all stakeholders, national authorities and partners, under WHO coordination. It will take disproportionally high efforts and innovative strategies to find the last cases of g-HAT and neutralize its transmission. Given the limited resources and other competing public health priorities, this is a challenge that requires our joint commitment.
