Environmental exposure to active pharmaceutical ingredients (APIs) can have negative effects on the health of ecosystems and humans. While numerous studies have monitored APIs in rivers, these employ different analytical methods, m...easure different APIs, and have ignored many of the countries of the world. This makes it difficult to quantify the scale of the problem from a global perspective. Furthermore, comparison of the existing data, generated for different studies/regions/continents, is challenging due to the vast differences between the analytical methodologies employed. Here, we present a global-scale study of API pollution in 258 of the world’s rivers, representing the environmental influence of 471.4 million people across 137 geographic regions. Samples were obtained from 1,052 locations in 104 countries (representing all continents and 36 countries not previously studied for API contamination) and analyzed for 61 APIs. Highest cumulative API concentrations were observed in sub-Saharan Africa, south Asia, and South America. The most contaminated sites were in low- to middle-income countries and were associated with areas with poor wastewater and waste management infrastructure and pharmaceutical manufacturing. The most frequently detected APIs were carbamazepine, metformin, and caffeine (a compound also arising from lifestyle use), which were detected at over half of the sites monitored. Concentrations of at least one API at 25.7% of the sampling sites were greater than concentrations considered safe for aquatic organisms, or which are of concern in terms of selection for antimicrobial resistance. Therefore, pharmaceutical pollution poses a global threat to environmental and human health, as well as to delivery of the United Nations Sustainable Development Goals.

The World Health Organization (WHO) endorses the use of population-based prevalence surveys for estimating the prevalence of trachoma. In general, the prevalence of TF in children aged 1–9 years and the prevalence of TT in adults aged ≥ 15 years are measured at the same time in any district bein...g surveyed. This was the approach of the Global Trachoma Mapping Project, which undertook baseline surveys in > 1500 districts worldwide in order to provide the data required to start interventions where needed.
The survey design recommended by WHO is a two-stage cluster random sample survey, which uses probability proportional to size sampling to select 20–30 villages, and random, systematic or quasi-random sampling to select 25–30 households in each of those villages. In most surveys, everyone aged ≥ 1 year living in selected households is examined.

The guidance in this publication consists of generic definitions and methodologies for the characterization of extreme weather and climate events. This publication contribute to ensuring consistent exchange of information that underpins the WMO State of the Climate Reports, Climate Watches, climate ...change studies and other emerging applications.
The purpose of the present guidelines is not to change the practice at the national level. Instead, it provides guidance for generic definitions, which are useful in contributing to WMO State of the Climate reports, climate watches, climate change studies and other emerging applications, including the recently adopted methodology for cataloguing hazardous events (WMO-CHE). These applications require regional and/or international exchange of information on extreme events.

Worldwide, over 6 million people are infected with Trypanosoma cruzi, the pathogen that causes Chagas disease (CD). In the Americas, CD creates the greatest burden in disability-adjusted life years of any parasitic infection. In Co...lombia, 437 000 people are infected with T. cruzi, of whom 131 000 suffer from cardiomyopathy. Colombia’s annual costs for treating patients with advanced CD reach US$ 175 016 000. Although timely etiological treatment can significantly delay or prevent development of cardiomyopathy—and costs just US$ 30 per patient—fewer than 1% of people with CD in Colombia and elsewhere receive it.

Ending Cholera—A Global Roadmap to 2030 operationalises the new global strategy for cholera control at the country level and provides a concrete path toward a world in which cholera is no longer a threat to public health
En el Plan estratégico de preparación y respuesta frente a la COVID-19, del 2021, la Organización Panamericana de la Salud invita a las autoridades nacionales a actualizar los planes nacionales para la COVID-19 a fin de incorporar las enseñanzas extraídas a lo largo del 2020, de prever los reto...s que habrá en el 2021 y de prepararse para ellos, incluida la preparación de todos los sistemas de salud para introducir de manera segura y equitativa nuevas herramientas para combatir la COVID-19, como las vacunas. En esta Orientación para la planificación operativa, que acompaña al plan estratégico de preparación y respuesta para el 2021, se proponen medidas prácticas de alto nivel en cada uno de los diez pilares de la preparación y la respuesta, que los países pueden adaptar según corresponda y ejecutar a escala nacional y subnacional para alcanzar los objetivos estratégicos del plan.
