The purpose of Salud Everywhere
Salud Everywhere was born out of a real need. When I started working in this sector, no resource in Spanish brought together, in a rigorous and accessible way, the essentials of public health in international cooperation and humanitarian action. After more than fifteen years working in the field, in 2024 I decided to create it myself, guided by the following principles:
- To be a reference learning resource on public health in development cooperation and humanitarian action, with essential information in both Spanish and English, useful for students, teachers, and professionals in the sector.
- To provide essential information with a critical and scientifically rigorous approach.
- To be completely free and open in its access and use, with no need for identification, registration, or course enrolment.
- To be continuously updated, incorporating the best scientific evidence, technical guidelines, and knowledge as it is produced.
- To be written by a person and aimed at people, allowing them to expand their opportunities for in-depth exploration and learning through artificial intelligence tools used in a responsible and ethical manner.
Salud Everywhere is written by a person, not by an artificial intelligence
To write the bibliographic reviews behind most of Salud everywhere's pages, I research extensively. To identify sources, I draw on many of the resources I already know from my day-to-day professional practice, as well as Google and Google Scholar.
To analyze the sources, I read them, which in 2026 seems revolutionary. I also use AI tools such as NotebookLM to explore some ideas more quickly, seek clarification or identify areas of interest in lengthy reports, but restricting its use to the sources I have selected.
Next, I personally write my texts in Spanish, my native language, with my own words.
On occasion, I review my already-written texts with the help of NotebookLM or Claude, asking it to help me identify errors or inconsistencies against the reference sources.
I use TranslatePress and Claude to translate my texts into English. I personally proofread the translations as carefully as I can, and I sometimes make changes to them myself.
I use Claude for coding and SEO. It helps me develop Chrome extensions and small PHP tools, troubleshoot web design issues with CSS, and refine some titles, meta descriptions, and summaries for hub and sub-hub sections.
How to use this resource
Salud Everywhere is completely free to access: there is no need to register or install anything, and it all consists of text and images on open web pages, accessible from any browser, on desktop or mobile, and designed to work on slow connections too. There are no paywalls and no limit on the number of articles.
The content is organised in three levels: thematic hubs, sub-hubs that group pages by topic, and the content pages. You can navigate through the menu, through the side index on each page, or with the search function. Everything is available in Spanish and English, with a language selector in the top bar.
I publish under a Creative Commons Attribution-ShareAlike 4.0 licence (CC BY-SA 4.0): you may copy, translate, adapt and reuse the content, including for commercial purposes, provided you cite the source and share it under the same licence.
Substantive claims are supported by cited, verifiable sources.
Responsible use of content and images
Salud Everywhere explains how health in humanitarian action is understood and organised. It is educational material: it does not replace national protocols, your organisation's guidelines or the judgement of a qualified professional, and it should not be used to make decisions about individual patients.
Everything is based on identifiable, cited sources, such as the Sphere Handbook or the Core Humanitarian Standard, WHO and United Nations agency guidance, evaluations, scientific articles and peer-reviewed literature. Where the evidence is weak or comes from an interested party, I say so in the text.
All photographs are my own, except in a few cases where indicated. I do not publish images of patients or of people in situations of manifest vulnerability, nor images that could identify individuals or locations in conflict settings, nor images that appeal to pity, following the spirit of the humanitarian sector's codes of conduct on images.
The site also accepts no user-generated content: no comments, no forums, no file uploads. Everything is my own work and I review it before publishing.
