El desarrollo de inmunidad a un patógeno por infección natural es un proceso de varias etapas que suele producirse a lo largo de una o dos semanas. El organismo responde a una infección vírica de forma inmediata a través de una respuesta innata no específ...ica, en la que los macrófagos, los neutrófilos y las células dendríticas frenan el avance del virus y pueden incluso evitar que este provoque síntomas. A esta respuesta no específica le sigue una respuesta adaptativa en la que el organismo genera anticuerpos que se unen específicamente al virus. Estos anticuerpos son las proteínas denominadas inmunoglobulinas. El organismo también genera linfocitos T que reconocen y eliminan las células infectadas por el virus: es lo que se conoce como inmunidad celular. Esta respuesta adaptativa combinada puede eliminar el virus del organismo y, si la respuesta es suficientemente intensa, puede evitar el agravamiento de la enfermedad o la reinfección por el mismo virus. Este proceso se mide a menudo a través de la presencia de anticuerpos en la sangre.

Guinea’s 450 megawatt Souapiti dam, scheduled to begin operating in September 2020, is the most advanced of several new hydropower projects planned by the government of President Alpha Condé. Guinea’s government believes that hydropower can significantly increase access to electricity in a cou...ntry where only a fraction of people have reliable access to power.Souapiti’s output, however, has a human cost. The dam’s reservoir will ultimately displace an estimated 16,000 people from 101 villages and hamlets. The Guinean government had moved 51 villages by the end of 2019 and said it planned to conduct the remaining resettlements within a year. Forced off their ancestral homes and farmlands, and with much of their land already, or soon to be flooded, displaced communities are struggling to feed their families, restore their livelihoods, and live with dignity.

Policy Brief 2 June 2020
The COVID-19 pandemic is a health and human crisis threatening the food security and nutrition of millions of people around the world. Hundreds of millions of people were already suffering from hunger and malnutrition before the virus hit and, unless immediate action is tak...en, we could see a global food emergency. In the longer term, the combined effects of COVID-19 itself, as well as corresponding mitigation measures and the emerging global recession could, without large-scale coordinated action, disrupt the functioning of food systems. Such disruption can result in consequences for health and nutrition of a severity and scale unseen for more than half a century.

Whole-genome sequencing (WGS) provides a vast amount of information and the highest possible resolution for pathogen subtyping. The application of WGS for global surveillance can provide information on the early emergence and spread of AMR and further inform timely policy development on AMR control.... Sequencing data emanating from AMR surveillance may provide key information to guide the development of rapid diagnostic tools for better and more rapid characterization of AMR, and thus complement phenotypic methods. This document addresses the applications of WGS for AMR surveillance, including the benefits and limitations of current WGS technologies
