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 organi...smo responde a una infección vírica de forma inmediata a través de una respuesta innata no específica, 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.

Rabies remains an under-reported neglected zoonosis with a case-fatality rate of almost 100% in humans and animals. Dog-mediated human rabies causes tens of thousands of human deaths annually despite being 100% preventable. More than 95% of human ca...ses are caused by the bite of a rabies-infected dog. Dog-mediated human rabies disproportionately affects rural communities, particularly children, and economically disadvantaged areas of Africa and Asia, where awareness of the disease and access to appropriate post-exposure prophylaxis (PEP) can be limited or nonexistent.

his document, a first of its kind, clearly sets out the standards for rehabilitation and provides guidance on building or strengthening the capacity of EMTs in this area.The importance of early rehabilitation for functional outco...mes is well documented. Rehabilitation needs can persist far beyond the departure of EMTs; therefore, close, supportive collaboration must be established with local services. Emergency response presents an opportunity to rebuild devastated health systems and build local rehabilitation capacity. This document emphasizes the importance of aligning practices to the local context and maximizing opportunities for training and mentorship. The minimum standards and recommendations described will result in faster access of patients to rehabilitation services and equipment and a better transition between EMTs and local health facilities.

Although Shiga toxin-producing Escherichia coli (STEC) have been isolated from a variety of food production animals, they are most commonly associated with ruminants from which we derive meat and milk. Because of the widespread and diverse nature of... ruminant-derived food production, coupled with the near ubiquity of STEC worldwide, there is no single definitive solution for controlling STEC that will work alone or in all situations. Instead, the introduction of multiple interventions applied in sequence, as a “multiple-hurdle scheme” at several points throughout the food chain (including processing, transport and handling) will be most effective.
This report summarizes the review and evaluation of interventions applied for the control of STEC in cattle, raw beef and raw milk and raw milk cheese manufactured from cows’ milk, and also evaluates available evidence for other small ruminants, swine and other animals. The information is presented from primary production, to the end of processing, providing the reader with information on the currently available interventions based on the latest scientific evidence.
This work was undertaken to support the development of guidelines for the control of STEC in beef, raw milk and cheese produced from raw milk by the Codex Committee on Food Hygiene (CCFH).

Snakebite envenoming affects millions of people worldwide annually and is a significant source of mortality. Preventing and treating the problem is complex and requires collaboration among the fields of public health, medicine, ecology, and laborato...ry science. After being removed from the category A neglected tropical disease (NTD) list in 2013, snakebite envenoming was reinstated in 2017 in response to antivenom shortages and advocacy from researchers and international NGOs. In 2019, the World Health Organization (WHO) set a target to halve the number of deaths and cases of snakebite envenoming by 2030.

The United States Agency for International Development (USAID) Bureau for Democracy, Conflict, and Humanitarian Assistance Office of U.S. Foreign Disaster Assistance (DCHA/OFDA) requested Food and Nutrition Technical Assistance II Project (FANTA-2) assistance to review Community-Based Management of ...Acute Malnutrition (CMAM) in four West African countries—Burkina Faso, Mali, Mauritania, and Niger—to help identify DCHA/OFDA 2010 and 2011 program priorities, including where DCHA/OFDA investment should be directed to support CMAM. The goal was to review CMAM program implementation and its integration into national health systems to provide DCHA/OFDA a status report for each country; draw lessons learned; and make recommendations on challenges, promising practices, gaps, and priority areas for DCHA/OFDA support during 2010 and 2011. The review was intended for DCHA/OFDA program planning purposes and also potentially as an advocacy tool to guide other donors in planning CMAM support in the region. After all four countries have been reviewed, FANTA-2 will develop a synthesis report. The current document presents a summary report on CMAM in Burkina Faso only.
