Prompt, effective antimalarial treatment, and supportive care can substantially reduce the rate of mortality from severe malaria. However, many children in malaria-endemic countries do not have access to health facilities or a qualified health care provider and do not receive the necessary care in a... timely fashion. Without rapid detection of danger signs and access to effective treatment, including pre-referral treatment that can be administered in the community level, many of these children with severe malaria die.
In situations where there is no immediate access to a health care facility, WHO recommends the administration of a standard dose of an effective antimalarial medicine as pre-referral treatment before referral to a facility at which complete treatment can be administered.
Rectal artesunate is the WHO-recommended pre-referral intervention in situations where artesunate injection are not feasible for children under the age of 6 years with suspected severe malaria. The intervention reduces the risk of death or permanent disability by up to 50% provided the child is referred to a health facility at which complete treatment can be administered.
This field guide is aimed at supporting the effective deployment of RAS as pre-referral treatment of suspected severe malaria in line with the WHO malaria guidelines.

Policy Brief November 2021 Available in English, Spanish and Portuguese
The COVID-19 pandemic has fueled the ongoing antimicrobial resistance (AMR) global crisis due to the increase in the use of antibiotics to treat COVID-19 patients, disruptions to infection prevention and control practices in o...verwhelmed health systems, and diversion of human and financial resources away from monitoring and responding to AMR threats. Moreover, AMR is likely to have caused more COVID-19 deaths, as secondary bacterial infections can worsen the outcome of severe and critical COVID-19 illness. Therefore, it is more urgent than ever to prioritize efforts towards AMR containment and support countries to improve the detection, characterization and rapid response to emerging AMR.

The purpose of the WHO Manual for the Public Health Management of Chemical Incidents is to provide a comprehensive overview of the principles and roles of public health in the management of chemical incidents and emergencies. While this information is provided for each phase of the emergency cycle, ...including prevention, planning and preparedness, detection and alert, response and recovery, it is recognized that the management of chemical incidents and emergencies requires a multi-disciplinary and multi-sectoral approach and that the health sector may play an influencing, complementary or a leadership role at various stages of the management process. The target audience includes public health and environmental professionals, as well as any other person involved in the management of chemical incidents.
WHO and all those involved in the development of the publication hope that the publication will have wide application, especially in developing countries and countries with economies in transition, and that in the future the health sector will be better prepared to acknowledge and fulfill its roles and responsibilities in the management of chemical incidents and emergencies, thereby contributing to the prevention and mitigation of their health consequences.
The publication is also available in French: http://apps.who.int/iris/bitstream/handle/10665/246117/9789242598148-fre.pdf?sequence=1 and in Spanish: http://apps.who.int/iris/bitstream/handle/10665/246118/9789243598147-spa.pdf?sequence=1

The Epidemic Preparedness and Response Plan for Cholera in Syria (November 2015) outlines strategies to prevent, detect, and manage cholera outbreaks in the country, where poor water and sanitation conditions, displacement, and damaged healthcare infrastructure increase the risk of disease spread. T...he plan aims to reduce morbidity and mortality through early detection, rapid response, and coordinated interventions. It is divided into four key phases: the Pre-Epidemic Phase, which includes risk assessment, resource mapping, stockpiling medical supplies, training health workers, and raising community awareness; the Alert Phase, which focuses on surveillance, laboratory confirmation, and mobilization of rapid response teams; the Epidemic Phase, which involves case management, infection control, environmental measures such as water chlorination and improved sanitation, and public awareness campaigns; and the Post-Epidemic Phase, which evaluates the response effectiveness and identifies lessons to improve future preparedness. The plan emphasizes multi-sectoral coordination, strengthening health surveillance, and ensuring timely intervention to control and prevent cholera outbreaks in vulnerable communities.

The Plan of Action for Malaria Elimination 2021-2025 has been developed in consultation with countries and regional partners as a framework of reference to guide the efforts of countries and the contributions of donors and partners towards elimination of the disease in the Americas. The Plan subscri...bes to the goals and pillars of the WHO Global Technical Strategy against Malaria 2016-2030 (GTS), while presenting key elements to address the specific challenges of the Region. The document seeks to guide national plans and promote an inter-programmatic- intersectoral approach, and joint efforts between countries and partners. The Plan is also the reference framework for PAHO technical cooperation in malaria in the period 2021-2025. The goals to be achieved require changes in action against malaria that must occur at the operations level and for which regulatory and policy adjustments are required from the national levels. Thus, the Plan promotes a systematic action of detection, diagnosis and response, which must be massively implemented and monitored programmatically. A main element of change is action aimed at recognizing the need to address key malaria foci in each country with specific, information-based operational solutions. The Plan of Action seeks to promote these changes in malaria programs in the countries and through the interactions among all actors. The model proposed in this plan is based on a cross-functional dialogue and interconnections across the lines of action (SL). Strategic lines 1, 2 and 3, which correspond to the three pillars of the WHO/GTS, complement each other, and are not designed to function independently. The idea of the consolidated supportive elements - strengthened health systems, strategic planning, financing, partnerships, advocacy, and operational research (SL 4) is to provide the platform, operational structures and alliances for the more specific malaria interventions presented in strategic lines 1, 2 and 3.

The One Health (OH) High-Level Expert Panel (OHHLEP) of the Quadripartite Organizations defined OH as an integrated, unifying approach that aims to sustainably balance and optimize the health of people, animals and ecosystems.”
It recognizes the health of humans, domestic and wild animals, plan...ts, and the wider environment (including ecosystems) are closely linked and interdependent [1]. The Tripartite which comprised the Food and Agriculture Organization (FAO) of the United Nations (UN), the World Health Organization (WHO), and the World Organisation for Animal Health (WOAH) later became the Quadripartite organizations when the United Nations Environment Programme (UNEP) joined the OH alliance in 2022. There are Global and Regional Quadripartite Secretariats consisting of officials of headquarters and regional offices, respectively.
Over the years, the Tripartite/Quadripartite organizations and other partner agencies have developed several OH assessment and operational tools to support Member States in assessing their core capacities to achieve compliance with the requirements of international standards such as the International Health Regulations 2005 (IHR), WOAH’s Terrestrial and Aquatic Animal Health Codes, World Trade Organization’s Sanitary and Phytosanitary Measures (WTO-SPS), FAO/WHO Codex standards, etc. Technical areas that the existing tools currently support include progress monitoring, coordination and collaboration mechanisms, and capacity building for prevention, detection, preparedness, and response to health threats emerging at human-animal-environment interface. More OH B operational tools are in the pipeline.

A century after its discovery, Chagas' disease still represents a major public health challenge in Latin America. Moreover, because of growing population movements, an increasing number of cases of imported Chagas' disease have now been detected in non-endemic areas, such as North America and some E...uropean countries. This parasitic zoonosis, caused by Trypanosoma cruzi, is transmitted to humans by infected Triatominae insects, or occasionally by non-vectorial mechanisms, such as blood transfusion, mother to fetus, or oral ingestion of materials contaminated with parasites. Following the acute phase of the infection, untreated individuals enter a chronic phase that is initially asymptomatic or clinically unapparent. Usually, a few decades later, 40-50% of patients develop progressive cardiomyopathy and/or motility disturbances of the oesophagus and colon. In the last decades several interventions targeting primary, secondary and tertiary prevention of Chagas' disease have been attempted. While control of both vectorial and blood transfusion transmission of T cruzi (primary prevention) has been successful in many regions of Latin America, early detection and aetiological treatment of asymptomatic subjects with Chagas' disease (secondary prevention) have been largely underutilised. At the same time, in patients with established chronic disease, several pharmacological and non-pharmacological interventions are currently available and have been increasingly used with the intention of preventing or delaying complications of the disease (tertiary prevention). In this review we discuss in detail each of these issues.

Dengue is a significant public health problem. There are four dengue virus serotypes identified; however, its diagnosis is difficult due to the existence of many viruses, bacteria, and parasites producing the same clinical presentation, being present in the same geographical area and even producing ...coinfections. Therefore, determining whether a person has, had, or is infected with dengue virus is of great importance. In order to do so, direct and indirect laboratory tests have been developed to identify the virus or part of its structure that generally detects the antibody response. These techniques are used for diagnosis, epidemiological studies, monitoring, assessment and production of vaccines and antivirals, etc. They range from the use of cell cultures, animal models, inoculation by insects, and serology tests to the use of detection molecular tests and quantification of genetic material that are described in this chapter herein, a brief explanation of this methodology, its strengths and weaknesses, and its application in the dengue research.
