The health impacts of climate change are no longer a distant threat. They are being felt here and now and becoming more extreme.
To address these threats, the WHO Asia-Pacific Centre for Environment and Health in the Western Pacific Region (ACE) was established in 2019 through a partnership with ...the Seoul Metropolitan Government, the Ministry of Climate, Energy and Environment of the Republic of Korea and the World Health Organization (WHO).
The Centre’s mission is to strengthen cooperation and drive action where environment and health meet. This focus on environmental health has created a strong foundation for system-wide change.
This strategic plan builds directly on that work. Over the next five years, the Centre will expand its reach, supporting countries to take practical, systems-based action that ensures healthier people, healthier environments and a healthier planet.

PHSM are vital in reducing the risk and scale of infectious disease transmission and lowering hospitalization and deaths. Examples include contact tracing, quarantine and isolation, mask use, ventilation, school or workplace measures, mobility restrictions and travel requirements.
While these mea...sures are essential, decision-making on PHSM becomes particularly complex during rapidly evolving health emergencies, with incomplete information and under significant public and political pressure, especially when the pathogen is novel or poorly understood. In such contexts, guidance needs to be agile and responsive, developed and adapted based on emerging evidence and shifting epidemiological patterns. Decision-makers are frequently confronted with difficult trade-offs, having to balance measures that are:
─ effective but socially disruptive;
─ cost-effective but logistically burdensome;
─ beneficial for public health but economically disruptive; or
─ practical but inequitable or unethical

The Best Buys for Disease Elimination is a practical, evidence-based guide to the most effective actions for countries to implement in order to eliminate communicable diseases. The guide highlights the efficient use of resources and prioritizing populations in vulnerable situations.
“The Region... of the Americas is advancing steadily towards the elimination of communicable diseases,” said Dr. Jarbas Barbosa, PAHO Director. “To achieve this, it is necessary to increase and sustain high vaccination coverage, engage communities to expand access to diagnosis and treatment, strengthen surveillance, and bring integrated services to marginalized communities, incarcerated populations, and those living in informal settlements,” he added.
For each disease and condition included in the Elimination Initiative, the Best Buys are presented as one-page documents with clear, accessible information. Each Best Buy summarizes expected impact goals, disease elimination targets, key operational indicators, and priority interventions that have proven to be cost-effective in different contexts.

On 4 September 2025, the Ministry of Health of the Democratic Republic of the Congo (DRC) declared an outbreak of Ebola Virus Disease (EVD) in Kasai Province, following confirmation of Zaire ebolavirus by the National Institute of Biomedical Research (INRB) in Bulape and Mweka Health Zones. As of 19... September, there have been 48 total cases (38 confirmed, 10 probable) with 31 deaths (21 confirmed, 10 probable) and a CFR of 64.5%. Among laboratory confirmed cases, 16 deaths were recorded (CFR: 45.7%). Four deaths occurred among health workers, underscoring the risk of nosocomial transmission. Most cases (39.7%) are among adults aged 20 years and above, in a densely populated, remote, and under-resourced area.
The outbreak is driven by multiple risk factors, including transmission in health facilities with limited infection prevention and control (IPC) measures and personal protective equipment (PPE), incomplete contact tracing, delayed detection, and unsafe burial practices. High population mobility between Bulape and Tshikapa, reliance on traditional healers, and the concurrent mpox outbreak are further straining the fragile health system and increasing the risk of geographic spread.

This plan, approved by the Organization’s 62nd Directing Council, was shaped by extensive consultations with countries and stakeholders, and commits to transformative health outcomes over the next six years, tackling noncommunicable diseases (NCDs), mental health, health security, fragmented healt...h systems and services, and the elimination of communicable diseases, amongst others.
“The COVID-19 pandemic taught us that the Region of the Americas is stronger when we work together,” said Dr. Jarbas Barbosa, PAHO Director. “This Strategic Plan harnesses our collective strength to build resilient health systems, reduce disease burden, and improve health and well-being for all across the Americas.”
The plan builds on lessons from the COVID-19 pandemic, which exposed gaps in health systems while highlighting the power of joint action. It targets measurable impacts in countries, such as reducing maternal mortality, reversing rising suicide rates, and eliminating diseases like leprosy and Chagas.

The WHO handbook “Epidemiological Data Analysis for the Early Warning Alert and Response Network (EWARN) in Humanitarian Emergencies” explains how to collect, analyse, interpret, and share health data during crises such as conflicts or natural disasters. It is a practical guide for health and su...rveillance officers to detect disease outbreaks early and guide quick public health responses. The document outlines steps for managing data at different levels (local, regional, national), analysing disease trends by time, place, and person, and using indicators to monitor outbreak risks. It also provides methods for interpreting and communicating results clearly to decision-makers to support effective health interventions in emergencies.

A community health worker (CHW) model can promote HIV prevention and treatment behaviors,
especially in highly mobile populations. In a fishing community in Rakai, Uganda, the Rakai
Health Sciences Program implemented a communit...y health worker HIV intervention called Health
Scouts. The situated Information, Motivation, and Behavioral Skills (sIMB) framework informed
the design and a qualitative evaluation of the intervention. We interviewed 51 intervention
clients and coded transcripts informed by sIMB framework dimensions.

Building on the WHO guidelines for disclosure to children up to age 12 in 2011, this implementation guidance provides evidence on existing interventions that support children and adolescents living with HIV in the process of disclosure. It includes interventions that focuses on safe disclosure, as w...ell as supporting children and adolescents with onwards disclosure. Specifically, this brief collates existing interventions via a scoping review; assesses key interventions through a realist evaluation lens, identifying what works, for whom, and in what contexts; and highlights emerging considerations, key gaps, and key actions.

The document provides a standardized protocol for evaluating the Early Warning Alert and Response Network (EWARN), a surveillance system used during humanitarian emergencies when regular national health surveillance may be disrupted. The purpose of EWARN is to detect outbreaks of communicable diseas...es early and enable rapid public health response. The guidance explains how the system should be assessed in terms of its structure, implementation, effectiveness, and usefulness. It outlines the key steps of evaluation: preparation, system description, data collection, and post-evaluation reporting. The protocol highlights common challenges observed in previous EWARN implementations, such as delays in establishing the system, limited data quality, weak outbreak response, and lack of clear transition plans back to routine surveillance systems. It emphasizes the need to evaluate both weekly disease reporting and alert verification processes, and to review attributes such as simplicity, data quality, timeliness, sensitivity, and stability. The document also provides templates for interviews, data review forms, and laboratory assessment, as well as guidance on conducting remote evaluations when access is limited. The overall goal of the protocol is to ensure that EWARN functions effectively to detect and respond to outbreaks and that practical recommendations are developed to improve the system’s performance and sustainability in emergency settings.
