The United Nations Children's Fund (UNICEF), the International Organization for Migration (IOM), Georgetown University, and the United Nations University have today launched new guidelines to provide the first-ever global policy framework that will help protect, include, and empower children on the ...move in the context of climate change.
The Guiding Principles for Children on the Move in the Context of Climate Change provides a set of 9 principles that address the unique and layered vulnerabilities of children on the move both internally and across borders as a result of the adverse impacts of climate change. Currently, most child-related migration policies do not consider climate and environmental factors, while most climate change policies overlook the unique needs of children.
The guidelines note that climate change is intersecting with existing environmental, social, political, economic, and demographic conditions contributing to people’s decisions to move. In 2020 alone, nearly 10 million children were displaced in the aftermath of weather-related shocks. With around one billion children – nearly half of the world’s 2.2 billion children – living in 33 countries at high risk of the impacts of climate change, millions more children could be on the move in the coming years.
Developed in collaboration with young climate and migration activists, academics, experts, policymakers, practitioners, and UN agencies, the guiding principles are based on the globally ratified Convention on the Rights of the Child and are further informed by existing operational guidelines and frameworks.
Recommendations for safeguarding the rights and well-being of children regardless of their location or migration status.
The guiding principles provide national and local governments, international organizations and civil society groups with a foundation to build policies that protect children’s rights. The organizations and institutions are calling on governments, local and regional actors, international organizations, and civil society groups to embrace the guiding principles to help protect, include, and empower children on the move in the context of climate change.

Interim Guidance, published 11 January 2021.
The cold chain is necessary to prevent damage to vaccines caused by heat exposure. However, improper use of cold chain equipment may cause damage to freeze-sensitive vaccines (i.e. those vaccines containing alum adjuvant or oil-emulsion adjuvant). Studie...s conducted in several countries with hot and cold climates show frequent occurrences of sub-zero temperatures in the cold chain. The most common cause of exposure to freezing temperature is the failure to correctly condition ice packs prior to transport. Vaccines that are inadvertently frozen lose potency, increase wastage rates and increase the risk of adverse events following immunization (AEFI). Vaccine carriers protect vaccine potency during immunization sessions and transport to outreach sites. This guidance document is intended to help inform which type of vaccine carrier to select based on local context, to maintain vaccine quality, especially at service delivery points.

Addressing comorbidities and risk factors for tuberculosis (TB) is a crucial component of the World Health Organization (WHO)’s End TB Strategy. This WHO operational handbook on tuberculosis. Module 6: tuberculosis and comorbidities aims to support countries in scaling up people-centred care, base...d on the latest WHO recommendations on TB and key comorbidities, and drawing upon additional evidence, best practices and inputs from various experts and stakeholders obtained during WHO processes. It is intended for use by people working in ministries of health, particularly TB programmes and the relevant departments or programmes responsible for comorbidities and health-related risk factors for TB such as HIV, diabetes, undernutrition, substance use, and tobacco use, as well as programmes addressing mental health and lung health. This operational handbook is a living document and will include a separate section for each of the key TB comorbidities or health-related risk factors. The third edition includes guidance for HIV-associated TB, mental health conditions and diabetes, which are three conditions strongly associated with TB and which result in higher mortality, poorer TB treatment outcomes and negatively impact health-related quality of life. The operational handbook aims to facilitate early detection, proper assessment and adequate management of people affected by TB and comorbidities. Full implementation of this guidance is expected to have a significant impact on TB treatment outcomes and health-related quality of life for people affected by TB.

Introduction: Considering the global prevalence of coronavirus disease 2019 (COVID-19), a vaccine is being developed to control the disease as a complementary solution to hygiene measures—and better, in social terms, than social distancing. Given that a vaccine will eventually be produced, informa...tion will be needed to support a potential campaign to promote vaccination.
Objective: The aim of this study was to determine the variables affecting the likelihood of refusal and indecision toward a vaccine against COVID-19 and to determine the acceptance of the vaccine for different scenarios of effectiveness and side effects.
Materials and Methods: A multinomial logistic regression method based on the Health Belief Model was used to estimate the current methodology, using data obtained by an online anonymous survey of 370 respondents in Chile.
Results: The results indicate that 49% of respondents were willing to be vaccinated, with 28% undecided or 77% of individuals who would potentially be willing to be inoculated. The main variables that explained the probability of rejection or indecision were associated with the severity of COVID-19, such as, the side effects and effectiveness of the vaccine; perceived benefits, including immunity, decreased fear of contagion, and the protection of oneself and the environment; action signals, such as, responses from ones' family and the government, available information, and specialists' recommendations; and susceptibility, including the contagion rate per 1,000 inhabitants and relatives with COVID-19, among others. Our analysis of hypothetical vaccine scenarios revealed that individuals preferred less risky vaccines in terms of fewer side effects, rather than effectiveness. Additionally, the variables that explained the indecision toward or rejection of a potential COVID-19 vaccine could be used in designing public health policies.
Conclusions: We discovered that it is necessary to formulate specific, differentiated vaccination-promotion strategies for the anti-vaccine and undecided groups based on the factors that explain the probability of individuals refusing or expressing hesitation toward vaccination.

Africa’s health sector is facing an unprecedented financing crisis, driven by a sharp decline of 70% in Official Development Assistance (ODA) from 2021 to 2025 and deep-rooted structural vulnerabilities. This collapse is placing immense pressure on Africa’s already fragile health systems as ODA ...is seen as the backbone of critical health programs: pandemic preparedness, maternal and child health services, disease control programs are all at
risk, threatening Sustainable Development Goal 3 and Universal Health Coverage. Compounding this is Africa’s spiraling debt, with countries expected to service USD 81 billion by 2025—surpassing anticipated external financing inflows—further eroding fiscal space for health investments. Level of domestic resources is low. TThe Abuja Declaration of 2001, a pivotal commitment made by African Union (AU) member states, aimed to reverse this trend by pledging to allocate at least 15% of national budgets to the health sector. However, more than two decades later, only three countries—Rwanda, Botswana, and Cabo Verde—have
consistently met or exceeded this target (WHO, 2023). In contrast, over 30 AU member states remain well below the 10% benchmark, with some allocating as little as 5–7% of their national budgets to health.
In addition, only 16 (29%) of African countries currently have updated versions of National Health Development Plan (NHDP) supported by a National Health Financing Plan (NHFP). These two documents play a critical role in driving internal resource mobilisation. At the same time, public health emergencies are surging, rising 41%—from 152 in 2022 to
213 in 2024—exposing severe under-resourcing of health infrastructure and workforce. Recurring outbreaks (Mpox, Ebola, cholera, measles, Marburg…) alongside effects of climate change and humanitarian crises in Eastern DRC, the Sahel, and Sudan, are overwhelming systems stretched by chronic underfunding. The situation is worsened by Africa’s heavy dependency with over 90% of vaccines, medicines, and diagnostics being externally sourced—leaving countries vulnerable to global supply chain shocks. Health worker shortages persist, with only 2.3 professionals
per 1,000 people (below the WHO’s recommended 4.45), and fewer than 30% of systems are digitized, undermining disease surveillance and early warning. Without decisive action, Africa CDC projects the continent could reverse two decades of health progress, face 2 to 4 million additional preventable deaths annually, and a heightened risk of a pandemic emerging from within. Furthermore, 39 million more
Africans could be pushed into poverty by 2030 due to intertwined health and economic shocks. This is not just a sectoral crisis—it is an existential threat to Africa’s political, social, and economic resilience, and global stability. In response, African leaders, under Africa CDC’s stewardship, are advancing a comprehensive three-pillar strategy centered on domestic resource mobilization, innovative financing, and blended finance.

This study shows the importance of an integrated entomological and medical surveillance for the evaluation of arboviral disease risk, which is a precondition for designing cost-effective vector control programs.
On 17 October 2017, the Ugandan Ministry of Health notified WHO of a confirmed Marburg outbreak of Marburg Virus disease (MVD) in Kween district, Eastern Uganda. The outbreak was officially declared by the Ministry of health on 19 October 2017.
As of 7 November, four cases of MVD have been reported...- two confirmed (dead), one probable (dead) and one suspected. Other patients, previously reported as suspected cases, have since tested negative for the virus.
WHO has been implementing the Emergency Response Plan since 20 October 2017 when the Ministry of Health officially declared the outbreak. The Emergency Response Plan was developed on several assumptions which may now need to be revised.

Parasites & Vectors volume 11, Article number: 264 (2018)
Dengue creates a staggering epidemiological and economic burden for endemic countries. Without a specific therapy and with a commercial vaccine that presents some problems relative to its full effectiveness, initiatives to improve vector... control strategies, early disease diagnostics and the development of vaccines and antiviral drugs are priorities. In this study, we present the probable origins of dengue in America and the trajectories of its spread. Overall, dengue diagnostics are costly, making the monitoring of dengue epidemiology more difficult and affecting physicians’ therapeutic decisions regarding dengue patients, especially in developing countries. This review also highlights some recent and important findings regarding dengue in Brazil and the Americas. We also summarize the existing DENV polymerase chain reaction (PCR) diagnostic tests to provide an improved reference since these tests are useful and accurate at discriminating DENV from other flaviviruses that co-circulate in the Americas. Additionally, these DENV PCR assays ensure virus serotyping, enabling epidemiologic monitoring.

Evidence-based guidelines are one of the most useful tools for improving public health and clinical practice. Their purpose is to formulate interventions based on strong evidence of efficacy, avoid unnecessary risks, use resources efficiently, reduce clinical variability and, in essence, improve hea...lth and ensure quality care, which is the purpose of health systems and services. These guidelines were developed following the GRADE methodology, with the support of a panel of clinical experts from different countries, all convened by the Pan American Health Organization. By responding to twelve key questions about the clinical diagnosis and treatment of dengue, chikungunya, and Zika, evidence-based recommendations were formulated for pediatric, youth, adult, older adult, and pregnant patients who are exposed to these diseases or have a suspected or confirmed diagnosis of infection. The purpose of the guidelines is to prevent progression to severe forms of these diseases and the fatal events they may cause. The recommendations are intended for health professionals, including general, resident, and specialist physicians, nursing professionals, and medical and nursing students, who participate in caring for patients with suspected dengue, chikungunya, or Zika. They are also intended for health unit managers and the executive teams of national arboviral disease prevention and control programs, who are responsible for facilitating the process of implementing these guidelines.

Over the past 50 years, dengue has spread from nine to over a hundred countries, making it the most rapidly spreading vector-borne disease. Yet, dengue continues to have a low profile among policy-makers and donors and does not receive the media attention it deserves. While there is no vaccine or cu...re for dengue, it can be managed and prevented. We need a renewed commitment to integrated programming that includes improved management and diagnosis, increased awareness and community participation in controlling the vector and enhanced environmental sanitation
