The chapter Dementia in Latin America and the Caribbean: Prevalence, Incidence, Impact, and Trends over Time, is part of the publication series titled “Decade of Healthy Aging: situation and challenges”. This document aims to provide an outline
...
of the current situation in Latin America and the Caribbean in respect of the prevalence and incidence of dementia and its impact on the health status of older people. As dementia is a significant global health problem which also has social and economic impacts this document highlights the importance of monitoring dementia in the region. The document evidences that dementia is one of the main contributors to dependence and disability in older people in Latin America and the Caribbean and, although its prevalence and incidence increase exponentially with age, it is not part of normal aging. Alzheimer’s disease is the most common dementia, and there is no cure for this condition, but with timely diagnosis is possible to ameliorate symptoms. It is important to assess what are the needs of people leaving with dementia and their families and to integrate dementia risk reduction strategies in pre-existing strategies for other non-communicable diseases. As shown in the report, despite the huge burden dementia is still underdiagnosed, and it is fundamental to better monitor its prevalence, incidence and the different societal impact that dementia can have. For that, it is crucial to promote the use of harmonized methodologies to address this information in a broader number of studies and countries in the region. This can contribute to the generation of direct actions to decrease dementia risk and lead to healthier lives for people with dementia and their families.

The biennium 2020–2021 has revealed more clearly than ever the need for a strong, credible and independent WHO on the world stage. The coronavirus disease (COVID-19) crisis has demonstrated the fundamental importance of the global detection, response and coordination roles that only WHO can play a

cross all Member States. At the same time, the challenges to global health systems and the pressure to ensure equal access to quality health care and the best health possible for all have mounted. The triple billion targets of the Thirteenth General Programme of Work, 2019–2023 remain relevant. The work of WHO in all contexts has never been more critical. However, as several Member States have pointed out, the COVID-19 pandemic has highlighted the discrepancy between what the world expects of WHO and what it is able to deliver with the resources/capacity it has at its disposal. Sustainable financing is thus a key challenge for the Organization that must be addressed as part of the lessons learned from the current COVID-19 pandemic. Member States discussed this issue in detail during the Seventy-third World Health Assembly and their conclusions were reflected in resolution WHA73.1 (2020). The topic of adequate funding is not new. However, discussions on the matter have, to date, remained rather abstract. Building on previous discussions and taking account of lessons learned, the WHO Secretariat would like to initiate a process aimed at finding a concrete solution to the sustainable financing of WHO. This document proposes a process through which to arrive at such a decision, including the key stages and timeline.

ant explicit consideration in policies and regulations.
These Guidelines, specifically tailored to small water supplies, build on over 60 years of guidance by the World Health Organization (WHO) on drinking-water quality and safety. They focus on establishing drinking-water quality regulations and standards that are health based and context appropriate; on proactively managing risks through water safety planning and sanitary inspections; and on carrying out independent surveillance. The guidance is intended primarily for decision-makers at national and subnational levels with responsibility for developing regulatory frameworks and support programmes related to these activities. Other stakeholders involved in water service provision will also benefit from the guidance in this document.
Designed to be practical and accessible, these Guidelines offer clear guidance that is rooted in the principle of progressive improvement. State-of-the-art recommendations and implementation guidance are provided, drawn from a comprehensive evidence review and established good practices. Additionally, case examples are provided from countries and areas around the world to demonstrate how the guidance in this publication has been implemented in practice in a wide variety of contexts.
Together with WHO’s 2024 Sanitary inspection packages – a supporting tool for the Guidelines for drinking-water quality: small water supplies, these Guidelines update and supersede WHO’s 1997 Guidelines for drinking-water quality. Volume 3: surveillance and control of community supplies. Key changes to this updated publication include a greater focus on preventive risk management and a broader range of small water supplies covered, including those managed by households, communities and professional entities.

Terminology used to describe the transmission of pathogens through the air varies across scientific disciplines, organizations and the general public. While this has been the case for decades, during the coronavirus disease (COVID-19) pandemic, the terms ‘airborne’, ‘airborne transmission’ a
...
nd ‘aerosol transmission’ were used in different ways by stakeholders in different scientific disciplines, which may have contributed to misleading information and confusion about how pathogens are transmitted in human populations.
This global technical consultation report brings together viewpoints from experts spanning a range of disciplines with the key objective of seeking consensus regarding the terminology used to describe the transmission of pathogens through the air that can potentially cause infection in humans.
This consultation aimed to identify terminology that could be understood and accepted by different technical disciplines. The agreed process was to develop a consensus document that could be endorsed by global agencies and entities. Despite the complex discussions and challenges, significant progress was made during the consultation process, particularly the consensus on a set of descriptors to describe how pathogens are transmitted through the air and the related modes of transmission. WHO recognizes the important areas where consensus was not achieved and will continue to address these areas in follow-up consultations.

ngunya, scrub typhus and bacterial infections often present with febrile syndromes that mimic or co-exist with SARS-CoV-2 infection, complicating diagnosis and treatment. This document provides guidelines for preventing, diagnosing and managing such co-infections. A high level of suspicion is essential during the monsoon and post-monsoon seasons, taking into account region-specific disease prevalence. While the WHO's case definition for SARS-CoV-2 is broad and sensitive, the need for parallel testing for co-infections, in accordance with the protocols of the MoHFW, ICMR, NVBDCP and NCDC, is necessitated by overlapping clinical features. Ensuring the availability of reliable rapid diagnostic kits and applying integrated clinical and laboratory approaches are crucial to improving patient outcomes in the context of concurrent infections.
