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.

This country cooperation strategy (CCS) outlines how the World Health Organization (WHO) will work with the Lao People’s Democratic Republic over the next five years (2024–2028), supporting the implementation of the five-year health sector development plans and the Health Sector Reform Strategy ...2021–2030 to attain the Sustainable Development Goals (SDGs) by 2030.
The Lao People’s Democratic Republic experienced substantial economic growth in the 30 years prior to the coronavirus disease (COVID-19) pandemic, contributing to reduced poverty and significant progress toward the SDGs. However, the COVID-19 pandemic brought this development to a halt. It was anticipated that the COVID-19 recovery and the tremendous population growth in recent years would provide opportunities for a shift toward more sustainable and inclusive development in the years ahead. In 2023, however, the contrary was the case. Rural residents, including many ethnic minorities, continued to face marginalization because of limited access to education, health care and economic opportunities.
Despite the challenges of COVID-19 and other disease outbreaks, the country has made significant improvements in health. Nonetheless, progress has been uneven and not everyone has benefited from these achievements. In the mountainous region, many people lack access to quality health care because of the unequal distribution of well-trained health-care workers. Preventable deaths due to poor-quality health care for children and newborns, infants and mothers remain a concern, as do communicable diseases such as sexually transmitted infections and tuberculosis. The increasing burden of noncommunicable diseases and the health impact of worsening climate change further heighten the need for strengthened and resilient health systems, which are at risk due to an underfunded health sector and weak economy.
This CCS aims to address remaining and future challenges as well as health needs while creating an impact that is sustainable. It identifies three strategic priorities and nine deliverables (Table 1) to support the attainment of the national vision of Health for all by all, as articulated in the 9th Health Sector Development Plan 2021–2025. It contributes to the country’s goals to achieve universal health coverage, graduate from least developed country status by 2026 and attain SDGs by 2030.

To assess national-level responses to NCDs, WHO has implemented NCD country capacity surveys periodically since 2001. This report is the latest in that series. Since the first survey round, the NCD Country Capacity Survey (NCD CCS) has been conducted a further seven times, most recently in 2021. In ...the survey, completed by the NCD focal point within each country’s ministry of health or similar agency, countries are asked to report on the following topics relating to NCDs: (i) public health infrastructure, partnerships and multisectoral collaboration; (ii) policies, strategies and action plans; (iii) health information systems and surveillance; (iv) health system capacity for detection, treatment and care; and, added for 2021, (v) the impact of the COVID-19 pandemic on NCD-related resources and activities. The questionnaire is web-based and requires supporting documentation wherever possible. In the 2021 round, data were collected from May onwards, with the last survey responses arriving in September. Validation was carried out by WHO regional offices and WHO headquarters. Country responses to previous rounds of the survey were incorporated into the analysis to assess progress since 2010. Although all 194 Member States responded to the survey, data comparisons were restricted to the 160 countries that had responded to all rounds of the survey since 2010.

The Country Cooperation Strategy is the World Health Organization’s corporate framework developed in response to a country’s needs and priorities. The 2022–2025 CCS is the fourth for WHO in Sierra Leone. It is a medium-term strategic document that defines a broad framework for WHO’s work, at... all levels, with the Government of Sierra Leone and all health partners for the next four years. This document is guided by the country’s major policy and strategy documents including the 2020 National Health and Sanitation Policy (NHSP); the 2021–2025 National Health Sector Strategic Plan (NHSSP); and the 2019–2023 National Medium-term Development Plan (NMTDP). The current CCS also reflects the broad priorities of WHO as outlined in its Thirteenth General Programme of Work (2019–2023, extended to 2025) with a focus on improving access to universal health coverage, protecting people from health emergencies, and improving people’s health and well-being. The CCS priorities are also in alignment with the United Nations Sustainable Development Cooperation Framework (UNSDCF) in Sierra Leone and will contribute to attaining the country's SDG targets

During the 17 years since Surgical approaches to the urogenital manifestations of lymphatic filariasis was first published, there has been heightened awareness of the physical, economic and emotional burden of the genitourinary manifestations of filariasis. With the impetus to provide better guidanc...e for care of those suffering from LF, this update was both warranted and timely.
At the outset, the Committee noted that barriers continue to exist in care of patients affected by LF-associated morbidity. These barriers include lack of information for patients as well as for many healthcare providers, including general surgeons and others within health systems
This update offers a new consensus of the Committee regarding the staging of hydroceles caused by LF, also known as “filariceles”. It recommends integrating LF surgery with other efforts to strengthen surgical care by assessing health facilities for their surgical readiness using the WHO surgical assessment tool or “SAT”. It also recommends integratinghernia surgery with hydrocele surgery and integrating standards for prevention of surgical site infection (SSI).
The update revises recommendations for standard procedures and processes, offers an algorithm for diagnosis (including the use of ultrasound) and discusses postoperative care. It recommends collecting data using the staging and grading system described by Capuano and Capuano along with other metrics for public health management of LF.
A multifaceted approach has therefore been recommended to coordinate public health outreach with national surgical planning and local health systems to include supporting partners such as nongovernmental organizations. Surgical camps with mobile teams, as well as training of personnel at DCP3 “first level” or WHO Level II hospitals (depending on region and resources), have important roles for reducing LF morbidity.

Taenia saginata is a zoonotic tapeworm that is of economic importance in countries where cattle are kept. The parasite is transmitted from human tapeworm carriers (taeniosis) to bovines (cysticercosis) by excretion of eggs or proglottids containing eggs into the environment via the stool. Bovines ca...n then ingest the eggs through contaminated feed or water. After ingestion, the eggs hatch and release oncospheres in the small intestines, where the oncospheres penetrate the intestinal wall to reach the blood circulation. This distributes them throughout the body, but primarily to muscle tissue, where they develop into cysticerci. For humans to become infected with T. saginata, raw or undercooked bovine meat or offal containing infective cysts must be consumed. Bovine cysticercosis has been associated with various environmental factors related to water sources, such as animals having access to surface water, flooding of pastures and proximity to wastewater sources.

In 2014, an estimated 40 million women of reproductive age were infected with Schistosoma haematobium, S. japonicum and/or S. mansoni. In both 2003 and 2006, the World Health Organization (WHO) recommended that all schistosome-infected pregnant and breastfeeding women be offered treatment, with praz...iquantel, either individually or during treatment campaigns. In 2006, WHO also stated the need for randomized controlled trials to assess the safety and efficacy of such treatment. Some countries have yet to follow the recommendation on treatment and many programme managers and pregnant women in other countries remain reluctant to follow the recommended approach.

Gambiense human African trypanosomiasis is a deadly infectious disease affecting West and Central Africa, South Sudan and Uganda, and transmitted between humans by tsetse flies. The disease has caused several major epidemics, the latest one in the 1990s. Thanks to recent innovations such as rapid di...agnostic tests for population screening, a single-dose oral treatment and a highly efficient vector control strategy, interruption of transmission of the causative parasite is now within reach. If indeed gHAT has an exclusively human reservoir, this could even result in eradication of the disease. Even if there were an animal reservoir, on the basis of epidemiological data, it plays a limited role. Maintaining adequate postelimination surveillance in known historic foci, using the newly developed tools, should be sufficient to prevent any future resurgence.

Schistosomiasis is a neglected tropical disease of global medical and veterinary importance. As efforts to eliminate schistosomiasis as a public health problem and interrupt transmission gather momentum, the potential zoonotic risk posed by livestock Schistosoma species via viable hybridisation in s...ub-Saharan Africa have been largely overlooked. We aimed to investigate the prevalence, distribution, and multi-host, multiparasite transmission cycle of Haematobium group schistosomiasis in Senegal, West Africa.

The indicators and questions in this document are designed for use by national AIDS programmes and partners to assess the state of a country’s HIV and AIDS response, and to measure progress towards achieving national HIV targets. Countries are encouraged to integrate these indicators and questions... into their ongoing monitoring efforts and to report comprehensive national data through the Global AIDS Monitoring (GAM) process. In this way they will contribute to improving understanding of the global response to the HIV epidemic, including progress that has been made towards achieving the commitments and global targets set out in the new United Nations Political Declaration on HIV and AIDS: Ending Inequalities and Getting on Track to End AIDS by 2030, adopted in June 2021, and the linked Sustainable Development Goals.

A total of 18 laboratories from 13 countries participated in the four rounds of EQA: 10 laboratories from eight African endemic countries, four of which participated in all four rounds and three in three rounds. The overall results showed that the median performance of these laboratories improved ov...er the four rounds. However, the proportion of laboratories reporting false–positive cases remains high and indicates a problem of specificity probably due to contamination. The proportion of laboratories reporting both false–positive and false–negative results raises the issue of the quality of the data reported by WHO in Africa as well as the results of the studies carried out in these different laboratories in various countries.

Over the past few decades and throughout the world, the landscape of adolescent health has been altered dramatically. Currently, the total population of adolescents between the ages of 10 and 19 years is 1.2 billion – the largest generation of young people in history. The vast majority of adolesce...nts (85%) live in developing countries where, in many areas, they make up more than a third of the population. They face a variety of different experiences given the diverse political, economic, social and cultural realities within their communities. Although, for many, adolescence is a period of learning and building confidence in a nurturing environment, for others it is a period of heightened risk and complex challenges.

A Learning Programme for Professionals
4th edition
The WHO Laboratory Biosafety Manual (LBM) has been in broad use at all levels of clinical and public health laboratories, and other biomedical sectors globally, serving as a de facto global standard that presents best practices and sets trends in biosafety.
LBM encouraged countries t...o accept and implement basic concepts in biological safety and to develop national codes of practice for the safe handling of biological agents in laboratories within their geographical borders.
This fourth edition of the manual builds on the risk assessment framework introduced in the third edition. A thorough, evidence-based and transparent assessment of the risks allows safety measures to be balanced with the actual risk of working with biological agents on a case-by-case basis.
This novel evidence- and risk-based approach will allow optimised resource use and sustainable laboratory biosafety and biosecurity policies and practices that are relevant to their individual circumstances and priorities, enabling equitable access to clinical and public health laboratory tests and biomedical research opportunities without compromising safety.
