Weekly Epidemiological Record. This report summarizes application of the SAFE strategy against trachoma during 2023. It includes estimates of the global population at risk of trachoma blindness based on district-by-district data submitted to WHO by national programmes. Summarizing the epidemiologica...l situation in this way is inherently complex because, for any district, up to 3 serial estimates of prevalence may be valid at different times during a calendar year.

Due to the heterogeneous distribution of malaria transmission and its determinants, subnational tailoring (SNT) provides an analytical framework to facilitate the targeting of each population with appropriate intervention packages for maximum impact to inform national strategic planning and prioriti...zation based on resources available. The WHO Global Malaria Programme recommends the use of subnational data on disease epidemiology and other relevant local contextual factors to facilitate the process of SNT. Once the strategies and intervention mixes have been defined, programmes can proceed to the prioritization of
interventions for effective programming, based on available resources

Technical Update
Areas of Africa endemic for Buruli ulcer (BU), caused by Mycobacterium ulcerans, also have a high prevalence of human immunodeficiency virus (HIV), with adult prevalence rates between 1% and 5% (Maps). However, there is limited information on the prevalence of BU–HIV coinfection.... Preliminary
evidence suggests that HIV infection may increase the risk of BU disease (1–3). In the Médecins Sans Frontières project in Akonolinga, Cameroon, HIV prevalence was approximately 3–6 times higher among BU patients than the regional estimated HIV prevalence (2). Similarly in Benin and Ghana, BU
patients were 8 times and 3 times respectively more likely to have HIV infection than those without BU (1, 3). Further study is needed to clarify this association and enhance knowledge about the prevalence ofBU–HIV coinfection in endemic areas.

Pandemics and outbreaks have differential impacts on women and men. From risk of exposure and biological susceptibility to infection to the social and economic implications, individuals’ experiences are likely to vary according to their biological and gender characteristics and... their interaction with other social determinants. Because of this, global and national strategic plans for COVID-19 preparedness and response must be grounded in strong gender analysis and must ensure meaningful participation of affected groups, including women and girls, in decision-making and implementation.

Nested case-control study of health workers exposed to confirmed COVID-19 patients.
Similar objectives to the cohort study but case-control studies may be cheaper and provide robust evidence to characterize and assess the risk factors for SARS-CoV-2 infection in health workers exposed to COVID-19 p...atients.
Health workers with confirmed COVID-19 will be recruited as cases and other health workers in the same health care setting without infection will be recruited as controls (incidence density sampling).
Secondary objectives are similar to the cohort study.

In the context of the coronavirus disease (COVID-19) pandemic response, WHO identifies young people as a priority target audience with specific concerns, experiences and behaviours. This policy brief provides relevant insights from behavioural evidence and a set of behavioural considerations for tho...se promoting COVID-19 preventive behaviours among young people. Designers of programmes and initiatives targeting youth may find it helpful to refer to the youth-specific barriers and drivers identified in this policy brief and to prioritize these for testing when planning initiatives targeted at young people.

Several countries have demonstrated that COVID-19 transmission from one person to another can be slowed or stopped. This document has been prepared based on the evidence currently available about Coronavirus disease 2019 (COVID-19) transmission (human-to-human transmission primarily via respiratory... droplets from, or direct contact with, an infected person), and is designed to ensure that the accommodation sector can protect the health of its staff and clients.

Prepared by the Independent Panel for Pandemic Preparedness and Response for the WHO Executive Board, January 2021
“The world was not as prepared as it should have been, and it must do better,” concludes a WHO panel reviewing the pandemic response "
The document “Malaria Elimination Programme Review, India 2022”, published by the WHO Country Office for India, provides an in-depth assessment of India’s progress toward malaria elimination. It evaluates the structure, implementation, and effectiveness of national and subnational malaria prog...rams, focusing on surveillance, diagnosis, treatment, vector control, and community engagement. The review identifies strengths, challenges, and areas for improvement, offering evidence-based recommendations to accelerate India's efforts to eliminate malaria by 2030.

The Council was established in late 2020 by Dr Tedros Adhanom
Ghebreyesus (Director-General, WHO) to provide new economic thinking – reassessing how health and wellbeing are valued, produced and distributed across the economy. An all-female group of 10 distinguished economists and area experts, t...he Council has focused on reimagining how to put Health for All at the heart of government decision-making and private sector collaboration at regional, national and international levels.

Relapsing malaria caused by Plasmodium vivax parasites poses a significant challenge to global malaria elimination efforts. About one third of the population remains at risk of contracting P. vivax malaria, and 85% of P. vivax infections stem from reactivated latent parasites, leading to chronic ana...emia and increased morbidity and mortality. In addition to diagnostic tools that can detect the acute, blood-stage of P. vivax, new tools are needed to detect the dormant infections before they reactivate and contribute to morbidity and onwards transmission

WHO recommends artemisinin-based combination therapies for treating uncomplicated malaria, alongside studies to monitor treatment effectiveness. Given the threat of antimalarial resistance, including partial resistance in several African countries, molecular tools are vital for tracking resistance. ...In 2015, WHO launched the External Quality Assessment scheme for nucleic acid amplification testing to ensure reliable lab results. Coordinated by WHO and operated by the United Kingdom National External Quality Assessment Service for Parasitology, the scheme provides quality-controlled specimens and reports to help improve testing accuracy. Experts recently discussed expanding the scheme to include antimalarial resistance markers.

Meeting report, Kampala, Uganda,
7–8 November 2023
Vector control, alongside case management, remains the most effective approach to controlling and eliminating malaria. Key interventions, such as indoor residual spraying (IRS) and long-lasting insecticidal nets (LLINs), have significantly reduced malaria transmission in many African countries. This... has enabled some countries to transition from the control phase to the elimination phase.

This toolkit is a comprehensive set of practical tools and resources designed to support country-level risk communication and community engagement (RCCE) practitioners, decision-makers, and partners to plan and implement readiness and response activities for yellow fever outbreaks. The toolkit conta...ins: information about yellow fever; RCCE considerations for how to approach key issues during yellow fever outbreaks; tools for understanding the context in which yellow fever outbreaks occur; methods for collecting data to inform strategy development and bring evidence into planning and implementation of activities; guidance to support vector control and immunization campaigns; and links to existing RCCE tools and training. It is one of a suite of toolkits on RCCE readiness and response to a range of disease and response areas.
