after reviewing and discussing the results of a multi-country study. This manual describes the resulting Practical and Precision Assessments approach and includes a discussion of the underlying concepts, factors to consider when determining what approach is appropriate, and how to interpret the collected data. The manual also includes annexes with standard operating procedures for conducting the stool and urine analyses.

- The goal of diagnostic testing for Ebola and Marburg virus diseases is to identify cases to provide timely and appropriate care and to stop disease transmission.
- All individuals meeting the case definition for Ebola or Marburg virus diseases should be tested.
- The recommended sample type
...
for testing for orthoebolaviruses and orthomarburgviruses is whole blood or plasma for living patients, and oral swab for deceased individuals.
- Laboratory confirmation of Orthoebolavirus and Orthomarburgvirus infections and further species identification should be done using nucleic acid amplification testing (NAAT).
- If a suspected case tests negative (living patient) and the blood was drawn less than 72 hours after symptom onset, a second test should be performed with blood drawn more than 72 hours after symptom onset.
- All manipulations in laboratory settings of samples originating from suspected, probable or confirmed cases of Ebola and Marburg virus diseases should be conducted with appropriate biosafety measures according to a risk-based approach.
- Whole or partial genome sequencing can be used to characterize viruses and complement epidemiologic investigations.
- Member States are strongly encouraged to share genetic sequence data (GSD) in publicly accessible databases.
- Member States are required to immediately notify the World Health Organization (WHO) under the International Health Regulations (IHR) 2005 of positive laboratory results.

, a group of conditions prevalent in tropical regions. In the “WHO Roadmap for Neglected Tropical Diseases 2021–2030”, leprosy, human African trypanosomiasis (HAT) and onchocerciasis are targeted for interruption of transmission. Acknowledging the growing necessity for establishing a process to verify the absence of new autochthonous leprosy cases, a technical guidance has been developed outlining a clear pathway, demarcating phases with
indicators and milestones leading towards the elimination of leprosy disease.

Serodiagnostic tests exist only for Tbg and are based on the detection of specific antibodies, thus they are not confirmatory of infection.

ve value of serological tests is particularly low. Field-applicable tools include the card agglutination test for trypanosomiasis (CATT) used mainly in active screening by specialized mobile teams, and the rapid diagnostic tests that are more suitable for individual testing at point-of-care. Confirmation of Tbg infection requires microscopic examination of body fluids necessitating specific training. The best performing methods are laborious and reach 85–95% diagnostic sensitivity when performed by skilled personnel.

health outcomes. The specific objectives of the guideline were to: 1. identify effective interventions to prevent early pregnancy by influencing factors such as early marriage, coerced sex, unsafe abortion, access to contraceptives and access to maternal health services by adolescents; and 2. provide an analytical framework for policy-makers and programme managers to use when selecting evidence-based interventions to prevent early pregnancy and negative health outcomes when they occur that are most appropriate for the needs of their countries and context. The recommendations and best practice statements described in this document aim to enable evidence-based decision-making with respect to preventing early pregnancy and poor reproductive outcomes among adolescents in low- and middle-income country contexts.

ing responsive and preventive behaviours through targeted communication and community engagement. Created in collaboration with the Ministry of Health, the WHO, the Global Fund and other stakeholders, the SBCC strategy implements recommendations from the 2020 external review of the National Malaria Programme. Building on previous BCC initiatives (2015–2020), it emphasises surveillance, diagnosis, treatment and vector control, particularly focusing on vulnerable populations. The SBCC strategy provides partners and implementers with a dynamic guide to designing context-specific communication interventions that support malaria elimination and prevent the re-establishment of transmission.

The document reviews past and current training activities, such as workshops on case management, entomology, vector control, epidemiology, and planning. It emphasizes the development of standardized training materials and competency frameworks, the role of national and regional training centers, and the use of blended learning methods (e.g., e-learning and in-person sessions). The goal is not just to deliver training, but to build sustainable capacity through partnerships, continuous improvement, quality assurance, and integration into health systems. It also calls for better coordination, tracking of trained personnel, and engagement of ministries of finance to ensure long-term support.

) as an additional HIV prevention choice, as part of combination HIV prevention approaches. LEN, administered twice a year as PrEP, has been shown to be highly effective at reducing the risk of HIV acquisition. In this guideline, WHO also recommends using HIV rapid diagnostic tests (RDTs) for individuals initiating or continuing long-acting injectable PrEP, such as LEN and long acting injectable cabotegravir (CAB-LA). Flexible HIV testing approaches are essential for ensuring that testing does not become a barrier to accessing or continuing PrEP, including long-acting injectable options.
