This report, published in conjunction with a summary overview of results of rounds 1–8, is the eighth and final report in a series of laboratory-based evaluations of rapid diagnostic tests (RDTs) for malaria. It provides a comparative measure of their performance in a standardized way to distingui...sh between well and poorly performing tests.
These results constitute the laboratory evaluation component of the WHO prequalification process for malaria RDTs and inform the current WHO procurement recommendations. In round 8, 35 RDTs from 17 manufacturers were assessed. For the first time the evaluation included an assessment of product performance against a panel of P. falciparum parasites with pfhrp2/3 gene deletions and therefore not expressing HRP2.

Following the publication of Guidelines on certification of elimination of human onchocerciasis in 2001 by the World Health Organization (WHO), these are the first evidence-based guidelines developed by NTD Department according to the international standards. They provide a set of recommendations th...at would guide national programme managers in collaboration with their respective oversight committees on when to stop mass drug administration (MDA) and conduct post-treatment surveillance (PTS) activities for a minimum period of 3 to 5 year before confirming the interruption of transmission of Onchocerca volvulus parasite and hence its elimination. They also include steps to undertake for verification of elimination of transmission of the parasite in the whole endemic country by the International Verification Team (IVT) prior to the official acknowledgement by WHO Director General.

The Strategy to respond to antimalarial drug resistance in Africa is a technical and advocacy document, grounded in the best available evidence to date and aimed at minimizing the threat and impact of antimalarial drug resistance of Plasmodium falciparum parasites in Africa. Its objectives are to: i...) improve the detection of resistance to ensure a timely response; ii) delay the emergence of resistance to artemisinin and artemisinin-based combination therapy (ACT) partner drugs; and iii) limit the selection and spread of resistant parasites where resistance has been confirmed.

The meeting addressed the last key area, that is, determining the best method or combination of diagnostic methods for a control programme for S. stercoralis infections in humans.
Dr Montresor’s presentation highlighted that while there is currently no “gold standard” for the... diagnosis of S. stercoralis, there is a felt urgency to optimize diagnostic regimens that are currently available, and in the context of population-based testing (as opposed to individual focused diagnostics in clinical settings).
In other words, the diagnostic test(s) should have good accuracy, but we should remember that in public health we do not aim at individual diagnosis: rather, we need a tool that should help to estimate the prevalence in a population.

This Implementation Kit (I-Kit), developed by the Health Communication Capacity Collaborative (HC3), which is funded by USAID and based at the Johns Hopkins Center for Communication Programs, offers structured guidance for improving social and behavioural change communication (SBCC) strategies relat...ed to malaria in pregnancy (MiP). Designed for programme managers and stakeholders, the toolkit addresses critical communication gaps in MiP programming, particularly among service providers. It provides tools to help users integrate MiP into situation analyses, segment audiences, define behavioural objectives and draft strategic communication plans.
MiP poses a significant public health challenge, contributing to maternal and neonatal mortality and morbidity in sub-Saharan Africa. Although effective interventions exist, such as the use of insecticide-treated nets, intermittent preventive treatment in pregnancy (IPTp) and timely diagnosis and treatment, their implementation remains inconsistent. The I-Kit supports more effective SBCC planning and implementation, with the aim of increasing the uptake and impact of these interventions and ultimately reducing malaria-related deaths and illness among pregnant women and newborns.

The "Pocket Manual for the Diagnosis and Treatment of Malaria", published by the Ministry of Health of the Sultanate of Oman, provides practical guidance for healthcare professionals on how to identify, manage, and treat malaria cases. It emphasizes parasitological confirmation before treatment, out...lines standard protocols for treating uncomplicated and severe malaria—including P. falciparum, P. vivax, and mixed infections—and specifies drug regimens based on patient weight and age. The manual also includes recommendations for travelers on malaria chemoprophylaxis and highlights the importance of prevention, especially for high-risk groups like children and pregnant women.

Epidemiology
Chagas disease (American trypanosomiasis) is caused by the protozoan parasite Trypanosoma cruzi, and transmitted to humans by infected triatomine bugs, and less commonly by transfusion, organ transplant, from mother to infant, and in rare instances, by ingestion of contaminated food or... drink.1-4 The hematophagous triatomine vectors defecate during or immediately after feeding on a person. The parasite is present in large numbers in the feces of infected bugs, and enters the human body through the bite wound, or through the intact conjunctiva or other mucous membrane.
Vector-borne transmission occurs only in the Americas, where an estimated 8 to 10 million people have Chagas disease.5 Historically, transmission occurred largely in rural areas in Latin America, where houses built of mud brick are vulnerable to colonization by the triatomine vectors.4 In such areas, Chagas disease usually is acquired in childhood. In the last several decades, successful vector control programs have substantially decreased transmission rates in much of Latin America, and large-scale migration has brought infected individuals to cities both within and outside of Latin America.

Leishmaniasis is a complex vector-borne disease involving in its transmission several species of protozoan parasites called Leishmania, a wide variety of animal reservoirs and phlebotomine sandflies vectors. Cutaneous Leishmaniasis (CL) is the most common form of the disease, and its clinical manife...stations vary from few papules to multiple ulcers affecting the skin but also the mucous membranes, leaving permanent scars and serious disability. It is a disfiguring and stigmatizing disease that often has a devastating psychosocial and economic impact on the affected resources limited communities.

About six to seven million people worldwide, mostly in Latin America, are estimated to be infected with
Trypanosoma cruzi, the parasite that causes Chagas disease (WHO data from 2021). Chagas disease is
found mainly in endemic areas of 21 Latin American countries.

Chagas disease, also known as American trypanosomiasis, is a neglected tropical disease transmitted by triatomine insects, first identified in 1909. Chagas disease affects approximately 6–7 million peop...le globally and is highly prevalent in Latin America where most cases are reported. However, there is increasing evidence that Chagas disease is now an important public health issue outside the “classical” endemic countries due to population migration. Our understanding of Chagas disease, including its pathologies and factors relating to progression, remains to date limited, and is also challenged by lack of diagnosis and highly effective treatment. This systematic review aims to describe studies with Chagas patients receiving antiparasitic treatment. Databases were searched for relevant studies published after 1997, and the results of these searches were screened.

Localized cutaneous leishmaniasis and its evolving forms (diffuse cutaneous leishmaniasis, mucosal leishmaniasis and cutaneous leishmaniasis recidivans), together with the sequela of visceral leishmaniasis (post-kala-azar dermal leishmaniasis), account for about one million cases of dermal leishmani...ases per year worldwide. Although not lethal, the dermal leishmaniases cause chronic, disfiguring skin lesions which are an important cause of morbidity and stigma.
