These guidelines provide updated evidence-based recommendations on the priority HCV-related topics from the 2018 WHO Guidelines for the care and treatment of persons diagnosed with chronic hepatitis C infection and the 2017 WHO Guidelines on hepatitis B and C testing. These priority areas are:
... direct-acting antiviral (DAA) treatment of adolescents and children ages ≥3 years of age
simplified HCV service delivery (decentralization, integration and task sharing)
HCV diagnostics – use of point-of-care (POC) HCV ribonucleic acid (RNA) assays and reflex HCV RNA testing.
These guidelines also update existing chapters without new recommendations, such as the inclusion of new manufacturers’ protocols on the use of dried blood spot (DBS) for HCV RNA testing and new data to inform the limit of detection for HCV RNA assays as a test of cure, in addition to their use for diagnosis.

Health ministries currently lack effective tools for monitoring and evaluation of schistosomiasis control programmes. Egg detection can be used, but the cost, challenges of obtaining samples, and the need for trained personnel and equipment limit the frequency of monitoring. The purpose of this TPP ...is to guide the development of new diagnostic tools to reliably measure when prevalence is above or below a cut-off of 10% in school-aged children. Communities remaining above 10% require annual MDA, while communities below 10% can reduce MDA frequency as long as < 10% prevalence can be maintained. However, the lack of a reliable test has hindered the development of maintenance strategies. The test is also needed to track changes of prevalence > 10% to ensure that annual MDA is reducing overall prevalence.

The Mediclinic article on silicosis provides an overview of this occupational lung disease caused by inhaling silica dust. It explains that inhaled silica particles lead to lung scarring and nodule formation, progressively impairing breathing. The article outlines symptoms such as shortness of breat...h, severe cough, fatigue, loss of appetite, chest pains, and fever. Diagnosis involves a medical examination, detailed occupational history, lung function tests, and imaging like chest X-rays or CT scans to detect lung scarring and nodules. While silicosis is irreversible with no specific cure, management focuses on preventing further silica exposure and treating complications. Preventive measures include maintaining high occupational health standards to control silica dust exposure.

Chagas disease is a tropical parasitic infection transmitted by crawling, blood-sucking insects (kissing bugs). You may have flu-like symptoms or none at all. But the disease can lead to life-threatening complications. With prompt treatment, most people with Chagas disease, also known as American tr...ypanosomiasis, recover fully.

Goal and objectives of the guideline
The goal of this guideline is to provide evidence-based recommendations to countries in their efforts to accomplish schistosomiasis morbidity control and elimination as a public health problem, and to move towards interruption of transmission.
The recommendatio...ns contained herein will help countries to implement national schistosomiasis control and elimination programmes and support efforts to verify the interruption of transmission.
The specific objectives are to provide guidance on:
prevalence thresholds, target age groups and frequency of preventive chemotherapy for schistosomiasis;
establishment of water, sanitation and hygiene (WASH) and snail control activities to support control and elimination of schistosomiasis;
use of diagnostic tests in humans in low transmission areas and for moving to, and evaluating the interruption of transmission of schistosomiasis;
tools for the assessment of Schistosoma spp. infection in snail hosts; and
diagnostic tests for the assessment of schistosomiasis infection in animal reservoirs of infection

This review focusses on the interactions between the etiologic agent of Chagas disease, Trypanosoma cruzi, and its triatomine vector. The flagellate mainly colonizes the intestinal tract of the insect. The effect of triatomines on trypanosomes is indicated by susceptibility and refractoriness phenom...ena that vary according to the combination of the strains. Other effects are apparent in the different regions of the gut. In the stomach, the majority of ingested blood trypomastigotes are killed while the remaining transform to round stages. In the small intestine, these develop into epimastigotes, the main replicative stage. In the rectum, the population density is the highest and is where the infectious stage develops, the metacyclic trypomastigote. In all regions of the gut, starvation and feeding of the triatomine affect T. cruzi. In the small intestine and rectum, starvation reduces the population density and more spheromastigotes develop. In the rectum, feeding after short-term starvation induces metacyclogenesis and after long-term starvation the development of specific cells, containing several nuclei, kinetoplasts and flagella. When considering the effects of T. cruzi on triatomines, the flagellate seems to be of low pathogenicity. However, during stressful periods, which are normal in natural populations, effects occur often on the behaviour, eg, in readiness to approach the host, the period of time before defecation, dispersal and aggregation. In nymphs, the duration of the different instars and the mortality rates increase, but this seems to be induced by repeated infections or blood quality by the feeding on infected hosts. Starvation resistance is often reduced by infection. Longevity and reproduction of adults is reduced, but only after infection with some strains of T. cruzi. Only components of the surface coat of blood trypomastigotes induce an immune reaction. However, this seems to act against gut bacteria and favours the development of T. cruzi.

The document titled "Fason pou Gen Laviktwa sou Kolera" (How to Achieve Victory over Cholera) provides comprehensive guidelines on the clinical presentation and management of cholera, particularly in the context of the 2010 Haiti outbreak. It emphasizes rapid rehydration as a lifesaving measure, det...ailing protocols for both oral rehydration solutions (ORS) and intravenous (IV) fluids. The document outlines appropriate antibiotic treatments based on patient categories, underscores the importance of proper sanitation, and offers strategies for effective outbreak control. Additionally, it provides guidance on recognizing severe dehydration and the necessity of immediate medical intervention to reduce mortality associated with cholera.

The CDC document "How to make oral rehydration solution (ORS)" provides clear, step-by-step instructions for preparing and using ORS to treat dehydration caused by diarrhea. It emphasizes the importance of using clean water, salt, and sugar in precise proportions to create the solution. The document... is particularly relevant in emergency settings, such as during cholera outbreaks or in areas with limited medical resources, like Haiti. It highlights the effectiveness of ORS in saving lives by rehydrating individuals suffering from severe diarrhea and encourages its use as a simple, accessible treatment method.

On 13 August 2024, Africa Centres for Disease Control and Prevention (Africa CDC) declared the ongoing Mpox outbreak a Public Health Emergency of Continental Security (PHECS). This was followed the next day by the World Health Organization (WHO), which extended the alert internationally as a public ...health emergency of international concern (PHEIC). After these declarations, many countries have made efforts to mobilize resources to introduce or expand laboratory testing, surveillance, and response activities. In particular, as the number of suspected cases surges in the Democratic Republic of Congo (DRC), Burundi, and the Central African Republic, and an increasing number of new countries report cases, there is an urgent need to implement testing to strengthen the Mpox response. However, access to appropriate quality assured diagnostics is a challenge. There is limited information on important characteristics, such as available test kits’ performance and ability to detect relevant clades.
To address the challenge of mpox access in the continent, the Africa CDC Diagnostic Advisory Committee (DAC) met in Kigali from 19-23 August 2024 to review the available evidence on molecular tests for Mpox and to shortlist tests that may be useful for Mpox testing in countries. The shortlist aims to provide guidance to Africa CDC, countries and partners on appropriate high-quality molecular tests to procure and use for the mpox response.
