This guide provides an overview of the major elements that must be considered before, during and after the implementation of antigen-detecting rapid diagnostic tests (Ag-RDTs) for SARS-CoV-2. This guide is complementary to policy guidance issued by the World Health Organization (WHO). The guide may ...appeal to a range of audiences including Ministries of Health, donors, public and private organizations/agencies acting as implementing partners and community based and civil society organizations with experience working on health, especially organizations familiar with similar testing campaigns for other disease programmes like HIV and malaria

Essential diagnostic products areconsidered an integral part of UHC, they are an indispensable element for delivery ofservices andare also a requirement for qualitycare. Despite this realization, a review of the UHC pilot in September 2019 es...tablished that whereas the Kenya Medical Supplies Authority (KEMSA) was able to fill up to 80% of pharmaceutical items, the order fill rate for diagnostic products was less than 50 percent for level 2 and 3 facilities and as low as 30 percent for level 4 and 5 facilities.

FIND and Standard Diagnostics (SD) have developed a lateral flow rapid diagnostic test (RDT) to screen for
T.b. gambiense HAT that is cheap and easy to use. The tests are packed individually and are stable at 40°C for
up to 25 months; they are performed on fresh blood obtained from a finger prick..., and no instrument or electricity is required. The RDT detects host antibodies to infection in populations that are at risk, or in suspect individuals. Positive cases are subjected to further confirmatory methods to identify HAT patients.

Lateral-flow rapid diagnostic tests (RDTs) continue to play a vital role in global health in the management and diagnosis of infectious diseases, including malaria, HIV and COVID-19. Visually interpreted RDTs, more than any other class of diagnostics, fulfil WHO’s ASSURED criteria,1 enabling their... use at the lowest levels of health care and in self-testing.2 Their utility is, however, compromised every time a test is incorrectly performed or interpreted or its result is not available in a timely manner for clinical decisionmaking and surveillance.

Taeniasis and cysticercosis caused by the parasite T. solium affect vulnerable populations,
mainly in Latin America, sub-Saharan Africa and Asia, where pigs (the intermediate host) roam
free and poor sanitation allows pigs access to human faeces.
Clin Microbiol Infect 2010; 16: 225–231 Abstract In non-endemic countries, acute (invasive) schistosomiasis (AS) is typically seen in non-immune travellers, whereas chronic schistosomiasis is more frequently diagnosed in immigrants. Travellers with AS initially present with non-specific signs such... as fever, cough, headache, and urticaria. Life-threatening cardiac and neurological complications may occur. The positive diagnosis of AS relies on seroconversion, which appears together with hypereosinophilia approximately 3 weeks after the onset of symptoms. When prescribed during AS, praziquantel usually does not prevent the chronic phase of the disease and is associated with exacerbation of signs and symptoms in approximately 50% of cases. According to the published literature, corticosteroids may be recommended alone or in association with praziquantel. When associated with corticosteroids, pharmacokinetic interactions may impair the efficacy of praziquantel. We suggest that corticosteroids should be restricted to use in patients with systemic complications of AS, whereas praziquantel should be initiated only when ova are detected in either stools or urine, depending on the culprit species.

The article investigates the diagnostic capabilities and prevalence of chronic obstructive pulmonary disease (COPD) in primary care settings in northern Brazil. It highlights that COPD is often underdiagnosed and undertreated in resource-limited regions. The study involved 34 general practitioners a...nd used spirometry to evaluate their diagnostic accuracy compared to clinical assessments. Findings revealed significant discrepancies between GP diagnoses and spirometry results, with many false positives and negatives. The study underscores the need for better training and the use of spirometry to improve COPD diagnosis and case-finding in primary care, emphasizing the importance of targeted strategies to enhance healthcare outcomes in developing countries.

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.
