Leptospirosis is a perplexing conundrum for many. In the existing literature, the pathophysiological mechanisms pertaining to leptospirosis is still not understood in full. Considered as a neglected tropical zoonotic disease, leptospirosis is culminating as a serious problem worldwide, seemingly exi...sting as co-infections with various other unrelated diseases, including dengue and malaria. Misdiagnosis is also common as non-specific symptoms are documented extensively in the literature. This can easily lead to death, as the severe form of leptospirosis (Weil’s disease) manifests as a complex of systemic complications, especially renal failure. The virulence of Leptospira sp. is usually attributed to the outer membrane proteins, including LipL32. With an armament of virulence factors at their disposal, their ability to easily adhere, invade and replicate within cells calls for a swift refinement in research progress to establish their exact pathophysiological framework. As an effort to reconstitute the current knowledge on leptospirosis, the basis of leptospiral infection, including its risk factors, classification, morphology, transmission, pathogenesis, co-infections and clinical manifestations are highlighted in this review. The various diagnostic techniques are also outlined with emphasis on their respective pros and cons.

To meet the need for laboratory diagnosis to be integrated in community care, the new 2022 Update describes point-of-care tests that can be performed both in district laboratories and peripheral healthcare facilities by non-specialist staff. Also included are recently developed self-tests.
ASLM in collaboration with the Africa Centres for Disease Control and Prevention, and in partnership with the Clinton Health Access Initiative, Amref and Last Mile Health present the Quality Assurance Framework for SARS-CoV-2 Antigen Rapid Testing for Diagnosis of COVID-19. This framework aims to pr...ovide general technical guidance to African Union Members States on the rollout, establishment, implementation, monitoring, and evaluation of SARS-CoV-2 Ag RDT interventions so as to effectively and efficiently detect, control and minimise errors in the performance of COVID-19 laboratory testing processes. It describes the core components for quality assurance, resources mobilisation and advocacy for scale up, monitoring, evaluation, learning and accountability for SARS-CoV-2 implementation.

The purpose of this document is to provide guidance on the use of pooled sample testing strategy in coronavirus disease (COVID-19)
testing laboratories of the African Union Member States for scaling up SARS-CoV-2 nucleic acid testing capacity with the available resources. The current document descr...ibes the effect of factors such as the prevalence of COVID-19 in the population to be tested, the homogeneity of pools, and the sensitivity of the molecular test in optimal pool size determination. It also highlights the importance of monitoring the prevalence of COVID-19 in a population to be tested and proper validation of the test, to limit the potential for false-negative results. Validation studies to determine the optimal pool size by testing laboratories are recommended as the optimum approach. A safe, simple ‘two-stage pooling’ option has been indicated in this guidance to be used by laboratories until such validation can be achieved.
