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.

What are the goals of this site?
1. Provide guidance for health care providers, primarily physicians, about clinical diagnosis and treatment of radiation injury during radiological and nuclear emergencies. 2. Provide just-in-time, evidence-based, usable information with sufficient background and co...ntext to make complex issues understandable to those without formal radiation medicine expertise. 3. Provide web-based information that is also downloadable in advance, so that it would be available during an emergency if the internet is not accessible.

6 July 2021. Three new nucleic acid amplification test (NAAT) classes are endorsed by WHO and included.
The latest operational handbook includes the new classes recommended by WHO. It aims at facilitating the implementation of the WHO recommendations by the Member States, technical partners, and ot...hers involved in managing patients with TB and DR-TB. The operational handbook provides practical information on existing and new tests recommended by WHO, step-by-step advice on implementing and scale-up testing to achieve local and national impact and lastly, model diagnostic algorithms, which are updated to incorporate the latest recommendations. An overview of budgetary considerations and information sheets on each of the newly recommended tests is provided.

Senegal has adopted the World Health Organization–Joint United Nations Programme on HIV/AIDS recommended 90-90-90 targets.5 The adoption of this strategy means that the country is expected, by 2020, to have 90% of its population living with HIV diagnosed, 90% of all those diagnosed receiving susta...ined HIV treatment, and 90% of those receiving antiretroviral therapy having suppressed viral load measures.5 To achieve these outcomes, having good clinical laboratory services for diagnosis and follow-up will be critical.6 More specifically, investments will be needed to improve laboratory infrastructure, and to facilitate the access and availability of routine viral load and early infant diagnosis (EID) measures through the implementation of point-of-care (POC) diagnostic platforms along with an efficient and sustainable quality assurance programme.

Over 6 million people worldwide are infected with Trypanosoma cruzi, the protozoan that causes Chagas disease
(CD). T. cruzi is transmitted by triatomine insects, congenitally, through uncontrolled blood donations and organ transplants,
and via consumption of food or drink contaminated by triatomi...nes.

Following review of the latest evidence, WHO recommends that TB-LAMP can be used as a replacement for microscopy for the diagnosis of pulmonary TB in adults with signs and symptoms of TB. It can also be considered as a follow-on test to microscopy in adults with signs and symptoms of pulmonary TB, e...specially when further testing of sputum smear-negative specimens is necessary.

This document aims to present an algorithm for deciding whom to test and provide guidance on the laboratory tests for Zika virus infection diagnosis in order to support clinical diagnostic and case reporting through surveillance among EU Member States. The algorithm is not intended for clinical man...agement of patients with suspected Zika virus infection.
The information is provisional and subject to revision when new information becomes available.

In the Region of the Americas, the leishmaniases are a group of diseases caused by various species of Leishmania, which cause a set of clinical syndromes in infected humans that can involve the skin, mucosa, and visceral organs. The spectrum of clinical disease is varied and depends on the interacti...on of several factors related to the parasite, the vector, and the host. Cutaneous leishmaniasis is the form most frequently reported in the Region and nearly 90% of cases present single or multiple localized lesions. Other cutaneous clinical forms, such as disseminated and diffuse cutaneous leishmaniasis, are more difficult to treat and relapses are common. The mucosal form is serious because it can cause disfigurement and severe disability if not diagnosed and treated early on. Visceral leishmaniasis is the most severe form, as it can cause death in up to 90% of untreated people.
