Evidence-based guidelines are one of the most useful tools for improving public health and clinical practice. Their purpose is to formulate interventions based on strong evidence of efficacy, avoid unnecessary risks, use resources efficiently, reduce clinical variability and, in essence, improve hea...lth and ensure quality care, which is the purpose of health systems and services. These guidelines were developed following the GRADE methodology, with the support of a panel of clinical experts from different countries, all convened by the Pan American Health Organization. By responding to twelve key questions about the clinical diagnosis and treatment of dengue, chikungunya, and Zika, evidence-based recommendations were formulated for pediatric, youth, adult, older adult, and pregnant patients who are exposed to these diseases or have a suspected or confirmed diagnosis of infection. The purpose of the guidelines is to prevent progression to severe forms of these diseases and the fatal events they may cause. The recommendations are intended for health professionals, including general, resident, and specialist physicians, nursing professionals, and medical and nursing students, who participate in caring for patients with suspected dengue, chikungunya, or Zika. They are also intended for health unit managers and the executive teams of national arboviral disease prevention and control programs, who are responsible for facilitating the process of implementing these guidelines.

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.

Three classess of tests are now recommended in the latest consolidated guideles on tests for tuberculosis infection. It includes for the first-time a new class of Mycobacterium tuberculosis antigen-based skin tests (TBSTs), and the two existing classes of tests: the tuberculin skin test (TST) and t...he interferon-gamma release assays (IGRAs).
IGRAs and TBSTs use Mycobacterium tuberculosis complex specific antigens and represent a significant advancement to TST which has been used for over half a century.

This report’s central premise is that diagnostics and therapeutics, and associated test to treat strategies, are fundamental components of the pandemic response, both for COVID-19 and for future health threats. Two years into the COVID-19 pandemic, this report reflects on the main challenges and k...ey solutions on the road to equitable access to diagnostics and therapeutics.
This report draws from experience gained through the Access to COVID-19 Tools (ACT) Accelerator Diagnostics and Therapeutics pillars, and includes the perspectives of collaborating stakeholders (countries, civil society representatives and the private sector). Building on these findings, this report proposes sixteen recommended actions to address what have been identified as key structural challenges and specifies a potential owner for each action.

These guidelines provide new and updated recommendations on the use of point-of-care testing in children under 18 months of age and point-of-care tests to monitor treatment in people living with HIV; the treatment monitoring algorithm; and timing of antiretroviral therapy (ART) among people living w...ith HIV who are being treated for tuberculosis.
New recommendations launched today outline key new actions that countries can take to improve the delivery of HIV testing, treatment and care services by providing greater options for differentiated approaches such as, supporting HIV treatment start in the community, ensuring that children are diagnosed and treated early, and that viral load treatment monitoring is more accessible, focused and triggers clinical action

Dengue is a significant public health problem. There are four dengue virus serotypes identified; however, its diagnosis is difficult due to the existence of many viruses, bacteria, and parasites producing the same clinical presentation, being present in the same geographical area and even producing ...coinfections. Therefore, determining whether a person has, had, or is infected with dengue virus is of great importance. In order to do so, direct and indirect laboratory tests have been developed to identify the virus or part of its structure that generally detects the antibody response. These techniques are used for diagnosis, epidemiological studies, monitoring, assessment and production of vaccines and antivirals, etc. They range from the use of cell cultures, animal models, inoculation by insects, and serology tests to the use of detection molecular tests and quantification of genetic material that are described in this chapter herein, a brief explanation of this methodology, its strengths and weaknesses, and its application in the dengue research.

The updated List of Essential Diagnostics contains 46 general tests that can be used for routine patient care as well as for the detection and diagnosis of a wide array of disease conditions, and 69 tests intended for the detection, diagnosis and monitoring of specific diseases.
The List is divid...ed into two sections depending on the user and setting: one for community settings, which includes self-testing; and a second one for clinical laboratories, which can be general and specialized facilities.

PLoS Negl Trop Dis 13(10): e0007694. In 2005, the World Health Organization (WHO) recognized Chagas disease (CD; Trypanosoma cruzi infection) as a neglected tropical disease (NTD) [1] and included it into the global plan to combat NTDs [2]. The Target 3.3 of the United Nations Sustainable Developmen...t Goals (UN/SDG) aims at ending the epidemics of NTDs by 2030 [3]. Mother-to-child (congenital/connatal) transmission is currently the main mode of transmission of T. cruzi over blood transfusions and organ transplantations in vector-free areas within and outside Latin America (LA). Based on recent demonstrations that congenital transmission can be prevented [4–7], WHO has shifted its objective, in 2018, from control to elimination of congenital CD (cCD).

The meeting was held from 26 to 27 March 2018 to review and discuss the following topics:
Advances and challenges in the use of fTLC, and new approaches to detecting mycolactone using monoclonal antibodies (mAbs).
The status of development of rapid diagnostic tests (RDTs) targeting the MUL..._3720 protein.
The role of PCR as a reference test, and hurdles in providing a confirmatory diagnosis and in establishing a quality assurance programme.
New molecular tools with potential for implementation at a level lower than in the national or regional reference laboratory, such as loop-mediated isothermal amplification (LAMP) and recombinase polymerase amplification (RPA).
The need to harmonize and standardize methods for collection and preparation of specimens, so samples can be referred for diagnosis and stored for evaluation of new diagnostic tests in optimal conditions.
Barriers to accessing early diagnosis and treatment, including coordination at the programme level, and lack of adequate diagnostic tools.
Defining target product profiles (TPPs) to guide the development of new diagnostic tools that can be applied at different levels of the health system. Participants agreed that two TPPs would be developed to address the current gaps: (i) a rapid test for BU diagnosis at the primary health-care level; and (ii) a test for diagnosis of BU that can also assist in treatment monitoring and differential diagnosis at the district hospital or reference centre.
