4th edition
The WHO Laboratory Biosafety Manual (LBM) has been in broad use at all levels of clinical and public health laboratories, and other biomedical sectors globally, serving as a de facto global standard that presents best practices and sets trends in biosafety.
LBM encouraged countries t...o accept and implement basic concepts in biological safety and to develop national codes of practice for the safe handling of biological agents in laboratories within their geographical borders.
This fourth edition of the manual builds on the risk assessment framework introduced in the third edition. A thorough, evidence-based and transparent assessment of the risks allows safety measures to be balanced with the actual risk of working with biological agents on a case-by-case basis.
This novel evidence- and risk-based approach will allow optimised resource use and sustainable laboratory biosafety and biosecurity policies and practices that are relevant to their individual circumstances and priorities, enabling equitable access to clinical and public health laboratory tests and biomedical research opportunities without compromising safety.

The Global guidance framework for the responsible use of the life sciences: mitigating biorisks and governing dual-use research (the framework) aims to provide values and principles, tools and mechanisms to support Member States and key stakeholders to mitigate and prevent biorisks and govern dual-u...se research.
The framework adopts the One health approach and focuses on the role that responsible life sciences research can play in preventing and mitigating risks caused by accidents, inadvertent or deliberate misuse with the intention to cause harm to humans, nonhuman animals, plants and agriculture, and the environment.

he Framework sets the requirements for facilities handling High Consequence Agents and Toxins (HCATs) and guides the implementation of laboratory biosafety and biosecurity practices associated with the design, commissioning, routine operation safe and secure biocontainment laboratories.
Second edition. June 2022. This revised guidance recommends that access to COVID-19 testing is decentralized as far as possible and made available at health facilities, and through the use of self tests to enable access to care and the mitigation of transmission. Testing should be prioritized for hi...gh-risk and vulnerable individuals presenting with acute onset of respiratory illness so that those found to be infected can benefit from clinical care and access to COVID-19 therapeutics and vaccines

Tuberculosis (TB) is the deadliest infectious disease in most low- and middle-income countries, claiming more than 4,000 lives each day. The unprecedented COVID-19 pandemic has seriously impacted people with pre-existing health conditions. People with TB are usually more vulnerable to other infectio...ns, including the novel coronavirus, due to pre-existing lung damage. They are also at higher risk of developing complications from COVID-19.

9 March 2022, Timely and accurate diagnostic testing for SARS-CoV-2 is an essential part of a comprehensive COVID-19 response strategy. Ag-RDTs can be performed by individuals in which they collect their own specimen, perform a simple rapid test and interpret their test result themselves at a time a...nd place of their choosing, termed COVID-19 self-testing. This interim guidance provides a new recommendation that COVID-19 self-testing, using SARS-CoV-2 Ag-RDTs, should be offered as part of SARS-CoV-2 testing services. It also includes implementation considerations that can guide decisions on whether, and how, to adopt self-testing in different contexts, including the populations being prioritized; the disease prevalence in that population; and the impact on accessibility of testing, health care services and result reporting.

This guidance addresses rationale, risk-based scenarios, practical considerations prior to adoption of the self-testing products, quality assurance, safety and ethical considerations, and data management considerations for COVID-19 self-testing. The Africa CDC recommends the use of rapid antigen sel...f-testing within two key scenarios. The first includes testing for case identification within scenarios with a high risk of infection, including symptomatic cases and contacts of a confirmed case. The second scenario involves general screening within scenarios of low or unknown risk exposure allowing for self-care such as before gatherings with at-risk individuals and prior to participation in events involving members of different households. Within these scenarios, a positive test result indicates likelihood of current infection, while a negative test result indicates a lower risk of active infection, though it does not rule out infection altogether. All positive cases should be managed following the national COVID-19 management protocol of Member States.ssur

A OMS revisou o Regulamento Sanitário Internacional em 2005 “para ajudar a comunidade internacional a prevenir e a responder aos riscos agudos de saúde pública que tenham o potencial de cruzar fronteiras e ameaçar pessoas em todo o mundo”. Esses regulamentos exigem que todos os 196 estados-membros da OMS estejam bem preparados para surtos em potencial e novas doenças; isso inclui o diagnóstico precoce e a confirmação laboratorial para facilitar a prevenção e o controle de infecções.

Interim guidance, 6 October 2021
Direct detection of SARS-CoV-2 viral proteins (antigens) in nasal swabs and other respiratory secretions using lateral flow immunoassays (also known as rapid diagnostic tests, RDTs) offers a faster and less expensive method to test for SARS-CoV-2 than the reference ...method, nucleic acid amplification tests (NAATs). This interim guidance offers recommendations on the priority uses of antigen-detecting rapid diagnostic tests (Ag-RDTs) in specific populations and settings, including (i) for primary case detection in symptomatic individuals suspected to be infected and asymptomatic individuals at high risk of COVID-19, (ii) for contact tracing, (iii) during outbreak investigations and (iv) to monitor trends of disease incidence in communities. Ag-RDTs meeting minimum performance requirements can be used outside of clinical and laboratory settings, including in communities, by trained operators in accordance with instructions. The guidance additionally provides recommendations on implementation, product selection and storage.

La détection directe des protéines virales du SRAS-CoV-2 (antigènes) dans les écouvillons nasaux et autres sécrétions respiratoires à l'aide de tests immunologiques à flux latéral (également appelés tests de diagnostic rapide, TDR) offre une méthode plus rapide et moins coûteuse pour te...ster le SRAS-CoV-2 que la méthode de référence, les tests d'amplification des acides nucléiques (TAAN). Ces lignes directrices provisoires offrent des recommandations sur les utilisations prioritaires des tests de diagnostic rapide à détection d'antigène (TDR-Ag) dans des populations et des contextes spécifiques, notamment (i) pour la détection primaire des cas chez les personnes symptomatiques suspectées d'être infectées et les personnes asymptomatiques à haut risque de COVID-19, (ii) pour la recherche des contacts, (iii) pendant les enquêtes sur les épidémies et (iv) pour surveiller les tendances de l'incidence de la maladie dans les communautés. Les TDR-AG répondant aux exigences minimales de performance peuvent être utilisés en dehors des milieux cliniques et des laboratoires, y compris dans les communautés, par des opérateurs formés conformément aux instructions. Le guide fournit en outre des recommandations sur la mise en œuvre, la sélection des produits et le stockage
