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.

This document provides up-to-date guidance on laboratory studies as well as smallscale (semi-field) and large-scale field trials to assess the efficacy and determine field
application rates of new molluscicide products for control of schistosomiasis.
Interium guidance, 25 June 2021Timely and accurate diagnostic testing is an essential tool in preventing and controlling the spread of COVID-19. This document describes recommendations for national testing strategies and the use of PCR and rapid antigen tests in different transmission scenarios of t...he COVID-19 outbreak, including how testing might be rationalized in low resource settings. All testing should be followed by a strong public health response including isolating those who test positive and providing them care, contact tracing and quarantine of contacts.

Mem Inst Oswaldo Cruz . 2021 Jan 29;115:e200287. doi: 10.1590/0074-02760200287. eCollection 2021. Sensitivity and negative predictive value were directly affected by sample storage conditions. RT-PCR and virus isolation showed greater dependence on well-conserved samples for an accurate diagnosis
orientations provisoires, 25 juin 2021. Des tests de diagnostic rapides et précis sont un outil essentiel pour prévenir et contrôler la propagation du COVID-19. Ce document décrit les recommandations relatives aux stratégies nationales de dépistage et à l'utilisation de la PCR et des tests an...tigéniques rapides dans différents scénarios de transmission de l'épidémie de COVID-19, y compris la manière dont les tests pourraient être rationalisés dans les milieux à faibles ressources. Tous les tests doivent être suivis d'une réponse de santé publique forte, comprenant l'isolement des personnes dont le test est positif et la fourniture de soins, la recherche des contacts et la mise en quarantaine des contacts.
