Timely detection of novel coronavirus (2019-nCoV) infection cases is crucial to interrupt the spread of this virus. We assessed the required expertise and capacity for molecular detection of 2019-nCoV in specialised laboratories in 30 European Union/European Economic Area (EU/EEA) countries. Thirty-...eight laboratories in 24 EU/EEA countries had diagnostic tests available by 29 January 2020. A coverage of all EU/EEA countries was expected by mid-February. Availability of primers/probes, positive controls and personnel were main implementation barriers.

Sequencing SARS-CoV-2 in the Americas
The COVID-19 Genomic Surveillance Regional Network was created in 2020 not only to strengthen the sequencing capacity in the participating laboratories, but also for them to establish a routine SARS-CoV-2 genomic sequencing, as a strategy to increase the amoun...t of genetic sequence data available to the global community, which is critical to support the development of diagnostic protocols, the information for vaccine development and to better understand the evolution and molecular epidemiology of the SARS-CoV-2.

This report describes the geographical and temporal distribution of multidrug-resistant (MDR) tuberculosis (TB) using molecular typing data reported by European Union (EU)/European Economic Area (EEA) Member States for 2015 and the preceding years.
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.

This algorithm is addressed to laboratories
with established capacity(molecular, antigenic and/orserological) to detect dengue (DENV), Zika (ZIKV), and chikungunya(CHIKV) as part of the differential diagnosis for arborviruses. A BSL2 containment level is required to handle suspected samples.
Interim Guidance 31 march 2020
WHO has established a shipment mechanism to expedite and cover the costs of the shipment of clinical samples from patients with suspected COVID-19 from the country of collection to one of the WHO reference laboratories providing confirmatory molecular testing for COVI...D-19. This document explains the process and documentation required for shipment of specimens.

The meeting addressed the last key area, that is, determining the best method or combination of diagnostic methods for a control programme for S. stercoralis infections in humans.
Dr Montresor’s presentation highlighted that while there is currently no “gold standard” for the... diagnosis of S. stercoralis, there is a felt urgency to optimize diagnostic regimens that are currently available, and in the context of population-based testing (as opposed to individual focused diagnostics in clinical settings).
In other words, the diagnostic test(s) should have good accuracy, but we should remember that in public health we do not aim at individual diagnosis: rather, we need a tool that should help to estimate the prevalence in a population.

Dada a atual situação da pandemia da COVID-19, os países são orientados a continuar a adotar os algoritmos diagnósticos para tuberculose (TB) recomendados pela OPAS/OMS. Apesar das diferenças nos modos de transmissão da TB e do vírus responsável pela COVID-19, certas medidas de proteção p...essoal são relevantes para ambas as doenças. As medidas de rotina para a proteção contra a TB devem continuar, juntamente com precauções adicionais para proteger os trabalhadores contra a COVID-19.
