“…Il s'agit d'un Betacoronavirus probablement transmis à l'homme par le pangolin, sur le marché de fruits de mer de Huanan, situé dans la ville de Wuhan [10]. La transmission interhumaine a entrainé la propagation du virus vers la Thaïlande puis vers d'autres pays, causant une pandémie aujourd'hui [11].…”

J o u r n a l P r e -p r o o f 1 RésuméLa propagation du nouveau coronavirus SARS-CoV-2, découvert en Chine en janvier 2020, a mené à une pandémie dès mars 2020, obligeant chaque système de soins des pays touchés à une adaptation rapide. Pour mieux faire face à cette crise sanitaire majeure, qui a donné lieu à de nombreuses publications scientifiques, nous avons synthétisé les principales études cliniques originales afin de faciliter la prise en charge au quotidien des patients atteints de COVID-19.Nous détaillons les premiers signes et l'évolution de la maladie ainsi que les différentes formes cliniques, y compris extra-pulmonaires, telles qu'elles sont connues au début de cette pandémie.Nous insistons sur les marqueurs cliniques, biologiques et scannographiques prédictifs de sévérité ou de mortalité. Enfin, nous discutons de l'impact de l'infection par le SARS-CoV-2 dans les populations suspectes d'être à haut risque de formes sévères. AbstractThe spread of the new coronavirus SARS-CoV-2, discovered in China in January 2020, led to a pandemic as early as March 2020, forcing every health care system in the affected countries to adapt quickly. In order to better address this major health crisis, which has given rise to numerous scientific publications, we have synthesized the main original clinical studies to facilitate the day-to-day management of patients with COVID-19.We detail the early signs and progression of the disease as well as the different clinical forms, including extra-pulmonary, as known at the beginning of this pandemic. We focus on clinical, biological and CT markers predictive of severity or mortality. Finally, we discuss the impact of SARS-CoV-2 infection in populations suspected to be at high risk of severe forms.

“…To assess the sensitivity of assays using the Corman RdRp and E-gene primer/probe sets, we ran them on dilutions of the positive UW Virology clinical sample. The LOD was found to be 1:2x10 4 for both (again 20 replicate assays for each primer/probe set were performed and all 20 were positive). We also tested the specificities of assays using these sets by running them on our collection of samples positive for various respiratory viruses.…”

More than 100,000 people worldwide are known to have been infected with SARS-CoV-2 beginning in December 2019. The virus has now spread to over 93 countries including the United States, with the largest cluster of US cases to date in the Seattle metropolitan area in Washington. Given the rapid increase in the number of local cases, the availability of accurate, high-throughput SARS-CoV-2 testing is vital to efforts to manage the current public health crisis. In the course of optimizing SARS-CoV-2 testing performed by the University of Washington Clinical Virology Lab (UW Virology Lab), we tested assays using seven different primer/probe sets and one assay kit. We found that the most sensitive assays were those the used the E-gene primer/probe set described by Corman et al. (Eurosurveillance 25(3), 2020, https://doi.org/10.2807/1560-7917.ES.2020.25.3.2000045) and the N2 set described by the CDC (Division of Viral Diseases, Centers for Disease Control and Prevention, 2020, https://www.cdc.gov/coronavirus/2019-ncov/downloads/rt-pcr-panel-primer-probes.pdf). All assays tested were found to be highly specific for SARS-CoV-2, with no cross-reactivity with other respiratory viruses observed in our analyses regardless of the primer/probe set or kit used. These results will provide invaluable information to other clinical laboratories who are actively developing SARS-CoV-2 testing protocols at a time when increased testing capacity is urgently needed worldwide.

Background: At the height of the COVID-19 pandemic, Thailand had almost depleted its critical care resources, particularly ICU beds and ventilators. This prompted the necessity to develop a national guideline for resource allocation. This paper describes the development process of a national guideline for critical resource allocation in Thailand during the COVID-19 pandemic. Methods: The guideline development process consisted of three steps (1) rapid review of existing rationing guidelines and literature; (2) interviews of Thai clinicians experienced in caring for COVID-19 cases; and (3) multi-stakeholder consultations. At steps 1 and 2, data was synthesized and categorized using a thematic and content analysis approach and this guided the formulation of the draft guideline. Within Step 3, the draft Thai critical care allocation guideline was debated and finalized before entering the policy-decision stage. Results: Three-order prioritization criteria consisting of (1) clinical prognosis using four tools (Charlson Comorbidity Index, Sequential Organ Failure Assessment, Frailty Assessment, and Cognitive Impairment Assessment); (2) number of life years saved; and (3) social usefulness, were proposed by the research team based on literature reviews and interviews. At consultations, stakeholders rejected using life years as a criterion due to potential age and gender discrimination, as well as social utility due to a concern it would foster public distrust as this judgment can be arbitrary. It was agreed that attending physician is required to be the decision maker in the Thai medico-legal context while a patient review committee would play an advisory role. Allocation decisions are to be documented for transparency and no appealing mechanism is to be applied.This guideline will be triggered only when demand exceeds supply after the utmost efforts to mobilize surge capacity. Once implemented, it is applicable to all patients, COVID-19 and non-COVID-19, requiring critical care resources prior to ICU admission and during ICU stay.Conclusions: The guideline development process for the allocation of critical care resources in the context of the COVID-19 outbreak in Thailand was informed by scientific evidence, medico-legal context, existing norms and societal values to reduce risk of public distrust given the sensitive nature of the issue and ethical dilemmas of the guiding principle though it was conducted at recorded speed. Our lessons can provide an insight for the development of similar prioritization guidelines, especially in other LMICs.
