Initial report of decreased SARS-CoV-2 viral load after inoculation with the BNT162b2 vaccine / Nature Medicine, mars 2021. The recently authorized BNT162b2 Coronavirus Disease 2019 (COVID-19) messenger RNA (mRNA) vaccine is approximately 95% efficient in preventing polymerase chain reaction (PCR)-confirmed symptomatic disease from 7 d after the second dose and also provides some early protection starting 12 d after the first dose1,2.
Un bond de géant pour la modélisation des protéines du virus du Covid-19 / Recherchecovid.enseignementsup-recherche.gouv.fr, mars 2021. Afin de développer des traitements efficaces contre le Covid-19, des simulations ont été développées pour étudier la structure 3D de différentes protéines du virus SARS-CoV-2, ainsi que leur évolution sur de courtes échelles de temps.
Un modèle réaliste de cette cible protéique permettrait de repérer des points faibles sur lesquels se focaliser, afin de trouver quelles molécules pharmaceutiques sont capables de les attaquer. Bien menée, cette approche est beaucoup plus rapide et efficace que s’il fallait passer au crible tous les composés disponibles : seules les molécules repérées comme prometteuses par la simulation sont alors testées. La protéase principale du virus est une cible très importante car cette protéine, impliquée dans la réplication du virus, mute peu.
Covid-19 : ces variants qui ont changé la donne / CNRS, mars 2021. Alors que les campagnes de vaccination promettaient d’accélérer la fin de l’épidémie, l’apparition de différents variants du virus du Covid-19 l'ont, au contraire, fait repartir de plus belle.
Malgré ce timing délétère, l’émergence de mutations reste un phénomène naturel qui a d’autant plus d’occasions de survenir que l’épidémie se propage. Mais qu’est-ce qui distingue les variants apparus en Angleterre, en Afrique du Sud et au Brésil des toutes premières souches ? « La terminologie est souvent utilisée de façon brouillonne, au risque de laisser passer des informations erronées », souligne Bruno Lina, professeur des universités, chercheur au Centre international de recherche en infectiologie1 et praticien hospitalier aux Hospices civils de Lyon, qui est également directeur du Centre national de référence des virus infectieux respiratoires et membre du conseil scientifique. « Le Covid-19 est provoqué par un virus unique : le SARS-CoV-2.

Key Points Question What are the clinical outcomes after hospitalization for COVID-19?
Findings Four months after hospitalization, in an uncontrolled cohort study of 478 survivors of COVID-19, at least 1 new-onset symptom was reported by telephone interview by 244 patients (51%), including fatigue in 134 of 431 (31%), cognitive symptoms in 86 of 416 (21%), and dyspnea in 78 of 478 (16%). Computed tomographic lung scan abnormalities were reported in 63% of 171 patients assessed at an ambulatory visit, mainly subtle ground-glass opacities. Fibrotic lesions were observed in 19% of these 171 patients.
Meaning This study provides clinical status of a cohort of patients 4 months after hospitalization for COVID-19, but further research is needed to understand longer-term outcomes.

Introduction Methods We conducted a matched cohort study. Inclusion criteria. Reopening schools in the context of increasing COVID-19 community transmission: The French experience / Science direct, février 2021. 1.
Introduction Children have a very unique position in the COVID-19 pandemic. Infected children rarely develop severe forms of the disease [1], [2], [3], and there is considerable epidemiological evidence in favor of reduced susceptibility to infection [4], [5] and reduced ability to transmit the infection [6], [7], [8], [9]. These data have called into question the usefulness of the school closures that accompanied the first lockdown measures in most countries in the spring of 2020. This questioning was all the more necessary since these school closures were accompanied by numerous deleterious effects on the physical and mental health of children and by increased social inequalities [10], [11], [12], [13].

First real-world UK data shows Pfizer-BioNTech vaccine provides high levels of protection from the first dose / Public Health England, february 2021.
Data analysed by Public Health England (PHE) shows the Pfizer-BioNTech vaccine provides high levels of protection against infection and symptomatic disease from the first dose. Early data from PHE’s SIREN study shows a promising impact on infection in healthcare workers aged under 65. Healthcare workers in the study are tested for coronavirus (COVID-19) every 2 weeks – whether or not they have symptoms. Data shows one dose reduces the risk of catching infection by more than 70%, rising to 85% after the second dose. This suggests the vaccine may also help to interrupt virus transmission, as you cannot spread the virus if you do not have infection. PHE’s analysis of routine testing data also shows that one dose is 57% effective against symptomatic COVID-19 disease in those aged over 80.
Early data suggests the second dose in over 80s improves protection against symptomatic disease by a further 30%, to more than 85%.

Abstract : The 1st phase of 2020 confinement seems to have lead French consumers to reflect on their way of life and their daily practices. Through the lens of the immersion process, this research aims to study the impact of the lock-down on sustainable food practices. Three sets of data were collected over the period, allowing to analyze the profiles of change in food habits. Results show that confinement has led to more sustainable food consumption for 30% of the respondents, mainly due to an increase of local and seasonal product purchases.

Résumé. Emergence of a Novel SARS-CoV-2 Variant in Southern California, JAMA Network, février 2021. A spike in coronavirus disease 2019 (COVID-19) has occurred in Southern California since October 2020. Analysis of the severe acute respiratory syndrome coronavirus (SARS-CoV-2) in Southern California prior to October indicated most isolates originated from clade 20C that likely emerged from New York via Europe early in the pandemic.1 Since then, novel variants of SARS-CoV-2 including those seen in the UK (20I/501Y.V1/B.1.1.7), South Africa (20H/501Y.V2/B.1.351), and Brazil (P.1/20J/501Y.V3/B.1.1.248) have emerged with the concern of increased infectivity and virulence.2,3 Thus, we analyzed variants of SARS-CoV-2 in Southern California to establish whether one of these known strains or a novel variant had emerged. Regulatory review with waiver of consent was completed by Cedars-Sinai Medical Center (CSMC).
Of 2311 samples at CSMC, 192 were selected and 185 (67 inpatient; 118 outpatient) underwent phylogenetic analysis, along with 1480 representative genomes using Nextstrain. Immune evasion means we need a new COVID-19 social contract / The Lancet, février 2021. Les recherches INRAE à l'heure de la pandémie de Covid-19 / La recherche mobilisée Covid 19, février 2021.
La pandémie de Covid-19 a mis en lumière notre manque de connaissances sur les risques d’émergence de nouvelles épidémies, leur prévention et leur contrôle. Sur ces points, l’approche interdisciplinaire de type « Une seule santé » (One Health – Eco Health) [...] prend tout son sens. Alors que tous les continents sont touchés par la pandémie de Covid-19, la recherche scientifique mondiale s’est mobilisée dès l’apparition de l’épidémie en Chine pour aider les sociétés à faire face à cette crise. De par la pluridisciplinarité de ses recherches, INRAE participe activement à de nombreux projets de recherche. Les chercheurs INRAE de disciplines variées, de la virologie à la sociologie en passant par l’épidémiologie, l’écologie ou les mathématiques, ont unis leurs compétences pour produire des connaissances et aider les décideurs dans la gestion de la pandémie de Covid-19. Evidence of early circulation of SARS-CoV-2 in France: findings from the population-based “CONSTANCES” cohort / European Journal of Epidemiology , 2021.
Participants were aged 55 (min: 19, max: 79) years at sample collection; 4623 (51%) were female; 1503 (16%) were living in Ile de France, 935 (10%) in Grand-Est—these two regions being the French regions with the highest incidences of hospitalization for COVID-19 during the first semester 2020, 6706 (73%) were living in the other 10 mainland regions. Three-hundred and fifty-three (3.9%) participants were ELISA-S positive, 138 were undetermined and 8653 were negative (undetermined and negative, 96.1%).
The proportion of ELISA-S positive increased from 1.9% (42 of 2218) in November and 1.3% (20 of 1534) in December to 5.0% (114 of 2268) in January, 5.2% (114 of 2179) in February and 6.7% (63 or 945) in the first half of March (P < 0.001, Trend test; Fig. 1). Neutralizing antibodies were detected in 44 (0.48%) participants (23 with a titer of 40, 12 with a titer of 80, 9 with a titer of 160), were undetermined in 15 participants, negative in 498 and not done in 8597 (Fig. 2). Factors associated with the spatial heterogeneity of the first wave of COVID-19 in France: a nationwide geo-epidemiological study / The Lancet, février 2021.
Introduction The spread of the COVID-19 pandemic has exhibited important heterogeneity between countries and regions.1 Spatial differences between incidence and mortality rates have been associated with factors as various as the arrival time of SARS-CoV-2,2 population age structure,3 urban development and population density,4 economic level,4 health system,5 climatic and meteorological factors,6 and anti-contagion policies and practices.7, 8, 9 In France, the first COVID-19 case was confirmed on Jan 24, 2020. An exponential epidemic then spread rapidly, resulting in a national lockdown from March 17, 2020. The first wave peaked on March 31, and lockdown ended on May 11 (panel). Seroprevalence and risk factors of exposure to COVID-19 in homeless people in Paris, France: a cross-sectional study / The lancet, février 2021. Introduction A nationwide lockdown was implemented in France between March 17 and May 11, 2020, to contain the spread of COVID-19.
Important differences in seroprevalence were observed between regions: from only 1–3% in the least affected area (Nouvelle Aquitaine) to 9–11% in Ile-de-France, the region that includes Paris.1, 2, 3 Differences in professions and living conditions also created uneven COVID-19 exposure risk,4, 5, 6, 7, 8, 9 with those experiencing homelessness particularly exposed to the disease. During the nationwide lockdown in France, French authorities (assisted by non-governmental entities) relocated people living in the streets or camps into emergency shelters, usually reassigned hotels, to reduce widespread transmission. Some people were hosted temporarily in large venues such as gymnasiums before reaching these shelters. Research in context Evidence before this study.
Maximizing Fit for Cloth and Medical Procedure Masks to Improve Performance and Reduce SARS-CoV-2 Transmission and Exposure, 2021 / CDC, février 2021. Summary What is already known about this topic? Universal masking is recommended to slow the spread of COVID-19. Cloth masks and medical procedure masks substantially reduce exposure from infected wearers (source control) and reduce exposure of uninfected wearers (wearer exposure). What is added by this report? CDC conducted experiments to assess two ways of improving the fit of medical procedure masks: fitting a cloth mask over a medical procedure mask, and knotting the ear loops of a medical procedure mask and then tucking in and flattening the extra material close to the face.

Background The psychological impact of the COronaVIrus Disease 2019 (COVID-19) outbreak and related lockdown measures among the Italian population are unknown. The COVID-19 pandemic is a global health emergency that could potentially have a serious impact on public health, including mental health (1, 2). Since clusters of atypical pneumonia of unknown aetiology were discovered in the city of Wuhan, Hubei province, in late December 2019, the viral disease has continued to exponentially spread throughout China and worldwide.
Italy has been the first European country that had to face the pandemic. On March 9th 2020, lockdown measures were enforced by the government on entire national territory. As previously reported, health emergencies such as epidemics can lead to detrimental and long-lasting psychosocial consequences, due to disease related fear and anxiety, large-scale social isolation, and the overabundance of (mis)information on social media and elsewhere (3).
