France: 32 cases of Breton #coronavirus variant B.1.616 reported

On April 14, 32 cases of infection with the 20C / 655Y (B.1.616) variant were confirmed (29 in Brittany, three in other regions). All cases have a direct or indirect link with the enhanced surveillance zone by Brittany. The majority of the cases relies on the transmissions within the hospital clusters in the zone.

A few cases have been reported in connection with a chain of transmission in the community but, to date, there are significant dissemination of this variant in the population has not been documented, whether in Brittany or elsewhere. Epidemiological investigations are continuing to characterize the episode and monitor the spread of this variant.

France: 25 cases of Breton Variant #coronavirus B.1.616 recorded so far, 22 in Brittany, 3 elsewhere

Clade 20C variant that emerged in Brittany.  A cluster of infections with a 20C clade variant (“20C / 655Y variant” or B.1.616), was detected in the Côtes d´Armor, with cases occurring between January and March 2021. The particularity associated with the cases confirmed infections with this variant is the possibility of presenting symptoms suggestive of COVID-19 with negative RT-PCR on usual nasopharyngeal swabs.

The virus is nevertheless detectable by the usual PCR techniques but seems to be found in a preferential in the lower airways. To date, it has not been shown that this variant would be more transmissible or lead to more severe forms. Reinforced surveillance has been put in place in the geographical area concerned in Brittany. A national case investigation protocol suggestive of infection with the 20C / 655Y variant has been disseminated to identify and describe the cases that may occur outside this geographic area. In case of suspicion of infection with this variant (investigation protocol available on the website of Public Health France), samples beyond the nasal sphere pharyngeal gland should be offered whenever possible to increase the sensitivity of the diagnosis by RT-PCR.

As of April 07, 25 cases of infection with the 20C / 655Y variant have been confirmed by the CNR (22 in Brittany, 3 in other regions). All cases have a direct or indirect link with the enhanced surveillance zone by Brittany. The majority of cases are linked to transmissions within hospital clusters in the area. A few cases have been reported in connection with a chain of transmission in the community but, to date, there are significant dissemination of this variant in the population has not been documented, either in Brittany or elsewhere. Epidemiological investigations are continuing to characterize the episode and monitor the spread of this variant.

Breton #Coronavirus Variant: 26 confirmed cases, 12 deaths

This Thursday, a 26th case of the Breton variant was confirmed at the Guingamp hospital center. The spread of this new form of covid-19 seems to be limited to Trégor. To date, 12 patients have died from it. Frail, elderly and / or people with co-morbidities.

However, it is impossible to conclude that there is a higher mortality caused by this variant compared to the others. The problem lies in the difficulty of detecting this mutant which often nestles deep in the respiratory system, rendering conventional nasopharyngeal PCR tests negative. “We have a surveillance bias. We have the results where we are able to find the virus. That is to say in the hospital, in people intubated in intensive care, for whom we can perform effective deep samples,” explains Alain Le Tertre, head of the Brittany unit of Public Health France.

France: Breton #coronavirus variant of interest 20C/H655Y now under national surveillance

The French Directorate General for Health (DGS) has reported to healthcare establishments and professionals the new course of action to be taken to monitor the 20C / H655Y variant of Covid-19 detected for the first time in Brittany between January and March 2021.

On Tuesday, the DGS sent a new protocol to ensure enhanced surveillance of cases of Sars-CoV-2 infection linked to the 20C / H655Y variant, several cases of which were identified in mid-March at the Lannion hospital center (Côtes-d’Armor). The last assessment given on Friday reported 13 confirmed cases (including one spotted in Ile-de-France) with 7 deaths.

The peculiarity of the confirmed cases is that the patients had symptoms suggestive of Covid-19 but an RT-PCR “weakly positive or even negative on the usual nasopharyngeal swabs”, recalls the DGS.

Currently, cases have been confirmed outside of Brittany but all remain linked to Lannion. However, “in the absence of data concerning a possible increased transmissibility of this virus and / or a greater frequency of severe forms, this variant is at this stage classified as a variant to follow (VOI, variant of interest )”, indicates the DGS.

France: full #coronavirus lockdown with school closures demanded by scientists and medics

194 new deaths and nearly 43,000 new cases reported today, Contamination and the number of patients in intensive care remain at high levels, confirming the arrival of a third epidemic wave announced by Olivier Véran.

Researchers plead for a month of strict containment. The prospect of a strict and generalized reconfinement resurfaces due to the hospital tension. Researchers and doctors plead for long-term measures.

Mircea Sofonea, lecturer in epidemiology at the University of Montpellier (Hérault), is on the same line. “According to my models, it would be necessary to confine strictly, as in March 2020, at least for six weeks, judges this specialist. This deadline would make it possible to find an incidence rate below 5,000 new cases per actual day, the threshold set by Emmanuel Macron in November to accept deconfinement. We would also arrive at less than 2000 patients in intensive care and a less active circulation of the virus. It all depends on the health objectives set, in particular at the level of hospital occupation. Currently, Covid-19 patients are being cared for at the expense of deprogrammed patients. We will then have to catch up. ”

France #coronavirus “Breton Variant” French Health Department statement

Variant de clade 20C ayant émergé en Bretagne

Un cluster d’infections par un variant de clade 20C (« variant 20C/H655Y »), a été détecté dans un hôpital des Côtes d’Armor, avec des cas survenus entre janvier et mars 2021. La particularité associée aux premiers cas confirmés d’infections à ce variant est la possibilité de présenter des symptômes évocateurs de la COVID-19 avec une RT-PCR faiblement positive, voire négative, sur les prélèvements naso-pharyngés habituels.

Le virus est néanmoins détectable par les techniques de PCR habituelles mais semble être retrouvé de manière préférentielle dans les voies aériennes basses. À ce jour, il n’est pas démontré que ce variant serait plus transmissible ni qu’il entraînerait de formes plus sévères, mais son émergence fait l’objet d’investigations et la situation est suivie sur le territoire via une surveillance spécifique. En cas de suspicion d’infection à ce variant (définition de cas et conduite à tenir, disponibles sur le site internet de Santé publique France), des prélèvements au-delà de la sphère naso-pharyngée chaque fois que possible doivent être proposés pour augmenter la sensibilité du diagnostic par RT-PCR. Selon les informations disponibles à ce jour, tous les cas confirmés du variant 20C/H655Y ont un lien épidémiologique direct ou indirect avec une commune des Côtes d’Armor et la diffusion du variant 20C/H655Y semble donc limitée actuellement à ce secteur géographique.

A cluster of infections by a 20C clade variant (“20C / H655Y variant”) was detected in a hospital in Côtes d’Armor, with cases occurring between January and March 2021. The particularity associated with the first confirmed cases of Infections with this variant is the possibility of presenting symptoms suggestive of COVID-19 with weakly positive or even negative RT-PCR on usual nasopharyngeal swabs. The virus is nevertheless detectable by the usual PCR techniques but seems to be found preferentially in the lower airways. To date, it has not been shown that this variant would be more transmissible or that it would lead to more severe forms, but its emergence is being investigated and the situation is being monitored in the territory via specific surveillance. In case of suspicion of infection with this variant (case definition and action to be taken, available on the website of Public Health France), samples beyond the nasopharyngeal sphere whenever possible should be proposed to increase the sensitivity of the diagnosis by RT-PCR. According to the information available to date, all the confirmed cases of the 20C / H655Y variant have a direct or indirect epidemiological link with a municipality in Côtes d’Armor and the spread of the 20C / H655Y variant therefore seems to be currently limited to this geographical area.

Breton variant: 13 cases of the new #coronavirus strain confirmed

Public Health France has indicated that the Breton variant is limited to “a town in Côtes-d’Armor and the distribution of the 20C/H655Y variant therefore seems to be currently limited to this geographical area”. The geographical area is the city of Lannion.

Among the 13 confirmed cases, 11 come from the epidemic focus at the Lannion hospital center , another in the population (which is currently in strict confinement) and another in the Paris region, detected within the Pitié-Salpêtrière hospital.

Of these 13 confirmed cases, the ARS also confirms 7 deaths, including 5 contaminations with the Breton variant were detected by post-mortem samples. The remaining 6 are hospitalized. “Nothing indicates for the moment that this variant would be more contagious and more severe”, wishes to underline the ARS.

Ninth case of Breton Variant of #covonavirus found in France

“Professor Arnaud Fontanet, member of the scientific council, indicated Tuesday morning on on BFMTV that a ninth case of this Breton variant had been confirmed. According to our information, it could be a contamination spotted at the Pitié-Salpêtrière hospital in Paris, linked to the Lannion hospital center.”

Which territories are under surveillance?

In Brittany, five agglomerations are placed under surveillance (Morlaix, Lannion, Guingamp-Paimpol, Leff Armor and Saint-Brieuc). “In these areas, more extensive samples can be taken, in addition to the classic PCR, to try to identify this variant”, informs Stéphane Mulliez, director general of the Brittany regional health agency.

France #coronavirus Breton variant: “It worries us as it is more difficult to detect by nasopharyngeal swab and can therefore go unnoticed.”

Will the measures announced be enough to curb the epidemic in France? We are already close to 100% saturation in intensive care. Whatever happens, we have two to three weeks before us before the measures taken have an effect on the intensive care admissions, during which the English variant will complete occupying the space.

Should we be afraid of the Breton mutant?  It worries us as it is more difficult to detect by nasopharyngeal swab and can therefore go unnoticed. This makes the detection and isolation of patients difficult. Investigations are in progress by sequencing and by serology to estimate the extent of its diffusion. But it is too early to determine the magnitude and severity associated with it.

New Breton variant of #coronavirus that evades PCR tests “a specific variant of the 20C clade”

A new variant (derived from Clade 20C) has been detected in the context of a cluster at the Lannion hospital center, in the Côtes d’Armor. …several patients presenting typical symptoms suggesting an infection by SARS-CoV-2 but a negative RT-PCR test result on nasopharyngeal samples and for whom the diagnosis could be made by serology or by performing RT-PCR on deep respiratory samples.

Where was the “Breton variant” discovered?

The alert was given after the Breton SARS-CoV-2 mutation was detected in a cluster that formed at the Lannion hospital center , in Côtes-d’Armor, in early March.  Of the 79 cases of contamination, eight people were carriers of this variant. These eight people died. For now, there is nothing to link their death to the variant.

French Health Department Press Release – 15th March 2021  “Following the identification by sequencing, in Brittany, of a new variant (derived from Clade 20C), the health authorities put in place the necessary monitoring and support measures.”

 

French Health Department Annex 1 – 15th March 2021 “Definition of SARS-CoV-2 (COVID-19) infection and action to be taken concerning a new variant detected in Brittany (variant of clade 20C) “

Due to the recent emergence of a new variant initially detected at the Lannion Hospital Center (a variant
specific to the 20C clade, different from other 20C viruses currently circulating in France 1 ), a case definition specific is proposed for this variant.

French Health Department Annex 2 – 15th March 2021 Population diagnostic strategy concerning a new variant of clade 20C detected in Brittany

Identify the cases of infection in the population by the new variant of clade 20C in the persons residing or having stayed at a consistent time period with the period of contamination, in an area defined in the document “Definition of cases of infection SARS-CoV-2 (COVID-19) and what to do about a new variant
detected in Brittany (variant of clade 20C) ”

French Health Department Annex 3 – 15th March 2021 Diagnostic strategy for active case finding in hospitals concerning a new variant of clade 20C detected in Brittany”

Goals:

1- Identify cases in hospitals in connection with the cluster of new variant of the 20C clade detected in Brittany and to objectify the impact of circulation of the 20C clade variant in these establishments.

2- Identify the cases of infection by the new variant of clade 20C among the patients hospitalized on national territory who fall within the definition of case as defined in the document “Definition of cases of infection with SARS- CoV-2 (COVID-19) and what to do about a new variant detected in Brittany (variant of clade 20C) ”.

3- Explore the sites and the kinetics of viral excretion for the 20C variant

New French #coronavirus variant may be invisible to PCR tests

French authorities are investigating a new coronavirus variant, derived from clade 20C, found in the western Brittany region that is more difficult for tests to detect, though for now it does not appear to be more dangerous or contagious.

Stephane Mulliez, director of the regional ARS health service, said at a press conference Tuesday that a hospital biologist in Lannion, a city on the English Channel, sounded the alert after studying dozens of recent deaths.

Seven of the victims had shown classic coronavirus symptoms despite having negative PCR tests, which analyse nasal swabs and are usually highly accurate.

Further testing, of blood as well as mucus samples from deeper in the respiratory tract, confirmed the COVID diagnosis in the patients, who were all elderly and had underlying health risks, Mulliez said.
