[/credits]As with all highly mediatized topics, SARS-CoV-2 has its share of misinformation. Originating in the Chinese province of Hubei in 2019, the epidemic caused by this novel coronavirus, now referred to as SARS-CoV-2, and COVID-19 for the disease it causes in people, continues to stoke the fires of not just the traditional media, but also websites and social media – and not always to the good. We at Inserm suggest taking a look at the various forms that this wave of misinformation can take, so that you can focus on what is relevant.
From conspiracy theories and unfounded revelations to the plain and simple approximation of figures, when it comes to SARS-CoV-2 and its human disease COVID-19, there is no shortage of misinformation and fake news communicated through numerous media channels on subjects ranging from the nature of the virus to its vaccine.
More information on SARS-CoV-2 can be found here (in French): https://www.inserm.fr/information-en-sante/dossiers-information/coronavirus-sars-cov-et-mers-cov
The virus itself
There are many questions as to the nature of this coronavirus and its public health implications. Is it safe to receive packages coming from or via China? Does the virus affect only elderly people? Do some foods help prevent infection? Is the incubation period longer than initially thought?
Although some gray areas still surround SARS-CoV-2, we know that the virus is unable to survive on objects, such as letters and cardboard boxes, sent long distance for the time it takes for them to be reach their recipients. We also know that transmission of the virus is essentially airborne, via droplets or aerosols of saliva projected by coughing or sneezing. Therefore, an asymptomatic person (who is contaminated but is not coughing or sneezing close to others) has a lower risk of spreading the virus than a symptomatic person, except where there is close and/or prolonged physical contact. Also, the virus can be transmitted through contact with contaminated surfaces if the person touching the surface then touches their face without washing their hands first. Therefore, frequent hand washing is very important. What is more, one’s geographic or ethnic origin has no bearing on the ability of the virus to infect others.
Contrary to what might have been said in recent weeks, there are no foods (garlic, fennel) or hygiene products (sprays, mouthwashes) that prevent infection with SARS-CoV-2 . Finally, the average estimated incubation period is from 5 to 6 days, with a period of 1 to 12 days for the majority of cases. Research is continuing in order to clarify both the unanswered questions and unfounded assertions.
A vaccine for the Covid-19 epidemic?
A vaccine to prevent the contraction of SARS-CoV-2 does not exist yet. The various existing vaccines used to prevent bacterial pneumonia are unfortunately ineffective. Teams across the world, including an Inserm team in Lyon, have rallied in attempts to understand this novel virus and counter it as quickly as possible, although that will take some time. Contrary to what can be read on the more or less conspiracy theorist websites, which insinuate that a vaccine is already ready and that pharmaceutical companies are speculating on the deadliness of the epidemic in order to push up prices, the development of a vaccine is still under study – this is why the only means of protection offered to healthy populations are barrier measures.
Conspiracy theories surrounding a coronavirus patent
The conspiracy theories keep coming. Some are claiming that SARS-CoV-2 was created in the P4 laboratory in Wuhan, or that pharmaceutical companies had already filed patents to cash in on the sale of a specially-developed vaccine that will be withheld until millions have died in order to push prices up. However, the patents in question, found online, are patents for the Chinese SARS coronavirus (SARS-CoV) of 2002, which was logically then studied in order to enable the development of a vaccine. These are totally untrue.
In particular, a conspiracy theorist video pointing the finger at Inserm and Institut Pasteur is currently doing the rounds on social media. The interpretation of the documents presented in this video is totally erroneous and the allegation that Institut Pasteur had invented the virus responsible for COVID-19 is false. The 2004 patent held up as “evidence” in this video does not describe the invention of SARS-CoV-2 responsible for COVID-19, but rather the discovery of SARS-CoV-1 responsible for SARS, and the invention of a vaccine strategy following the epidemic of the latter that originated in China in 2002. This candidate vaccine against SARS-CoV-1 was not tested in humans because the epidemic ended before clinical trials could be implemented, with the lack of patients rendering them impracticable. The knowledge acquired from fighting this epidemic of a virus related to the present-day coronavirus is currently being actively used by the researchers concerned in order to create a potential vaccine against Sars-CoV-2.

Here are a few definitions of the expressions used by researchers and communicated by the media:
What is a preprint? A preprint is a paper written by researchers that has not yet undergone the standard process for publication in a scientific journal (revision, correction and peer review), which can sometimes be very lengthy. Preprints allow scientists to share research with each other in real time – in this case concerning the SARS-CoV-2 epidemic – and can be found on the Biorχiv and Medrχiv websites (which stand for Bio Archive et Med Archive, respectively).
In scientific documents such as patents, what does the term “inventor” mean?
In research, someone who discovers a virus, compound or geological deposit, for example, is designated as its “inventor”. The discovery is designated as the “invention”. In the case of the aforementioned 2004 patent, the designated “inventors” of SARS-CoV-1 that was responsible for SARS are the people who discovered and described it – they did not create it.
How are cases of COVID-19 defined?
The definition of suspected cases of COVID-19 changes with time and with the spread of the epidemic. The criteria also vary from one country to another. In France, the criteria established by its public health agency, Santé publique France, are regularly updated.
See the SARS-CoV-2 information page provided by Santé publique France (only available in French).
Do I need to get a prescription for an antimalarial to fight coronavirus?
For the moment there has been no firm scientific validation as to the efficacy of chloroquine antimalarial treatment against coronavirus. The research mentioned in the press concerns a very small study whose methodological validity is controversial.
Although the possibility of being able to use safe, well-known and inexpensive antimalarial treatments in coronavirus patients is an interesting one, it is essential to have visibility over the data produced by clinical trials involving SARS-CoV-2 patients, published and therefore made accessible to the international scientific community.
A European clinical trial evaluating four experimental treatments for COVID-19 began on March 22, 2020. Coordinated by Inserm as part of the REACTing consortium, this trial will enroll at least 800 French patients with severe forms of COVID-19: https://presse.inserm.fr/en/lancement-dun-essai-clinique-europeen-contre-le-covid-19/38737/
It must also be noted that taking any kind of medication is not without risk. Antimalarials can only be obtained on medical prescription.

Coronaviruses, which are named after the crown shape of the proteins that surround them, are a family of viruses that have a traditionally animal reservoir.
In some cases, transmission from animal to human is possible, as the SARS, MERS and probably this new virus have shown.
While these viruses are mostly benign in humans, two death-causing epidemics have been reported in recent years in the Middle East (MERS-Cov, 2012-2013) and in China ten years earlier (SARS-Cov, 2002-2003).
For this third outbreak, the outbreak would come from a fish and seafood market in Wuhan, where live animals are also sold. The search for the reservoir and host is ongoing.
Inserm is already mobilized to respond to the epidemic, under the action of the Reacting consortium, which brings together French research groups of excellence. Several initiatives have been launched:

Update on 16/09/2019
A new article published in the journal The Journal of Gerontology by Jean-Marie Robine, research director at Inserm and his Swiss and Danish colleagues, reaffirms that Jeanne Calment’s identity has not been usurped and that she died at the age 122 years old. In order to show this, they have:
– provided several mathematical models that conclude that there is a significant probability that Jeanne Calment reached the age of 122. “Thus, every 10 million centenarians, a person can reach 123 years of age.”writter the authors. A probability that is certainly small, but that is far from making Ms. Calment a statistical impossibility.
– identified the original elements that were used for the initial validation of Jeanne Calment’s identity and collected additional documentation. Cross-checking these numerous archives of various natures has shown that there was neither tax fraud nor falsification of Jeanne Calment’s identity.
In addition, Inserm collected the documents resulting from the investigation on supercentenarians conducted by Jean-Marie Robine and Michel Allard during the 1990s. These archives include written and audio documentation from Jeanne Calment, which is currently being archived and digitized at Inserm.
In the wake of the fraud allegations surrounding the age of Jeanne Calment which have received widespread mass media and social media coverage, Inserm as a leading life sciences and health research organization wishes to make clear the following:
– In 1998, following two years of research, Doctor Michel Allard from Fondation Ipsen and Jean-Marie Robine, demographer and public health researcher at Inserm published a letter in the journal Science, entitled The Oldest Human. Their findings, based on numerous civil and religious documents, supported the validity of Jeanne Calment’s death aged 122. Between them, the researchers have published several hundreds of articles in peer-reviewed scientific journals.
– The contribution of the Inserm researchers involved studying the quality of the documents available in the Arles archives (personal records, parish registries, census lists and school/military documents, etc.) and analyzing them with particular focus on the contribution of genetic factors to Jeanne Calment’s longevity. In doing so they revealed an extraordinary concentration of long-lived ancestors of Jeanne Calment and her brother François (Science 1998).
– The Fondation Ipsen study, A la recherche du secret des centenaires, for which Jean-Marie Robine had developed a specific protocol with Michel Allard, was the first to require age verification for all centenarian studies. This pioneering survey of the health and quality of life of the very elderly put an end to the use of convenience samples, ushering in the most modern epidemiological methods and questioning in the study of very old age. Since then, surveys concerning centenarians and nonagenarians endeavor to be as representative as possible. The Danish, Italian and Japanese surveys can be cited in this respect. The ongoing Five Country Oldest-Old People (5_COOP) study, also coordinated by Inserm, is based on a standardized survey conducted in the same way in Denmark, France, Japan, Sweden and Switzerland. It shows that not all centenarians are frail, suffering from dementia, or dependent and it illustrates the immense variation in health states at that age (Herr et al. 2018).
– Inserm proposes joining forces with the town of Arles in the immediate future to scan and make the genetic hypotheses and documents used to validate the lifespan of Jeanne Calment accessible to the community (Open Data).
– The researchers have 15 hours of recordings of Jeanne Calment, in the form of some thirty interviews conducted between 1992 and 1995. Before allowing public access, it must be ensured that they do not or no longer contain any information of a private or medical nature.
– Continuing the Open Science approach, an international database on supercentenarians (over 110) whose ages have been validated in 15 countries (including France) went online in 2010, marking the publication of the book Supercentenarians (www.supercentenarians.org). This database will in the near future be updated and extended to include those between the ages of 105 and 109 with the publication of a second book in the same collection. The data for the French section of this database is supplied by researchers from Inserm and INED.
– It is not within the remit of Inserm to support any requests for exhumation which do not fall within its field of competence.
– In scientific research, the burden of proof lies with those who propose new hypotheses or claim to have uncovered new findings. It is not for Inserm researchers to underpin the theory of the Russian objectors. Their arguments, should they have any, must be submitted to a peer-reviewed scientific journal which is responsible for validating the robustness of the research in question.

With the publication of the new International Classification of Diseases (ICD-11) on June 18, 2018, WHO officially recognizes the existence of a “gaming disorder”.
In its collective expert review of 2014 on addictive behaviors in adolescents, Inserm had already mentioned this form of addiction.
As part of the preparation of the French Government Plan 2013-2017 to combat drugs and addictive behaviors, the Interministerial Mission for the Fight against Drugs and Drug Addiction (Mildt) had requested that Inserm prepare an overview of scientific knowledge regarding the susceptibility of adolescents (aged 10 to 18 years) to use psychoactive substances (whose consumption is notable in young people) as well as their susceptibility to develop other habits known to potentially cause problems, particularly video games.
This research is based on scientific data available in the second half of 2013. Approximately 1,400 articles constitute the documentary basis of this expert report.
Here is what was written on the subject of video games:
In 2011, out of the 80% of 17-year-olds who stated having used the Internet in the previous seven days, approximately one in four used it for 2-5 hours a day; fewer than one in five for 5-10 hours, and one in ten used it for over 10 hours a day.
Depending on the country and the measurement method used, the prevalence of problem Internet use by adolescents is thought to vary from 2 to 12%. In France, in 2011, initial estimations show that 3-5% of 17-year-olds may be involved.
Furthermore, 5% of 17-year-olds are thought to play video games for 5 to 10 hours a day. Although the total time spent playing games is higher for boys than for girls, the time spent in front of a screen is identical, since girls are heavier users of social networking.
While video games may have positive aspects, especially regarding the development of cognitive and spatial functions, they may also lead to a loss of control and behavioral problems. Among the various types of games, MMORPG (Massive Multiplayer Online Role-Playing Games), usually played by boys, have been described as particularly addictive.
Associated harm
Apart from the time spent, which can sometimes prove to be very long, problems of a psychological and somatic nature may occur in cases of excessive use: sleep disorders, irritability, sadness, anxiety, isolation, deterioration in academic performance, problems with parents, etc. Problem use of video games may encourage use of substances (tobacco, cannabis, alcohol, energy drinks, etc.), and increase the risk of a sedentary behavior and overweight.
According to a recent report published by WHO on 05/23/2018, the death toll of the Ebola epidemic in the northwest Democratic Republic of the Congo on May 20 is 27 – out of 58 confirmed or suspected cases. The public health risk can be considered high due to its potential to spread into urban areas and neighboring countries.
The latest on Inserm’s commitment to fighting this epidemic.
Inserm and its partners at Aviesan have created REACTing, a multidisciplinary consortium bringing together research groups and laboratories of excellence in order to prepare and coordinate research to combat the health crises linked to emerging infectious diseases.
Concerning research, a significant breakthrough has been made with the identification of the so-called Ebola Zaire strain as responsible for the epidemic currently raging in the Democratic Republic of the Congo.
In April 2017, Inserm and the US National Institutes of Health and the London School of Hygiene & Tropical Medicine, in collaboration with the health authorities of Guinea and Liberia, have launched a new large-scale clinical trial of Ebola candidate vaccines, under the aegis of the international consortium PREVAC (Partnership for Research on Ebola VACcination). One year later, more than 2,000 adults and children in Guinea and Liberia have been enrolled into this international clinical trial.
Caused by a parasite of the genus Plasmodium, malaria is transmitted to humans through bites from the female Anopheles mosquito. It can also be transmitted via blood transfusion or from mother to child at the end of pregnancy. [1]
In 2016, the number of deaths caused by malaria was estimated at 445,000. Half of the world’s population is exposed to the risk of developing this disease [2], hence the need to act.
It is precisely in order to raise public awareness of the disease and increase its involvement in fighting it that World Malaria Day is held each year on April 25.
This year’s theme, “Ready to Beat Malaria”, was the ideal opportunity to highlight the work of researchers who strive all year round to combat this disease.
The work of Inserm Research Director Françoise Benoit-Vical and her team at the CNRS Coordination Chemistry laboratory focuses on understanding the mechanisms of Plasmodium resistance to artemisinin, the essential compound of antimalarial treatments, and conducting research into new antimalarial drugs. They recently demonstrated that the parasites resistant to this drug category are also resistant to many of the other antimalarials, including compounds with a hybrid chemical structure initially designed to avoid any resistance. These results raise fears of a generalized cross resistance of the parasite leading to a genuine therapeutic deadlock.
Inserm unit U1257 “Mosquito immune responses”, led by Stéphanie Blandin, seeks to understand how mosquitoes defend themselves against the parasites in order to use this anti-parasitic response to combat the transmission of malaria.
With this in mind, the laboratory is currently working on the development of two new antimalarial molecules to produce drugs that prevent transmission. This represents a critical challenge in the fight against malaria because very few existing drugs are able to eliminate the forms of the parasite transmissible to mosquitoes. As a consequence, even an individual cured of malaria may store these transmissible forms in the blood for one or two weeks – parasites which are likely to be ingested by a mosquito during a blood meal and then be passed on to someone else.

The thirteenth annual World Immunization Week will take place from April 23 to 29, 2018. The campaign, created by the World Health Organization (WHO), undertakes to raise awareness about the stakes of vaccine protection.
This year, WHO is focusing on the importance of immunizing every child to “prevent the relevant diseases and protect their lives.”
The theme of the French version of this event, coordinated by the Ministry of Health and Santé Publique France, will be infant immunization. It will be a chance to continue teaching people about immunization in the context of the extension of vaccination requirements for children under age two, which entered into force in France on January 1, 2018.
The aim of the week is to increase understanding about what immunization is while reminding people that it is the best way to prevent certain illnesses.
