Are bars and restaurants really hot spots? Is Covid-19 really actively circulating in a private circle (family or friends)? On December 17, France finally unveiled a long-awaited large-scale study on the main locations of coronavirus infection. It was conducted by the Institut Pasteur with the assistance of the health insurance system and the contact tracing mechanism launched on 13 May.

30 330 people answered the questions of the institute in the network: 25 644 patients and 4 686 medical workers (their data were processed separately). The study was divided into two parts. The first concerns the circumstances of the infection during curfews in eight large French cities and the Ile-de-France metropolitan region. The second "compares characteristics, behaviors and practices with groupings by age, gender, region and population density during curfew and self-isolation" (October 17-29), the document notes. Consider the main points of the study.

Eating is an important part of the problem.

The authors share the infection at home (35%) and in the city (65%). "When contaminated at home (35% of cases with a known source) for adults, we are talking primarily about infection from the spouse (64% of cases)," the study says. The child is often not seen as a source of infection, as children often show little or no symptoms when they are carriers of the coronavirus.

Be that as it may, the main finding is that "food intake plays a central role in contamination, in family or friendships, and at the professional level." Study director Arnaud Fontane, an epidemiologist at the Pasteur Institute and a member of the Scientific Council, draws from all this the following conclusion: "The study shows an increase in the risk associated with visiting bars and restaurants." The inability to wear a mask while eating pushed the government (based on the advice of the Scientific Council) to delay the opening of bars and restaurants for several weeks, despite the beginning of the process of moving away from self-isolation in France.

In any case, the authors of the study urge to be vigilant. These results relate only to the curfew and self-isolation period. In addition, there may be serious inaccuracies in them, since the group selected for the study represents only a tiny fraction of all cases of infection.

It is difficult to determine the “real role” of bars and restaurants in the transmission of the virus, according to Arnaud Fontane, since the study was conducted during a period when they were partially or completely closed.

Private meetings contributed to the infection

"Of all the circumstances analyzed, most infections during the study period occurred in private meetings," the authors write. If we consider infections at "private meetings", most cases occurred "in the family circle (33.1%), in a professional environment (28.8%) and among friends (20.8%)."

Overall, the study found that “the highest risk of contracting Sars-CoV-2 is with meals and private gatherings. It will be very important to minimize this risk at meetings around Christmas and New Years."

Risk groups and risky behavior

During the study period (late October), those who did not fully comply with protective measures, as well as curfew and self-isolation rules, faced the greatest risk of contracting covid-19. Occasionally, people were thwarted by their profession, as in the case of "administrative and commercial employees, industrial workers, drivers, health workers and social workers": they "faced a higher risk of Sars-CoV-2 infection during curfews and partial self-isolation."

In other cases, people have deliberately failed to take protective measures. 44% of infected people who appear in the study "perfectly understood the risks associated with their behavior (refusal to wear a mask, maintain distance, isolate the wearer at home, etc.)."

The increased risk of infection during the study period is associated with several factors: “Living in the same home of a large number of people, including children going to school, personally participating in professional meetings, sharing a car, visiting bars, restaurants and gyms, visiting family or friends meetings ".

In addition, the study also contains surprising results: for example, public transport has not become one of the main places of infection. “Working remotely (instead of being in the office), traveling by bus or tram, playing sports on the street and visiting shops (groceries, clothing)” were found to be less risk factors for infection during curfews and partial self-isolation, according to the study.
