According to Institut Pasteur ComCor study’s updated results, Covid contaminations happen in 80% of cases in closed places without ventilation, and specifically during meals.

Are gatherings in closed places, without masks, accountable for the increase in Covid contaminations? A self-evident fact for most of us, an empirical truth for Institut Pasteur that recently confirmed ComCor study’s results on the matter, released back to this December 2020.

A study that extended its sample group to come to such conclusions, including over 77,000 participants. And results are clear: “the assessment of over 10,000 unique and extra-building contacts originating infection shows this contact took place indoors, windows closed, in 80% of cases; indoors, windows open, in 15% of cases; and outdoors in 5% of cases”, searchers explain.

 Contamination mostly happens during meals… According to Institut Pasteur searchers, lunch break is accountable for 35% of contaminations in households, 42% in circles of friends, and 15% at work.

They also say that in 45% of cases, people infected know those who contaminated them. As for contaminations within households, mostly couples transmit the virus from one another. A proportion that “decreased over time (from 64% in October to 55% in January), while contaminations by children increases (from 24% in October to 33% in January)”, the study also reads.

According to the report, having a child sent to school within one’s household represents an “infection increased risk”, especially when they are taken care of by nursery assistants – in 39% of cases – when they go to junior high in 27% of cases, or to high school in 29% of cases. As for contamination outside the household, in happens within one’s family circle in 38% of cases, then in work environment in 27% of cases and last but not least in 19% of cases in friend circle.

Note the study can be put in question at any time, because of the spread of the UK, Brazilian and South African variants over the territory.
