It was the first center of the coronavirus epidemic in France. The town of Crépy-en-Valois, in Hauts-de-France, was the first to count a French death following Covid-19, a 60-year-old teacher. Europe 1 exclusively reveals to you this Thursday the results of an epidemiological study carried out with 661 people by the Institut Pasteur within the school and in the entourage of high school students, which indicates in particular that the risk of family contamination is quite low.

Little risk of family contamination
If the conclusions of this study reveal that 41% of high school students and teachers of the establishment were infected with the virus, they also show that only 17% of the parents of the high school students concerned, and 21% of their brothers and sisters, were infected not the Covid-19. By living under the same roof, the risk of contamination is therefore quite low. "Even in the family circle, at a time when we did not know that the coronavirus was circulating and therefore without special precautions, we pass from 10 to 20% of infected people", underlines at the microphone of Europe 1 Arnaud Fontanet, epidemiologist at the Pasteur Institute and member of the scientific council which carried out this study.

> How to keep sleep during confinement?
Only 10% of people infected in a cluster
If the delta of 10% of infected people between the families of affected high school students and the others may seem good news, it is actually a bad omen for collective immunity. "The propensity of people infected at the end of the first wave is not that high. We are in any case very far from the 66% necessary to have population immunity," said the specialist.
This study also confirms that women are affected as much as men by the virus, which corroborates an assessment of Public Health France published last week, and also that the elderly are more likely to develop a serious form. But the Institut Pasteur above all proves that the loss of taste and smell is indeed a symptom of Covid-19, in 9 out of 10 cases.
