In early February, after a stay in Contamines-Montjoie (Haute-Savoie), a child contracted the Covid-19. The virus was not immediately identified in the young patient who continued to attend several schools without infecting any of his classmates or teachers.
Published April 11 in the journal Clinical Infectious Diseases, the study focused on the case of this child. According to the researchers, the youngest are few vectors of the SARS-CoV-2 virus and there is another dynamic of transmission in children different from that of adults.
Coronavirus: what is the role of children in the transmission of the virus ? 9-year-old child developed mild respiratory symptoms of Covid-19 in addition to a very low viral load. As a preventive measure, two of the three schools he visited were closed for two weeks and the last one for almost a week. Infectious disease specialists conducted a survey to assess the number of people who were in contact with the patient.
In total, they identified nearly 172 individuals including 112 students and teachers assessed as at high risk of catching the coronavirus. The latter were therefore placed in quarantine. Numerous screening tests were organized among the young patient's contacts, but all of them were negative. Even the other two siblings were not infected. In contrast, they have tested positive for other viruses like the influenza A virus.
Researchers have suggested that “ children may not be important sources of transmission of the virus “. “ It is possible that children, because they do not have many symptoms and have a low viral load, transmit little this new coronavirus ” developed Kostas Danis, epidemiologist and co-author of the study at AFP.
