children are weakly contagious, study finds

The study of the contamination site at Covid-19, in Haute-Savoie, at Contamines-Montjoie, reveals that the 9-year-old child, carrying the SARS-Cov-2 virus, did not transmit the disease despite very close interactions with his family circle and in his school. This suggests, according to the researchers, a different dynamics of transmission in children.

The 9 year old child who contracted the Covid-19 in Les Contamines-Montjoie in Haute-Savoie did not transmit the virus to no one in the three schools he attended, according to a study that concludes that children would be few vectors of the disease. It was one of the first homes (cluster) in France. At the end of January, a Briton returning from Singapore joined compatriots in the ski resort, including a family resident of the resort.

This case " suggests that children may not be a significant source of transmission of this new virus (and suggests) different transmission dynamics in children ", Concludes the study. While they are an important vector for other viruses such as influenza for example.
