Adults and children are equally exposed to infection with COVID-19, but children are almost four times more chances to transfer coronavirus asymptomatic. At the same time, adults often transmit a virus to other peers, while children are infected from other children. Researchers from the University Hospital of Liege in Belgium came to such conclusions, Daily Mail writes about it.
It is reported that in the framework of the study, a program of testing and tracking in a local elementary school was created. The study was conducted from September to December 2020, 63 children took part in it and 118 adults.
In the observation period, approximately equal to the share of adults and children has become infected with COVID-19. Of the 63 children who participated in the study were infected with 13. Among 118 adults were identified 32 cases of infection. At the same time, only four adults did not observe the symptoms of coronavirus. Of the 13 infected children, the symptoms did not have six.
It is noted that children had 3.8 times more chances to transfer the virus as meaningful than their teachers and other school staff. The average time for the appearance of symptoms in children was zero, and in adults amounted to 15 days.
Previously, scientists from the United States put forward a new version of the appearance of the coronavirus SARS-COV-2. In their opinion, the virus could evolve from the infection found from the Chinese miner, which has become infected in 2012. The executive director of the American organization Bioscience Resource Project Jonathan Latem explained that viruses can pass many evolutionary stages in the body of one person.
In October, it was reported on the article by scientists published in Journal of the American Medical Association, which said about the international team of researchers, showed that the transfusion of blood plasma undergoing coronavirus infection does not help in the treatment of critical patients with COVID-19.
