A French study once again shows minimal transmission of C19 by children.
This, to me, is another massive piece of evidence in favor of aerosols as the core route of transmission 1/ https://www.bfmtv.com/sante/peuporteurs-peu-transmetteurs-une-etude-confirme-le-role-minime-des-enfants-dans-l-epidemie-de-covid-19-1912853.html

The reason is that children infected with C19 were shown by German researchers to have similar measurable nasal viral loads to adults 2/ https://www.nytimes.com/2020/05/05/health/coronavirus-children-transmission-school.html
In the case of influenza, where such a study was made, infectious aerosols were shown to be mostly generated in the lower respiratory tract 3/
C19 certainly differs from influenza but probably through what exactly the virus does inside a cell, not through physical mechanisms that lead to aerosol generation from inflamed tissues 4/
Thus, the fact that children with C19 have significant nasal viral does doesn't imply that they often have lower respiratory tract involvement 5/
Thus, the only plausible explanation of the fact that they seem to transmit poorly is that they generate little infectious aerosol 6/
If the aerosol route is at the core of transmission, the whole social distancing-focused response to C19 is a giant clusterf*ck 7/
Most masks are also close-to-useless then, and people should have been advised to stay as much as possible outside and the focus should have been on boosting the indoor ventilation /end
