Research on aerosol dispersion in secondary schools


From 17 August, the first secondary schools and schools for special secondary education will be fully reopened. Pupils do not have to keep a distance of five feet from each other, but they do have to keep them from teachers.

According to Patricia Bruijning, pediatrician epidemiologist at UMC Utrecht, it is not yet clear to what extent secondary schools can cause the corona virus to spread. Because although the virus is mainly transmitted through coughing and sneezing, there are serious indications, according to UMC Utrecht, that this also happens via aerosols.


These tiny moisture droplets, which spread through shouting, talking, singing, and even breathing, linger in the air much longer than the larger cough or sneeze drops and can spread beyond five feet. In combination with poor ventilation and many students in one place, this can be a source of the spread of the corona virus.

Together with TU Delft, Erasmus MC and IRAS, UMC Utrecht will conduct research into how aerosols behave in the air under different ventilation conditions. A random sample of twenty secondary school students is also used to examine the ventilation, classroom interior, windows and the number of students in their school. In addition, air samples are taken to monitor the presence of the virus in the school.
