Of the test subjects, 5204 pupils or teachers from a primary school (49.7 percent) and 5260 students or teachers from a middle and lower secondary school (50.3 percent). 308 of the samples obtained were unusable (2.9 percent), mainly because the respective school physicians did not correctly transfer the gargle water to a container. 40 of the remaining 10,156 samples were positive. This corresponds to an overall prevalence (positive result rate) of 0.39 percent with a fluctuation range of 0.28 to 0.55 percent.
