Dresden (dpa / sn) - Another study on the frequency of corona infections does not see schools as hotspots in the pandemic.
In the second test phase between May and October there were no undetected infections in the schools examined, the medical faculty of the TU Dresden and the Dresden University Hospital announced on Monday.
The study was commissioned by the government of Saxony.
After the schools reopened in May and before the autumn break, doctors examined more than 2000 blood samples from schoolchildren aged 15 and from teachers at 13 secondary schools in Dresden and Eastern Saxony.
In spring, antibodies were detected in twelve samples as an indication of a survived corona infection - according to the information, the number remained constant until autumn.
Although about half of the students and 16 percent of the teachers said they had a respiratory infection between the two tests, it said.
In seven of the twelve cases, the corona infection was not known.
The data showed that the detection of Sars-CoV-2 antibodies in the adolescents was very low, at least until the autumn vacation, according to study leader Professor Reinhard Berner.
"This is all the more remarkable since the number of infections in Saxony has doubled during this period."
Neither during the first wave nor in the four months after reopening were there any indications that the schools had developed into “silent hotspots”.
Depending on the infection rate, a third examination at the schools is planned for the end of 2020 or beginning of 2021.

In parallel, the Leipzig University had already examined the frequency of corona infections in Saxon schools in the summer and came to a similar result.
The government saw itself confirmed in its course to enable regular operation under pandemic conditions.
