Seroprevalence of SARS-CoV-2 in German secondary schools from October 2020 to July 2021: a longitudinal study.

Purpose: To quantify the number of SARS-CoV-2 infections in students and teachers in 14 Secondary schools in eastern Saxony, Germany. Seroprevalence of SARS-CoV-2 antibodies in study population. Number of undetected cases.

Kinetics and seroprevalence of SARS-CoV-2 antibodies: a comparison of 3 different assays.

Comparing seroprevalence and antibody kinetics in three different commercially available assays for SARS-CoV-2. Serostatus of COVID-19 patients was analyzed 5 months and 10 months after their infection, using three different assays: Diasorin LIAISON, Euroimmun, Abbott Diagnostics ARCHITECT. Seropositivity at baseline differed significantly depending on the assay (Diasorin 81%, Euroimmun 83%, Abbott 59%).

SARS-CoV-2 seroprevalence in students and teachers: a longitudinal study from May to October 2020 in German secondary schools.

Objective: To quantify the number of SARS-CoV-2 infections in secondary schools after their reopening in May 2020.

Design: Repeated SARS-CoV-2 seroprevalence study after the reopening of schools and 4 months later.

Setting: Secondary school in Dresden, Germany.

Different Neural Processing of Umami and Salty Taste Determined by Umami Identification Ability Independent of Repeated Umami Exposure.

There is a large inter-individual variation for umami taste perception. However the neural mechanism for this variability is not well understood. This study investigated brain responses to umami and salty taste among individuals with different umami identification abilities and the effect of repeated oral umami exposure on umami identification and neural processing of taste perceptions.
