ABSTRACT
Here we report our results of a multi-center, open cohort study ("COVID-Kids-Bavaria") investigating the distribution of SARS-CoV-2 among children and staff in 99 daycare facilities and 48 elementary schools in Bavaria, Germany. Overall, 2568 children (1337 school children, 1231 preschool children) and 1288 adults (466 teachers, 822 daycare staff) consented to participate in the study and were randomly tested in three consecutive phases (September/October 2020, November/December 2020, March 2021). In total, 7062 throat swabs were analyzed for SARS-CoV-2 by RT-PCR. In phase I, only one daycare worker tested positive. In phase II, SARS-CoV-2 was detected in three daycare workers, two preschool children, and seven school children. In phase III, no sample tested positive. This corresponds to a positive test rate of 0.05% in phase I, 0.4% in phase II and 0% in phase III. After phase III, antibody testing was offered to 713 study participants in elementary schools. A seroprevalence rate of 7.7% (students) and 4.5% (teachers) was determined. We conclude that during the initial waves of the SARS-CoV-2 pandemic, the risk of a positive SARS-CoV-2 result correlated positively with the local 7-day incidence. Thus, an increased risk of SARS-CoV-2 transmission in the setting of daycare and elementary schooling was unlikely.
ABSTRACT
ObjectiveTo assess the impact of the COVID-19 pandemic on families with young children in two population-based childhood cohorts with a low and moderate COVID-19 prevalence, respectively. MethodsA cross-sectional study using online questionnaires in families from LIFE Child (n=306, Leipzig) and KUNO Kids (n=612, Regensburg) was performed at the end of the German lock-down period. Outcomes were parent-reported impact of the COVID-19 pandemic on family life, concerns and trust in political measures. ResultsMost families were concerned about the COVID-19 pandemic and lock-down measures, with major concerns directed towards the economic situation (>70%), the health of close-ones (37%), but less towards their own health (<10%). Many concerns, seeking information and approval of federal measures were more pronounced in the more affected region. Approval of lockdown measures and concerns about economic recession were related to regional differences and not significantly dependent on educational status or being personally affected by the disease. ConclusionRegional differences in approval of lockdown measures were observed and thus, measures to specifically support families according to the regional impact of the COVID-19 pandemic are needed.
