Can screening and decontamination procedures performed on an outpatient basis reduce the colonization with Staphylococcus aureus and mitigate associated complications in patients undergoing elective hospital procedures? A controlled intervention study (STAUfrei).

Background: Staphylococcus aureus (SA) colonisation increases the risk of wound infections in surgical procedures. Prevention strategies to date have focused primarily on the hospital, although there are recommendations for pre-hospital decontamination at home, which can be performed by patients themselves. The current study aimed to shift the process of screening and decontamination of SA (methicillin-resistant S.

Longitudinal effects of SARS-CoV-2 breakthrough infection on imprinting of neutralizing antibody responses.

Background: The impact of the infecting SARS-CoV-2 variant of concern (VOC) and the vaccination status was determined on the magnitude, breadth, and durability of the neutralizing antibody (nAb) profile in a longitudinal multicentre cohort study.

Methods: 173 vaccinated and 56 non-vaccinated individuals were enrolled after SARS-CoV-2 Alpha, Delta, or Omicron infection and visited four times within 6 months and nAbs were measured for D614G, Alpha, Delta, BA.1, BA.

[Continuous SARS-CoV-2 monitoring in day care centres: A qualitative interview study on the experiences of childcare workers and parents with different self-sampling methods in the home environment].

Background: Since the beginning of the corona pandemic in Germany in January 2020, day care centres (DCC) have faced the challenge of reliably detecting cases of SARS-CoV-2 infection as early and reliably as possible in order to avoid major outbreaks and closures. Conducting regular virological screening tests for asymptomatic DCC children and childcare workers requires a high level of acceptance among participants and should be as easy as possible to implement. The present study aimed to evaluate childcare workers' and parents' attitudes and experiences regarding the acceptance and feasibility of various screening methods.

[Can SARS-CoV-2 Infection Status in Preschool Children be Predicted by Pandemic-related Attitudes and Concerns of their Parents? Data from the Würzburg Daycare Centre Studies (Wü-KiTa-CoV, 2020-2022)].

As part of the Würzburg KiTa-CoV study series, SARS-CoV-2 pandemic-related attitudes/concerns of parents of preschool children attending day care centres were surveyed over a 21-month period. We expected associations between these parental attitudes/concerns and their change over the course of the pandemic, on the one hand, and the SARS-CoV-2 infection status of the children, on the other. Parents of children from nine day-care centres who completed a survey on pandemic-related attitudes/concerns in October 2020, July 2021 and July 2022, were included in the analysis.
