Background: In winter 2022/2023, a resurgence of invasive group A streptococcal (iGAS) infections in children was observed in Europe, including Germany and Switzerland. While a simultaneous increase in consultations for scarlet fever and pharyngitis was reported in England, leading to the recommendation to treat any suspected GAS disease with antibiotics, guidelines in Germany and Switzerland remained unchanged. We aimed to investigate whether this policy was appropriate., Methods: We conducted a retrospective multicenter study of children hospitalized for invasive GAS disease between September 2022 and March 2023 in pediatric departments in Dresden and Berlin (Germany) and Basel (Switzerland). We reviewed medical records and conducted structured telephone interviews to analyze whether suspected GAS infections with or without antibiotic treatment were reported prehospitalization., Results: In total, 63 patients met the inclusion criteria (median age 4.2 years, 57% males); however, clinical information was not complete for all analyzed characteristics; 32/54 (59%) had ≥1 physician visit ≤4 weeks prehospitalization. In 4/32 (13%) patients, GAS disease, that is, tonsillitis or scarlet fever, was suspected; 2/4 of them received antibiotics, and a positive rapid antigen test for GAS was documented in 1 of them., Conclusions: A small minority of patients had suspected GAS infection within 4 weeks before iGAS disease. These data suggest that there is little opportunity to prevent iGAS disease by antibiotic therapy, because in most patients-even if seen by a physician-there was either no evidence of GAS disease or when GAS disease was suspected and treated with antibiotics, consecutive invasive GAS disease was not prevented., Competing Interests: The authors have no funding or conflicts of interest to disclose., (Copyright © 2024 The Author(s).

Objective: In this study, we aimed to compare long-term physical and mental health outcome between SARS-CoV-2 infected and uninfected household members to differentiate between infection-related and pandemic-related outcomes after about two and a half years of the pandemic. Furthermore, possible differences in the outcome of adults and children and young people (CYP) were of interest., Design: In a cross-sectional study design, we compared the long-term physical and mental health outcome of between infected and uninfected as well as between adult and CYP (household members)., Setting: The FamilyCoviDD19 study-a serology study in households-was initially conducted to evaluate virus transmission in a close contact setting focusing on households with children and adolescents in Germany. At least 1 year after initial infection in the respective households, a follow-up took place in which the prevalence and type of possible long-term consequences were surveyed on the basis of self-reported information on physical and mental health., Participant: In this study, a total of 533 household members of 146 families participated and responded to our survey, including 296 (55.5%) adults and 237 (44.5%) CYP., Result: The difference in frequency of reported symptoms between infected and uninfected individuals was very moderate, suggesting that the vast majority of reported symptoms were not attributable to a previous SARS-CoV-2 infection. However, regardless of age and infection status, this study showed overall high rates of self-reported symptoms with CYP having fewer long-term sequelae than adults one year after infection. Furthermore, over 50% of those reporting symptoms were not affected in their daily life, with CYPs reporting an even lower percentage compared with adults., Conclusion: CYP are at reduced risk not only to develop symptomatic infection or severe disease courses (previous analyses) but also to develop infection-associated long-term sequelae (this study). Independent of infection CYP reported high rates of neurocognitive, pain, somatic and mood symptoms, which makes the influence of the pandemic itself-including pandemic control measures-decisive., Competing Interests: Competing interests: AD, RB and JPA report grants from Federal State of Saxony during the conduct of the study.
