CENTRAL NERVOUS SYSTEM INFECTION BY GROUP A STREPTOCOCCUS IN CHILDREN IN SPAIN (2019-2023).

Central nervous system infections in children caused by group A Streptococcus are rare. This study, conducted across 52 hospitals in Spain from 2019 to 2023, identified 32 cases of central nervous system infections in children caused by group A Streptococcus, with a significant increase from October 2022 onward (1.1% vs.

Clinical, microbiological, and molecular characterization of pediatric invasive infections by in Spain in a context of global outbreak.

Unlabelled: In December 2022, an alert was published in the UK and other European countries reporting an unusual increase in the incidence of infections. Our aim was to describe the clinical, microbiological, and molecular characteristics of group A invasive infections (iGAS) in children prospectively recruited in Spain (September 2022-March 2023), and compare invasive strains with strains causing mild infections. One hundred thirty isolates of causing infection (102 iGAS and 28 mild infections) were included in the microbiological study: typing, antimicrobial susceptibility testing, and sequencing for core genome multilocus sequence typing (cgMLST), resistome, and virulome analysis.

Clinical outcomes and antibody transfer in a cohort of infants with in utero or perinatal exposure to SARS-CoV-2 (Coronascope Study).

Unlabelled: We aimed to describe the outcomes, focusing on the hearing and neurological development, of infants born to mothers with COVID-19 during pregnancy and to evaluate the persistence of maternal antibodies in the first months of life. An observational, prospective study at a tertiary hospital in Madrid (Spain) on infants born to mothers with COVID-19 during pregnancy between March and September 2020 was conducted. A follow-up visit at 1-3 months of age with a physical and neurological examination, cranial ultrasound (cUS), SARS-CoV-2 RT-PCR on nasopharyngeal swab, and SARS-CoV-2 serology were performed.

Clinical spectrum of COVID-19 and risk factors associated with severity in Spanish children.

We aimed to identify the spectrum of disease in children with COVID-19, and the risk factors for admission in paediatric intensive care units (PICUs). We conducted a multicentre, prospective study of children with SARS-CoV-2 infection in 76 Spanish hospitals. We included children with COVID-19 or multi-inflammatory syndrome (MIS-C) younger than 18 years old, attended during the first year of the pandemic.

Severe Acute Respiratory Syndrome Coronavirus 2 Vertical Transmission from an Asymptomatic Mother.

In utero transmission of severe acute respiratory syndrome coronavirus 2 infection is a point of debate. We report a case of severe acute respiratory syndrome coronavirus 2 vertical transmission from asymptomatic mother, with molecular detection in mother's blood at delivery and neonatal nasopharyngeal swabs at 5 and 28 hours of life and later IgG seroconversion. The newborn was asymptomatic.
