Article Synopsis
- Paediatric acute bronchiolitis is typically seasonal, occurring from October to April in the northern hemisphere, but COVID-19 preventive measures led to a decrease in cases during the 2020-21 season.
- A study involving 6,334 infants in Spain examined the epidemiological changes in acute bronchiolitis cases before, during, and after COVID-19 interventions from September 2021 to August 2023.
- The findings revealed unexpected out-of-season peaks in bronchiolitis cases in the summers of 2021 and 2022, along with significant increases in hospitalization metrics in 2022-2023 compared to prior seasons.

August 2024
Article Synopsis
- The EPICO-SEHOP platform in Spain collects COVID-19 data specifically from children, comparing those with cancer or recent stem cell transplants to those without underlying health issues.
- Findings show that children with cancer or who have undergone stem cell transplants generally experience milder COVID-19 symptoms (7.1%) compared to those without comorbidities (14.7%), unless they had a recent transplant (less than 300 days), where 35.7% faced severe illness.
- The shared data aims to inform treatment and isolation strategies, emphasizing the role of collaborative registries in addressing health crises during the pandemic.

June 2022
Article Synopsis
- A study involving 13 hospitals in Spain examined the transmission of SARS-CoV-2 to newborns and included data from 177 infants exposed during pregnancy.
- Results showed 5.1% of the newborns tested positive for SARS-CoV-2, with 1.7% of cases attributed to intrauterine transmission and 3.4% to transmission during delivery or shortly after birth.
- Most infected newborns were either asymptomatic or had mild symptoms, and maternal factors did not significantly affect the risk of transmission, despite the presence of the virus in urine and meconium samples.
