We aimed to estimate the respiratory syncytial virus positivity rate among ambulatory children with bronchiolitis according to the bronchiolitis epidemic period as defined by the French Public Health Institute. The positivity rate was 28.9% during the nonepidemic period and 50.

Objectives: We evaluated the burden of noninvasive group A Streptococcus (GAS) infections in ambulatory pediatrics before and during the COVID-19 pandemic in France.

Methods: We analyzed data from a national network of ambulatory pediatricians between 2018 and 2022. Clinicians evaluating children ≤15 years old for tonsillopharyngitis, perianal infections, paronychia/blistering dactylitis, and scarlet fever were invited to perform a rapid antigen detection test (RADT) for GAS.

Article Synopsis
  • The study examines the impact of non-pharmaceutical interventions (NPIs) during the Covid-19 pandemic on pediatric infectious diseases in France.
  • Data from 107 pediatricians showed a significant decrease in recorded infectious diseases in 2020 compared to 2018-2019, with a notable reduction in conditions like scarlet fever and bronchiolitis.
  • In 2021, a rebound in certain infections was observed, exceeding pre-pandemic levels, emphasizing the importance of ongoing monitoring of infectious diseases post-NPIs.

Background: Many ambulatory networks in several countries have established syndromic surveillance systems to detect outbreaks of different illnesses. Here, we describe a new Pediatric and Ambulatory Research in Infectious diseases network that combined automated data extraction from the computers of primary care pediatricians.

Methods: Pediatricians who used the same software, AxiSanté 5-Infansoft for electronic medical records were specially trained in infectious diseases, encouraged to comply with French treatments' recommendations, use of point-of-care tests and vaccination guidelines.

Article Synopsis
  • A total of 52,588 RT-PCR tests for SARS-CoV-2 were conducted in France from March 2 to April 26, 2020, with 6,490 tests in children and 46,098 in adults.
  • The positivity rate for SARS-CoV-2 was 5.9% in children compared to 20.3% in adults, indicating children had a lower rate of infection.
  • The overall risk ratio for adults testing positive compared to children was 3.5, suggesting adults were significantly more likely to test positive throughout the study period.

Papillomavirus (HPV), the first sexually transmitted disease in the world, is the main infectious agent responsible for cancer (6300 per year, in France). The cycle of HPV infection - >precancerous lesions - >cancer is well documented with regard to the cervix (cf. Nobel Prize in 2008).

Background: Pneumococcal conjugate vaccine (PCV) implementations led to major changes in serotype distribution and antibiotic resistance in carriage, accompanied by changes in antibiotic consumption.

Objectives: To assess the dynamic patterns of antimicrobial non-susceptibility across non-PCV13 serotypes following PCV implementations.

Methods: We conducted a quasi-experimental interrupted time series analysis based on a 17 year French nationwide prospective cohort.

Background: To re-evaluate antibiotic strategies for acute otitis media (AOM) in young children, we analyzed the trends of nasopharyngeal carriage and antibiotic resistance of Streptococcus pneumoniae (Sp), Haemophilus influenzae (Hi) and Moraxella catarrhalis (Mc) isolated from young children with AOM during a 16-year period.

Methods: This cross-sectional study analyzed from 2001 to 2016 the nasopharyngeal carriage of Sp, Hi and Mc of young children with AOM. Medical history and physical findings were reported.

Vaccination status is more often evaluated by up-to-date vaccination coverage rather than timeliness of immunization. Delaying vaccination may be dangerous during infancy. The aim of this study was to identify the importance of potentially dangerous vaccination delay (previously defined) and determinants of these delays.

The clinical impact of enteroviruses associated with hand, foot and mouth disease (HFMD) is unknown outside Asia, and the prevalence of enterovirus A71 (EV-A71) in particular might be underestimated. To investigate the prevalence of enterovirus serotypes and the clinical presentations associated with HFMD in France, we conducted prospective ambulatory clinic-based surveillance of children during April 2014-March 2015. Throat or buccal swabs were collected from children with HFMD and tested for the enterovirus genome.
