Build on existing PARI outpatient syndromic surveillance by adding laboratory multiplex testing of LRTI samples (RSV, Influenza, SARS-COV-2) 2. Follow all bronchiolitis through the PARI RWE database and document patient journey for 5 years after first medical visit 3. Review the electronic PARI data of three previous seasons in order to document the impact of LRTI attributable to RSV in children < 2 years in France prior to enhanced surveillance
