The study design is a case-control, sample based study. 275 cases (Group 1), infants \<12 months old with RSV infection and 40 controls (Group 2), otherwise healthy infants \<12 months old without RSV infection will be recruited. Samples will be taken on enrolment and for infants in Group 1; repeated at 7 weeks convalescence. There will be annual follow up by questionnaire for up to 6 years and a minimum of 1 year, depending at what stage in the study the infant is enrolled.

Antibiotic resistance is an increasingly serious problem in Switzerland which is associated with the exposure and overall uptake of antibiotics in a population. Reduced antibiotic prescribing for outpatients is paralleled by a decrease in antibiotic resistance rates. In a recent pragmatic trial, the investigators found only promising yet not very conclusive results as those were present only in some groups. This nationwide antibiotic stewardship program with routine feedback on antibiotic prescribing was not associated with an overall change in antibiotic use. In older children, adolescents, and younger adults fewer antibiotics were prescribed, but not consistently over the entire intervention period. Hence, the investigators now aim to evaluate a better-tailored program to obtain a better understanding of the effects on patient-relevant outcomes, antibiotic resistance, and the underlying mechanisms leading to different effects in certain subgroups of patients. The investigators plan to evaluate a nationwide antibiotic stewardship program combining routine prescription feedback with the provision of physician and patient education material for primary care physicians in Switzerland. The project is conducted within the framework of the National Program on antimicrobial resistance by the Swiss National Science Foundation. Also, additional subprojects will be done where we will assess the impact of COVID-19 on AB prescription by comparing the years 2017,2018, and 2019 with the year 2020 data.
