Aim Respiratory syncytial virus ( RSV ) infections are among the most common lower respiratory tract infections in infants, but few studies have determined the age‐specific incidence of hospitalisation in defined populations. This study gathered Swedish data on RSV in Gothenburg and its 10 surrounding municipalities from 2004 to 2011. Methods Information was obtained from hospital databases of all patients up to five years of age who had a discharge diagnosis of an RSV infection and had a positive antigen detection or polymerase chain reaction test. Results A total of 1764 children fulfilled the inclusion criteria and 238 of these were preterm. The incidence under one year of age was 17.4/1000/year, and in children aged one to four years it was 0.6/1000/year. RSV patients occupied a mean of 1141 hospital beds per year: 65 were treated in the intensive care unit, 27 needed ventilator support, 19 needed continuous positive airway pressure, 408 (23%) received antibiotics, 399 (23%) received steroids, and all but four patients received a bronchodilator. All children survived. Conclusion The incidence of RSV infections was high, medication use was high, and complications were low. Preterm infants had a higher risk, but most infants needing hospitalisation for RSV are full term and have no known risk factors.
