102 Discussion The strength of our study is that we performed routine pre-transplant screening for res- piratory viruses in all patients, including those with assumed high risk factors for severe RSV disease such as cord-blood transplant, young age, severe lymphopenia and neu- tropenia. 7 This study is limited by the small number of patients. We cannot exclude there is a subgroup of patients with increased risk of severe RSV-infection. In short, there was no case of severe RSV infection in 310 high-risk HCT recipients wit- hout specific treatment. The excellent outcome supports a restrictive policy in the use of preventive or antiviral treatment. 6
