RV is the second most common pathogen associated with bronchiolitis and is isolated all year round. This may be important in those with risk factors resulting in prolonged LOS. Further research is necessary to establish the exact role of RV in this common condition, particularly outside the traditional RSV season.

Respiratory tract infections (RTIs), including community-acquired pneumonia (CAP), bronchiolitis, viral-induced wheeze and croup, account for more primary care consultations than any other illness group and are the most likely reason for a parent or carer to contact a health professional. The majority of RTIs in fully immunised children are usually self-limiting. However, in a small percentage of children RTIs may become life threatening and it is crucial that all front-line health professionals are able to recognise and identify these children who are at risk of deterioration. To ensure this, fast recognition of symptoms is important, with care taken to exclude any 'red flag' features that may prompt a referral to secondary care. Nurses are well placed to reassure and support families, and to provide education regarding the facts about fever, the appropriate use of a single antipyretic medication, how to avoid dehydration in children with RTIs, and the beneficial role of immunisation in preventing infection. It is also important to explain in cases of CAP where antibiotics are necessary about how soon to expect a response, any side effects from antibiotics, and to provide 'safety net advice' on when to consider reassessment for the child. An illustrative case study is included to highlight some of the challenges that are likely to be encountered in clinical practice.
