Ward placement of hospital-acquired influenza patients during incubation period, symptom onset, diagnosis and maximum 45 days following diagnosis. Note: an uncoloured ‘I’ indicates the patient was not in hospital on this day. 45 days following diagnosis was chosen as the limit of the inclusion period due to the maximum documented influenza viral shedding period in immunocompromised patients of 44 days [20]
