Although this infection has been relatively mild in most individuals, a number of people have
required hospitalisation. To monitor clinical severity, an enhanced surveillance system collecting
detailed daily clinical information on laboratory confirmed cases requiring hospitalisation has
been introduced. These data allow us to monitor the clinical presentation of these patients,
identify risk factors, and the clinical outcome.
A total of 1539 individuals with confirmed H1N1v infection have ever been admitted to hospital
(as at midday 15 February). During the last week no person was admitted to hospital. Over the
last four weeks the rate of hospitalisations in all age groups has fallen.
A high proportion of patients ever admitted to hospital were known to have underlying diseases,
including chronic respiratory disease, diabetes or immunosuppression. The majority of patients
have now been discharged (1526/1539; 99%). Of the 13 patients who remain in hospital (as at
midday 15 February), 4 are being managed in intensive care, none in high dependency and 9
are being managed within general wards.

Cumulative numbers of hospitalisated patients
Please note that the number of hospitalised cases reported in week 53 reflects a delay in reporting due to the holiday period.
The age and sex profile is available for all patients admitted to hospital. The highest number of
hospitalisations is among those aged less than 25 years (681/1539, 44%), particularly in those
0-4 years of age (267/1539, 17%). Cumulatively, there are now slightly more women than men
who have been hospitalised during the period of monitoring.
