[Influenza A(H1N1)v-patients treated in Oulu University hospital].
BACKGROUND
In Finland, the pandemic A(H1N1)v-influenza was experienced in late 2009.


METHODS
A(H1N1)v-patients hospitalized in Oulu University Hospital were evaluated.


RESULTS
Altogether, 159 A(H1N1)v-patients, including 37 children, were hospitalized. Their median age was 35. Eighteen (11 %) patients required admission to ICU; three of them died. As many as 62% of the patients suffered from radiologically confirmed pneumonia. The incidences of hospitalization, ICU care and death were 40,5, 4,6 and 0,8 per 100000, respectively.


CONCLUSIONS
Despite the low mortality rate, a rather high number of patients required hospitalization. Findings in chest radiography were common and prominent.
