Abstract

Background: In January 2013, a residence for mentally disabled persons reported a suspected outbreak of influenza. We carried
out an outbreak investigation to describe the outbreak and to recommend control measures.
Methods: We conducted descriptive epidemiology of the outbreak; a case was a resident or staff of the residence for mentally
disabled with fever (≥380C) and cough and/or sore throat between 25 and 29 January 2013. Specimens were tested for respiratory
pathogens, including influenza viruses. Control measures were taken to contain the infection.
Results: A total of 13 persons presented with influenza–like illness symptoms, the aetiology proved influenza A (H3N2) virus.
Two persons were hospitalized due to severe pneumonia. The overall attack rate was 17%. The first cases were among staff. The
residents were ill at the peak of the outbreak, and among staff the presentation was more dispersed. None of the staff and only
five of the residents had been vaccinated.
Conclusions: Staff possibly have initiated and contributed to the maintenance of transmission. We highlight the need to
comply with vaccination recommendations, especially for staff working with persons with risk factors.
