Following the occurrence of a large number of cases of influenza‐like illness in a rehabilitation community for drug users, between February and March 2004, surveillance activities were implemented. Attack rates of influenza‐like illness were calculated, and risk factors for the development of disease and complications were evaluated through the use of relative risks (RR) with 95% confidence intervals (CI). Nasal‐pharyngeal samples were collected for virological studies. Of 1,310 persons who were living in the community, 209 were diagnosed with influenza‐like illness: the attack rate (15.9% overall) was higher for HIV‐infected persons (RR: 1.77, 95% CI: 1.32–2.37), older individuals, and dormitory residents. HIV‐infected participants were also more likely to develop complications compared with HIV‐uninfected persons diagnosed with influenza‐like illness (RR: 5.13, 95% CI: 2.52–10.20). The outbreak was attributable to Christchurch‐like influenza A strains. Vaccination was ineffective because of the mismatch between wild and vaccine strains. J. Med.
