Pandemic influenza A (H1N1) outbreak among 15 school-aged HIV-1-infected children.

Patients infected with human immunodeficiency virus type 1 (HIV-1) are considered to be at increased risk for 2009 H1N1 influenza-related complications. We performed an observational study after an outbreak of 2009 H1N1 influenza virus infection among a group of 15 HIV-1-infected school-aged children in Germany in October 2009. Clinical course, kinetics of viral shedding, and antibody response among children with CD4 cell counts >350 cells/μL and 2009 H1N1 influenza virus coinfection did not appear to differ from that among healthy children. Oseltamivir shortened the duration of viral shedding.
