Abstract

Between May and June of 2009 we observed 4 patients that presented with severe influenza-like symptoms and respiratory failure. All cases tested negative for influenza A and B by direct fluorescent antibody assay. Further investigation revealed all cases to be positive for pandemic (H1N1) 2009 influenza virus by real-time RT-PCR. This article includes a description of these cases and the characteristics associated with them.
