Fatal pneumonia in an adult due to respiratory syncytial virus

Abstract

Respiratory syncytial virus (RSV) infections in adults are generally mild, and no fatalities in uninstitutionalized adults have been reported. To our knowledge, we document herein the first case of fatal RSV pneumonia in a previously healthy elderly woman living at home, in whom complement fixation titers against RSV rose from less than 1:8 to reach 1:256 at death. Cytoplasmic inclusions characteristic of RSV were detected at autopsy.
