Enter the Enterovirus
The recent outbreak of human enterovirus 68 (EV-D68) poses several challenges to syndromic surveillance. Its presentation can resemble any number of other upper respiratory infections of varying severity. The timing coincided with the end of school summer vacation, a time of year when respiratory illnesses are always spread. Differentiation based on key symptoms is theoretically possible, but also highlights where the assumptions of surveillance on chief complaints can break down. And while the outbreak received national media coverage, the lack of a memorable consensus on what to call the pathogen may have limited patients’ and registrars’ ability to ask for it by name.
