STL polyomavirus (STLPyV) was recently identified in human specimens. To determine seropositivity for STLPyV， we developed an ELISA and screened patient samples from 2 US cities (Denver， Colorado [500]; St. Louis， Missouri [419]). Overall seropositivity was 68%-70%. The age-stratified data suggest that STLPyV infection is widespread and commonly acquired during childhood.
