Wilton's First Selectman says there is an issue with the availability of case data on COVID-19 from the state.  Lynne Vanderslice says the Wilton Public Health Department is aware of at least 20 laboratory-confirmed cases while the state Department of Public Health indicates there are 17.  At this point in the pandemic, local health departments will hear about cases directly from hospitals and providers that the state does not know about.  Vanderslice says anyone who has received a confirmed or presumptive positive test and not contacted by the Wilton Health Department, is asked to call the department.
