“The data in the DPH report are preliminary and subject to change.  At this point in the pandemic, local health departments may hear about a case of COVID-19 directly from a hospital or a medical provider before the DPH receives the laboratory report.  For this reason, a local health department’s COVID-19 case data may be more up to date than the DPH town-level data on a given day.  When this happens, we are asking our local health department colleagues to call the DPH Epidemiology Program and provide the case information to one of our epidemiologists and we will enter the case information into the surveillance database.” – CT DPH
