Beginning October 14, 2009, the Department of Public Health will begin reporting laboratory-confirmed cases of H1N1 identified by "wave". Historically, pandemics occur in three waves. The first wave of the 2009 pandemic began in April 2009 and peaked in June 2009. The beginning of the reporting period for the second wave of the pandemic is August 30, 2009. The second wave of the pandemic is expected to peak in the fall of 2009. By reporting the number of laboratory-confirmed cases by wave, it allows you to see where we are in the pandemic wave, and how severe it is.
Laboratory-confirmed cases represent only a fraction of the likely number of cases in the state because many persons with mild symptoms do not seek care from a doctor or hospital but recover at home.
Connecticut's Hospital Emergency Department Syndromic Surveillance (HEDSS) System
Connecticut's Hospital Emergency Department Syndromic Surveillance (HEDSS) System, developed in 2004, receives daily electronic reports from more than half of Connecticut's acute care hospitals. Data include a listing of total patient visits with information on their town of residence and chief complaint.
