13 TIMELINESS OF REPORTING Timely reporting of infectious diseases is important in identifying potential outbreaks and in reducing disease burden. Public health relies on health care providers and laboratories for identification and prompt reporting of these infectious diseases. Timeliness requirements for each reportable disease is dependent of the infectious nature and severity of the disease. Reporting lag is defined as the difference between the date the case was reported to the local health department and the date of diagnosis. For Class A diseases, median and mean lag time values should be less than since these illnesses are required to be reported to the health department immediately, and for Class B and C diseases, mean and median lag time values should be less than since these illness should be reported to the health department by the end of the next business day. Table illustrates the lag time for select reportable diseases reported in Union County during 7. Table.
