Included six notifiable diseases reported frequently from 2001 to 2006.
Compared proportion notified within recommended time limits and calculated median time lags.
Analyzed time lags between symptom onset and notification to Korea Centers for Disease Control and Prevention.
Proportion of timely case reporting was lower for diseases with a 1-day limit compared to a 7-day limit (60%-70% vs. >80%).
Median time from onset to notification ranged from 6 to 20 days.
Main delays were identified from onset to diagnosis, suggesting variations in timeliness by disease and surveillance steps.
