MMWR Week Description and Corresponding Calendar Dates (2006-2020)

The MMWR week is the week of the epidemiologic year for which the National Notifiable Diseases Surveillance System (NNDSS) disease report is assigned for the purposes of MMWR disease incidence reporting and publishing. When a notifiable disease case is reported to the state or local health department, it is assigned (coded) to an MMWR Week. (1)

MMWR Week does not fall on the same dates every year. MMWR weeks last from Sunday through Saturday and usually range from 1 to 52. Depending on how the days of the week fall across years, it is possible to occasionally have a Week 53. Week #1 of an MMWR year is the first week of the year that has at least four days in the calendar year.

Disease Reporting Dates


Traditionally, state health departments collect a number of types of dates that are relevant to the incident case and its management. For NNDSS reporting, these dates have been assigned to a hierarchy as follows:

  • Date of disease onset
  • Date of diagnosis
  • Date of laboratory result
  • Date of first report to public (community) health system
  • State or MMWR report date
