Cases of Pertussis Reported to the Alaska Section of Epidemiology by Region, by Month, 2015
- Counts reflect total of confirmed and probable cases based on CDC case definitions: http://wwwn.cdc.gov/NNDSS/script/conditionsummary.aspx?CondID=113.
- Cases are assigned by date of onset, diagnosis, or report - whichever is earliest; therefore, case counts may be updated as new data become available.
- By national convention, cases are assigned by patient residence.
- Areas with low or no case counts may reflect absence of testing rather than absence of disease.
